WHO Warns Measles Resurgence Is Putting Elimination at Risk

Falling vaccination coverage plus strained surveillance leave tens of millions of children unprotected worldwide.

Overview

  • WHO’s new report estimates 11 million infections and 95,000 deaths in 2024, with 59 countries facing large or disruptive outbreaks and a quarter occurring in places that had eliminated measles.
  • Global coverage remains below the 95% two‑dose threshold at 84% for the first dose and 76% for the second, leaving more than 30 million children inadequately protected, as funding cuts threaten lab surveillance networks.
  • The Region of the Americas lost its measles‑free status after sustained transmission in Canada, and WHO officials cautioned that the United States’ status is vulnerable.
  • Mexico has reported 5,386 cases across 27 states with 23 deaths, most in Chihuahua, where community transmission continues, according to the government’s daily outbreak report.
  • U.S. authorities have confirmed 1,798 cases in 42 states this year with three deaths, while Argentina issued a national alert after four imported unvaccinated cases and Uganda reported 74 cases with 11 child deaths in Napak district.
