Bangladesh is battling measles. It's a 'real warning' to other nations

Bangladesh is battling to contain the world’s worst measles outbreak , a crisis exacerbated by weak data, inadequate outreach and vaccination gaps that experts say offers a warning to other nations about the deadly risk of falling immunisation rates.

Bangladesh almost achieved that in recent years but in 2025 coverage dropped. A Reuters review of WHO documents, alongside interviews with more than a dozen scientists, health workers and officials, shows Bangladesh was also hampered in its emergency response by data that left out millions of children, shortcomings in preparation and a failure to reach enough parents. “This is a real warning to every country,” said Mark Jit, a WHO vaccine adviser and professor at the School of Global Public Health at New York University. Preventing an outbreak through vaccinations was easier, cheaper and safer than responding to an emergency, he said. Bilkis and other parents take…
