Tue Nov 19 16:56:07 UTC 2024: ## Bangladesh’s Robust Immunization Program Limits Disease Outbreak After Devastating Floods

**DHAKA, BANGLADESH** – Despite record-breaking monsoon floods that submerged large parts of Bangladesh between June and September, a major infectious disease outbreak was averted thanks to the country’s high vaccination rates. The flooding, described as the worst in 34 years in some areas, left 1.2 million families trapped and at high risk of waterborne illnesses.

While tens of thousands of cases of diarrhoea and skin disease were reported, along with nearly 5,000 respiratory infections, and 127 deaths from various causes, the scale of the health crisis was significantly less than anticipated. Experts attribute this largely to Bangladesh’s impressive immunization coverage. Data from the World Health Organization and UNICEF shows 98% of children have received their third dose of the diphtheria, tetanus, and pertussis vaccine, while measles and pneumonia vaccination rates are also exceptionally high.

“Usually, pneumonia and measles outbreaks occur in flood-hit areas,” explained Dr. Tajul Islam A Bari, an immunization expert. “This year, that didn’t happen.” This sentiment was echoed by Dr. Ahammed Kabir, Civil Surgeon of Lakshmipur district, who noted that while diarrhoea cases increased, no widespread epidemic occurred. Sheikh Daud Adnan, Line Director (CDC) of the Directorate General of Health Services (DGHS), attributed this largely to routine immunisation and the provision of medical services during the floods.

While the DGHS acknowledges challenges in providing services during the disaster, including difficulties reaching remote areas, health workers established temporary health camps in shelters and conducted follow-up vaccination campaigns once the waters receded. This ensured children who missed their scheduled vaccinations due to the floods received the necessary doses.

Mohammad Shamsuddoh, a climate expert, emphasized that the intensity and duration of monsoon rainfall in Bangladesh are increasing, highlighting the need for a robust and adaptable healthcare system capable of responding to increasingly frequent and severe climate-related disasters. The success in mitigating a widespread disease outbreak demonstrates the vital role of a strong immunization program in protecting vulnerable populations during natural disasters.
