Symptoms and Prevention

Measles is a highly contagious disease that begins with fever, cough, runny nose, and red eyes. A rash typically follows, starting on the face and spreading throughout the body. The best way to protect against measles is vaccination with the MMR vaccine.

If you have not received the MMR vaccine, you can still receive it within 72 hours of exposure to potentially prevent illness. In some cases, immunoglobulin given within six days of exposure may also be helpful.

What to Do If You Were Exposed

If you were at any of the listed locations during the specified times, monitor yourself for symptoms for 21 days. If symptoms develop, it is crucial to contact your healthcare provider, urgent care, or emergency department before going in, and inform them of potential measles exposure to help prevent further spread.

Monitoring for symptoms is especially important for individuals who have not been vaccinated, particularly infants under one year of age.

Measles Cases in Colorado and the U.S.

This is the second case of measles in a Colorado resident in 2026. The first case involved an unvaccinated child who was out-of-state during the infectious period, posing no risk of local transmission. However, Colorado recorded 36 measles cases in 2025, the highest total in decades, as the disease has resurged nationally. As of February 2026, nearly 1,000 measles cases have been reported nationwide, putting the country on track to exceed the 2,281 cases reported in 2025. CDPHE
