Public health officials in Colorado have reported a new case of measles in Mesa County. The Colorado Department of Public Health and Environment (CDPHE) and Mesa County Public Health confirmed that the patient is an adult whose vaccination status is not known. Authorities believe this person may have been exposed to the same source as another recent measles case in the county. An investigation into the latest case is ongoing.
In addition, CDPHE, along with the Denver Department of Public Health and Environment and Denver International Airport (DEN), has alerted the public about a possible measles exposure at DEN. Officials say an out-of-state traveler with a confirmed case of measles was present at gate C51 and later boarded another flight from gate C50 on the airport’s C Concourse on Tuesday, August 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 spreads easily but can be prevented through vaccination. The MMR vaccine protects against measles, mumps, and rubella.
Symptoms typically start with fever, cough, runny nose, and red eyes before a rash appears several days later. People who have not received the MMR vaccine can still get vaccinated within 72 hours after exposure to help prevent illness. In some cases, immunoglobulin given within six days may also help reduce symptoms or prevent disease.
Health officials have identified several locations where people may have been exposed between August 10–15:
– Enjoy Church (Grand Junction)
– Jimmy John’s (Grand Junction)
– Appleton Clinic (multiple dates/times)
– Chick-fil-A (Grand Junction)
– Denver International Airport C Concourse
– Maverik Gas Station (Fruita)
– McDonald’s (Grand Junction)
Those who were at these places during specified times are advised to watch for symptoms for 21 days after potential exposure. Anyone who develops symptoms should contact their healthcare provider before visiting any medical facility to avoid spreading illness further.
