Bangladesh Measles Outbreak Kills 1,147, Mostly Toddlers

Of the 1,147 people who died in Bangladesh’s measles outbreak, 94 per cent were children under five. The World Health Organisation’s figure sits at the heart of the world’s worst measles outbreak: 202,000 suspected cases reported from mid-March through October 9, including 22,000 laboratory-confirmed cases. No other country reported more suspected cases that year.

A Vaccination System That Slipped

The numbers point to a routine immunisation programme that faltered in 2025. Bangladesh had come close to the 95 per cent coverage the WHO says is needed to prevent outbreaks. It didn’t last. A WHO and UNICEF report published in July estimated first-dose coverage in 2025 at 90 per cent and second-dose coverage at 86 per cent, several percentage points below the herd-immunity threshold.

The same report raised a harder question: could officials trust their own data? It questioned vaccination figures for measles and other diseases from 2023 to 2025. Preliminary numbers sometimes showed more people vaccinated than the number targeted, suggesting errors in dose counts or target figures.

A Reuters review of WHO documents and interviews with more than a dozen scientists, health workers and officials found that emergency preparations were hampered by data that left out millions of children. The review also identified shortcomings in preparation and a failure to reach enough parents. Experts said weak data, inadequate outreach and vaccination gaps slowed the response.

Who Paid the Price

Behind the statistics are families in some of the country’s hardest-hit areas. In the northeastern Sylhet region, two-year-old Arman Hossain died unvaccinated in July, 24 hours after he entered hospital. His family sold their three-wheeled auto rickshaw to pay for his treatment. His unvaccinated four-year-old sister survived.

His father, Amin Mia, 26, said health workers never reached their remote village in time to offer vaccinations. “They came only after I buried my son,” he said.

In Chhatak, also in Sylhet, nine-month-old Labiba Akter died unvaccinated in June. Her father, Humayun Rashid, a 30-year-old carpenter, said she could have received a vaccination in April, when an emergency programme lowered the vaccination age from nine months to six. “No health worker came to tell us,” he said.

Measles usually kills two or three people in every 1,000 cases, the WHO says. It can kill more people in poorer nations because of factors including malnutrition. On September 12, parents kept vigil in an overcrowded measles isolation ward at Sylhet’s Shahid Shamsuddin Ahmed Hospital. Among them was Mohammad Nasir Ali, 40, stroking the forehead of his seven-year-old son, Adil Ahmed. Eight-year-old Masum was also receiving treatment there after developing symptoms.

Official Response

Ziauddin Hyder, special assistant on health affairs to Prime Minister Tarique Rahman, told Reuters in September that the government was doing everything it could to end the outbreak. The government didn’t respond to further questions sent in October.

Mark Jit, a WHO vaccine adviser and professor at the School of Global Public Health at New York University, described the outbreak as a lesson for countries beyond Bangladesh. “This is a real warning to every country,” he said. Preventing an outbreak through vaccination was easier, cheaper and safer than responding to an emergency. “The response will stop the outbreak eventually, but in the meantime, many will have had measles, and some will have died.”

Why This Matters:

The Bangladesh outbreak shows what happens when a public health system’s basics erode: reliable data, reach into remote communities, and steady funding for routine immunisation. The burden fell hardest on infants and toddlers, and on families like the Mias and Rashids, who lived far from clinics and learned too late that protection existed. Arman Hossain’s family sold their livelihood to pay for care that came too late. Jit’s warning applies well beyond one country. Prevention costs less than crisis response, but only if governments keep coverage above the 95 per cent threshold and maintain data they can trust. When they don’t, children pay first.
