Coroners in Pennsylvania have confirmed three measles-associated deaths this year, marking the state’s first fatalities from the virus in 35 years. The most recent death, reported on Saturday, September 12, 2026, involved a 40-year-old woman in Jefferson County. Two earlier deaths involved infants from Lancaster County who were not old enough to be vaccinated. According to the Pennsylvania Department of Health, the state has recorded more than 630 cases across 37 counties in 2026, the highest volume since 1992.
The confirmations follow a public dispute between Pennsylvania Governor Josh Shapiro (D) and Health Secretary Robert F. Kennedy Jr. over the accuracy of the state's reporting. Governor Shapiro previously stated that two individuals had died of "measles-associated" causes, while Kennedy suggested the reports might have been fabricated for political purposes. The Centers for Disease Control and Prevention (CDC) has not yet included these deaths in its national dashboard, stating it requires more information due to initially conflicting reports between state and local authorities.
In Lancaster County, Coroner Stephen Diamantoni confirmed that a 6-week-old girl died of measles last month. While the infant had microcephaly, a condition typically fatal by six months, Diamantoni identified measles as the cause of death. He previously disagreed with the state regarding a different case involving an Amish newborn, whom he determined died of a ruptured spleen rather than measles. On Friday, September 4, 2026, Kennedy acknowledged the coroner's confirmation of the infant's death but noted the National Center for Health Statistics had not yet received formal death records indicating measles as the underlying cause.
For individual residents, the surge in cases has led to increased public health outreach. Pennsylvania officials reported that approximately 35,000 people were vaccinated recently, compared to a typical monthly average of 25,000. Health Secretary Dr. Debra Bogen noted that while the MMR vaccine provides 97% lifetime protection, the virus remains highly contagious, staying infectious in the air for up to two hours. Families of those who died have requested privacy, and Jefferson County officials stated no further details on the 40-year-old woman's death would be released.
The outbreak carries a significant policy precedent as international health officials prepare to meet in November to decide if the U.S. and Mexico will lose their "measles-eliminated" status. This status, granted in 2000, is at risk if a single outbreak lasts more than one year. The CDC and Health Secretary Kennedy stated that national tallies will be updated as submitted records are reviewed and verified. In the interim, Governor Shapiro has called for immediate reporting on the federal dashboard, while Kennedy maintains the agency must wait for completed reviews rather than respond to political pressure.
