Bangladesh’s Measles Crisis Exposes How Fast Vaccine Gains Can Collapse

A preventable disease returns with deadly force

Bangladesh is facing its worst measles outbreak in years, with more than 120,000 suspected and confirmed cases reported since the surge began in mid March 2026. Government figures cited in recent reports include nearly 750 suspected or confirmed deaths, most of them children. Other health authority updates recorded lower totals at earlier points in the outbreak, reflecting the difficulty of testing and counting cases during a fast moving national emergency.

The outbreak has spread across most of the country’s districts and placed hospitals under severe pressure. At Medical College Hospital in Mymensingh, nearly 130 measles patients were being treated in 32 rooms, more than twice the ward’s intended capacity. Families have been forced to sleep on blankets in corridors and on floors while doctors care for children suffering from pneumonia, heart failure and severe breathing problems.

“I have never seen an outbreak this huge,” paediatrician Dr Mohammed Golam Mawla said while describing the situation in Mymensingh. The scale of the crisis is striking because Bangladesh had previously made strong progress against measles. Vaccination coverage had remained above 90 percent for years, and the country had been moving toward the goal of eliminating the disease.

Measles spreads through the air when an infected person coughs, sneezes or breathes. It is among the most contagious human diseases. A child who is unvaccinated can become infected after brief contact with someone carrying the virus, especially in crowded homes, schools, clinics and public transport.

How did vaccination gaps build up?

Measles protection depends on sustained coverage, rather than a single emergency campaign. Bangladesh routinely gives measles and rubella vaccine doses at about nine months and 15 months of age. It also uses wider campaigns every few years to reach children who missed routine vaccination.

Data from Bangladesh’s 2023 Coverage Evaluation Survey showed that first dose coverage had fallen from 88.6 percent in 2019 to 86 percent. Second dose coverage dropped from 89 percent to 80.7 percent. That left millions of children without full protection. The country remained below the estimated 95 percent two dose coverage needed to stop sustained transmission.

The COVID pandemic disrupted routine immunisation around the world. In Bangladesh, measles vaccination coverage fell by about 51 percent during April and May 2020. The country then missed or delayed follow up campaigns that could have reached children left unprotected. A supplementary campaign expected in 2024 or 2025 was also delayed as political turmoil disrupted government services.

In practical terms, each missed campaign added another group of susceptible children. The number of unprotected children grew quietly until the virus found enough people to spread rapidly. Children under five account for about four in five cases in the current outbreak. Infants under nine months have faced particular danger because many are too young for the first routine dose.

Nutrition has also shaped the severity of the outbreak. Measles can weaken the immune system and make children more vulnerable to pneumonia, diarrhoea and other infections. Malnutrition and vitamin A deficiency can make those complications more severe. Health researchers have reported high levels of stunting and wasting among young children in Bangladesh, increasing the risk that an infection will become fatal.

Why did vaccine procurement become a political issue?

The vaccine gap was linked to a breakdown in procurement after the political upheaval that removed former Prime Minister Sheikh Hasina in 2024. During the interim administration led by Muhammad Yunus, officials considered changing how vaccines were purchased. The government moved toward a competitive tender system while also considering new suppliers and different financing arrangements.

UNICEF had traditionally helped supply vaccines through a direct procurement system supported by international partners, including Gavi, the Vaccine Alliance. UNICEF warned that changing the arrangement could create delays and stock shortages. The tender process became caught in administrative delays, and reports later described stockouts of several vaccine types at the central depot in Dhaka, including measles and rubella vaccine.

Officials from the former interim administration have disputed claims that they caused a vaccine shortage. Syedur Rahman, who held a senior health role during that period, said the government had continued to work with UNICEF and that communications about procurement did not contain a specific warning of an imminent measles outbreak. He argued that competitive purchasing was intended to improve transparency and control costs.

