With a substantial development of research and findings for breastfeeding over the past three decades, we are now able to expand on the health benefits for both women and children across the globe. The two papers in this Series will describe past and current global trends of breastfeeding, its short and long-term health consequences for the mother and child, the impact of investment in breastfeeding, and the determinants of breastfeeding and the effectiveness of promotion interventions.
New Research Shows That Breastfeeding Matters Everywhere and Could Save Millions of Lives and Dollars
"Political commitment and investment in breastfeeding by governments, donors, employers and civil society is urgently needed to ensure the health of women and children and to shape a more sustainable future for all. UNICEF and the World Health Organization, in partnership with close to 20 organizations, are leading the charge to mobilize global action to raise political and financial investment to support breastfeeding. Together, we are working to remove barriers to breastfeeding and to give women the tools they need to make informed decisions to ensure their health and the health of their children for generations come."

Study of Ultrasonic Hydration Monitor for Neonatology and Pediatric Children and Infants and/or Children up to Age 3 Years Old With Diarrhea
Study will verify ability of infant Hydration Monitor (IHM) to assess changes of hydration status in newborns and infants by means of ultrasound velocity measurements through muscle tissues. Changes of tissue hydration will be followed during first days of life in newborns and in acute diarrhea in small children during re-hydration therapy. Weighting and clinical dehydration symptoms will be used as controls.
Handheld device to diagnose newborn dehydration
Noune Sarvazyan and her team at Artann Laboratories in the U.S. are developing a hand-held ultrasonic device to measure water content in the soft tissue of newborns and diagnose dehydration, one of the leading causes of infant morbidity and mortality in the developing world.
Infant Feeding Support for Refugee Children – #SafelyFed
Infant Feeding Support for Refugee Children is a group of mothers and other interested people, working as volunteers, to gather and co-ordinate support for the infants (newborns to age two years old and beyond) fleeing war and thus caught in the refugee crisis. As a group we support the WHO recommendations on Infant Feeding
whereby milk, preferably mother’s milk, should be the only food given for the first six months and milk feed should be offered freely for a minimum of two years.
• support mother & infant
• educate, train & support volunteers
• educate public
• support IYCF-E aligned groups to fundraise
The Global Enteric Multicenter Study (GEMS) is the largest, most comprehensive study of childhood diarrheal diseases ever conducted in developing country settings. Globally, diarrheal diseases are the second leading cause of death among children under five, despite the existence of effective interventions, such as oral rehydration solutions (ORS) and zinc supplements as general treatments. Many different bacteria, viruses and other pathogens can cause diarrheal disease. However, it has been difficult to prioritize and target interventions because previous studies cannot be easily compared or combined due to differences and limitations in the methods used. By studying more than 22,000 children (9,439 cases and 13,129 controls) across two continents with consistent methods, GEMS provides important, new data that will help researchers, policymakers, donors and advocates make evidence-based decisions to help to reduce the global burden of diarrheal diseases.

Treatment of diarrhea in young children: results from surveys on the perception and use of oral rehydration solutions, antibiotics, and other therapies in India and Kenya
Journal of Global Health - 2013 June; 3(1): 010403. - doi: 10.7189/jogh.03.010403
Diarrheal disease is a leading cause of morbidity and mortality among children under five. Although oral rehydration solution (ORS) has tremendous therapeutic benefits, coverage of and demand for this product have remained low in many developing countries. This study surveyed caregivers and health care providers in India and Kenya to gather information about perceptions and use of various diarrhea treatments, assess reasons for low ORS use, and identify opportunities for expanding ORS use.
"Children are dying for lack of basic healthcare knowledge among citizens and health workers, and this is especially true of children with diarrhoea. Previous studies have shown that only 1 in 10 children with diarrhoea in India receive increased fluids to prevent death from dehydration, contributing to more than a million deaths every year. Almost 4 in 10 receive less to drink than normal, thereby tragically *increasing* their risk of death as compared with carrying on as normal. By contrast, more than 1 in 3 are inappropriately given antibiotics, which are not generally recommended for childhood diarrhoea.
A thousand children die needlessly from diarrhoea every day in India alone, due to basic errors in care from parents and health workers.
See: This new paper from India and Kenya provides further cause for concern... More than 90% of all diarrhea deaths could potentially be avoided with universal coverage of ORS - A million children are dying unnecessarily from diarrhoea every year because of lack of basic healthcare knowledge... How can we do better to improve the knowledge of citizens and health workers to manage child diarrhoea more effectively?" Join HIFA2015 and Discuss - It's Free!

Findings published in
The Lancet can guide prevention, treatment and research on diarrheal diseases, which claim the lives of 800,000 children annually
15 MAY 2013 — WHO - A new study published in The Lancet has pinpointed the primary causes and impact of diarrheal diseases—a leading cause of deaths among children globally—and has revealed new opportunities for intervention. The Global Enteric Multicenter Study (GEMS) is the largest study ever conducted on diarrheal diseases in developing countries, enrolling more than 20,000 children from seven sites across Asia and Africa.
GEMS, coordinated by the University of Maryland School of Medicine’s Center for Vaccine Development, confirmed rotavirus – for which a vaccine already exists – as the leading cause of diarrheal diseases among infants and identified other top causes for which additional research is urgently needed. GEMS found that approximately one in five children under the age of two suffer from moderate-to-severe diarrhea (MSD) each year, which increased children’s risk of death 8.5-fold and led to stunted growth over a two-month follow-up period.

The Lancet Series on Childhood Pneumonia and Diarrhoea, led by Aga Khan University, Pakistan, provides evidence for integrated control efforts for childhood pneumonia and diarrhoea. The first paper assesses the global burden of these two illnesses, comparing and contrasting them, and includes new estimates of severe disease and updated mortality estimates for 2011.
Findings from the second paper show that a set of highly cost-effective interventions can prevent most diarrhoea deaths and nearly two thirds of pneumonia deaths by 2025, if delivered at scale. Furthermore, the paper estimates what the cost of scale up will be.
The third paper presents the results of consultations with several hundred frontline workers in high-burden countries and explores the barriers and enablers they face in dealing with these two diseases and potential ways forward.
The final paper represents a call to action and discusses the global and country-level remedies needed to eliminate preventable deaths from these illnesses by 2025.
Integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD), a new global plan from UNICEF and WHO, represents the first-ever simultaneous effort to protect children from pneumonia and diarrhoea, the two leading killer diseases of children less than five years old.
Mind the GAPPD — A Pivotal New Resource Offers Global and Local Strategies to Overcome Leading Child Killers
11 April 2013 - This week, we celebrate integration. Though it is intrinsically at the heart of what we and our partners do in addressing myriad global health challenges through thoughtful, efficient strategies, today integration is particularly at the fore. For the very first time, there is a global plan to simultaneously take on the two diseases killing more than 2 million young children each year: pneumonia and diarrhea.

29 October 2012 – If you don’t work in global health you might be surprised to learn that fighting the leading killers of children has not been a global priority. You might also be surprised to learn exactly what the leading killers of children under 5 are – two diseases, pneumonia and diarrhea. These two kill more children under 5 than AIDS, malaria and measles combined. They cause 2 million children to die every year and account for a massive 30% of all under 5 deaths. And yet they attract less than 5% of global health funding.
To add insult to injury we have very cost effective vaccines, antibiotics and other treatments like oral rehydration salts and zinc that can prevent and treat the leading causes of pneumonia and diarrhea. If we made them widely available, pneumonia and diarrhea would kill a fraction of the children that they do now. Vaccines alone have the power to prevent almost 1 million child deaths from pneumonia and diarrhea every year. When you add in antibiotics, oral rehydration salts, zinc and vitamin A supplements – each of which cost cents per dose – you can probably double that figure and wipe out almost all deaths.
| International Society for Social Pediatrics and Child Health (ISSOP) Position Statement on sponsorship of paediatricians/paediatric societies by the Baby Feeding Industry
Infant and young child feeding is central to child health and, after birth, breastfeeding is the first act of provision by a mother for her child. For most of history no other third party was required to support infant feeding other than the mother and the surrounding family. It is only since the commercial development of breast milk substitutes in the nineteenth century that health professionals have become involved in their prescription.
"In recent years, the commercialisation of infant feeding has impacted on professional practice through the development of sponsorship by the Baby Feeding Industry of medical conferences and meetings, along with gifts to health workers.
It is the view of ISSOP that this sponsorship is damaging to the reputation of paediatricians, to the health of mothers and infants, and to the status of breastfeeding and this statement explains the reasons why we believe that such sponsorship should be terminated."
>> Download ISSOP Position Statement
ISSOP is hopeful that the Position Statement will be used with paediatric societies and associations around the world to ensure that paediatricians and other health professionals avoid conflicts of interest, and protect breastfeeding as one of the most health promoting measures in the field of child health.
*The term Baby Feeding Industry refers to all commercial companies which market infant formula or other infant feeding products.
8 June 2012 – Preventing and treating pneumonia and diarrhoea – the two leading causes of death among children under five – can help save the lives of more than two million children, according to a report released today by the United Nations Children’s Fund (UNICEF).
“We know what works against pneumonia and diarrhoea – the two illnesses that hit the poorest hardest,” UNICEF’s Executive Director, Anthony Lake, said in a news release. “Scaling up simple interventions could overcome two of the biggest obstacles to increasing child survival, help give every child a fair chance to grow and thrive.”
Pneumonia and diarrhoea account for nearly one-third of the deaths among children under five globally – or more than 2 million lives each year. Nearly 90 per cent of deaths from pneumonia and diarrhoea occur in sub-Saharan Africa and South Asia.
The prevention and treatments for both diseases often overlap, and include such basic steps as: increasing vaccine coverage; encouraging breastfeeding and hand-washing with soap; expanding access to safe drinking water and sanitation; and disseminating oral rehydration salts to children with diarrhoea and antibiotics to children with bacterial pneumonia.

