A 39-year-old unvaccinated woman died in Pennsylvania's ongoing measles outbreak, raising fatalities to six amid over a thousand cases statewide since April.

Pennsylvania is confronting a severe measles outbreak, with state health officials reporting 1,136 cases affecting 41 counties as of early October 2026. The outbreak, which began in April, has resulted in six deaths, including a recent fatality of a 39-year-old unvaccinated woman from Franklin County. She passed away on October 10, with underlying health conditions compounded by a probable acute cardiac event linked to measles complications, as noted by the Franklin County Coroner's office.

This latest death adds to the five previous fatalities during the outbreak, which included a newborn, a 6-week-old infant too young for vaccination, an 18-year-old, a 20-year-old, and a 40-year-old—all unvaccinated. The hospitalization tally stands at 218 individuals. Despite ongoing efforts, the outbreak continues to expand rapidly, with 157 new cases reported in the week prior to October 9.

The Pennsylvania Department of Health is reviewing the new fatality and intends to provide updates following their assessment. Measles was declared eliminated in the United States in 2000; however, recent years have seen a resurgence linked to declining vaccination rates and misinformation. Nationally, 4,080 cases have been reported in 2026, marking the highest incidence since 1991.

Health experts anticipate that the US may lose its measles elimination status when the Pan American Health Organization reviews the data in November. Notably, under CDC leadership by Health Secretary Robert F. Kennedy Jr., only two of the six Pennsylvania measles deaths have been formally included in federal reporting. Prior to these recent deaths, there had been no measles fatalities reported in the US since 2015, underscoring the outbreak's severity and public health implications.
