U.S. Measles Cases Hit Highest Level Since 2000 Elimination

Undervaccinated pockets in West Texas driving sustained spread risk undoing the nation’s measles-free status

The CDC recommends that children get their first dose of the MMR vaccine when they turn 1, but local governments in places with outbreaks or elevated risk of transmission often recommend early vaccination for infants as young as 6 months.

Hundreds of measles cases have been reported in Gaines County, Texas, where vaccination rates were far below recommended levels.
A measles advisory is shown tacked to a bulletin board outside Gaines County Courthouse on April 09, 2025 in Seminole, Texas. A second confirmed measles-related death has been reported in the city of Lubbock amidst an ongoing outbreak which began in late January. As of early April, the Texas Department of State Health Services has confirmed more than 500 cases within 22 counties, ranging from the South Plains toward the Panhandle.
