Launch Catch-Up — October 23 CDC Update, Rechecked October 26

The United States had recorded 4,588 confirmed measles cases in 2026 as of October 22, exceeding twice the 2,289 cases reported for all of 2025, according to the Centers for Disease Control and Prevention.

The agency’s October 23 update lists 43 new outbreaks this year and says 4,404 cases, or 96% of the total, are associated with outbreaks. Some of those outbreaks began in 2025.

The national total includes 4,570 cases reported by 47 jurisdictions and 18 among international visitors.

The figures are preliminary and reflect confirmed cases notified to the CDC, rather than every suspected infection. National and state totals can differ because health departments report on different schedules.

These are the CDC’s dated figures through October 22, not a live count of infections occurring on October 26.

The CDC defines an outbreak as three or more related cases. Its national figures include only confirmed infections that jurisdictions have notified to the agency; probable cases are excluded. The agency notes that states can have more current information about local outbreaks.
