Measles Outbreak in Bangladesh Kills Dozens of Children as Vaccination Gaps Widen

What Is Happening With the Measles Outbreak in Bangladesh?

Bangladesh is currently battling one of its worst measles outbreaks in recent years. According to a report published by The BMJ, at least 38 children have died, with cases concentrated in areas with low immunization coverage. The outbreak has overwhelmed local health facilities and prompted emergency vaccination campaigns targeting vulnerable communities.

Measles is one of the most contagious infectious diseases known, spreading through respiratory droplets with a reproduction number (R0) of 12 to 18 — meaning one infected person can transmit the virus to 12 to 18 others in a susceptible population. While a safe and effective vaccine has been available for decades, even small dips in coverage can trigger explosive outbreaks. The WHO recommends that at least 95% of the population receive two doses of measles-containing vaccine to maintain herd immunity and prevent sustained transmission.

Why Are Measles Cases Surging Globally?

The Bangladesh outbreak is part of a broader global trend. WHO and UNICEF have reported that the COVID-19 pandemic caused historic disruptions to childhood immunization programs worldwide. According to WHO data, approximately 33 million children missed measles vaccine doses in 2023 alone — roughly 22 million missing their first dose and 11 million missing their second. These immunity gaps have allowed measles to resurge in countries across Africa, Southeast Asia, and Europe.

Beyond pandemic disruptions, vaccine hesitancy, conflict, displacement, and weakened health systems have compounded the problem. WHO declared measles an "imminent global threat" and has called for urgent investment in catch-up vaccination campaigns. The organization emphasizes that measles is entirely preventable and that every child death from the disease represents a failure of public health systems to deliver a proven, low-cost intervention.

How Can Measles Outbreaks Be Prevented?

The measles vaccine is one of the most successful public health tools ever developed. Two doses of measles-containing vaccine provide approximately 97% protection against infection. WHO's recommended schedule calls for the first dose at 9 to 12 months of age and the second dose at 15 to 18 months, though schedules may vary by country. Catch-up campaigns targeting older unvaccinated children are critical during outbreaks.

Public health experts stress the importance of strengthening routine immunization infrastructure, particularly in low- and middle-income countries where coverage gaps are most pronounced. Surveillance systems that can rapidly detect and respond to outbreaks are equally important. The Bangladesh outbreak serves as a stark reminder that without sustained commitment to vaccination programs, diseases once on the path to elimination can return with devastating consequences for the most vulnerable populations — young children.