Towards ending preventable child deaths
Margaret Chan, Director-General of WHO and Anthony Lake, Executive Director of UNICEF "'We, as the leaders of WHO and UNICEF, are personally committed to the achievement of MDG 4 and new targets introduced through A Call to Action and A Promise Renewed. The two agencies will work in an even closer collaboration to support countries to achieve universal coverage of effective interventions - and effectively put an end to preventable child deaths."
Thanks in large part to the increased attention to maternal and child survival brought about by the Millennium Development Goals (MDGs), the world has made substantial progress in reducing child mortality over the past two decades. The number of deaths among children younger than 5 years has declined from more than 12 million in 1990 to 7·6 million in 2010. The mortality rate in children under 5 years has dropped from 88 deaths per 1000 livebirths in 1990 to 57 in 2010—a 35% reduction. The rate of decline in the under 5 mortality rate has accelerated from 1·9% a year from 1990 to 2000 to 2·5% a year from 2000 to 2010. The rate of reduction has doubled in sub-Saharan Africa. These gains underline the importance of having clearly defined targets, especially when they are combined with mechanisms for monitoring progress, ensuring equity, and promoting accountability.
Researchers Outline Plan to End Preventable Child Deaths in a Generation
From Johns Hopkins Bloomberg School of Public Health Preventable childhood deaths caused by illnesses such as pneumonia and diarrhea can be nearly eliminated in 10 years according to researchers from the Johns Hopkins Bloomberg School of Public Health and the National Institutes of Health. In a new commentary featured in the June issue of the Journal of the American Medical Association, researchers outline a strategy and benchmarks for curbing childhood preventable deaths and recommend a new common vision for a global commitment to end all preventable child deaths.

GHANA’S DUAL VACCINE LAUNCH MAKES HISTORY
May 2012 Two weeks ago,
made history by becoming the first African nation to simultaneously
introduce vaccines against pneumonia and diarrhea, the leading killers of
children. At PATH, it was a time not just to celebrate but to reflect on
and rewarding effort that made rotavirus vaccine introduction possible. Ghana’s successful introduction came directly on the heels of a
new Vaccine journal supplement that features an incredible finding:
rotavirus vaccines are projected to save 2.4

May 2012 A new publication in the Lancet presents encouraging news on the continued
decrease in global child deaths. From 2000-2010, deaths among children under five
dropped from 9.6 to 7.6 million per year, according to data gathered by
the Child Health Epidemiology Reference Group of the World Health
Organization and UNICEF. Despite these gains, childhood diarrhea and
pneumonia still claim a combined 2 million lives annually. The good news of decreases in child deaths are also coupled with an alarm
of children remain vulnerable despite proven and available interventions.
A coordinated approach to diarrhea and pneumonia control in the hardest-hit
countries, along with increased commitments to protect all children, offer
the most promise for helping global child deaths decrease even further.

Historic dual rollout of rotavirus and pneumococcal vaccines—a first for Africa
• Completion of training programs for tens of thousands of healthcare workers.
April 26, 2012—Today, Ghana made history. It became the first African country to simultaneously introduce vaccines against the primary causes of the two leading childhood killers worldwide—diarrhea and pneumonia. In Ghana, these killer diseases together account for approximately 20 percent of the country’s mortality in children under five years of age. The Expanded Program on Immunization Manager, Dr. K.O. Antwi-Agyei, decided that Ghana’s children could wait no longer for lifesaving vaccines and made the unprecedented decision to introduce both vaccines at once. "We could not introduce one vaccine and then wait—while our children were dying—to introduce the other. We have the systems and we have carefully planned the introduction process," said Dr. Anti-Agyei.
Preparations for the dual introduction were heroic and successful:
• Expansion of the cold chain to keep the vaccines cool in a tropic nation where electricity in rural areas is unreliable.
• Far-reaching public awareness campaigns taken to outreach centers in rural villages.
• Reissuance of millions of upgraded child health immunization cards.
Ghana has identified rotavirus vaccines as an essential and lifesaving intervention in its comprehensive diarrhea control strategy, thereby facilitating achievement of Millennium Development Goal 4—reduction of child mortality.
A lifeline for children across the African continent and beyond
27 September, 2011
GAVI approves rotavirus vaccine funding for 16 new countries, 12 in Africa Until today, life-saving rotavirus vaccines were not accessible for most
children in Africa, the continent with a staggering burden of rotavirus
disease and where vaccines are desperately needed to prevent severe
rotavirus diarrhea and save children’s lives: • Where nearly a quarter of a million children die of rotavirus disease each year.
• Where roughly 40% of children hospitalized for severe diarrhea have rotavirus.
• Where urgent care and treatment for severe rotavirus diarrhea is often limited or unavailable. Now there is a new story of hope and promise to tell about Africa—a
story of a future where children who need the vaccine most will have a
chance at a healthy and happy life, free from the threat of severe rotavirus disease. Today the GAVI Alliance approved rotavirus vaccine funding for 16 new
countries, 12 in Africa, including Angola, Burundi, Cameroon, Congo
DR, Djibouti, Ethiopia, Ghana, Madagascar, Malawi, Niger, Rwanda, and
Tanzania—and four other countries, including Armenia, Georgia, Moldova,
and Yemen. On July 17, 2011, Sudan became the
first African country to introduce rotavirus vaccines with GAVI
Alliance funding—just two years after the
World Health Organization recommended all countries introduce the
vaccine into their national immunization programs. People have heard
about Sudan’s introduction and have seen the news
around the world that vaccines against rotavirus are saving lives in
countries where children have access to them. They eagerly await the vaccine's arrival.
GAVI’s historic rollout of rotavirus vaccines in Africa begins today!
July 17, 2011
This morning, hundreds of infants
in Khartoum, Sudan received their first doses of vaccine that will help
prevent severe rotavirus and the deadly dehydrating diarrhea it causes.
Today marks a milestone in global health—the first nationwide introduction
of rotavirus vaccines by a GAVI-eligible African country. “We finally have
the vaccine in our hands; it is a great and exciting day in our lives and we
are happy that this is a reality now,” said Dr.
Amani Abdelmoniem Mustafa, the manager of the Expanded Programme on
Immunization (EPI). “We share our joy with our supportive partners at GAVI,
WHO, UNICEF, and PATH who are part of this victory over childhood diarrhea in Sudan.” Until today, life-saving rotavirus vaccines were out of reach of most children in Africa. South
Africa (which is not GAVI-eligible due to its higher income level)
introduced rotavirus vaccines in 2008 and 2009, and there are plans for many
other GAVI-eligible African countries to roll out rotavirus vaccines in the
next few years. GAVI’s commitment to support the introduction of rotavirus
vaccines in more than 40 countries by 2015, many in Africa, will reverse the
tragic story by preventing hundreds of thousands of unnecessary child deaths
from diarrhea across the African continent. Please click here for GAVI’s statement supporting the African introduction of rotavirus vaccines.

Scaling Up Diarrhea Prevention and Treatment Interventions: A Lives Saved Tool Analysis - Research Article Diarrhea remains a leading cause of mortality among young children in low- and middle-income countries. Although the evidence for individual diarrhea
prevention and treatment interventions is solid, the effect a comprehensive scale-up effort would have on diarrhea mortality has not been estimated. Using currently available interventions, we demonstrate that with improved coverage, diarrheal deaths can be drastically reduced. If delivery strategy
bottlenecks can be overcome and the international community can collectively deliver on the key strategies outlined in these scenarios, we will be one
step closer to achieving success for the United Nations' Millennium Development Goal 4 (MDG4) by 2015.
January 2011 -
The Pediatric Infectious Disease Journal special issue shows that rotavirus vaccines are improving the health and well-being of children by
substantially reducing severe and fatal diarrhea.
Real World Impact of Rotavirus Vaccination, a special supplement to the January 2011 edition of
The Pediatric Infectious Disease Journal, demonstrates the dramatic impact of rotavirus vaccines on children's health in both developed and
developing countries. Studies in the supplement show that in the two to three years following the roll-out of rotavirus vaccines in national
immunization programs, countries experienced striking and swift reductions in the number of children under five years of age hospitalized due to acute
diarrhea caused by rotavirus.
Disparities in the Treatment of Childhood Diarrhoea in India
Nisha Malhotra and Nicholas Choy
19 pages - 246 kb
Despite the severe impact of diarrhoea on children's health and mortality in India, recent surveys show that only half of all children suffering from
diarrhoea receive treatment or medical advice, and more than two-thirds receive no Oral Rehydration Therapy (ORT). An understanding of the
socio-demographic determinants for appropriate treatment of the disease will be critical for improving these figures. This analysis is based on the most
recent National Family Health Survey (NFHS3), which shows that children are more likely to receive ORT if they are treated in a public health facility,
rather than in a private health facility. Households with mothers belonging to the youngest age group, lowest educational attainment, and poorest wealth
index are the least likely groups to properly treat their children suffering from diarrhoea. A significant gender bias also exists as parents show a
preferential treatment of male children and delay seeking treatment for their female children. The low usage of ORT can also be attributed to a
combination of low health knowledge among the aforementioned groups, and low use of public health facilities.

