23 SEP 2026 — Bangladesh recorded 132 measles cases in the whole of 2025, and nobody died. By eight o'clock on the morning of 20 September this year, the national health directorate had counted 179,814 suspected cases and 1,057 deaths.
That gap contains the largest measles vaccination drive the country has ever run.
What the numbers now say
The Directorate General of Health Services publishes a running count. To the morning of 20 September it recorded 101 laboratory-confirmed deaths and 956 more among patients with measles symptoms, a combined 1,057. Confirmed cases stood at 20,562 and suspected cases at 179,814.
In the preceding twenty-four hours, four children died, 88 new confirmed cases were recorded and 1,148 new suspected ones. Since 15 March, 158,589 people have been admitted to hospital with measles symptoms, and 152,225 have recovered.
The outbreak began in late February. It was declared nationwide on 4 April.
A record campaign that missed
The emergency measles-rubella campaign launched on 20 April, aimed at 18 million children between six months and five years old. By mid-September about 19.75 million doses had been administered.
More doses were given than the target called for, yet the outbreak did not stop.
The denominator problem
The explanation may be arithmetic, not logistics. Mushtuq Hussain, formerly principal scientific officer at the Institute of Epidemiology, Disease Control and Research, told Al Jazeera that the population estimates used to set the campaign target understated how many eligible children there actually were.
A separate vitamin A campaign in late June reached roughly 24 million children across a similar age band, suggesting the true number is higher. If a figure near 24 million is closer to the truth, then 18 million was never going to be full coverage, and 19.75 million doses is not the comfortable margin it looks like.
Who is dying
At the Infectious Diseases Hospital in Dhaka, 57 measles deaths had been recorded by 23 August. Forty-nine of them, about 86 per cent, were children under fifteen months. Thirty-one were infants under nine months, which is younger than the age at which routine measles vaccination begins.
Forty-seven of the 57, or 83 per cent, were unvaccinated. Pneumonia was recorded in 50.
Infants below nine months cannot be protected by their own vaccination, because they have not reached the age for it. They are protected only by everyone around them being immune. That is who the failure lands on first, and it is who a coverage figure never describes.
Coverage was slipping before this
Coverage was already slipping. The 2023 Coverage Evaluation Survey put first-dose measles-rubella coverage at 86 per cent, down from 88.6 per cent in 2019. Second-dose coverage had fallen further, from 89 per cent to 80.7 per cent.
The World Health Organization's threshold for interrupting transmission is 95 per cent for both doses. Bangladesh was below it on the first dose and well below on the second before a single case of this outbreak was counted. Pandemic disruption, procurement delays and shortages ran through 2024 and 2025.
Those shortfalls are enough to explain an outbreak of this size. What it needed was for someone to count the children, not the doses.
