A 40-year-old Pennsylvania woman has died from complications related to measles, marking the third such death in the state this year. The county coroner described the death as "measles-related."
The woman, a resident of Jefferson County, died Saturday. The county is located approximately 50 miles northeast of Pittsburgh. Officials have not released further details about the case, including whether the woman was vaccinated.
The two previous measles-related deaths in Pennsylvania this year involved infants. One infant died shortly after birth due to complications from a ruptured spleen, with measles listed as a significant condition. The other infant, a 6-week-old girl with a genetic defect that made her highly susceptible to infection, died from measles. Neither infant was old enough to have received the measles vaccine, as the first dose is typically administered around one year of age.
As of Friday, Pennsylvania had recorded 676 measles cases across 37 of its 67 counties. Of these cases, 124 resulted in hospitalizations. According to the Pennsylvania Department of Health, four of the reported cases involved individuals who had been vaccinated against measles.
The discrepancy between the state's reported measles-related deaths and data from the U.S. Centers for Disease Control and Prevention (CDC) has been noted. The CDC's National Center for Health Statistics had not, as of Sunday, recorded any death certificates from 2026 listing measles as the underlying cause. Previous reports on the two infant deaths had also led to disagreements between the administration of Pennsylvania's Governor Josh Shapiro and the Trump administration.