How Do You Solve a Problem Like Diarrhea? Poop Jokes May Save Millions
of Kids a Year
Newsweek, October 2009
"There are two ways to try to draw attention to the oft-ignored issue of
diarrhea in the Third World. You can point out that it’s literally a dead
serious thing, an ailment that kills more than a million children under age 5
every year. Or you can use comedy in the service of tragedy─i.e., you can make
jokes about poop."

focused on diarrhea and pneumonia, the two most common but still neglected causes of child mortality.
Can One Pill Tame the Illness
No One Wants to Talk About?
17 August, 2009 - It is hard to grasp the impact diarrhea has on people's lives across Africa and Asia. The disease kills more children than either malaria or AIDS, stunts growth, and forces millions — adults and children alike — to spend weeks at a time off work or school, which hits both a country's economy and its citizens' chances of a better future.

Healing: The Unexpected Properties of Zinc
Scaling up oral rehydration salts and zinc for the treatment of diarrhoea
Scaling up the provision of zinc and ORS could rapidly reduce child mortality for four reasons.
Firstly, although it has been almost eight years since the World Health Organization recommended combination treatment with zinc and ORS, few countries have implemented basic interventions to increase the currently low use of adjunctive zinc. Such interventions would include marketing zinc to caregivers and distributing it in large volumes through both public and private facilities. Even limited additional investment in such interventions could have a large effect.
Secondly, children with diarrhoea can be reached and given appropriate treatment easily. Most children currently obtain some form of treatment for diarrhoea, but most of them receive inappropriate treatments such as antibiotics and antidiarrhoeal agents. Merely switching the treatments children receive, which is less challenging than trying to change caregivers' treatment seeking behaviour, could therefore drive substantial increases in ORS and zinc coverage.
Thirdly, and in contrast to treatments for malaria or pneumonia, effective treatment of diarrhoea does not need to be carefully targeted to selected children in whom a definitive diagnosis is made. A strategy of "flooding the market" with ORS and zinc distributing them through all outlets where caregivers seek treatment could be pursued safely, with no threat of drug resistance, for example.
Lastly, a full course of zinc and ORS treatment costs less than $0.50 (Â£0.3; €0.38), and the marketing, training, and distribution necessary to drive product uptake could also be implemented at comparatively modest cost. Moreover, public funding for procurement of zinc and ORS in many countries would be further moderated by the fact that most treatment for diarrhoea is delivered through the private sector and paid for out of pocket. >> more

Global advisory group notes efficacy of RotarixTM in Africa
review of the latest data on rotavirus vaccines, including preliminary
immunogenicity and clinical efficacy results from a Phase III study of the
RotarixTM vaccine in Africa, the World Health Organization’s
Strategic Advisory Group of Experts (SAGE) noted that RotarixTM
significantly reduced serious rotavirus gastroenteritis in challenging settings.
The study, which PATH is conducting in collaboration with the vaccine’s
manufacturer, GlaxoSmithKline (GSK), and investigators in South Africa and
Malawi, has been recently completed. Full results will be presented to SAGE at
its April 2009 meeting, at which time SAGE will consider whether the results
warrant establishing a global recommendation for the use of rotavirus vaccines.
Along with trials in Ghana, Kenya, Mali, Bangladesh,
and Vietnam to evaluate the clinical efficacy of RotaTeq® by Merck & Co., Inc.,
the GSK study speaks to an earlier SAGE recommendation that called for the
generation of safety and efficacy data on the vaccines’ use in developing
countries of Africa and Asia. Both rotavirus vaccines currently are prequalified
by WHO for use in developing countries of Latin America and Europe, where
previous clinical trials demonstrated their safety and efficacy. In November
2006, the GAVI Alliance pledged to provide financial support for the use of
rotavirus vaccines by developing countries in these regions as well.
WHO convenes experts to provide guidance on
extrapolating clinical trial data on rotavirus vaccines
The October 24, 2008, issue of the Weekly
Epidemiological Record (WER), published by the World Health Organization (WHO),
features a report on the outcome of a meeting of global, regional, and
country-level rotavirus experts and immunization opinion leaders who gathered to
provide guidance on evaluating and extrapolating clinical trial data on
Participants agreed that even vaccines with moderate
efficacy would bring about substantial public health benefits in developing
countries in Africa and Asia, where most rotavirus deaths occur, and would be
cost effective for saving children’s lives. The experts noted that criteria such
as the WHO mortality strata and local epidemiology of rotavirus infection are
useful for extrapolating clinical trial data to other regions and countries.
The meeting participants also deliberated about the research agenda for
candidate rotavirus vaccines under development.
The PATH Rotavirus Vaccine Program is collaborating
with GlaxoSmithKline and Merck & Co., Inc., to generate important efficacy data
through clinical trials in Bangladesh, Ghana, Kenya, Malawi, Mali, South Africa,
and Vietnam. Interim results from the South Africa trial are positive and
underscore the potential of rotavirus vaccines to have significant public health
impact in low-resource countries. Additional data will be available soon, and
results from all of the clinical studies in progress will be available in 2009.

Major surveillance study shows worldwide need
for rotavirus vaccines
Findings from a global surveillance network
measuring the burden of rotavirus disease were published this week in the Morbidity and Mortality Weekly Report
(MMWR) of the US Centers for
Disease Control and Prevention and in the Weekly Epidemiologic Record (WER)
of the World Health Organization. The hospital-based surveillance findings
indicate that, during 2001 to 2008, rotavirus accounted for approximately 40
percent of hospitalizations for diarrhea among children under five years of age
worldwide. To read the full reports, please visit MMWR November 21, 2008 /
Vol. 57 / No. 46 (http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5746a3.htm)
and WER 21 November 2008/ Vol. 83/ No. 47 (http://www.who.int/wer/en/).
The data in this study were collected as part of a
collaboration, beginning in 2001, of the World Health Organization,
international partners, and networks of hospital-based sentinel surveillance
sites for detection of rotavirus diarrhea and characterization of rotavirus
strains. The data were collected in sentinel hospital–based sites in 35
countries from each region of the world.
The study demonstrates the substantial burden of
rotavirus diarrhea worldwide and highlights the potential health impact of
vaccination. According to the authors of the MMWR, “The substantial
health burden of rotavirus diarrhea in the world underscores the need for
effective interventions (e.g., vaccines) for the control of this disease as part
of a comprehensive approach for prevention and control of diarrhea.”
The PATH Rotavirus Vaccine Program is collaborating
with GlaxoSmithKline Biologicals and Merck & Co to generate important efficacy
and safety data through clinical trials in Bangladesh, Ghana, Kenya, Malawi,
Mali, South Africa, and Vietnam. Data from clinical studies currently in
progress will become available in 2009. Results from these trials will provide
important information for WHO’s consideration of these vaccines for global use.
New studies show rotavirus vaccines have led
to dramatic reduction in US severe rotavirus disease
The use of rotavirus vaccines in the United States
has reduced hospitalizations for severe diarrhea by 70 to 80 percent and may
have prevented illness in unvaccinated children by limiting the number of
circulating infections. Several studies documenting these results will be
presented this week in Washington, DC, at a joint meeting of the Infectious
Disease Society of America (ISDA) and the Interscience Conference on
Antimicrobial Agents and Chemotherapy.
Before rotavirus vaccines were approved for use in
the United States in 2006, rotavirus caused 200,000 emergency room visits and
55,000 hospitalizations in the United States each year. Worldwide, rotavirus is
responsible for 2 million hospitalizations and more than 500,000 deaths annually
in children aged five years or younger. Nearly all rotavirus deaths occur in the
poorest parts of the world, and the dramatic impact of rotavirus vaccines in the
United States is a strong signal of their potential in saving lives globally.
Typically, it can take more than ten years for new
vaccines to reach the developing world, but rotavirus vaccines are rapidly
overcoming this barrier. Low- and middle-income countries in Latin America and
Eastern Europe have introduced or are considering introduction of rotavirus
vaccines, with subsidized support from the GAVI Alliance. Clinical trials among
impoverished populations in Africa and Asia also are evaluating the vaccines’
performance in these environments. Results expected in 2009 will inform
decision-making by both the World Health Organization and the GAVI Alliance.

