Pennsylvania's measles outbreak has climbed past 1,500 cases, with the state health department reporting 1,505 cases as of Monday, November 9. The outbreak, the largest in the country, has now reached Bucks County, where the health department announced a new case in a resident who recently traveled to an area of central Pennsylvania that has reported many cases this year.
The state has recorded 290 hospitalizations and six measles-associated deaths in the outbreak, according to the Pennsylvania Department of Health's measles dashboard. Cases have been reported in two-thirds of the state's counties.
Pennsylvania leads the nation in 2026 measles cases. The Centers for Disease Control and Prevention reported 5,182 confirmed measles cases across the United States as of November 5, with 96 percent associated with outbreaks. The CDC listed Pennsylvania with 1,335 cases as of that date, followed by South Carolina with 670 and Utah with 536, and the state total has continued to rise since.
Bucks County Health Department Director Dr. David Damsker announced the new case in a statement on Monday. Health officials continue to urge residents to make sure their measles vaccinations are up to date.