The new government under Prime Minister Tarique Rahman has said it found shortages and serious gaps when it took office in February. Health Minister Sardar Sakhawat Hossain has acknowledged that political disruption affected vaccination work. The government has said the procurement decisions will be examined.

The dispute has become a question of accountability, yet the public health lesson is broader. Vaccine systems depend on reliable purchasing, timely financing, cold storage, trained staff, accurate records and regular contact with families. A failure in one part can leave children unprotected even when vaccines are free and clinics exist.

What is happening inside hospitals?

Hospitals across Bangladesh have struggled to absorb the number of sick children. In Dhaka, all 120 beds set aside for measles patients at Bangladesh Shishu Hospital were reported to be occupied during the height of the outbreak. Rural families have travelled many hours to reach facilities with oxygen, intensive care and specialist doctors.

Four month old Arafat was taken to Mymensingh after his parents travelled for almost 10 hours. Doctors diagnosed pneumonia and heart failure, both recognised complications of measles. Oxygen tubes were too large for his small nose, so staff secured them with tape and bandages. His father, Mohammad Alam Mia, borrowed money from neighbours to pay for care. Arafat later died.

In another case, Mosammat Nila Akhter and her husband took their 10 month old daughter Maliha to a clinic in February, where they were told that no vaccine was available. Maliha was later admitted with pneumonia. When a rash appeared, her parents struggled to find a hospital bed. They waited at one facility, then travelled by ambulance to another while their daughter found it increasingly difficult to breathe. Doctors said she needed intensive care, but the first hospital had no bed. Maliha died three days later.

“Who to blame?” Akhter asked after losing her child. “Should I blame the government because my child did not get the vaccine?”

Such cases show why hospital treatment alone cannot stop measles deaths. By the time a seriously ill child reaches a major city hospital, pneumonia, dehydration or low oxygen levels may already be advanced. Care at community clinics, local hospitals and district facilities can help identify danger signs earlier and reduce the number of children arriving in critical condition.

How large is the outbreak?

Reported totals have changed quickly as more districts have begun reporting and as suspected cases have been added to laboratory confirmed infections. Between 15 March and 14 April, national health authorities recorded 19,161 suspected cases and 2,897 laboratory confirmed cases across 91 percent of districts, along with 166 suspected deaths. By early May, suspected cases had reached about 55,000 and deaths had passed 400.

Later reports recorded more than 59,000 suspected cases and 401 suspected deaths, while confirmed infections exceeded 8,000. Bangladesh health authorities subsequently reported more than 116,000 suspected cases and 780 combined confirmed and suspected deaths at one stage. The original government figures cited in the current account place the suspected and confirmed case total above 120,000 and the death toll near 750.

These figures are not directly interchangeable. A suspected case may never receive laboratory confirmation, while some children die before testing is possible. UNICEF has warned that the true death toll may be higher because health facilities are overwhelmed and reporting is uneven. The differing counts all point to the same fact: transmission has been widespread and children have continued to die from a disease that vaccination can prevent.

The outbreak was reported in 58 of the country’s 64 districts at an earlier stage. Genetic analysis found continuing transmission, suggesting that the virus was spreading within communities rather than appearing as a brief cluster. Authorities have also reported concern about spread near the border with Myanmar, where conflict has disrupted health services.

Has the emergency campaign slowed transmission?

The government, UNICEF and other health partners began an emergency measles and rubella campaign in April. It first targeted high risk areas and children between six months and five years, then expanded nationwide from 20 April. The campaign offered protection to some infants younger than the normal routine vaccination age because of the exceptional danger created by the outbreak.

Authorities set a target of about 18 million to 20 million children. By early May, more than 18 million had received at least one dose. Local health authorities later reported that about 18.5 million children had been vaccinated, exceeding the stated target. The World Health Organization classified the outbreak as a Grade 2 emergency, a designation used for a moderate scale event requiring coordinated support from several agencies.