Merck’s RotaTeq® vaccine earns WHO prequalification
WHO has placed RotaTeq®, the rotavirus vaccine manufactured by Merck & Co., on its
list of prequalified vaccines for purchase by UN agencies as of October
2008. WHO’s prequalification of RotaTeq® is a major step in accelerating the
availability of rotavirus vaccines in the developing world. The Rotarix® vaccine
manufactured by GlaxoSmithKline (GSK) achieved prequalification in January 2007.
“Vaccines are the best hope for preventing severe
rotavirus disease,” said John Wecker, PhD, Director of the PATH Rotavirus
Vaccine Program (RVP). “WHO’s prequalification of RotaTeq® is an important
milestone towards ensuring that rotavirus vaccines are accessible to children
RVP is collaborating with Merck and GSK to generate
important efficacy and safety data through clinical trials in South Africa,

New data show substantial progress against
rotavirus in the United States
New data, published today in the US Centers for
Disease Control and Prevention’s (CDC) Morbidity and Mortality Weekly Report
(MMWR), indicate a dramatic reduction in seasonal incidence of rotavirus
coinciding with increased use of rotavirus vaccine, which was recommended for US
infants in February 2006. CDC surveillance data indicate that seasonal incidence
of rotavirus dropped more than 50 percent during 2007-2008 in the US, and that
the current rotavirus season began two to four months later than usual. During
the first 18 weeks of 2008, only six percent of samples tested positive for
rotavirus, compared to 51 percent in 2006 and 54 percent in 2007 over the same
18-week period. Both the drop in magnitude and delay in seasonal onset coincide
with increasing use of rotavirus vaccines in the US.
The most common form of severe diarrhea in
children, rotavirus accounts for over 50,000 hospitalizations, more than 200,000
emergency department visits, and 410,000 physician office visits in the US
annually. Readily accessible medical care means that children in the US rarely
die from the disease; however, rotavirus is estimated to take the lives of more
then 500,000 children around the world each year, nearly all in low-income
PATH’s Rotavirus Vaccine Program (RVP) is a
partnership with the World Health Organization and the US CDC, funded by the
GAVI Alliance. By collaborating closely with the vaccine industry, public health
organizations, donors, and governments, RVP is working to make rotavirus
vaccines accessible to children worldwide.

Rotarix® rotavirus vaccine receives US FDA approval
On April 3, 2008, the US Food and Drug
Administration (FDA) approved GlaxoSmithKline’s (GSK’s) Rotarix® vaccine for
prevention of rotavirus in infants, providing an additional option for
protecting American children against this severe diarrheal disease. Data from
large-scale clinical trials conducted in the US, Europe, and Latin America
informed the FDA’s decision. Another rotavirus vaccine, RotaTeq®, manufactured
by Merck & Co., Inc., received FDA approval in 2006.
Rotavirus causes more than half a million childhood
deaths every year, but fatalities are rare in the US and other industrialized
countries, where acute medical care is readily accessible. The developing world,
however, carries a far greater burden of disease. Nearly 90 percent of all
rotavirus-related deaths occur in the world’s poorest countries, making
rotavirus vaccination an imperative public health intervention.
PATH’s Rotavirus Vaccine Program is working in
partnership with GSK and Merck on clinical trials of their respective vaccines
in Africa and Asia. These trials will generate valuable data for developing
countries considering the use of vaccines to reduce rotavirus mortality. They
are a pivotal element of a broad range of activities that PATH and its partners
are conducting to lay the foundation for accelerated introduction of rotavirus
vaccines in the developing world.

New resource to assist countries applying for
GAVI support of rotavirus vaccines
A new publication,
Introduction of rotavirus vaccine with support from the GAVI Alliance:
Information to assist the national decision-making and application process,
is now available. Developed by PATH in partnership with the GAVI Alliance and
the World Health Organization (WHO), this new resource summarizes the scientific
evidence and operational guidelines that countries need to consider in
preparation for introducing rotavirus vaccines. Along with data on the burden of
rotavirus disease and the efficacy, safety, and cost-effectiveness of the two
currently available rotavirus vaccines, the information pack addresses
eligibility criteria, application procedures, co-financing requirements, and
health system considerations for new vaccine introduction.
Intended as a supplement to
GAVI’s detailed guidelines, the document aims to support decision-making by
GAVI-eligible countries in the WHO European region, and it is also available in
Russian. Updates will be posted on GAVI’s website as new information becomes
available and in accordance with GAVI decisions on eligibility in other WHO regions.
Promising trial results add to evidence on rotavirus vaccination in Asia
Results released this week
from a clinical trial of GlaxoSmithKline’s Rotarix™ revealed significant immune
responses among Bangladeshi infants given the vaccine. In a study conducted at
the International Center for Diarrheal Disease Research, Bangladesh (ICDDR,B),
and supported by PATH, 57 to 67 percent of participants receiving the live, oral
vaccine developed an immune response, providing critical evidence of the
potential impact of rotavirus vaccine introduction in the region. The Phase 2,
double-blind, randomized, placebo-controlled study of 300 children was conducted
from June 2005 through January 2006.
In addition to testing the
immunogenicity of Rotarix™ in this setting, investigators at ICDDR,B also
evaluated the co-administration of the vaccine with oral polio vaccine (OPV) and
found that coadministration did not lower the polio immune response and that
Rotarix™ may be administered concomitantly with OPV. Because the performance of
oral vaccines can vary in different regions, WHO’s Strategic Advisory Group of
Experts (SAGE) has called for appropriately designed clinical trials of
rotavirus vaccines among infants in Asia and Africa as a prerequisite to
recommending global use.
To learn more about additional clinical studies PATH is supporting in Africa and Asia, please see the summary below.

WHO releases updated estimates of global rotavirus disease burden
WHO recently announced
updated estimates on the number of child deaths worldwide in 2004 that were
associated with rotavirus infection:
- 527,000 children under five years old died due to rotavirus infection, comprising 29 percent of all diarrhea-related mortality in this age group.
- Nearly 85 percent of child rotavirus deaths occurred in Africa and Asia.
- 23 percent of all rotavirus deaths under five years of age occurred in India; six countries (India, Nigeria, Democratic Republic of the Congo, Ethiopia, China,
and Pakistan) accounted for more than half of under-five rotavirus deaths.

European network established with surveillance initiated in four countries
The CDC’s latest issue of
Rotavirus Surveillance News outlines activities of the European regional
surveillance network. Data on the burden of rotavirus in Eastern Europe is
particularly important, as the region includes several countries that may be
early introducers of rotavirus vaccines subsidized by the GAVI Alliance. With
technical assistance from CDC and PATH, surveillance began in December 2006 in
Azerbaijan, Georgia, Tajikistan, and Ukraine. Activities in these countries
enabled the establishment of a regional network that also incorporates data
collected in Kyrgyzstan and Uzbekistan, which had previously initiated rotavirus
surveillance. To read more about the European regional rotavirus surveillance network,

February’s meeting of the CDC’s Advisory Committee on Immunization Practice are now available
The committee reviewed post-marketing safety surveillance data on RotaTeq®, the
rotavirus vaccine by Merck & Co., Inc. Because of a suspected association
between intussusception and the RotaShield® vaccine that was withdrawn from the
US market in 1999, the CDC is taking particular care to monitor adverse event
reports associated with RotaTeq®. The data reveal that cases of intussusception
reported since its introduction in early 2006 did not exceed the expected
background rate. For a detailed report of the meeting and the committee’s data
review, please see the

GlaxoSmithKline’s Rotarix® vaccine earns WHO prequalification
On January 30, 2007, WHO announced prequalification of the Rotarix®
vaccine manufactured by GlaxoSmithKline (GSK), marking the first time in
history that a rotavirus vaccine has been prequalified. This designation of
“acceptability in principle” will allow for purchase of the vaccine by United
Nations agencies and is a significant advance in the accessibility of
rotavirus vaccine for developing countries that depend on agencies like UNICEF
for drug procurement.
In issuing its decision, WHO noted the need for data on the vaccine’s safety
and efficacy in Africa and Asia before the product will be prequalified for
use in these regions. GSK is partnering with PATH to generate important
clinical data in trials conducted in Bangladesh, Malawi, and South Africa.
For further details, including provisions on Rotarix® packaging and
presentation, please see the notes on Rotarix® within WHO’s
list of prequalified vaccines.
FDA updates prescribing information on RotaTeq® vaccine
In a public
health notification issued February 13, the US Food and Drug
Administration (FDA) provided updated prescribing information for the RotaTeq®
vaccine manufactured by Merck & Co., Inc. The update noted 28 reported cases
of intussusception identified through the US Vaccine Adverse Event Reporting
System, but clarified that “the number of intussusception cases reported to
date after RotaTeq administration does not exceed expected background rates
among unvaccinated children of the same age.”
its website posted February 14, the US CDC affirmed its continued support
for use of the vaccine: “This notice does not mean there is a problem with the
RotaTeq® vaccine. CDC is not changing its policy at this time. CDC continues
to support the Advisory Committee on Immunization Practices’ [ACIP]
recommendation for routine immunization of all U.S. infants with three doses
of RotaTeq® administered orally at ages 2, 4 and 6 months.” The ACIP will
conduct a regularly-scheduled review of the safety tracking data during its
upcoming meeting on February 21, and the CDC stated that it will continue to
monitor reports of possible adverse effects of the vaccine in partnership with the FDA.
Media reports of the FDA notice implied a link between the vaccine and
intussusception that is not supported by the current data. To avoid further
misperceptions, PATH is reaching out to key audiences, including the
investigators with whom we are collaborating to conduct clinical trials of
RotaTeq® in Africa and Asia, as well as our partners in the global health community.
Innovative investment accelerates global access to pneumococcal vaccines
The governments of Italy, Canada, Russia, the United Kingdom, and Norway;
and the Bill & Melinda Gates Foundation recently announced their decision to
financially support an Advance Market Commitment (AMC) for the purchase of
pneumococcal vaccines for developing countries. Pneumococcus, a bacterium that
is one of the most common causes of pneumonia, kills about one million
children under age five each year. By creating incentives for companies to
invest in vaccines for diseases that disproportionately affect developing
countries, an AMC can help create more predictable markets and accelerate
research and development.

