Tooele County, Utah, confirmed its first case of measles on Monday, February 16, 2026, in a student at Stansbury High School. The student was exposed to the virus at a multi-district school event held outside of Tooele County, according to the Tooele County Health Department.
Health officials reported the student attended school while infectious on February 9 and 10, prior to the onset of symptoms. Parents of students potentially exposed have been directly notified, and guidance has been provided, the department stated.
The confirmation comes as Utah experiences a significant measles outbreak. As of Monday, the statewide case count reached 272, according to the Utah Department of Health and Human Services. Only the TriCounty area – encompassing Duchesne, Carbon, Daggett, and Uintah counties – has not reported a case.
Dr. Grant Sunada, Tooele County health officer, emphasized the importance of vaccination. “Getting vaccinated helps protect those who cannot receive the vaccine and are vulnerable,” he said. “Please reach out to your healthcare provider or our Health Department staff to see if you are up to date on your vaccines. We are available to talk through your questions about the best ways to keep you and your family healthy and safe.”
Symptoms of measles include fever, cough, runny nose, red, watery eyes, and a blotchy rash that typically begins on the face and spreads downward across the body. Health officials are urging anyone experiencing these symptoms, or who believes they may have been exposed, to contact their healthcare provider before seeking in-person care to prevent further spread.
The Tooele County Health Department is reminding residents of the effectiveness and safety of the Measles-Mumps-Rubella (MMR) vaccine. The department has not specified the nature of the multi-district school event where exposure occurred.
