Bangladesh measles outbreak death toll surpasses 650 children as WHO and UNICEF rush emergency vaccination support to curb regional spread
Bangladesh’s measles outbreak, which began in mid-March 2026, has killed at least 652 children, health officials said, making it the country’s deadliest in decades. The World Health Organization and UNICEF have launched emergency vaccination campaigns targeting children aged 6 to 59 months to curb the spread of the highly contagious disease.
Earlier DGHS data cited by the Center for Infectious Disease Research and Policy (CIDRAP) indicated 70,936 suspected cases and 585 deaths since mid-March, with 9,049 lab-confirmed infections and 90 confirmed fatalities. United Nations situation reports from May 5 noted 42,979 suspected cases, 5,729 lab-confirmed cases, and at least 263 suspected and 54 confirmed deaths, acknowledging that mortality is likely underreported due to diagnostic constraints and incomplete reporting, especially in remote areas.
According to the Directorate General of Health Services (DGHS), the outbreak began in mid-March 2026 and has since resulted in at least 652 child deaths, including 560 with measles-like symptoms and 92 laboratory-confirmed cases, as reported by Prothom Alo on May 12.
Health officials have identified children under five as the most affected group, with a particular concentration among those aged 6 to 59 months. Early outbreak data reported by Al Jazeera showed 6,476 suspected cases and 826 confirmed pediatric cases in that age range during the initial weeks, with 16 confirmed deaths. The outbreak has been concentrated in densely populated urban and peri-urban districts, with the government designating approximately 30 worst-affected areas for priority vaccination. DGHS figures shared with CIDRAP revealed that 56,886 patients required hospitalization, placing significant strain on pediatric and infectious disease services; of those hospitalized, 93%—or 52,841 patients—had been discharged as recovered. UN reports described the outbreak as intensifying pressure on the health system, particularly in facilities serving vulnerable and hard-to-reach populations.
In response, Bangladesh’s government launched a nationwide emergency mass vaccination campaign on April 5, 2026, targeting children aged 6 to 59 months. The campaign aimed to vaccinate between 18 and 20 million children, according to government statements and NPR reporting. UNICEF’s country representative, Rana Flowers, told Al Jazeera that the campaign had successfully reached 18 million children within roughly the first month, with ongoing efforts to identify and immunize those missed initially. NPR coverage confirmed that officials had met their initial vaccination target and were now focusing on locating unvaccinated children. CIDRAP reported that while the campaign intended to administer two doses of measles-containing vaccine for durable immunity, most children had received only the first dose to date, leaving a gap in full protection.
WHO and UNICEF have provided emergency support since early April, including vaccine supplies, cold-chain logistics, and technical guidance for the campaign’s rollout. WHO’s disease outbreak guidance for measles emphasizes rapid response teams, intensive surveillance in border areas, and maintaining at least 95% coverage with two doses of measles vaccine. It also recommends post-exposure prophylaxis for health workers and other high-risk groups and ensuring sufficient stocks of measles-rubella (MR) or measles-mumps-rubella (MMR) vaccines and injection supplies. UNICEF representatives confirmed that emergency measles-rubella vaccination was conducted in high-risk settings, such as camps for displaced populations.
Bangladesh’s health minister announced the cancellation of Eid holidays for medical staff treating measles patients and confirmed the ongoing nationwide vaccination drive to curb the outbreak. DGHS briefings reported by Prothom Alo detailed the increasing death toll and the government’s intensified response. UN situation reports emphasized that the official death figures likely underestimate the true mortality burden due to underreporting and diagnostic limitations.
Health authorities and international agencies have expressed concern about the risk of regional spread, given the high transmissibility of measles and the large number of suspected cases. WHO guidance stresses strengthening epidemiological surveillance in high-traffic border areas and among mobile populations to detect and contain cross-border transmission. UN reports describe the outbreak as a public health emergency with regional implications, noting that under-vaccinated communities and displacement in border districts increase the risk of exported cases. International media have highlighted the crisis’s potential to fuel renewed measles transmission in South Asia, calling attention to low global awareness. WHO recommends ensuring vaccination access for international travelers, transport workers, and displaced populations along travel and migration corridors.
Officials and experts attribute the outbreak to immunity gaps created by disruptions in routine immunization services, including those caused by the COVID-19 pandemic, and pockets of low measles vaccine coverage. Overcrowding, poverty, and malnutrition in some communities have also increased children’s vulnerability to severe disease and complications, contributing to the high death toll, according to UN and media analyses. WHO advises sustaining at least 95% two-dose measles vaccine coverage nationwide after the emergency phase, combined with strengthened case-based surveillance and rapid response teams, to prevent measles from becoming endemic again. Health officials and international partners emphasize that continued emergency vaccination, enhanced surveillance, and targeted outreach to hard-to-reach and border populations will be necessary to reduce mortality, close immunity gaps, and mitigate the risk of ongoing regional spread.
