Pennsylvania reports third measles death as state outbreak reaches 676 cases

Fatality in Jefferson County

A 40-year-old unvaccinated woman in Jefferson County, Pennsylvania, died on Saturday, 12 September 2026, due to suspected measles complications. The immediate cause of death listed on a preliminary death certificate viewed by The New York Times was respiratory failure due to suspected measles. Jefferson County Coroner Greg Furlong stated on Sunday that confirmatory laboratory testing is underway after nasal swabs were sent to the state laboratory. The woman had pre-existing chronic obstructive pulmonary disease and was on around-the-clock supplemental oxygen, making her particularly vulnerable to severe respiratory illness. Although state lab testing remains pending, the patient had recently been exposed to a confirmed measles case and presented classic symptoms, including the rash that begins on the face and spreads down the body.

Furlong released a statement addressing the fatality.

This is a heartbreaking loss for the family and an unfortunate reminder that measles can be a serious and potentially life-threatening disease.

State outbreak metrics

The death marks the third measles-associated fatality in Pennsylvania this year. According to the Pennsylvania Department of Health, the state had recorded 676 cases across 37 counties as of Friday, 11 September 2026, with 108 new infections registered during the preceding week. The outbreak remains heavily concentrated in agricultural communities in Lancaster and Mifflin counties, with Lancaster County alone accounting for 295 cases. State records indicate that 124 infected individuals have required hospitalization, nearly one third of whom were children. Less than 1% of all recorded cases in the state occurred in individuals who were fully vaccinated.

Jason Stiver, the chief deputy coroner and public relations officer for Jefferson County, urged residents to follow protective public health measures.

Measles is highly contagious and can result in serious respiratory illness, hospitalization, and in rare cases like this, death. We encourage residents to stay informed, follow guidance from public health officials, and take appropriate steps to protect themselves and their families.

Classification dispute

The death follows a political dispute between state and federal officials over two prior fatalities reported in Lancaster County in August. Those earlier cases involved two unvaccinated infants, one born with a genetic defect and another who died of a spleen laceration on 14 August after testing positive for measles. Lancaster County Coroner Stephen Diamantoni said the examining pathologist did not believe the virus caused the infant's death, while state health authorities noted that measles can cause spleen inflammation that increases rupture risk. US Health Secretary Robert F. Kennedy Jr. questioned whether those cases were measles-related and asked the CDC to exclude them from federal outbreak counts. Pennsylvania Governor Josh Shapiro accused Kennedy of generating public confusion about vaccination.

National infection trajectory

Federal figures from the CDC indicate that nationwide measles cases reached 3,294 across more than 45 states as of mid-September 2026. This exceeds the 2,289 total cases and three deaths recorded across the country in 2025. CDC data shows a steady decline in kindergarten vaccination rates, including the measles, mumps, and rubella (MMR) vaccine. In the United States, roughly one in five unvaccinated individuals who contract measles requires hospital care, with child mortality from measles complications ranging between one and three deaths per 1,000 cases.
