As of April 1, 2026, Utah has confirmed 559 measles cases since the outbreak began in June 2025. In the past week, 73 new cases were identified, underscoring the virus's rapid spread. The Southwest Utah Health District reports the highest number of cases with 242, followed by Utah County at 87 and Salt Lake County at 60. Several public locations, including schools and grocery stores, have been identified as potential exposure sites.
Health officials are urging individuals who may have been exposed to monitor for measles symptoms for at least three weeks. Measles is a highly contagious airborne virus, with symptoms typically appearing about a week after infection. Common signs include high fever, cough, a rash, and white spots inside the mouth. Serious complications can arise, especially for the unvaccinated, including pneumonia, encephalitis, seizures, and even death.
The Department of Health and Human Services reports that while 90% of Utahns are vaccinated, immunization rates among kindergarteners have decreased since 2014. Health experts stress that vaccination is the most effective means of prevention and encourage those who are not vaccinated to receive the MMR vaccine. The CDC notes a national increase in measles cases and outbreaks in 2026 and 2025 compared to previous years.
