Pennsylvania records third measles-related death amid outbreak

Pennsylvania has recorded its third measles-related death, an unvaccinated 40-year-old woman, amid a growing outbreak of 676 cases. The death follows those of two infants in August 2026. However, U.S. Health Secretary Robert F. Kennedy Jr. has disputed the causes of death, leading the CDC to withhold them from official federal tallies. This unprecedented clash has sparked intense political tension between Governor Josh Shapiro and federal health officials, raising concerns among public health experts.
