Measles surges in Bangladesh, U.S. deaths reported

What's happened

Bangladesh has recorded hundreds of suspected measles deaths and more than 187,000 infections since March while vaccinating roughly 19–20 million children; officials say pockets of unvaccinated children and past procurement delays left gaps. In the U.S., Pennsylvania has confirmed four measles-linked deaths and nearly 700 cases this year as vaccination rates have fallen.

What's behind the headline?

What is driving the outbreaks

• Bangladesh has experienced a rapid rise in cases because routine vaccination coverage fell in 2024–25, procurement changes delayed supplies and the country accumulated large cohorts of susceptible children. Emergency campaigns have vaccinated millions but official figures show gaps of several million children remain.

• In the U.S., measles has returned because coverage has dropped below the ~95% threshold. Pennsylvania’s outbreak is concentrated in specific communities and has produced the state’s first measles deaths in 35 years.

Why current responses are insufficient

• Mass campaigns will not immediately stop transmission. Vaccination campaigns take time to find and reach missed children; chains of transmission that began weeks or months ago will continue to produce cases and severe complications while teams catch up.

• Health systems are already overstretched. Bangladeshi hospitals are operating above capacity and treating dengue at the same time, which will reduce capacity for measles care and increase fatality risk among malnourished children.

Likely next steps and consequences

• Bangladesh will increase door-to-door and intensified search strategies and will continue vaccinating through September and beyond; this will reduce future cases but will not erase deaths already incurrent in transmission chains.

• Pennsylvania and other U.S. jurisdictions will expand MMR access and public messaging; political disputes over vaccine policy and federal reporting will complicate national accounting of measles deaths and slow coherent federal action.

What to watch

• Whether Bangladesh’s intensified campaign announced for late September reaches the estimated 4 million children who were missed; failure to close that gap will sustain high transmission.

• Whether international authorities in November conclude that the U.S. has lost measles-free status; that decision will change global monitoring and funding priorities.

Bottom line

Large immunity gaps created by disrupted routine programmes and local vaccine refusal are producing preventable deaths. Vaccination campaigns will reduce future cases, but the outbreaks will continue until coverage reaches the levels that interrupt transmission.

How we got here

Measles outbreaks have emerged where routine immunisation dropped. Bangladesh has reported large case numbers after political turmoil and pandemic disruptions reduced coverage; an emergency campaign began in April. The U.S. eliminated measles in 2000 but falling vaccination rates and local refusal have produced renewed outbreaks, including a large Pennsylvania cluster.

Our analysis

BBC Business has emphasised scale and logistics, reporting that Bangladesh has vaccinated more than 19.8 million children while still recording about 1,000 suspected deaths and roughly 194,000 cases since March; it quoted UNICEF warning that an "intensified phase" will start on 26 September and WHO saying some target children were not reached. Al Jazeera and Arab News have given the official DGHS figures and on-the-ground detail, with Al Jazeera noting a child who died days after vaccination likely contracted measles before the shot had time to protect him and DGHS spokesman Zahid Raihan saying "We couldn't achieve herd immunity." The Independent and AP provided human detail from Bangladeshi hospitals and explained how political upheaval and procurement delays in 2024–25 reduced coverage. On U.S. coverage, AP, BBC and Ars Technica reported Pennsylvania’s recent deaths and the state’s tally of nearly 700 cases. The AP and Independent quoted state health officials: "My thoughts are with the two families," Pennsylvania Secretary of Health Debra Bogen said, and local coroners provided causes such as acute disseminated encephalomyelitis for an 18-year-old, as reported by the Mifflin County coroner (reported in Ars Technica and The Japan Times). Ars Technica and BBC highlighted clashes between Pennsylvania officials and federal leadership on counting and reporting deaths, noting that the CDC has changed how it records deaths and that Health Secretary Robert F. Kennedy Jr. has disputed state reports. Together, the sources show two parallel problems: in Bangladesh, large-scale gaps driven by disrupted routine services and procurement delays; in the U.S., pockets of low uptake and political conflict over vaccine policy that are complicating public-health responses.

• MMR vaccine - Any of several combined vaccines against measles, mumps, and rubella

  The MMR vaccine (abbreviated as MMR) is a combination vaccine against measles, mumps, and rubella (German measles). It contains the combined measles vaccine, mumps vaccine, and rubella vaccine into a single injection. After two doses, 97% of people are protected against measles, 88% against mumps, and at least 97% against rubella. The vaccine is also recommended for those who do not have evidence of immunity, those with well-controlled HIV/AIDS, and within 72 hours of exposure to measles among those who are incompletely immunized. It is given by injection. Measles is a highly contagious viral illness that can lead to serious complications, including pneumonia, acute encephalitis, and, in rare cases, long‑term neurological disease. Pregnant women are at increased risk of severe respiratory complications and adverse pregnancy outcomes such as pregnancy loss and premature birth. The MMR vaccine is widely used around the world. As of 2012, 575 million doses had been administered since the vaccine's introduction worldwide. Measles resulted in 2.6 million deaths per year before immunization became common. This has decreased to 122,000 deaths per year as of 2012, mostly in low-income countries...
