US Measles Cases Surpass 5,400 in 2026, Prompting Review of Elimination Status

The CDC reports 5,412 confirmed measles cases and 10 associated deaths in the U.S. this year, a significant rise from 2025. This increase has led the Pan American Health Organization to review whether the U.S. will retain its measles elimination status, held since 2000, due to the sustained transmission and severity of the outbreak.
