Pennsylvania health authorities on Monday confirmed the state's sixth death tied to measles, solidifying its position as the national epicenter of an outbreak that has now infected more than 1,000 people statewide.
The Franklin County Coroner's Office announced that a 39-year-old woman with multiple underlying health conditions died after a recent measles diagnosis that had been treated. The office investigated the death on Oct. 10. In a statement, the coroner said the case marked the first death in the county in many years involving a patient with a recent measles history and met the Pennsylvania Department of Health's criteria for a measles-associated death.
The state's weekly dashboard does not yet reflect this latest fatality because Monday was a federal holiday, meaning the count will not be updated until Wednesday. Even so, Pennsylvania has already surpassed 1,000 total infections, more than any other state. Nationally, the U.S. has recorded over 4,000 confirmed measles cases this year—the worst transmission in decades, as detailed in a recent report on the nationwide surge in measles cases.
The gap between Pennsylvania's six reported deaths and the two acknowledged by the Centers for Disease Control and Prevention stems from a change in how the Trump administration tallies measles fatalities. Earlier this year, when the state reported its first measles-related deaths, federal officials questioned whether any had actually occurred, noting that local jurisdictions had no knowledge of them.
In September, the CDC shifted from the Nationally Notifiable Diseases Surveillance System—which relies on real-time case reporting from local jurisdictions—to the National Center for Health Statistics, a more comprehensive data set that lags between when a death happens and when the cause is officially recorded. The change has created a discrepancy that state officials say undercounts the true toll.
Public health experts warn that the mounting death toll underscores the severity of the outbreak, which has been fueled by declining vaccination rates in pockets of the country. Pennsylvania's case count alone accounts for roughly a quarter of the national total.
“This is the first death in Franklin County in many years with a patient with a recent history of a measles diagnosis and meets the definition set forth by the Pennsylvania Department of Health for a measles-associated death,” the coroner said in the advisory.
The state's dashboard update on Wednesday is expected to include the latest death, bringing the official state tally to six. Meanwhile, the CDC's count remains at two, a disparity that could complicate federal response efforts and public messaging as the outbreak continues.
As the nation grapples with the resurgence of a disease once considered eliminated, Pennsylvania's experience highlights the challenges of tracking and containing measles in a fragmented public health system. With over 4,000 cases nationwide, the outbreak shows no signs of abating.
