OBJECTIVES: Acute watery diarrhea (AWD) remains prevalent (16/1000 population) in Bangladesh. Nationwide AWD surveillance has been active since 2014 across 16 sentinel sites. With an estimated >100,000 cases and approximately 3,500 deaths annually, cholera remains a critical public health concern. This study analyzed AWD surveillance data from June 2022 to September 2024.
METHODS: Suspected cholera cases (rapid diagnostic test [RDT]-positive and culture/polymerase chain reaction [PCR]-positive for cholera) were identified using the United States Centers for Disease Control and Prevention (CDC) clinical definitions, RDTs, and microbiological culture. Socio-demographic, clinical, and etiological characteristics were examined descriptively. Cases identified using the Cholkit RDT.
RESULTS: Among 977 cases, 49 (5%) were RDT-positive for cholera. Culture was not conducted in 41/49 (84%) cases. Children aged <5 years were predominantly affected (56.1%). Two culture-positive cases were RDT-negative. Suspected case surges occurred in November and January. All cases reported drinking untreated water and not using soap after defecation; 67.45% consumed roadside food. Alarmingly, 90% (881/977) of suspected cases had taken antibiotics before hospital admission. The Cumilla Adarsha Sadar sub-district bore the highest burden (66.8% of suspected cases). RDT-positive cases showed variation across demographic and clinical characteristics.
CONCLUSION: The study indicates a substantial burden of AWD, with a small proportion of cases testing RDT-positive for cholera. Enhancing diagnostic capacity particularly microbiological culture use is essential for accurate detection. Public health efforts must prioritize promotion of safe water and handwashing practices.
