Measles cases surge to 1,277 in 2025, highest since 2000, due to low vaccination rates.

The U.S. is facing its worst measles outbreak in 33 years, with 1,277 confirmed cases across 38 states in 2025, surpassing the 2019 total. Measles was declared eliminated in 2000, but a drop in vaccination rates has led to a resurgence, especially in West Texas. Three deaths and 155 hospitalizations have been reported. Health officials warn that without improved vaccination rates, the U.S. could lose its measles elimination status.
