The United States has recorded at least 10 measles-associated deaths in 2026 as confirmed cases nationwide climb above 5,400, according to state health officials and the Centers for Disease Control and Prevention (CDC). Two additional deaths — one in Wisconsin and one in Pennsylvania — were reported Friday, November 13.
CDC reports more than 5,400 cases
The CDC reported 5,412 confirmed measles cases in the United States as of November 12. The cases had been reported across 47 jurisdictions, according to the agency’s November 13 update. The CDC cautions that its totals reflect confirmed cases reported to the agency and may change as additional information is received.
Two more deaths reported
Wisconsin health officials confirmed the state’s second measles-associated pediatric death of 2026. The Wisconsin Department of Health Services said Friday that 649 cases had been reported in 20 counties since August, the highest number the state has seen in more than 35 years. Officials did not release further information about the child to protect the family’s privacy.
Pennsylvania also reported a measles-associated death in an unvaccinated Montour County resident. The death was the state’s seventh this year. Pennsylvania has reported 1,542 cases across 46 counties, according to reporting by The Washington Post.
Why health officials are concerned
Measles is highly contagious and spreads through the air and through close contact. It can cause serious complications, including pneumonia and inflammation of the brain. Children younger than 5, pregnant people and people with weakened immune systems face a greater risk of severe illness.
The United States declared measles eliminated in 2000, meaning there was no continuous domestic transmission at that time. The current rise in cases has renewed concern that the country could lose that status if sustained transmission continues.
What families should know
The CDC says two doses of the measles, mumps and rubella (MMR) vaccine are the best protection for most children. Parents and caregivers with questions about vaccination, possible exposure or symptoms should contact a health care provider or local health department for guidance.
