Pennsylvania reported its third measles-related death in less than three weeks after a 40-year-old unvaccinated woman with underlying health conditions died from complications, according to a local coroner. The case has intensified scrutiny of the ongoing U.S. measles outbreak, described as the worst in decades, at a time when flu season is also approaching. Adding to the concern, the CDC has publicly questioned two of the Pennsylvania measles deaths, prompting experts to worry about the reliability of federal health data during the outbreak. The dispute has raised broader fears about how the agency is tracking and communicating disease threats as vaccination rates face pressure nationwide.
