CDC reports 5,182 confirmed US measles cases for 2026

The United States recorded 5,182 confirmed measles cases for 2026 as of November 5, the Centers for Disease Control and Prevention reported in an update on November 6.

The preliminary national count includes 5,164 cases reported by 47 jurisdictions and 18 among international visitors. New York City and New York State appear separately in the CDC’s jurisdiction list, which also includes the District of Columbia.

For comparison, the agency lists 2,289 confirmed cases for the whole of 2025. The 2026 figure covers only the count available through November 5, so the two figures represent different periods. Both years’ counts are preliminary.

In its national tracking report, CBS News said the count had passed 5,000 by early November. Reporter Grace Manthey wrote that the CBS data team follows releases from state health departments and the CDC to track confirmed cases across the country.

The CDC reported 43 new outbreaks in 2026. The agency defines an outbreak as three or more related cases; the figure counts new outbreaks reported during the year. Its case update reflects confirmed notifications received by Thursday noon, while state and federal reporting schedules differ.
