Denver (Aug. 15, 2025) — The Colorado Department of Public Health and Environment and Mesa County Public Health have confirmed a case of measles in a Mesa County resident. The adult, who had not received the measles, mumps, and rubella (MMR) vaccine, has no known connection to other recent exposures reported in Colorado and has not traveled outside the state. The lack of a clear source of infection suggests that this case may be the result of community transmission in the Grand Junction area. Mesa County Public Health is investigating the case.
