CDC: 5,182 Confirmed Measles Cases in the U.S. in 2026 as of November 5, More Than Double the 2025 Total
The Centers for Disease Control and Prevention (CDC), in a surveillance page updated November 6, reported 5,182 confirmed measles cases in the United States in 2026 as of November 5, more than double the 2,289 confirmed cases recorded for the full year of 2025.
CDC said 43 new measles outbreaks, defined as three or more related cases, were reported in 2026. Ninety-six percent of confirmed cases, 4,993 of 5,182, are outbreak-associated: 3,608 from outbreaks that started in 2026 and 1,385 from outbreaks that started in 2025.
The figures include only confirmed cases formally notified to CDC by jurisdictions as of noon each Thursday, the agency said, noting it is aware of additional probable cases being reported locally. State health departments hold the most up-to-date information for their jurisdictions.
Measles spreads through the air. CDC recommends that children receive the measles, mumps and rubella (MMR) vaccine on the routine schedule, and advises people with fever and rash to seek care promptly and notify the provider in advance.
