The Colorado Department of Public Health and Environment, in coordination with the Adams County Health Department, has confirmed a case of measles in a child under five years old from Adams County. The child, who had not received the measles, mumps, and rubella (MMR) vaccine, traveled with family to Chihuahua, Mexico. There is currently an ongoing measles outbreak in that region. The child remains hospitalized.
According to public health officials, measles is highly contagious but can be prevented through vaccination. “Getting vaccinated is the best way to protect yourself, your family, and your community,” stated the release.
Measles symptoms typically start with fever, cough, runny nose, and red eyes. A rash appears several days later on the face and spreads across the body. Health authorities advise that people who have not been vaccinated can still receive the MMR vaccine within 72 hours of exposure to help prevent illness. In certain cases, immunoglobulin given within six days may also help prevent or lessen illness.
Officials identified Children’s Hospital Colorado Emergency Department at 13123 E. 16th Ave., Aurora as a potential exposure site on Tuesday, Aug. 12 between 6:36 p.m. and 10:16 p.m. Those present during this time are advised to monitor for symptoms for 21 days after exposure—through Sept. 2—and to contact their healthcare provider before seeking care if symptoms develop.
Further information about measles symptoms, transmission methods, vaccine recommendations, current case updates in Colorado for 2025, and additional exposure locations can be found on the CDPHE measles webpage.
