What happened
Measles outbreaks are growing in several U.S. states, including Iowa, where 50 confirmed cases had been identified in 2026 as of November 4, and Wisconsin, which has recorded 477 confirmed cases across 15 counties. A Wisconsin infant has died from the disease, the first measles death in the state since 1990. The Pan American Health Organization is now evaluating whether the United States and Mexico have lost their measles elimination status.
Why it matters
A loss of elimination status would be a major setback for the United States, and the decision could define the legacy of Health Secretary Robert F. Kennedy Jr., a vaccine skeptic, according to Politico.
