Utah sees sustained decline in measles cases over three weeks
8 articles · Updated · KSL.com · Apr 24
Only four new measles cases were reported statewide last week, with 607 total since June 2025 and nearly 50 hospitalizations.
State epidemiologist Dr. Leisha Nolen attributes the decline to increased vaccinations—such as a fourfold rise in Vernal—and warmer weather, though risks remain, especially in unvaccinated communities.
Utah’s outbreak has affected 24 of 29 counties and lasted longer than recent outbreaks in Texas and South Carolina, prompting ongoing public health efforts and continued recommendations for early childhood vaccinations.

Utah’s Measles Outbreak: 607 Cases, 49 Hospitalizations, and the Fight to Reach 95% Vaccination Coverage
Overview
Utah's measles outbreak, which peaked at around 600 cases, has shown a promising decline following intensified public health efforts starting in March 2026. A 31% rise in MMR vaccinations, early extra doses for infants, and targeted containment in schools helped reduce new infections from 116 to 43 cases within weeks. Despite these gains, vaccination coverage remains below the 95% needed for herd immunity, with an 11% exemption rate fueling ongoing vulnerability. Hospitalizations and emergency visits strained healthcare systems, but the recent drop in cases is easing this burden. To prevent resurgence, Utah is advancing catch-up vaccinations, travel advisories, and combating misinformation to close immunity gaps and sustain control over measles.
