Utah health officials are monitoring a significant measles outbreak, with 711 total Utah residents diagnosed during this outbreak to date. Recent data shows that 514 residents have been diagnosed with measles in 2026 so far, compared to 197 diagnoses recorded in 2025.
In the last three weeks, there have been six reported cases of measles in the state.
Public health officials in Utah are investigating reported cases to identify individuals at risk and any locations where possible exposures may have occurred. As of July 17, 2026, no new exposure locations had been reported to the Utah Department of Health and Human Services.
The measles virus can remain in the air for up to two hours after an infected person has visited a location. Officials advise that even without a confirmed exposure, individuals should monitor for symptoms for 21 days if they believe they have been around someone with measles.
Wastewater testing is being used to track the presence of the virus. When measles is detected in wastewater, it indicates that one or more people in or traveling through that area are shedding the virus, though results do not specify the exact number of infected individuals.
Symptoms of measles include high fever, cough, runny nose, red watery eyes, and a rash. Potential complications include pneumonia, encephalitis, hospitalization, and death.