Reported cases and deaths have begun to slow in areas with stronger vaccination coverage. Health officials say the emergency response has helped, although the country has still been recording hundreds of suspected cases each day and repeated deaths. A campaign can reduce transmission, yet it cannot instantly restore protection for every child who missed earlier doses.

Public health expert Mohammad Mushtuq Husain has said the country must vaccinate children who missed either dose, including those older than five. He has also called for treatment to be strengthened at community clinics, subdistrict hospitals and district facilities rather than relying on large hospitals in Dhaka and other major cities.

Digital tracking could help locate children who have received no vaccines at all, often called zero dose children. Better use of Bangladesh’s VaxEPI immunisation platform, door to door outreach and direct communication with parents could help find families who do not attend fixed vaccination sites.

A second outbreak is adding pressure

Bangladesh’s health system is also facing a growing dengue outbreak. Dengue cases rose from 714 between January and the end of May to more than 7,100 by early July, with 19 reported deaths. The rainy season creates breeding grounds for Aedes mosquitoes, which spread dengue, while crowded indoor conditions can help measles spread through the air.

The two diseases can produce fever and rash, creating a risk of misdiagnosis. Dengue and measles require different forms of care, so accurate testing and clinical assessment are essential. Hospitals treating measles patients have had to reserve beds and staff while dengue admissions rise. Doctors are also dealing with malnutrition, pneumonia and other infections among children whose immune systems have been weakened.

The overlapping outbreaks show the need for strong disease surveillance and enough hospital capacity before a crisis begins. Testing shortages make it harder to distinguish illnesses, measure transmission and direct health workers to the communities at greatest risk.

What must happen after the emergency?

Bangladesh has a long record of successful immunisation. Its Expanded Programme on Immunisation, launched in 1979, helped raise childhood vaccination coverage from about 2 percent in the 1980s to roughly 90 percent in recent years. The country also demonstrated that large measles and rubella campaigns can reach millions of children.

The current crisis shows that those gains require steady management. Authorities will need to restore routine vaccine supplies, complete missed doses, rebuild regular supplementary campaigns and protect funding from political disruption. They will also need reliable information about which children have been vaccinated, because reported coverage may not match actual immunity in every community.

Urban areas deserve particular attention. Second dose coverage in urban Bangladesh was estimated at about 75 percent in 2023, below the reported rural level. Families living in informal settlements may face overcrowded clinics, irregular work, transport costs and limited access to health information. Vaccine services must reach those communities through schools, mobile teams and local outreach.

Trust is another part of the response. Some families remain uncertain about vaccines because of misinformation, cultural concerns or fears about religious conflicts. Health workers who can answer questions in familiar language are more effective than general announcements alone. Clear public information should explain when children need routine doses, where vaccines are available and what symptoms require urgent medical care.

UNICEF spokesperson Miguel Mateos Muñoz described the situation as a “perfect storm” involving procurement delays, pandemic disruption, the absence of regular mass campaigns, overcrowding and travel during Eid. He also warned that reported numbers should be treated cautiously because the available data may not capture every case.

“What it’s telling us is that the work is still not done,” Muñoz said.

For families such as Arafat’s and Maliha’s, the crisis is measured in hospital corridors, borrowed money and children who never came home. Bangladesh’s measles outbreak is a warning that progress against infectious disease can weaken quietly when routine services are interrupted. Emergency vaccination has begun to slow the surge, yet lasting protection will depend on restoring the everyday systems that keep children vaccinated before the next outbreak starts.

The Bottom Line

• Bangladesh has reported more than 120,000 suspected and confirmed measles cases since mid March 2026.
• Reported deaths range across official updates, with nearly 750 suspected or confirmed deaths cited in the latest account.
• Vaccination coverage fell after pandemic disruption, procurement delays and missed mass campaigns.
• Children under five make up most cases, while infants face severe risk from pneumonia and other complications.
• An emergency campaign has vaccinated more than 18 million children across the country.
• Routine vaccination, community treatment, accurate records and public trust are needed to prevent another surge.
