3,659 confirmed cases across 47 jurisdictions as of September 24, 2026, with 40 new outbreaks confirmed this year; approx. 95% of cases are outbreak-associated (linked to a defined cluster of 3+ related cases). Three deaths were confirmed in 2025, two unvaccinated children in Texas and one unvaccinated adult in New Mexico, the first measles deaths in the U.S. since 2015. In 2026, Pennsylvania has reported four measles-associated deaths: two infants too young to be vaccinated and two unvaccinated people, aged 18 and 40. The 2026 case count has already surpassed 2025's full-year total of 2,289, with about three months still remaining in the year; PAHO (Pan American Health Organization) is scheduled to formally review U.S. measles elimination status, held since 2000, in November 2026, and infectious disease experts broadly expect that status to be lost.
No active U.S. outbreak, but the 2022 case of paralytic polio in an unvaccinated adult in New York, the first U.S. case in nearly a decade, highlighted the risk posed with the increase in under-vaccinated communities. Vaccine-derived poliovirus was detected in New York wastewater during the same period. The WHO has maintained polio as a Public Health Emergency of International Concern (PHEIC) since 2014, with the status reaffirmed in March 2026.
Confirm tetanus/diphtheria, whooping cough, hepatitis A/B, and typhoid are current before any international trip, per WHO guidance.