Investigators’ meeting in London kicks off key clinical trials
At an investigators’ meeting in
London last month, PATH and partners met to finalize plans to launch Phase 3
clinical trials of RotaTeq, the rotavirus vaccine manufactured by Merck & Co.,
Inc. PATH and Merck are partnering with leading researchers in Asia and Africa
to conduct efficacy trials in five countries: Bangladesh, Vietnam, Kenya, Ghana,
and Mali. Enrollment at some study sites will be initiated as early as this
month, and results are anticipated by mid-2009. Meeting participants, including
leading rotavirus experts from NIH and WHO, reviewed the study protocol for the
study to ensure adherence, scientific rigor, and regulatory compliance.
Update on rotavirus surveillance
Routine surveillance is revealing
significant rates of rotavirus among children suffering from diarrheal disease
in Pakistan, where two sites recorded rates of 20 and 38 percent, respectively.
The data were generated through hospital-based rotavirus surveillance supported
by the WHO Eastern Mediterranean Regional Office and were presented at the Third
Annual Symposium on Neonatal and Child Health organized by the country’s
National Insititute of Child Health.
Sentinel hospital-based surveillance supported by PATH, CDC, and WHO recently

Vaccination may be factor in reduced seasonal rotavirus incidence in El Salvador
The current rotavirus season in El Salvador is providing insight into the
real-world impact of vaccine introduction as well as the disease’s epidemiology
in the country. Often mislabeled in the local media as a result of “outbreaks,”
cases of rotavirus routinely increase in the region during the winter months due
to natural epidemiological patterns. But vaccination against rotavirus,
initiated in El Salvador last October, is already helping to reduce this burden.
To date, more than 20,000 infants in El Salvador have been fully immunized, and
an impact can be seen in the latest surveillance figures. In January 2006, 164
cases including 15 deaths were confirmed among children between 7 and 14 months
of age. By comparison, 114 rotavirus cases and four deaths were confirmed among
unvaccinated children during the same period this year, and no reports of
rotavirus have been recorded among vaccinated children.
El Salvador is one of several countries in Latin America that report monthly
rotavirus surveillance data to the Pan American Health Organization.

Developing country officials weigh in on GAVI support for rotavirus vaccines
The GAVI Alliance Boards unanimous decision last
month to subsidize funding for rotavirus and pneumococcal vaccines will have
a significant impact on the health of children in developing countries,
beginning as soon as 2008. Officials in these countries shared their
reactions to this landmark advancement:
The Health Ministry of Uzbekistan applauds
GAVIs funding for the vaccines against rotavirus and pneumococcal
diseases. These much needed vaccines will protect our children and allow us
to reduce [our countrys] mortality rate. — Mr. B.I.
Niyazmatov, Deputy Minister of Health, Republic of Uzbekistan
Guyana is determined to introduce these new
vaccines into our routine program, and we are grateful that GAVI has included
the two vaccines for funding. With GAVI's continued support, further inroads
in infant morbidity and mortality can be achieved. Guyana looks forwards to
being a pioneer country in this respect. — Dr. Leslie
Ramsammy, Minister of Health, Guyana

New support from
GAVI enables RVP to gather critical evidence in Africa and Asia
Earlier this year, the GAVI Alliance awarded $15 million
to the Rotavirus Vaccine Program (RVP) to advance the clinical trials agenda
for rotavirus vaccines produced by GlaxoSmithKline (GSK) and Merck & Co,
Inc. Ongoing trials and upcoming studies, conducted in collaboration with GSK
and Merck, will evaluate the vaccines efficacy and safety among
pediatric populations in Africa and Asia and will provide fundamental
information regarding the value of rotavirus vaccines in these settings.
Spotlight on reference centers to support global rotavirus surveillance
The latest issue of Rotavirus Surveillance News,
published by the US CDC, provides an overview of the Rotavirus Collaborating Centers and Reference Centers supported by RVP. These essential resources provide
consultation and training on strain characterization, laboratory diagnostics,
and other standard procedures for scientists conducting active rotavirus
surveillance around the world. To date, laboratory personnel from more than
35 countries have received training and other support from the five centers.
Center directors are also finalizing a unified laboratory manual for use in the field. To learn more,

Enrollment begins in
trial to determine Rotarix® efficacy and safety in Africa
On October 17, 2006, investigators in Malawi initiated enrollment for a clinical trial supported by RVP and GSK to determine the
safety and efficacy of Rotarix®. As part of the same clinical trial,
enrollment in South Africa was reinitiated in November 2006, where more than
1,800 infants have been enrolled to date.
Rotarix® is orally administered and, historically, these
types of vaccines have performed differently in different regions of the
world. Large-scale trials of Rotarix® in North and South America affirmed
their safety and efficacy among these populations. However, the WHOs
Advisory Group of Experts recommended that new rotavirus vaccines should
also be studied among infants in Asia and Africa, where the burden of
rotavirus disease is very high.
Bond sales to accelerate support for new vaccines and system strengthening
The International Finance Facility for Immunisation
(IFFIm) issued its inaugural bonds last month, kicking off an innovative scheme
to accelerate funding for vaccination programs in the worlds poorest
countries. IFFIm is the latest in groundbreaking strategies spearheaded by
the GAVI Alliance to accelerate delivery of lifesaving interventions to
benefit the worlds children. Through this new initiative, immediate
financing for national immunization programs in developing countries will be
raised by selling bonds in the international capital markets, based on
legally-binding long term commitments from donors—including the governments
of Britain, France, Italy, Norway, Spain, and Sweden.

Review of surveillance data in US confirms safety profile of Mercks rotavirus vaccine
During their meeting on October 25 and 26, 2006, the US
Advisory Committee on Immunization Practices reviewed early surveillance data
on the safety of RotaTeq®. As of September 30, 2006, nearly 1.8 million doses
of the vaccine had been distributed, and the estimated incidence of
intussusception (six reported cases total) was lower than the expected
background rate, even after accounting for underreporting. CDC will continue
to collect data on intussusception and other adverse events through its
Vaccine Safety Datalink and Vaccine Adverse Event Reporting System.

Nicaragua demonstration program garners international attention
The landmark collaboration between the
Government of Nicaragua and Merck to provide rotavirus vaccines to children
reached by the public health system was warmly welcomed in international media.
The demonstration program will provide free doses of ROTATEQ®, Merck’s
three-dose oral rotavirus vaccine, to all infants in Nicaragua for the next
As Dr. Julian Lob-Levyt, executive
secretary of the GAVI Alliance, noted, “This demonstration project is a
significant step toward global use of rotavirus vaccines, which have the
potential to save hundreds of thousands of lives and help the world achieve the
Millennium Development Goals. It is also a good illustration of what can be
achieved by combining and integrating political will with private resources and
partner support to deliver the outcomes needed to reach the health MDGs.”
The demonstration project announced by
the Government of Nicaragua and Merck is an important milestone toward
accelerating rotavirus vaccine introduction in GAVI-eligible countries. It will
provide valuable lessons as RVP and partners seek to build awareness and
replicate such progress in the region and throughout the developing world. In
addition to its potential to save thousands of lives, Nicaragua’s experience
will help illuminate the benefits and challenges of integrating rotavirus
vaccines into routine immunization programs in resource-limited settings. Merck donating vaccine against diarrheal illness to Nicaragua for 3 years,

UNICEF cites diarrheal disease control as
key element in reducing mortality
The Lancet recently highlighted
the role of diarrheal disease control as part of an integrated approach to child
survival. Interventions including low-osmolarity oral rehydration solution
(ORS), zinc treatment, and promotion of breastfeeding were among five indicators
used to define a comprehensive child health policy.
The article reviewed the adoption of such interventions by WHO member states
as measures of progress toward achieving Millennium Development Goal #4 (to
reduce mortality of children under five by two-thirds). Investigators found
that, while some countries have successfully implemented the use of low-osmolarity
ORS and zinc treatment, many countries reported low rates of diarrheal disease
management. This finding emphasizes the urgency of disseminating relevant data
among country-level public health officials so that they may make informed
decisions on diarrheal disease control measures, including rotavirus vaccines.
A renewed focus on diarrheal disease
control has emerged as a priority in global public health, and surveys conducted
by RVP among officials and clinicians in developing countries found similar gaps
in awareness and implementation. The development and availability of new
rotavirus vaccines offers an opportunity to invigorate broader diarrheal disease
control efforts. Learn more about what RVP is doing in this arena by visiting
our online Enhanced Diarrheal Disease
Control Resource Center.

