Pennsylvania measles outbreak surpasses 1,000 cases, largest in decades

Coverage spectrum

Covered by 10 outlets across the spectrum.

Pennsylvania’s measles outbreak has surpassed 1,000 cases this year, according to the state health department, making it the largest state outbreak in more than three decades. The department’s Monday update put the total at 1,004 cases across 39 counties, with 198 hospitalizations and five deaths. Lancaster County remains the hardest-hit area, with 391 cases. Nationally, nearly 4,000 measles cases have been confirmed this year, with Pennsylvania’s count exceeding South Carolina’s, the state with the next-highest total. The Centers for Disease Control and Prevention currently lists only two measles deaths nationwide, a discrepancy tied to a dispute over how to classify measles-related deaths between Pennsylvania Governor Josh Shapiro and U.S. Health Secretary Robert F. Kennedy Jr.
