DDPHE releases locations for potential measles exposures in Denver

Published on June 13, 2025

The Colorado Department of Public Health and Environment, Boulder County Public Health, and the Denver Department of Public Health and Environment (DDPHE) have confirmed a case of measles in a Boulder County resident and are notifying members of the public of additional areas for potential measles exposures in Denver County. The fully vaccinated adult recently traveled to Europe, where there are a large number of measles cases.

Getting vaccinated is the best way to protect yourself, your family, and your community. Measles is highly contagious and can sometimes lead to serious health problems, but it is a vaccine-preventable disease. Symptoms include fever, cough, runny nose, red eyes, and a characteristic rash that usually starts several days later on the face and spreads. The measles, mumps, and rubella (MMR) vaccine provides strong protection. Breakthrough cases typically experience milder illness and are less likely to spread the virus to others.

Known exposure locations:

Based on available information, anyone who was in the following locations during the dates and times listed may have been exposed to measles and should monitor for symptoms for 21 days after exposure and consider avoiding public gatherings or high-risk settings. Monitoring for symptoms is especially critical for people who have not been vaccinated with the MMR vaccine. Locations will be updated, as necessary.

What to do if you may have been exposed and aren't feeling well:

People exposed to measles typically develop symptoms 7 to 21 days after exposure. If you were at these locations during the exposure window and develop symptoms, immediately contact your health care provider by phone. If you do not have a provider, call an urgent care center or emergency department and explain that you may have been exposed to measles. Calling ahead helps prevent additional exposures.

What Denverites Should Do to Protect Themselves

• Know your vaccination status
• • If you do not know whether you are vaccinated against measles, check Colorado's immunization database at copublicportal.state.co.us or with your healthcare provider.
  • You could also check with family members to see if they have your childhood records.
  • Some schools, colleges, universities or employers might keep records for former students or employers. If you're unable to find a record of your immunizations elsewhere, consider checking one of these locations.
• Get vaccinated if you are not vaccinated already
• • Check with your healthcare provider to receive the vaccine.
  • People born before 1957 are generally considered to be immune and do not need a vaccine.

If you are not vaccinated and are not planning to receive the vaccine, monitor yourself closely for symptoms. If symptoms develop, immediately contact your health care provider by phone. If you do not have a provider, call an urgent care center or emergency department and explain that you may have been exposed to measles. Calling ahead helps prevent additional exposures. If you have additional questions for our DDPHE public health nursing team, contact them by email. They can help answer question about measles, vaccines and more.
