Summary

  • An unvaccinated Lancaster County resident who tested positive for measles has died, marking Pennsylvania’s fifth measles-associated death of 2026.
  • The outbreak has grown to 943 confirmed cases, 176 hospitalizations and spread across 39 counties; only four cases involved vaccinated people, less than 1% of the total.
  • Lancaster and Mifflin counties’ agricultural communities remain the center of transmission, and the state logged 40 new positive cases by Sept. 28.
  • State health centers have given more than 5,500 MMR shots through 180 pop-up clinics since late April, with dozens more clinics planned.
  • The death comes amid a dispute with the CDC, which has not included Pennsylvania’s measles deaths in its national tally after a Trump administration reporting change; the U.S. has reported more than 3,600 cases this year.
