An El Paso County child and an Arapahoe County adult have been diagnosed with measles in separate outbreaks, bringing the total number of cases in Colorado to 14 for the year, according to state health officials.

The El Paso County child, under 5 years old, recently traveled to Ontario, Canada, where a measles outbreak is ongoing. The child had received one dose of the measles, mumps, and rubella vaccine, but health officials recommend two doses for optimal protection.

The Arapahoe County adult was exposed to the measles virus at Denver International Airport by an infected out-of-state traveler. Seven other confirmed measles patients in Colorado also passed through the airport at the same time as the initial exposure.

The virus can linger in the air for up to two hours, posing a risk to individuals who may have been in the vicinity of the infected persons.

If you were at the following locations during specified times, watch for measles symptoms:

• Powers Pointe Urgent Care, Colorado Springs, on June 3
• HCA HealthONE Aurora Emergency Department, Aurora, on June 5
• Safeway, Aurora, on June 6
• St. Francis Medical Center Emergency Department, Colorado Springs, on June 7
• UCHealth University of Colorado Hospital Emergency Department, Aurora, on June 7

Individuals who develop symptoms should contact healthcare providers and explain possible measles exposure to receive prompt care and prevent further transmission.

Measles symptoms typically appear within one to three weeks of exposure and include fever, runny nose, red eyes, cough, and a red rash. Unvaccinated individuals can reduce infection risk by getting vaccinated within 72 hours of exposure.

Colorado has reported 14 measles cases in 2025, significantly higher than the usual annual count. For more information on exposure locations and symptoms, visit the Colorado Department of Public Health and Environment website.
