Since mid-March 2026, measles has killed more than 528 children in Bangladesh and generated over 60,000 suspected cases — a crisis driven by a collapse in vaccination coverage that has received a fraction of the international attention given to other concurrent outbreaks.
“We’ve been crying out loud about this from the beginning, but it has been a silent situation,” says Hasina Rahman, a health official tracking the crisis. “There hasn’t been much attention around it.”
She is describing a measles outbreak in Bangladesh that, by the time it attracted international notice, had already taken more than 500 children’s lives. Since the virus took off in mid-March, the country has tallied more than 60,000 suspected cases and 528 suspected measles-related deaths. The dead are mostly children under five. The disease is vaccine-preventable. And yet it has killed at a rate, and in numbers, that mark this as the deadliest measles surge in Bangladesh in decades.
While Ebola and hantavirus have dominated global public health coverage in May 2026, this crisis — unfolding in the densely populated megacity of Dhaka and spreading across 58 of Bangladesh’s 64 districts — has received minimal international coverage until now.
The Scale of the Crisis
A measles outbreak in Bangladesh has killed more than 500 children in the deadliest surge there in decades. The death toll continued to rise, with 13 children passing away in a single 24-hour period, increasing the total to 512 according to a health department tally that began on March 15.
Local news outlets in Bangladesh have been announcing daily death counts — sometimes in the single digits but often higher. On one day — May 4 — 17 children died. The number of new suspected cases most days has topped 1,000 and on some days is over 1,500.
Half of all deaths — both suspected and confirmed — have been recorded in Dhaka division, followed by Rajshahi, according to government data compiled by the Directorate General of Health Services. Officials attribute the capital’s disproportionate toll partly to referral patterns, as critically ill patients are routinely transferred from district and upazila-level hospitals to Dhaka’s overstretched facilities.
Hospitals in the capital Dhaka, which have been overwhelmed with cases, have set up dedicated wards but lack sufficient numbers of intensive care beds.
How Did This Happen?
Bangladesh has not always struggled with measles. Over the decade to 2015, the country made genuine progress in measles control, with nationwide vaccination campaigns reaching over 50 million children and first-dose coverage exceeding 92%. That record makes the 2026 crisis more, not less, alarming — because it shows how quickly immunisation gains can be reversed when political commitment and funding falter.
Almost 5 million children in Bangladesh were not fully immunised in 2025, including 70,000 children with zero doses and more than 400,000 children who were underimmunised.
Bangladesh has not conducted a nationwide measles-rubella campaign since 2020, and shortages in vaccine supply and field-level health workers have left many children unprotected.
Measles is one of the most contagious diseases known to medicine. A single infected person can transmit the virus to between 12 and 18 unvaccinated individuals. When vaccination coverage falls below the 95% threshold required for herd immunity — the level at which enough people are immune to prevent the virus from finding new hosts — an outbreak is not a question of if, but when.
In Dhaka, cases are concentrated in densely populated informal settlements, including Demra, Jatrabari, Kamrangirchar, Korail, Mirpur, and Tejgaon industrial and slum clusters. These are precisely the communities where vaccination campaigns are hardest to reach and where children are most likely to be malnourished — a factor that significantly worsens measles outcomes.
Why Children Are Dying, Not Just Getting Sick
Measles is often described in public discourse as a mild childhood disease. In a well-nourished child with good healthcare access, the immediate illness is manageable, and complications — while possible — are not inevitable. In a malnourished child with limited healthcare access, measles is a different disease.
The disease primarily affects children and can cause severe complications, including pneumonia, brain inflammation and death, particularly among malnourished or unvaccinated children. Most cases recorded during the outbreak have been among children aged between six months and five years.
Doctors say many of the children arriving at hospitals were already critically ill. “Though measles is highly contagious, a healthy baby with no complications can survive with minimal medication,” said Ainul Islam Khan, a paediatrician at Dhaka’s Shaheed Suhrawardy Medical College and Hospital. “Here, most children came to the hospital with respiratory distress and infections in the eyes, throat and lungs.”
The Infectious Diseases Hospital in Mohakhali, Dhaka, admitted 560 suspected measles cases in the first three months of 2026 compared with 69 suspected cases for the entire year before. March alone accounted for 448 of those admissions. The crude in-hospital mortality rate reached 3.9% overall and 4.7% for March admissions — an alarming statistic for a vaccine-preventable disease.
The Lancet, in an analysis published in April, described this as not merely an increase in case counts but “a severity crisis” — with hospitals managing a “rare burden of hypoxic, malnourished, and acutely ill children.”
The Emergency Response
The Bangladeshi government acknowledged the crisis on April 4 and launched an emergency vaccination programme on April 5, beginning in 30 high-burden areas before expanding to four city corporations and eventually the entire country.
As of May 4, the campaign had reached 16.1 million children, or 89 percent of its 18 million target.
UNICEF, WHO, and Gavi — the Vaccine Alliance — are supporting the rollout of outbreak response immunisation, initially prioritising children in densely populated and high-risk areas, with a nationwide measles-rubella follow-up campaign targeting 20 million children aged 6 months to 59 months.
Health experts cautioned, however, that immunity takes three to four weeks to develop after vaccination, meaning a meaningful decline in deaths and new cases is not expected before late May or early June.
There are tentative signs that the campaign is beginning to work. The government has stated the outbreak is now contained in several previously hard-hit areas, and the daily case counts, while still elevated, have shown some reduction from their peak. But with children still dying daily and vaccination immunity still building, the crisis is not over.
The Accountability Question
The International Society for Human Rights has expressed profound concern over the outbreak, describing it as having exposed “deep vulnerabilities within the national public health system” and emphasising that “the primary responsibility rests with the state.”
That framing — responsibility resting with the state — points to a broader question about how Bangladesh allowed its vaccination infrastructure to deteriorate so severely. The 2020 nationwide campaign was the last of its kind. In the years since, coverage has fallen, monitoring has weakened, and the signal that millions of children were unvaccinated was not acted upon before the outbreak began.
The human cost of that gap is now measurable in hundreds of children’s lives.
What Happens Next
The vaccination campaign underway will build population immunity over the coming weeks and should bring the outbreak under control by early June if coverage targets are met and maintained. The government and international partners are working to ensure the current campaign is followed by a comprehensive strengthening of routine immunisation infrastructure — the kind of sustained investment that prevents outbreaks from starting, rather than responding after they have already caused mass casualties.
For the children who died between March and May 2026, that investment came too late. For the millions of children under five in Bangladesh, it is the difference between another outbreak and a return to the measles-controlled trajectory the country had achieved a decade ago.
Measles is preventable. Its resurgence anywhere in the world is a systems failure — of funding, of monitoring, of political will, and of the international attention that holds governments accountable for the health of their most vulnerable citizens.
