Arizona, Utah Measles Outbreak Threatens US Elimination Status

Measles outbreaks in Arizona and Utah are showing no signs of slowing, placing the United States in jeopardy of losing its elimination status for the vaccine-preventable disease. Health officials are particularly concerned that the upcoming holiday travel and gatherings could significantly accelerate transmission.

Experts warn that if sustained transmission continues through January 2026, the US would no longer be considered measles-eliminated and the disease would become endemic. This concerning trend is largely attributed to pockets of communities with low vaccination rates, making them highly susceptible to rapid spread.

Areas like Washington County, Utah, and Mohave County, Arizona, have reported significant case numbers, with vaccination rates for kindergartners in Mohave County at just 78%. The national rate for recommended MMR vaccine doses is also below the crucial 95% threshold, indicating a broader vulnerability.
