Follow-up: U.S. Measles Cases Rise to 5,412, Up 230 in a Week, 96% Outbreak-Associated
Atlanta — The U.S. Centers for Disease Control and Prevention (CDC) updated its national measles case and outbreak data on November 13: as of November 12, 5,412 confirmed measles cases had been reported in the United States in 2026, up 230 from the previous update of 5,182 cases (as of November 5).
Of the 5,412 cases, 5,394 were reported by 47 jurisdictions, including California, Texas, Pennsylvania and New York, and 18 cases were reported among international visitors to the United States. CDC notes that the page counts only confirmed cases notified by jurisdictions, not probable cases, and that state health departments hold the most up-to-date local information.
On outbreaks, 43 new measles outbreaks (three or more related cases) have been reported in 2026, and 96% of confirmed cases, 5,216 in total, are outbreak-associated: 3,831 from outbreaks that started in 2026 and 1,385 from outbreaks that started in 2025.
CDC has confirmed six measles-associated deaths in the United States in 2026, a figure subject to change as reviews are completed. CDC is working with the Council of State and Territorial Epidemiologists (CSTE) to develop a standardized case definition for deaths due to measles, to promote consistent classification and reporting across jurisdictions.
By comparison, 2,289 confirmed measles cases were reported in the United States in all of 2025, so the 2026 total to date is already more than double last year's full-year figure. Measles was declared eliminated in the United States in 2000, and a Pan American Health Organization committee decision on the country's measles elimination status has not yet been announced.
