Measles Update in Utah
SALT LAKE CITY — This year, Utah has reported 42 measles cases, bringing the total to 237 during the ongoing outbreak.
The Utah Department of Health and Human Services provided the latest figures on Tuesday, revealing 54 new cases identified over the past three weeks.
While the number of new cases has been declining since the last week of 2025, when 30 were reported, it’s possible that more cases may be added to the total as they are discovered later.
In the past two weeks, Salt Lake County has seen 12 new cases, while both the southwest Utah health district and the Utah County Health District reported 11 new cases each.
Recent wastewater samples showed traces of measles in Salt Lake, Utah, Weber, and Morgan counties, as well as in the southwest Utah health district. However, no measles was detected in Tooele County, Davis County, Summit County, or the TriCounty health district.
Locations of potential exposure over the last two weeks include Instacare sites in Spanish Fork, West Valley, Draper, and Riverton; events at the Potter’s House Christian Center; and the emergency department at Intermountain Medical Center. Specific dates and times for these exposures are available on the department’s website.
The health department is encouraging anyone who visited these exposure sites during the relevant times to complete an anonymous survey, which is available in both English and Spanish, to assess their risk and understand recommended next steps.
Although it’s uncommon for vaccinated individuals to contract measles, the department advises those who may have been exposed to monitor for symptoms. Breakthrough infections generally lead to milder illnesses that are less likely to spread.
Nearly 89% of the cases in Utah are among unvaccinated individuals, with an additional 3% from those with unknown vaccination status.
Parents are urged by the health department to consult their healthcare providers about the measles, mumps, and rubella (MMR) vaccine for their children, even if there hasn’t been any known exposure. Additional early doses for infants aged 6 to 12 months—especially those traveling or in regions with active outbreaks—and an early second dose for children under 4 might be considered.
Measles vaccinations are usually given at ages 12-15 months and again at 4-6 years.
About 61% of the reported cases in this outbreak involve children under 18, and just under 9% of the 237 cases have needed hospitalization.
The Utah Department of Health and Human Services advises individuals who suspect they or their child may have measles to remain at home and avoid contact with others, and to call a medical provider beforehand to prevent exposure in waiting areas.
If experiencing difficulty breathing or a persistent high fever, those with symptoms should seek medical attention.
