Utah Measles Outbreak Slows to 6 Cases in 3 Weeks as Vaccinations Rise

Six new measles infections were reported in Utah over the past three weeks, a sharp slowdown in an outbreak that has sickened 707 people since June 2025.
58 cases in one week marked the March peak, but weekly infections have stayed below 10 since early May as vaccinations increased, schools closed for summer and warmer weather reduced spread.
27,000 more Utahns got vaccinated this year than last, and health officials said 86% of measles patients were unvaccinated; the two-dose MMR shot is 97% effective.
56 Utahns were hospitalized during the outbreak and about one-third of patients visited emergency rooms, while wastewater data still suggests some infections have gone unreported.
State officials say the outbreak may be nearing its end but are urging vaccinations before school resumes, warning measles can weaken immune memory and rarely cause fatal brain inflammation years later.
