The Pennsylvania Department of Health reported 792 measles cases on Monday, marking an increase of 25 from Friday and keeping the state at the epicenter of the nation's largest resurgence in decades. State health officials confirmed 155 hospitalized patients, up slightly from 150 earlier in the month. Lancaster County remains the hardest-hit area due to localized immunization gaps. The outbreak has sparked public health concerns and political friction between Governor Josh Shapiro and U.S. Health and Human Services Secretary Robert F. Kennedy Jr. over vaccine messaging and the official classification of measles-related deaths. The Centers for Disease Control and Prevention has not yet incorporated these fatalities into its national statistics while reviewing reporting criteria. Across the United States, authorities have recorded 3,471 cases this year. Public health experts emphasize that the standard two-dose measles, mumps, and rubella vaccine remains 97% effective at preventing the highly contagious viral infection.
