Fourth US Measles-Associated Death Reported in Pennsylvania Amid Worst Outbreak Since 1992

Pennsylvania health officials said Monday that a fourth person has died from a measles-associated illness, marking the highest death toll from the disease in the United States since 1992, according to The Guardian.

All four deaths linked to the current measles outbreak have occurred within Pennsylvania, officials said. Three of the deaths took place in 2025, with the latest fatality reported this year.

According to the report, the Centers for Disease Control and Prevention (CDC) is not including any of these deaths in its national measles death count. The Guardian attributed this discrepancy to changes made by the Trump administration in how the agency reports measles-related fatalities.

Measles, described in the report as one of the most contagious diseases known, has seen a resurgence in parts of the United States in recent years. Health officials have not yet detailed the specific circumstances surrounding the fourth death or the ages of those who died in the outbreak.

The discrepancy between state-level reporting and the CDC's national figures raises questions about how measles fatalities are being tracked and communicated to the public, though further details on the change in federal reporting protocol were not immediately available.
