CDC Confirmation and Immediate Context
On September 23, the U.S. Centers for Disease Control and Prevention (CDC) added one measles-related death to its national dashboard for 2026. The agency noted that the figure could change as additional information and reviews are completed. A spokesperson for the Department of Health and Human Services (HHS) said the National Center for Health Statistics (NCHS) had verified that measles was listed as the underlying cause of death. The CDC has not disclosed the location of the fatality.
Outbreak Overview and Pennsylvania Dispute
The United States has recorded 3,471 measles cases this year as of September 17, marking the worst outbreak since the early 1990s. Pennsylvania has been the hardest-hit state, reporting 835 cases, 164 hospitalizations, and four measles-associated deaths in 2026—the first measles-related deaths in the state in 35 years. The state’s health department initially reported two deaths in August, which sparked a public dispute. Health Secretary Robert F. Kennedy Jr. questioned the Pennsylvania deaths and suggested Governor Josh Shapiro had fabricated them for political purposes. Governor Shapiro responded by accusing Kennedy of sowing distrust in vaccines.
Key Data Points
- National cases: 3,471 (as of Sept 17)
- Pennsylvania cases: 835
- Pennsylvania hospitalizations: 164
- Pennsylvania deaths: 4 reported, one now confirmed by CDC
- Vaccination impact: Less than 1 % of confirmed cases occurred in individuals fully vaccinated with the two-dose measles, mumps and rubella (MMR) vaccine; nine out of ten unvaccinated contacts become infected.
Official Statements & Responses
The CDC indicated it is collaborating with the Council of State and Territorial Epidemiologists to develop a standardized case definition for measles-related deaths, aiming for consistent classification across jurisdictions. HHS spokesperson Emily Hilliard reiterated that the agency is still working on that definition and emphasized the importance of transparent communication. Associate professor Kawsar Talaat of the Johns Hopkins Bloomberg School of Public Health argued that a standardized definition is essential for objective counting, transparency, and public trust.
Political Criticism and Tension
Robert F. Kennedy Jr. publicly alleged that the Pennsylvania deaths were fabricated, while Governor Shapiro blamed the health secretary for undermining confidence in vaccines. In response, an HHS spokesperson said the agency would not “submit to political blackmail” over federal assistance, underscoring the contentious interplay between public-health reporting and political narratives.