Shaping new guidelines for evaluating vaccine cost-effectiveness
Weekly Epidemiologic Record (September 15) featured recommendations on
assessing the cost-effectiveness of rotavirus vaccines. A March 2006 meeting was
convened by WHO, the US CDC, and PATH as a forum for participants to review
country-level data as well as global guidelines and a standard protocol for
future costing studies. These recommendations are an important component of the
evidence that decision-makers will weigh in considering potential rotavirus
In an encouraging twist, the meeting’s recommendations to decision-makers in developing countries are providing
important guidance to the evaluation of vaccine introduction in the
industrialized world. The US Advisory Committee on Immunization Practices (ACIP)
looks to follow the lead of RVP and partners in developing standardized
methodology for measuring the cost-effectiveness of vaccines. According to Dr.
Jean Clare Smith, CDC medical officer and assistant to the director for
immunization policy, “Although the focus of the meeting was international, the
discussions and recommendations parallel work being done at CDC to develop a
standardized approach to economic analyses of vaccines being considered by the
ACIP for introduction in the US.”
Lancet article provides update on current rotavirus vaccines
Our CDC partners continue to strengthen
the evidence base through surveillance of rotavirus morbidity and mortality and
training initiatives. In a recent
Lancet review article (July
22), CDC experts detailed the status of rotavirus vaccines and the urgency to
make them accessible in the developing world. “Rotavirus vaccines: current
prospects and future challenges” provides background on rotavirus disease,
historic milestones in vaccine development, and a summary of the obstacles to
overcome in accelerating their introduction.

Co-awardees included Dr. Richard A. Cash and Dr. Dilip Mahalanabis
(Award for Public Health) and Dr. Stanley Schultz (Award for Medicine). His Majesty King Bhumibol Adulyadej graciously granted permission for
the establishment of the “Prince Mahidol Award” in commemoration of
the centenary of the Birthday Anniversary of His Royal Highness Prince
Mahidol of Songkla on January 1st, 1992. The Award is administered by
the Prince Mahidol Award Foundation under the Royal Patronage of which
Her Royal Highness Princess Maha Chakri Sirindhorn is the President.
The Foundation confers two international awards each year—one for the
exemplary contributions in the field of medicine and the other in the
field of public health.
| In 2006, there are a total of 59 nominations from 29 countries around
the world. The Scientific Advisory Committee carefully screened and
submitted the short list to the International Award Committee who
scrutinized and made a recommendation for the Award laureates to the
Board of Trustees. H.R.H. Princess Maha Chakri Sirindhorn presided
over the meeting of the Board of Trustees in which the final decision
on the Award laureates was made. On November 1st, 2006, the Board of Trustees made a unanimous decision
to confer the Prince Mahidol Award for 2006 to a group of medical
professionals who, during the 1960s and the 1970s, had dedicated their
lives to the discovery, the introduction, and the widespread use of
“Oral Rehydration Solution (ORS) or Oral Rehydration Therapy (ORT).”
This simple, inexpensive, but effective treatment of severe diarrhea
can be practiced by patients and their household members themselves.
The treatment has been used worldwide, both in the developed and in
the developing countries alike. It is estimated that the introduction
of the ORT has saved more than 40 million lives in the past 30 years. The discovery and introduction of Oral Rehydration Therapy is a major
achievement in the human health service by applying “appropriate
technology” based on scientifically-proven clinical research. The
Lancet, a very prestigious medical journal, has recognized the ORT as
“the most important medical discovery of the 20th century”. Four of the most distinguished scholars and scientists are conferred
the Prince Mahidol Awards for 2006: In the Field of Medicine:
Professor Stanley G. Schultz, MD. is the former Dean of the
University of Texas Medical School at Houston in Texas, USA. He is
now Professor of the Department of Integrative Biology Pharmacology,
University of Texas Medical School at Houston, Texas, U.S.A. In the
1960s, Dr. Schultz and his team demonstrated that glucose and sodium
absorption in the small intestine was intimately coupled, and glucose
could facilitate the absorption of sodium and water. This pioneering work provided the scientific foundation for the use of
the oral rehydration solution consisting of salt, sugar and water in
the treatment of dehydration in diarrhea patients. Since the early
1970s, the ORT has continuously benefited the lives of millions of
children each year all over the world. Dr. Schultz is also known to be
a great teacher, receiving several teaching awards including Teacher
of the Year award from the American Physiological Society. In the Field of Public Health:
David R. Nalin, MD. Is the former Director of Vaccine
Scientific Affairs. Merck Vaccine Division, Merck&Co. Inc., West
Point, Pennsylvania, U.S.A. Dr. David R. Nalin, was assigned, in the
1960s, to the Pakistan-SEATO Cholera Research Laboratory (CRL) in
Dhaka, East Pakistan (presently, the capital city of Bangladesh) as a
research associate at the US National Institutes of Health (NIH). Dr
Nalin, Dr Richard Cash, and their colleagues successfully tested the
efficacy of an oral glucose-electrolyte solution, later known as oral
rehydration therapy (ORT), to be used instead of intravenous fluid for
the treatment of patients with severe cholera. This new treatment was tested in Matlab and then used by the Johns
Hopkins University International Center for Medical Research and
Training (ICMRT) in Calcutta in the refugee camps during the
Liberation War of Bangladesh in 1971. Later as a WHO consultant, Dr
Nalin has helped establish a number of highly successful national
programs on the oral rehydration therapy for diarrhea diseases in
Costa Rica, Jamaica, Jordan, and Pakistan. Richard A. Cash, MD, MPH. is Senior Lecturer on International
Health at the Department of Population and International Health,
Harvard University School of Public Health, Boston, U.S.A. As a young clinician, right after finishing his internship in New York
City, working at the Pakistan-SEATO Cholera Research Laboratory (CRL)
in Dhaka in 1960s, Dr Cash had been involved in the first
scientifically-proven successful clinical trial of testing the oral
rehydration therapy on severe diarrhea patients. The trial has become
a landmark for subsequently applying this treatment around the world. Dilip Mahalanabis, MD. is the Director of the Society for
Applied Studies, a non-governmental research organization, in Kolkata, India. Dr. Dilip Mahalanabis started his work on oral rehydration therapy in
1966 as a research investigator for Johns Hopkins University
International Center for Medical Research and Training in Calcutta.
During the Liberation War of Bangladesh in 1971, Dr. Mahalanabis used
the ORT in the refugee camps which accommodated 350,000 refugees, in West Bengal. Dr. Dilip Mahalanabis instructed his staff to distribute the ORT for
the treatment of over 3,000 patients. With the ORT, the death rate
dropped to only 3% in comparison with 20 – 30% using only intravenous
fluid therapy. This was the first large – scale use of oral
rehydration solution in a disaster situation. As a result, it gained
the International health Organizations’ recognition and its
application was spread worldwide. The research works conducted by Dr. David R. Nalin, Dr. Richard A.
Cash, and Dr. Dilip Mahalanabis have sequentially contributed to the
application of the oral rehydration solution in the treatment of
severe diarrhea worldwide, including Thailand. It is estimated that
each year around 500 million packs of the oral rehydration solution is
used in more than 60 developing countries, saving millions of lives
around the world. Supat Vanichakarn MD., Worawut Smuthkalin, Ph.D.

Indian scientists develop anti-diarrhoea vaccine
Indo-Asian News Service - New Delhi
November 5, 2004 The first Indian vaccine to prevent a virulent form of diarrhoea that kills
hundreds of children every year is ready for clinical trial. Developed over 10 years by researchers at the All India Institute of Medical
Sciences here and the Indian Institute of Science in Bangalore, the vaccine,
isolated from the bodies of newborn babies, has passed laboratory tests and will now be tested on humans. "If all goes well, the vaccine will be available in the markets in two to
three years," M.K. Bhan, secretary of the Department of Science and Technology, told IANS.
Diarrhoea vaccine 'a step closer'
Children in the developing world are particularly vulnerable
26 August, 2004
Scientists have discovered how the virus that causes most cases of diarrhoea invades cells. The Boston Children's Medical School team say the finding could help develop an vaccine to combat the rotavirus. The virus, the most common cause of severe, dehydrating diarrhoea, kills around 440,000 children a year, mainly in developing countries. Writing in Nature, the researchers say understanding more about the virus will help them fight it successfully. The researchers say their work shows how vaccine development can be made "smarter" by looking at the physical make-up of viruses and finding the minimum parts needed to prime the immune system, without having to use a whole virus to make a vaccine. Almost all children are infected with the rotavirus as toddlers. It can cause gastroenteritis that is sometimes severe enough to require hospital care. Breaking into cells Scientists have been working to develop a vaccine which will be effective against the virus for some time. Two vaccine have been licensed. One was used in the US, but was withdrawn after it was linked to a condition which causes bowel obstruction. The second has only been licensed for use in China. The researchers in this study examined the geometric structure and behaviour of one of the rotavirus's surface proteins, called VP4, which plays a key role in binding on to the surface of a target cell, and breaking through its membrane. The key finding for vaccine development is that the "head" and "body" portions of the VP4 protein contain many of the targets that the immune system recognises when it attacks the virus and protects against infection, they say. "The work is a clear example of the way in which structural studies can contribute to new good ideas about strategies for vaccines," said Dr Stephen Harrison, head of the Children's Medical Hospital Laboratory of Molecular Medicine.
Meeting the MDG Drinking Water and Sanitation Target:
A mid-term assessment of progress
26 August, 2004
In adopting the Millennium Development Goals that address the most pressing development issues, countries pledged to halve the proportion of people without access to safe drinking water and basic sanitation. Yet, more than 1 billion people today
lack safe drinking water, and some 2.6 billion - half of the developing world - lack improved sanitation. This publication reports on our progress towards the MDG goal of ensuring environmental sustainability. It seeks to encourage countries slow
to meet the target to accelerate action, and highlights areas where efforts need to be strengthened in order to meet the goal. UN Water Report

