Notification provides possible public exposure area

Denver (March 12, 2026) — The Colorado Department of Public Health and Environment and Broomfield Public Health and Environment have identified two additional cases of measles and are investigating another in Broomfield County residents. All three individuals are household contacts of a previously-confirmed case. Officials are notifying the public about a new potential exposure location related to these cases.

To prevent further spread, public health protocols require unvaccinated household members of confirmed cases to quarantine. Two of the new cases were already in quarantine due to their vaccination status. The third individual was not in quarantine because they were previously vaccinated. While the measles, mumps, and rubella (MMR) vaccine is highly effective, breakthrough cases can occur, especially following prolonged exposure within a household. Breakthrough cases typically experience milder illness and are less likely to spread the virus to others.

Measles is a highly contagious disease. Getting the MMR vaccine is the best way to protect yourself, your family, and your community.

Known exposure location

Based on available information, anyone who was in the location at the listed date and time may have been exposed to measles. We will add any additional exposure locations to the CDPHE exposures webpage as they are identified.

| Location | Date/time | When symptoms may develop |
| --- | --- | --- |
| Bout Time Pub & Grub
5225 W. 80th Ave
Arvada, CO 80003 | Tuesday, March 10 – Wednesday, March 11
8 p.m. – 12:30 a.m. | Through April 1 |

What to do if you were exposed

• Get vaccinated immediately: If you have not had the MMR vaccine or aren’t sure of your status, you can get it within 72 hours of exposure to help prevent illness. For anyone at the exposure location, this means getting a vaccine by 8 p.m. this Friday, March 13. In some cases, immunoglobulin given within six days may also help prevent or lessen illness.
• Watch for symptoms: 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 were at the location at the listed date and time, you may have been exposed. Watch for symptoms for 21 days after exposure. Monitoring for symptoms is especially critical for people who have not been vaccinated with the MMR vaccine, particularly infants under one year of age who are not routinely recommended for the vaccine. If you develop symptoms, call CDPHE (720-653-3369) or your local public health agency right away.
• Call before you go: If you need medical care, do not delay. 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.
