SALT LAKE CITY — Utah is already reporting 42 measles cases this year, for a total of 237 cases during the current outbreak.
The Utah Department of Health and Human Services updated its measles statistics on Tuesday. The report shows 54 newly identified cases in the last three weeks.
The number of new cases each week has been decreasing since the final week of 2025, when there were 30 new cases — but the department could still add cases that are identified later to those counts.
In the last two weeks, Salt Lake County reported 12 new cases and 11 new cases were reported in both the southwest Utah health district and the Utah County Health District.
The most recent samples of wastewater detected measles in Salt Lake, Utah, Weber and Morgan counties, as well as in the southwest Utah health district. No recent measles detections were found in wastewater samples in Tooele County, Davis County, Summit County and the TriCounty health district.
Exposure locations in the last two weeks include Instacare locations in Spanish Fork, West Valley, Draper, and Riverton; two events at the Potter's House Christian Center and the emergency department at Intermountain Medical Center. Each exposure has specific dates and times listed on the department's website.
The health department invites anyone who was at one of the exposure locations during the exposure period to take an anonymous survey, available in English and Spanish, to learn about their risk and recommended next steps.
The department said that although it is rare for vaccinated people to get measles, it is still reasonable for those who were at an exposure location to watch for symptoms. However, a breakthrough infection typically causes mild illness that is less likely to spread.
Close to 89% of Utah's cases were people who were not vaccinated, where an additional 3% were from people with an unknown vaccination status.
The health department said it strongly encourages parents to talk to their health care provider about getting a measles vaccine, the MMR vaccine, for their children, even if they have not been exposed. This includes possible extra early doses for infants between 6 and 12 months, especially those traveling or going to areas where there is active spread, and an early second dose for children under 4.
Typically, measles vaccinations are administered at 12-15 months and again at 4-6 years.
About 61% of the cases in Utah's current outbreak were children under 18. Just under 9% of the 237 total cases have resulted in admission to a hospital.
The Utah Department of Health and Human Services encouraged people who think they or their child may have measles to stay home and away from others, call a clinic or provider ahead of time to prevent exposure in the waiting area.
It said people with measles symptoms should seek medical care if they have a hard time breathing or a fever that won't come down.
