Pennsylvania's Measles Outbreak Is the Largest in Decades in the US

Lancaster County remains the epicenter as officials say only four patients were vaccinated and the outbreak has spread to 39 counties.

  • On Monday, the Pennsylvania Department of Health reported 1,004 measles cases across 39 counties, with Lancaster County remaining the epicenter at 391 confirmed infections.
  • Health officials trace the outbreak to April west of Philadelphia, where vaccination coverage fell below the 95% threshold needed for herd immunity.
  • Pennsylvania reports a 20% hospitalization rate among its 977 patients, more than double the national 9% figure, with 69% of cases involving adults rather than children.
  • Five residents have died from measles, though the Centers for Disease Control and Prevention only recently added the fatalities to its dashboard after initial delays in federal reporting.
  • International health officials will meet in November to assess whether the U.S. has lost its measles-free status, as the nation endures its worst year for measles since 1991.
