Looking back through the pages of history, when Bangladesh emerged on the global stage in 1971 after a bloody war of independence, prominent global economists looked at the new nation with deep skepticism. Some even famously ridiculed it as a “bottomless basket.” Yet, through the passage of time, Bangladesh is no longer a name associated with neglect; rather, it stands as a radiant beacon on the map of global public health. The driving force behind this magnificent transformation is an institution that has spent the last six decades working silently, away from the spotlight, in the service of humanity—the ‘icddr,b’ or the ‘International Centre for Diarrhoeal Disease Research, Bangladesh’. From combating deadly cholera epidemics to discovering life-saving formulas like ORS, down to the recent global threat of the COVID-19 pandemic—this institution has consistently emerged as a savior during every major health crisis. icddr,b is not merely a crown jewel of Bangladesh’s national pride; it is an inseparable, historic chapter in the legacy of global medical science.
Historical Background and Establishment: The Journey of a Lifetime
The roots of icddr,b run deeper than the history of independent Bangladesh itself. Around the middle of the twentieth century, particularly during the 1950s, cholera was a terrifying harbinger of death across Asia. The relentless onslaught of diarrhoea and cholera wiped out entire villages. With no definitive or affordable treatment available, people were left to surrender their fates to the disease.
SEATO Cholera Research Laboratory (CRL): To halt this humanitarian disaster, the Cholera Research Laboratory (CRL) was established in Dhaka in 1960 under the auspices of the South-East Asia Treaty Organization (SEATO). Its core objective was to carry out intensive research on the cholera bacterium and discover definitive measures to contain its outbreaks.
The Light of Independence and Autonomy: Following Bangladesh’s liberation in 1971, the significance and operational scope of this laboratory expanded exponentially. Its role became indispensable to safeguarding the health of citizens in a newly born country. Consequently, in 1978, through a special presidential ordinance issued by the Government of Bangladesh, CRL was transformed into a fully autonomous international institution. Thus, the ‘International Centre for Diarrhoeal Disease Research, Bangladesh’ (icddr,b) was born.
Today, that modest laboratory in Mohakhali has evolved into one of the world’s premier health research institutions, where local and international researchers work shoulder-to-shoulder, driven by the shared mission of serving humanity through the light of science.
ORS and the Magic of Saline: A Revolutionary Discovery
If there is one milestone for which icddr,b’s name will forever be written in letters of gold in the annals of history, it is the development of ORS (Oral Rehydration Salts)—popularly known as khabar saline (oral saline).
The Crucible of History: The Liberation War of 1971 was not just a battle for a sovereign territory; it was a desperate struggle for sheer survival. When millions of Bangladeshis took refuge in neighboring India, cholera and diarrhoea broke out in epidemic proportions across the refugee camps. At that critical juncture, the precise formulation of glucose and salt developed by icddr,b researchers was taken straight out of the laboratory and deployed into the field. The result was pure magic—millions of lives were pulled back from the brink of certain death.
Subsequently, the World Health Organization (WHO) formally recognized icddr,b’s formulation, hailing it as “potentially the most important medical advance this century.” This simple, highly affordable mixture of a pinch of salt, a fistful of molasses or sugar, and half a liter of water has saved hundreds of millions of children globally over the last few decades. Later, the institution’s scientists developed a ‘rice-based ORS’ by substituting sugar with rice powder, which proved even faster and more effective in treating diarrhoeal dehydration.
The Matlab Surveillance System: A Treasure Trove of Global Public Health Data
The absolute cornerstone of icddr,b’s research triumphs is the ‘Health and Demographic Surveillance System’ (HDSS) located in the Matlab sub-district of Chandpur. Initiated in 1966, this field-based operational initiative is revered globally as the longest-running and most meticulous demographic database in medical history.
Researchers have maintained a close watch over a population of approximately 250,000 people spanning several generations in Matlab. They meticulously analyze the dynamics of births, deaths, diseases, maternal and child health, family planning, and nutrition within a typical rural community. The invaluable insights gathered here form the very foundation upon which international bodies like the World Health Organization and UNICEF design their global health policies and immunization frameworks.
Multifaceted Contributions to Public Health and Medicine
With the passage of time, icddr,b has continuously evolved. It has refused to limit its focus merely to the treatment of diarrhoea or cholera, choosing instead to shine its scientific light into virtually every corner of public health.
National Immunization Programs (EPI) and Vaccines: Bangladesh’s massive success in keeping its remote rural children safe from debilitating diseases like polio, measles, rubella, and tetanus owes a massive debt to the government’s Expanded Programme on Immunization (EPI). Behind the scenes, icddr,b acted as the scientific and technical backbone of this program. Furthermore, the institution’s pioneering role in assessing the real-world efficacy of vaccines for Rotavirus, Cholera, and the Human Papillomavirus (HPV) for cervical cancer prevention remains undeniable.
