Pennsylvania reports sixth measles death as state outbreak tops 1,000 cases

Pennsylvania confirmed its sixth measles-related death on October 12, 2026, as the state's outbreak surpassed 1,000 cases, marking the worst single U.S. outbreak since 1991. The victim, an unvaccinated 39-year-old woman with underlying conditions, died in Franklin County. Meanwhile, a dispute between Governor Josh Shapiro and Health Secretary Robert F. Kennedy Jr. highlights federal-state friction, with the CDC reporting only two national deaths due to new mortality tracking rules.
