SALT LAKE CITY – Several people were exposed to and infected with measles after attending an event at Soldier Hollow, the Utah Department of Health & Human Services confirmed Tuesday.

On Aug. 16, the Utah DHHS reported that approximately 2,000 people attended a Utah High School Cycling League event at Soldier Hollow. The department said it “has confirmed that several people were exposed to and infected with measles,” but did not disclose how many people, or the origin of the spread.

“Measles is highly contagious and spreads easily, even at outdoor events,” Dr. Leisha Nolen, epidemiologist for the State of Utah, said in a release from the department.

Nolen advised that attendees and participants of upcoming cycling league events check their MMR vaccination status to prevent measles.

The department said it is working to inform people of possible exposure.

Utah public health is working with the Utah High School Cycling League to inform families of race participants who attended the Soldier Hollow event on August 16, 2025. We are also working collaboratively to help prevent spread at ongoing practices and upcoming events.

Measles symptoms

The Utah HHS said symptoms usually begin within one or two weeks after initial exposure. Those symptoms can include:

• Mild to moderate fever with a cough that later spikes,
• runny nose,
• red, watery eyes,
• blotchy rash appearing first along the hairline and behind the ears.

The department advised that if you develop symptoms, it’s important to protect others from exposure by staying away from other people and calling your healthcare provider before going to a clinic or hospital.
