Colorado health officials identify 2 additional measles cases in Weld County, possible exposure in El Paso County

Two additional cases of measles have been confirmed in Weld County. According to the Colorado Department of Public Health and Environment and Weld County Public Health, the new cases are in two unvaccinated adults.

Health officials said both people are household contacts of a previously confirmed case that is not linked to the Broomfield schools outbreak. However, officials said they are notifying the public about a potential exposure location in El Paso County related to those cases. Health officials told CBS Colorado last month that the outbreak at the schools had forced 80 students, staff and volunteers to stay away from the campuses due to their vaccination status.   

CDPHE said the known exposure location is the Chick-fil-A at the Citadel Crossing Shopping Center located at 505 N. Academy Blvd. in Colorado Springs, March 25 between 5 p.m. and 8 p.m. Symptoms may occur through April 15. 

CDPHE said while the measles, mumps, and rubella 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.

What to do if you were exposed

• 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.
