Bangladesh Measles Outbreak: Emergency Vaccinations Launched as Child Deaths Rise

Bangladesh has initiated an emergency vaccination campaign to combat a severe measles outbreak that has resulted in the deaths of more than 100 children in less than a month. The government, in coordination with international health organizations, is working to close critical immunity gaps that have allowed the highly contagious airborne disease to spread rapidly across the country.

The emergency drive, which launched on April 5, 2026, targets more than a million children. The campaign is being conducted in partnership with the United Nations, the World Health Organization (WHO), UNICEF, and the Gavi vaccine alliance to deploy measles-rubella vaccines already available within the country.

Scale of the Outbreak and Response

Official data indicates that more than 900 cases of measles have been confirmed since March 15, 2026, out of approximately 7,500 suspected cases reported. This surge is described as the worst the South Asian nation has experienced in years.

The vaccination strategy is being rolled out in phases. The initial stage focuses on children between the ages of 6 months and 5 years old across 18 high-risk districts. Following this initial phase, the government plans to expand the campaign nationwide starting in May 2026.

Public health officials emphasize that the current situation is particularly dangerous for the youngest infants. Rana Flowers, the UNICEF representative in Bangladesh, noted that infections among infants under nine months are especially alarming because these children are not yet eligible for routine vaccination.

Causes of the Resurgence

The resurgence of measles in Bangladesh is attributed to significant gaps in vaccination coverage. The newly elected government stated that mismanagement by previous administrations led to shortages in vaccine stockpiles and program gaps in vulnerable regions.

The WHO and UN highlight that achieving a 95% vaccination rate across the population is necessary to establish herd immunity and stop the transmission of the disease. The current outbreak underscores the risks posed by zero-dose and under-vaccinated children who lack the necessary immunity to resist the virus.

Medical Context of Measles

Measles is an airborne infectious disease characterized by fever, respiratory symptoms, and a distinct rash. While it is preventable through vaccination, it can lead to severe or fatal complications, particularly in young children.

The situation in Bangladesh reflects a broader global trend of declining vaccination rates. In 2024, more than 11 million cases of measles were recorded globally. Other regions have also seen spikes, including the United States, which registered more than 2,000 cases in 2025, marking its worst spread in three decades. The United Kingdom also experienced a fatal outbreak this year that resulted in two deaths.

The loss of children’s lives in this outbreak is a tragic reminder that measles can quickly turn deadly when immunity gaps persist.

Gavi

The current emergency response aims to stabilize the child death toll and prevent further spread by rapidly increasing the proportion of the population that is immunized, focusing specifically on the most vulnerable age groups and high-risk districts.
