The Centers for Disease Control and Prevention reported Friday that the United States had recorded 5,412 confirmed measles cases this year through November 12. That is 230 more than in the agency’s previous weekly update and more than twice the 2,289 cases recorded in all of 2025.
The CDC’s latest tally includes 591 hospitalizations, about 11 percent of confirmed cases. Children younger than 5 accounted for 951 cases, and 160 of them were hospitalized, about 17 percent. The agency counted 18 cases among international visitors and 5,394 reported by U.S. jurisdictions. The weekly increase measures cases newly added to the tally. Some illnesses began before the latest reporting week. Among children and teenagers ages 5 to 19, the CDC listed 2,183 cases and 98 hospitalizations, about 4 percent. That group had more reported cases than children under 5, but a smaller share needed hospital care.
Pennsylvania and Wisconsin report deaths
Pennsylvania health officials reported the state’s seventh measles-associated death this year, involving a Montour County resident. The state had recorded 1,542 cases across 46 counties and 305 hospitalizations by Friday, Reuters reported, citing the state health department. Pennsylvania publishes its criteria for counting measles-associated deaths alongside its outbreak resources.
The Wisconsin Department of Health Services reported a second pediatric death linked to the state’s outbreak, according to Wisconsin Public Radio. The station reported that the child was in Grant County and that state officials withheld further details to protect the family’s privacy. Wisconsin had recorded 651 cases across 22 counties, according to WPR’s Friday update. That is the state’s own tally, which can differ from the CDC’s Thursday cutoff.
The federal table lists six deaths for 2026 and says that figure may change as reviews are completed. The CDC says it is working with state and territorial epidemiologists on a standard definition for measles-associated deaths. The state announcements and the federal total cover different reporting processes, so the figures cannot be added together.
What to do after a possible exposure
The CDC advises anyone who thinks they were exposed to call a health care provider right away. Have your vaccination record handy if you can. If you develop symptoms, call ahead before going to a clinic so staff can prepare to limit other patients’ exposure. A clinician can advise on time-sensitive options for people without immunity.
The outbreak has also prompted a review of U.S. measles elimination status.
For local notices, the CDC’s case page links to health departments with current outbreak information. Wisconsin’s measles dashboard and Pennsylvania’s measles page publish state-specific guidance.