Handwashing Program Dramatically Cuts Childhood Diarrhea in Pakistan
1 June, 2004 A household handwashing program in Pakistan substantially reduced the occurrence of diarrhea among children living in a high-risk situation, according to a report in this week's Journal of the American Medical Association. The results come from a study of more than 4500 children living in 36 low-income neighborhoods in Karachi. In 25 of the neighborhoods, handwashing was promoted to encourage the use of plain or antibacterial soap after defecation, food preparation, eating, and child feeding. The other 11 neighborhoods served as the control group. In their report, Dr. Stephen P. Luby, from the Centers for Disease Control and Prevention in Atlanta, and colleagues write: "In these communities in which diarrhea is the leading cause of childhood death, wash water was heavily contaminated with human fecal organisms, and no provisions were made for clean drying of hands, handwashing promotion with soap halved the burden of diarrheal disease." Compared with children from control neighborhoods, those from a neighborhood encouraging plain soap use had a 53 percent lower rate of diarrhea. In addition, the plain soap intervention was tied to a 39 percent reduction in the number of days with diarrhea. No apparent advantage was seen for using antibacterial soap rather than plain soap, since the antibacterial agent has no effect on many organisms that cause diarrhea. "Although visiting households weekly to provide free soap and encourage handwashing was effective in reducing diarrhea, this approach is prohibitively expensive for widespread implementation," the authors point out. Therefore, less costly approaches are needed to reach the millions of children living in at-risk households. SOURCE: Journal of the American Medical Association.
The Rotavirus Vaccine Program
Evan Simpson, Program for Appropriate Technology in Health (PATH),
[email protected] PATH's Rotavirus Vaccine Program was created in 2003 to reduce child morbidity and mortality from childhood
diarrhoeal disease by accelerating the availability of rotavirus vaccines appropriate for use in developing countries. Strategies include:
- Vaccine demand: providing potential vaccine purchasers at global, national, and local levels with information about disease burden estimates, safety and efficacy; financing and economic data; and immunisation policy analysis.
- Vaccine supply: collecting data needed to conduct demand forecasts and market surveys, and information related to international supply requirements. "The aim is to overcome demand uncertainty, which has been a significant barrier to ensuring vaccine availability in developing countries."
NIH Attempts To Revive Diarrhea Vaccine
5 May, 2004
Washington (AP) -- The National Institutes of Health is attempting to revive an anti-diarrhea vaccine that was pulled off the market five years ago after a life-threatening side effect struck some babies. At issue is rotavirus, an intestinal infection that kills 600,000 children worldwide each year. In the United States, 3 million children get rotavirus annually, but good medical care ensures only about 40 of them die. In developing countries, however, about one child in every 250 dies of rotavirus. more info

Child survival: a global health challenge - A series of papers - THE LANCET
26 July, 2003
Where and why are 10 million children dying every year?
How many child deaths can we prevent this year?
Reducing child mortality: can public health deliver?
Applying an equity lens to child health and mortality: more of the same is not enough
The series of papers on child survival that have appeared in The Lancet
describes a major public health challenge: more than 10 million children dying each
year because they have not been reached by known and effective interventions.1 Children are dying because of the
neglect of common and preventable childhood illnesses, of health problems in newborn babies, and of the measures
needed to protect mothers and infants during pregnancy and childbirth. The child survival series was written by technical experts who recognised a set of problems, reviewed the evidence,
and challenged WHO, UNICEF, other UN agencies, multilateral and bilateral agencies, non-governmental
organisations, and health professionals to take appropriate action. Now it is time for policy makers and public-health
leaders to respond, and to transform this knowledge into action. Three commitments must be pursued urgently and unremittingly. Where and why are 10 million children dying every year?
The first paper in this series on child survival
presented an unacceptable picture: more than 10 million children dying every
year, almost all in low-income countries or poor areas of middle-income
countries. 90% of these deaths occurred in just 42 countries, most from one of a
short list of causes: diarrhoea, pneumonia, measles, malaria, HIV/AIDS, and the
underlying cause of undernutrition for deaths among children younger than 5
years, and asphyxia, preterm delivery, sepsis, and tetanus for deaths among
neonates. The assessment of deaths by cause provides a useful starting point for
a stocktaking of available child survival interventions. http://www.thelancet.com/
Rotavirus Vaccines, Take Two 19 August, 2002
Renewed immunization efforts look to avoid pitfalls of failed predecessor | By Bob Beale
excerpts The optimism however, has reemerged with new vaccines that are in the pipeline. And perhaps within the next five years, the battle against rotavirus can be rejoined. Although public awareness is low, rotavirus is one of the world's worst infectious disease agents, killing up to 2,000 children a day. "We now have the potential for several other vaccines becoming available in developing nations, made by national producers in China, India, and Indonesia, and by multinational producers within the next three to five years. As a result, we may even achieve our goals faster than we would have before with just one product and one company." The Scientist | Volume 16 | Issue 16 | 34
New Rehydration Formula to Save Millions of Lives 10 May, 2002 The World Health Organization, released a new improved formula of Oral Rehydration Salts (ORS) on Wednesday that would save millions of lives and reduce the severity of illness of those suffering from acute diarrhoea, WHO reported. ORS is a sodium and glucose solution used to treat children with
acute diarrhoea. WHO said the new formula would reduce the severity of diarrhoea and vomiting, the number of
hospitalisations, the need for costly intravenous fluid treatment and the length of illness. Use of the new ORS formula would begin later this year in India, WHO said. more info

Maryland Rice-Based ORS Product
Clinically Superior to Glucose-Based Oral Rehydration Salts
July 2001 STUDY IN SWEDISH PEDIATRIC JOURNAL ACTA PAEDIATRICA Cost effective - decreased doses compared to World Health Organization ORS A study of 167 boys with cholera compared the safety and efficacy of CeraLyte, a rice-based oral rehydration solution (ORS) to the standard "World Health Organization formula" glucose ORS, concluding that the
CeraLyte ORS, as in other studies with long-chain rice carbohydrate, is more
effective than glucose ORS. The boys, ages 5 to 15 years, suffered severe
dehydrating diarrhea, with losses equivalent to about 30% of their body weight while hospitalized. On average, these boys were admitted 14 hours
after their illness began, by which time they had already lost 14% of their
body weight to dehydration. Thus, total average volume lost during illness was about 44%. - more info
New Oral Rehydration Solution More Effective for Children with Diarrhea;
2 April, 2001 WHO Plans to Make Changes Based on New Research Findings Multicenter, Randomized, Double-Blind Clinical Trial to Evaluate the Efficacy and Safety of a Reduced Osmolarity Oral Rehydration Salts Solution in Children With Acute Watery Diarrhea Children who receive a less concentrated (reduced osmolarity) oral rehydration solution for the treatment of dehydration and diarrhea are
significantly less likely to need costly intravenous (IV) fluid treatment
compared to children treated with the current solution used by the World
Health Organization (WHO), according to a new study conducted by the Johns
Hopkins School of Public Health and five other institutions around the world. Based on the latest research findings, the WHO plans to conduct a
meeting of experts to revise its recommendations on oral rehydration solution formulation for treatment of children with diarrhea. The study is
published in April 2001 edition of Pediatrics. "More than 200,000 children are hospitalized and nearly 300 die from severe
diarrhea in the U.S. each year and the problem is worse in other countries.
The reduced osmolarity, or less concentrated, oral rehydration solution is
a very effective treatment and it will be extremely beneficial to children
in developing countries who might not have access to IV's and advanced medical care," says co-author Mathuram
Santosham, MD, MPH, professor of international health at the Johns Hopkins School of Public Health. Since its development in the 1960s, oral rehydration solution has been credited with saving the lives of millions of children throughout the world
who suffer from dehydration caused by severe diarrhea. The solution is a
mixture of water, glucose, sodium, potassium, and electrolytes, which help
children recover and retain vital fluids and nutrients. The United Nations
Children's Fund (UNICEF) distributes oral rehydration solution worldwide.
Similar solutions are sold in U.S. supermarkets under different brand names
such as Pedialyte and Infanlyte. The new reduced osmolarity solution is a less concentrated formula and contains less sodium than the current WHO solution. The lower osmolarity
helps the body absorb water more quickly and reduces the risk of
hypernatraemia, which is a rare but deadly disorder caused by too much salt
in the body. For the double-blind study, researchers randomly selected 675 children from
health centers in five developing countries who suffered from diarrhea. All
of the children selected for the study were between one and 24 months of
age. Half of the group was treated with the current rehydration solution
while the other half was treated with the new reduced osmolarity solution. "We found that the children who received the reduced osmolarity solution
were 33 percent less likely to need IV treatment when compared to the children treated with the current WHO formula. Also, the new formula was equally effective at reducing diarrhea and vomiting," explains Dr.
The study was funded by grants from the World Health Organization (WHO),
Division of Child Health and Development, Applied Research on Child Health
Project of the Harvard Institute for International Development, and the United Nations Children's Fund (UNICEF).
WHO: Soda Bottles, Sunlight Can Save Millions Of Lives A Year 21 March, 2001 GENEVA (AP) - A do-it-yourself technique of disinfecting water with sunlight and soft-drink bottles could save up to 2.5 million lives a year, the World Health Organization said Thursday. In a campaign to reduce water-related deaths in developing countries, the United Nations health agency is promoting Solar Water Disinfection or SODIS. Martin Wegelin, a researcher at the Swiss Institute for Environmental Science and Technology, said when transparent bottles are filled with water and placed horizontally on a flat surface for about five hours, the heat and ultraviolet rays of the sun kill illness-causing microorganisms in polluted water. The method is even more effective when the bottom half of the bottle is painted black or placed on black-painted corrugated iron or plastic sheets, he said. More than one billion people drink unsafe water, WHO said in a report on water and sanitation released to mark World Water Day. Some 3.4
billion people, mostly children, die every year from water-related diseases, which include malaria, diarrhea and guinea worm. WHO urged the use of SODIS, chlorination and better hygiene as immediate means of improving people's water supply in developing countries. Chlorination is another simple method that costs just a few cents a day, WHO said. "Even in conditions of very poor sanitation and hygiene, where people are collecting whatever water is available for their household supply, if the water is chlorinated (it) is improved," said Mark
Sobsey, professor of environmental microbiology at the University of North Carolina in Chapel Hill. "And you can find statistically significant decreases in diarrhea disease." WHO said chlorine could be added to both home and city reservoirs and was essential in refugee camps. The International Federation of the Red Cross and Red Crescent said it was redoubling its efforts to provide disaster victims with access to clean water and sanitation. It has been deploying emergency water purification units to relief camps and provides 20 million liters (5.3 million gallons) of water per day to one million people, spending 50 million Swiss francs dlrs 30 million) a year.

