U.S. Measles Cases Hit 35-Year High with 2,318 Confirmed Cases

2,318 confirmed measles cases reported in 2026, surpassing last year's high of 2,289.
Vaccine hesitancy continues to drive the outbreak, particularly among unvaccinated children, with 45 states reporting cases.
A decision in November will determine if the U.S. will lose its elimination status for measles, following a year of increasing transmission.
