CDC Reports Over 5,100 Confirmed Measles Cases in US for 2026, Exceeding Double Last Year's Total

The Centers for Disease Control and Prevention (CDC) reported 5,182 confirmed measles cases in the United States as of November 5, 2026, marking a 6.8% increase from the previous week and more than double the total cases reported in 2025. State health departments also reported three additional measles-associated deaths in the past week, bringing the total reported deaths nationwide in 2026 to eight, though the CDC's official count stands at four. The majority of cases (96%) are outbreak-associated, with 43 new outbreaks reported in 2026. The Department of Homeland Security (DHS) now recommends an early MMR vaccine dose for certain infants aged 6 to 11 months at increased risk of exposure.
