Unvaccinated 40-year-old Pennsylvania woman dies of measles complications, third death tied to outbreak

An unvaccinated 40-year-old woman died of measles complications in Pennsylvania on Saturday, Sept. 12, Jefferson County Coroner Greg Furlong said — the state's third measles death this year and its first adult, after two infant deaths. Pennsylvania has confirmed 676 cases across 37 counties with 124 hospitalized; the national count passed 3,000, the most since 1991.

• Lancaster County, an outbreak center, has 87.6% two-dose kindergarten MMR coverage, against the roughly 95% herd-immunity threshold; Pennsylvania overall sits at 92.7%.
• Pennsylvania has not requested a CDC Epi-Aid outbreak team despite repeated offers, CDC Director Erica Schwartz said; CDC's site listed zero 2026 deaths as of Sept. 11, before hers.