Synthetic Vaccine Against Infant Diarrhoea for Angola
22 February, 2001
Panafrican News Agency (Dakar)
Luanda, Angola A synthetic vaccine against infant diarrhoea will be tested in Angola this week, US scientist John Robbins announced during a visit to the
Americo Boa Vida hospital in Luanda. Robbins, accompanied by his colleague Rachel Schnerson, has been in Angola since 18 February at the invitation of the health ministry, to
study the causes of diarrhoea among Angolan children. While the test results are awaited, there are negotiations between the inventors of the vaccine (Robbins and Schnerson) and Angolan
specialists in paediatrics since the product essentially concerns children. The American researchers, whose visit will end Saturday, will publish other discoveries, particularly those regarding infections in children, in
order to national hospitals to detect the microbes that cause some of those diseases. Robbins explained that his team had developed a product called "Aemofilos
tipo-B", which effectively fights bacterial meningitis in
children and has been found very useful in many countries, notably in the US. He also announced the manufacture of other medicines against convulsive cough, as well as the conclusion of a study on the fight
against typhoid fever. He said the eradication of typhoid fever was 92 percent efficient. Robbins is current head of the Molecular Development and Immunity Department at the US-based National Institute of Health.
Poorer Half Of The World Can Expect Better Health And Prosperity In The Next Decade
2 January, 2001
Washington A new report jointly issued today by five United Nations agencies and the World Bank claims that
worsening AIDS, TB and malaria epidemics are not inevitable and shows numerous strategies
deployed by several developing countries to successfully fight these diseases, and prevent the deaths they cause. The targets for reducing the toll of these illnesses, set by the world's leaders at successive
summits over the last year, remain feasible. What is needed are the funds and systems that will
enable widespread implementation of actions that have shown to be effective, the report says. The report contains success stories from 20 different countries, encompassing the widest variety
of economic, social and geographic conditions. It shows, for example, how countries like Senegal,
Uganda and Thailand have developed strategies that successfully can reduce HIV infection rates,
how Azerbaijan and Vietnam have cut in half the number of deaths from malaria, how China, India and Peru have cut TB deaths by half, and how Sri Lanka
has drastically reduced maternal mortality. The report Health, a key to Prosperity: Success Stories in Developing Countries the World Health
Organization (WHO), the United Nations Children's Fund (UNICEF), the United Nations
Educational, Scientific and Cultural Organization (UNESCO), the Joint United Nations Program on
HIV/AIDS (UNAIDS), the United Nations Population Fund (UNFPA) and the World Bank outline key
factors for combating AIDS, tuberculosis, malaria, childhood diseases and maternal and prenatal
conditions, even in resource-poor settings. more

FOR IMMEDIATE RELEASE
Researchers at the Johns Hopkins School of Public Health have found that zinc supplements help children suffering from acute and persistent
diarrhea significantly reduce the duration of their symptoms. The study can be
found in the December 2000 issue of the American Journal of Clinical Nutrition. "Diarrhea is a very serious public health problem in developing countries, resulting in millions of deaths each year. Those who survive are often
left with malnutrition. This study was important because it measures the effect
of supplemental zinc given in conjunction with oral rehydration therapy during the recovery from acute or persistent diarrhea," said study
co-coordinator Robert Black, MD, MPH, professor and chair, International Health, Johns Hopkins School of Public Health. The researchers analyzed ten randomized, controlled studies that had assessed the therapeutic benefit of zinc supplements in children under age
five. In the case of the acute-diarrhea trials, diarrhea was defined as three or four loose stools in a 24-hour period. For persistent diarrhea,
the original trials' definitions for diarrhea and recovery were retained. All trials used the standard World Health Organization recommendations for
fluid and dietary case management of diarrhea. The researchers divided the participants of all the reviewed studies into subgroups according to sex,
age, weight-for-height, and initial plasma zinc concentration, and then evaluated the overall effect of zinc on each group. Results of the study showed that the children who were given a zinc supplement during the acute-diarrhea trials were 15 percent less likely
than controls to still have diarrhea by a given day; children in the persistent-diarrhea trials had a 24 percent lower risk of the diarrhea
continuing. The authors said their meta-analysis showed that zinc apparently offers comparable benefits to all subgroups, a finding that
indicates the nutrient needn't be aimed only at certain narrow populations but is feasible for wide use in the developing world. Although future studies are still needed to examine the effect of zinc supplementation on other measures of severity, such as diarrheal output,
occurrence of dehydration, treatment failure, or death, the researchers believe attention should now focus on the best means of providing zinc
during diarrhea, as well as on other ways to increase the zinc intake of children in developing countries. This study was supported by the Johns Hopkins Family Health and Child Survival Cooperative Agreement with the U.S. Agency for International
Development, by the World Health Organization's Division of Child Health and Development, and by the Rockefeller Foundation's Bellagio Study and

El Nino Increases Diarrheal Disease Incidence By 200 Percent 4 February, 2000
BALTIMORE (Johns Hopkins) — The El Nino phenomenon, the warming of the equatorial Pacific ocean that occurs every two to seven
years, has been linked to outbreaks of dengue, malaria and cholera. Now, researchers from the Johns Hopkins School of
Public Health, A.B. Prisma, and the Instituto Nacional de Salud in Lima, Peru, have found that the 1997-1998 El Niño season
increased hospitalizations for diarrheal disease by 200 percent. Click here for a PowerPoint slide show on Effects

Withdraws Rotavirus Vaccine From Market 18 October, 1999 WESTPORT, (Reuters Health) - The Wyeth Lederle Vaccines unit of American Home
Products said on Friday that it has voluntarily withdrawn its RotaShield rotavirus vaccine
from the market and has requested an immediate return of all vaccine doses. The
withdrawal follows a temporary suspension of distribution and administration of the
vaccine that was announced on July 16. As Reuters Health reported at the time, the
US Centers for Disease Control and Prevention requested that healthcare providers and
parents postpone use of RotaShield in infants until November, following reports of
intussusception in some infants who received the vaccine.
Rotavirus Vaccine May Be Linked To More Cases Of Bowel Disorder
Bethesda, MD (Reuters Health) The Food and Drug Administration (FDA) has received
reports of 99 cases of intussusception that may be related to Wyeth-Ayerst's RotaShield
rotavirus vaccine, an FDA medical officer said Tuesday. The number is a huge jump from the previously noted 15 cases, reported as of July 7.

CDC: Cease Use Of Diarrhea Vaccine 16 July, 1999
ATLANTA (AP), The government is recommending that doctors
temporarily stop giving children a diarrhea vaccine because at least 20 infants have
developed a bowel obstruction after getting their shot.
First Do No Harm:
Making Oral Rehydration Solution (ORS) Safer In A Cholera Epidemic
Oral rehydration solution (ORS) is lifesaving therapy for cholera and
pediatric diarrhea. During a cholera epidemic in Guinea-Bissau, we evaluated the
microbiologic quality of ORS prepared at a hospital and tested a simple intervention using
special vessels for disinfecting tap water with bleach and for preparing, storing, and
dispensing ORS. Few coliform bacteria and Escherichia coli were recovered from tap water; however,
pre-intervention ORS contained numerous bacteria including E. coli and toxigenic Vibrio
cholerae O1. In contrast, ORS samples from intervention vessels had few or no coliform
bacteria, no E. coli, and no V. cholerae. Mean pre-intervention counts of
coliform bacteria (3.4 × 107
colony-forming units [cfu]/100 ml) and E. coli (6.2 × 103
cfu) decreased significantly during the intervention period to 3.6 × 102 cfu and 0
cfu, respectively (P < 0.001). This simple system using bleach disinfectant and special storage vessels prevents
bacterial contamination of ORS and reduces the risk of nosocomial transmission of cholera
and other enteric pathogens.
