Denver (Aug. 18, 2025) — The Colorado Department of Public Health and Environment and Mesa County Public Health have confirmed an additional case of measles in a Mesa County resident. The adult, whose vaccination status is unknown, may have had a common exposure with the first Mesa County case reported last week. Mesa County Public Health is investigating the case.
In addition, CDPHE, the Denver Department of Public Health and Environment, and Denver International Airport (DEN) are notifying the public of a possible measles exposure at Denver International Airport. The out-of-state traveler with a confirmed case of measles arrived at gate C51 and boarded another flight at gate C50 on the C Concourse at DEN on Tuesday, Aug. 12.
“This incident serves as a reminder that travel in crowded public spaces, such as airports, increases the risk of exposure to various communicable diseases. It is important for everyone to stay up to date on their vaccinations, especially before traveling, to protect themselves and others,” said Dr. Rachel Herlihy, Deputy Chief Medical Officer and State Epidemiologist.
Measles is a highly contagious, but preventable disease. Getting vaccinated with the measles, mumps, and rubella (MMR) vaccine is the best way to protect yourself, your family, and your community.
Symptoms and prevention:
Measles symptoms begin with fever, cough, runny nose, and red eyes, followed by a rash that usually starts several days later on the face and spreads. If you have not had the MMR vaccine, you can still get it within 72 hours of exposure to help prevent illness. In some exposure cases, immunoglobulin given within six days may also help prevent or lessen illness.
Known exposure locations:
Based on available information, anyone who was in the locations below at the listed dates and times may have been exposed. If you were there, watch for symptoms for 21 days after exposure. If symptoms develop, call your health care provider, urgent care, or emergency department before going in, and tell them you may have been exposed to measles. This helps prevent further spread. Monitoring for symptoms is especially critical for people who have not been vaccinated with the MMR vaccine.
We will update locations as necessary.
