STAT News reports that the current U.S. measles outbreak has become the worst since 1991. The Centers for Disease Control and Prevention has updated its online case counter to reflect one additional death. Separately, state officials in Pennsylvania report that four unvaccinated people have died of measles there in recent weeks.
STAT News describes measles as one of the most contagious diseases known, a characterization that underlies why sustained vaccination coverage has historically kept it in check in the United States. The 1991 benchmark cited by the outlet marks the last time case counts reached comparable levels, before the disease was declared eliminated domestically in 2000.
The report ties the current scale of the outbreak to gaps in vaccination coverage, noting that all four Pennsylvania deaths occurred in unvaccinated individuals. The CDC’s counter update and the state-level fatality reports together indicate that the outbreak has produced multiple deaths this cycle, though the story material does not specify a national death toll beyond the counter’s single added entry.
No additional detail on transmission chains, affected regions beyond Pennsylvania, or vaccination rate figures is provided in the available reporting. The Specola notes the story as developing, based on STAT News’s account published September 24, 2026, and will record further figures as they are confirmed by public health authorities.
