US Measles Cases Hit 1,753 as Utah-Arizona Outbreak Expands
CDC links Texas, Utah, and Arizona measles outbreaks to strain 9171; 92% of 1,723 cases this year involve unvaccinated or unknown vaccination status individuals.
- On Nov. 19, 2025, the Centers for Disease Control and Prevention linked the Texas measles outbreak to cases in Utah and Arizona, noting subtype 9171 first detected on Jan. 20 in Gaines County, Texas.
- The C.D.C. says low vaccination and multiple importations have fueled transmission, with about 92% of infections among unvaccinated people or those with unknown status and 152 importations from at least 47 countries.
- More than 180 cases make the Utah–Arizona cluster the largest, and St. George Regional Medical Center and hospitals in Cedar City are exposure sites, but Dr. Leisha Nolen said, "We have not seen people get infected in the health systems."
- If transmission continues into January, health officials warn the United States could lose its measles elimination status, with Canada having lost it last week and three measles deaths nationwide this year.
- This month the C.D.C. took the outbreak data to the Pan American Health Organization and works with Canada and Mexico on sequencing while response teams track cases as vaccination progress slows.
