CDC Confirms Two Measles Deaths Amid Nationwide Outbreak
By Drooid · · How we work
Core Event
On Tuesday the U.S. Centers for Disease Control and Prevention (CDC) announced two measles-related deaths, bringing the national death toll to two. The agency reported 3,659 confirmed cases as of 24 September, the highest annual total since 1991 and spread across 45 states and Washington, D.C. The CDC did not disclose the states where the fatalities occurred.
Background & Context
Measles was declared eliminated in the United States in 2000, yet the disease has resurged, with officials linking the rise to growing vaccine skepticism. Members of former President Donald Trump’s administration, including Health and Human Services Secretary Robert F. Kennedy Jr., have been criticized for promoting debunked claims that associate vaccines with autism. In August 2025, Trump signed an executive order that split the combined measles-mumps-rubella (MMR) vaccine into three separate shots, a move public-health experts warned could increase infection risk by requiring additional visits. The CDC also faces staffing challenges after nearly 30 % of its workforce was reduced following the 2025 federal employee layoffs.
Data & Statistics
- Confirmed cases nationwide: 3,659 (as of 24 September).
- Pennsylvania: > 900 cases, 176 hospitalizations, four measles-associated deaths (two unvaccinated adults, two infants too young for vaccination).
- Age distribution in Pennsylvania: majority aged 25-49, followed by 18-24.
- Fully vaccinated cases nationwide: < 1 % (four individuals).
- Kindergarten MMR coverage 2025-26: 92.4 % (down from 95.2 % in 2019-20).
- CDC recommends two MMR doses: first at 12-15 months, second at 4-6 years; one dose is 93 % effective, two doses 97 % effective.
Official Statements & Responses
The CDC said it is collaborating with state epidemiologists to create a standard definition of measles-related deaths and noted that the death count “is subject to change” as reviews continue. CDC guidance continues to stress two MMR doses for optimal protection.

- “People who have been exposed may be instructed to quarantine or keep really close eye on their symptoms for up to 21 days because that's how long it can really take for measles to show itself and you could potentially spread and infect others without even knowing it,” — Dr. Alok Patel
