NBC News • • general
Key Points:
- The CDC confirmed one measles-related death in 2026 but did not disclose details about the individual or location, despite Pennsylvania reporting four measles-associated deaths recently.
- Pennsylvania’s Health Department defines a measles-associated death as one occurring within 30 days of symptom onset with a positive test, considering medical history and exposure, but is unsure which death the CDC acknowledged.
- The CDC is collaborating with epidemiologists to establish a standardized case definition for measles-related deaths to improve reporting consistency.
- As of now, the CDC has confirmed 3,471 measles cases across 45 states and D.C. in 2026, with over 300 hospitalizations; Pennsylvania alone has 835 cases and 164 hospitalizations, mostly among unvaccinated individuals.
- The MMR vaccine, given in two doses typically by age 5, provides about 97% protection against measles, and booster doses can be administered to infants as young as 6 months during outbreaks.
