CDC Reports Third U.S. Measles Death, Tally Rises Above 4,500 Cases This Year

The death added to the federal total as the U.S. now records more than 4,400 measles cases nationwide.

The Centers for Disease Control (CDC) has announced a third measles‑related death in the United States, marking what may be the country’s largest outbreak in recent memory.

The agency refused to name the state where the fatal case occurred on Tuesday. Its own count of roughly 4,410 measles cases remains below the totals reported by state health departments, especially in Pennsylvania—the hardest‑hit state with more than 1,200 cases and five deaths as of Monday.

CDC officials later verified through the National Center for Health Statistics (NCHS) that the fatality was caused by measles. As a result, the dead toll is subject to change pending further review.

The overall case total stands at 4,410 across the nation as of October 15, while Pennsylvania alone has reported 42 counties affected. The epidemic has spread well beyond its initial concentration in Lancaster County.

The CDC’s reliance on NCHS mortality data rather than direct state reports has drawn scrutiny. In response, the agency is collaborating with the Council of State and Territorial Epidemiologists to develop a standardized definition for measles deaths until a harmonized metric is in place.
