In 2026, the U.S. recorded over 2,289 measles cases by mid-July, surpassing the previous record of more than 2,200 cases in 2025. This surge has put the country at risk of losing its measles elimination status since 2000; two deaths occurred due to measles in Pennsylvania this August, marking the state’s first measles-related fatalities in 35 years. The increase is attributed primarily to declining vaccination rates and lower community immunity thresholds across multiple states.