The War Against Severe Malnutrition: To eradicate childhood malnutrition in Bangladesh, the institution developed therapeutic nutritious foods using easily accessible local ingredients like rice, lentils, peanuts, and milk powder. These therapeutic food models heal malnourished children much faster than synthetic medicines and have earned widespread international acclaim.
Unmasking Infectious Diseases and Viruses: Alongside its work on Tuberculosis, HIV, and Dengue, icddr,b played a crucial role when the ‘Nipah virus’ emerged as a terrifying winter threat in Bangladesh. It was icddr,b scientists who first uncovered the groundbreaking truth that this fatal virus was jumping from fruit bats to humans through the consumption of raw date palm sap.
Non-communicable Diseases and Climate Impacts: Driven by changing modern lifestyles, non-communicable diseases such as diabetes, cancer, and cardiovascular ailments have risen sharply, prompting the institution to launch extensive research programs in these areas. Concurrently, their recent studies have highlighted the profound consequences of climate change—revealing how rising sea levels increase salinity in the drinking water of coastal regions, significantly elevating the risk of gestational hypertension (preeclampsia) and miscarriage among pregnant women.
Urban Public Health and the Protection of Slum Dwellers
A major segment of icddr,b’s modern research addresses urban health, specifically focusing on the livelihoods of the floating populations and slum dwellers of Dhaka city. The health vulnerabilities in these densely packed urban slums are entirely distinct from those in rural areas.
Safe Water and Sanitation: The acute shortage of safe drinking water and abysmal sanitation facilities in Dhaka’s slums trigger constant outbreaks of waterborne pathogens. In response, icddr,b introduced affordable water filters and implemented community-based sanitation models across these settlements, resulting in a dramatic drop in local diarrhoeal rates.
Healthcare for Marginalized Urban Communities: To ensure healthcare reaches the most destitute urban citizens, the institution has routinely deployed mobile clinics and satellite centers. These efforts have kept vital public health indicators stable despite the intense pressures of rapid, unplanned urbanization.
Antimicrobial Resistance: Researching an Invisible Catastrophe
The medical community currently faces one of its greatest existential threats: ‘Antimicrobial Resistance’ (AMR), where common medicines lose their power against evolving pathogens. Due to the widespread, unregulated, and incorrect dosage of antibiotics, ordinary bacteria are rapidly transforming into formidable ‘superbugs.’ icddr,b stands at the very frontlines of this global crisis.
Surveillance and Laboratory Networks: The institution consistently gathers bacterial samples from various hospitals across Bangladesh to systematically monitor which life-saving drugs are losing their efficacy. This crucial data aids the World Health Organization in formulating global early-warning networks.
Awareness and Policy Advocacy: icddr,b works closely with government policymakers to implement strict regulations against over-the-counter antibiotic sales without medical prescriptions, while simultaneously educating the public on responsible antibiotic usage.
The COVID-19 Pandemic and Frontline Battles
When an invisible, unfamiliar virus ground the entire world to a halt in 2020, crippling the health infrastructures of even the most developed nations, icddr,b stood as a pillar of resilience and hope for Bangladesh.
At the very dawn of the pandemic, the institution rapidly set up state-of-the-art RT-PCR testing laboratories to serve the public. Beyond testing, they performed continuous genome sequencing to identify which specific viral variants (such as Delta and Omicron) were circulating in Bangladesh, providing the government with critical data to make informed policy decisions. Additionally, the institution served as a frontline warrior by executing international clinical trials for vaccines and establishing optimal treatment and oxygen-therapy protocols for hospitalized patients.
Climate Change and the New Equation of Public Health
Bangladesh remains one of the most vulnerable countries globally to the impacts of climate change. The visionary scientists at icddr,b recognized early on that changes in the environment bear a profound, direct relationship with human physiological health.
The Coastal Crisis and Pregnant Mothers: As sea levels rise, the salinity of groundwater in the southern coastal belt of Bangladesh has scaled alarming heights. Research conducted by icddr,b revealed a devastating correlation: the consumption of this highly saline water leads to a multifold increase in preeclampsia (severe high blood pressure) and premature miscarriages among pregnant women. This stark discovery has completely reframed global discussions on the human cost of climate change.
Temperature Swings and Disease Vectors: The institution works tirelessly to decode how global warming alters the behavior and breeding patterns of disease vectors like mosquitoes, which drives the rapid spread of illnesses like Dengue and Chikungunya into entirely new territories.
International Recognition and Humanity’s Badges of Honor
Through its unparalleled dedication to human welfare and public health advancements, icddr,b has accumulated a stellar array of international accolades.
Gates Global Health Award (2001): Bestowed by the Bill & Melinda Gates Foundation, this highly prestigious award recognized the institution’s monumental contribution to inventing ORS and controlling diarrhoeal illnesses. Notably, icddr,b was the first institution in the world to receive this honor.
