Key Points

  • 142 new measles cases confirmed since March 10

Full Details

Utah health officials have confirmed 142 new measles cases since March 10, marking the largest weekly surge since the state's outbreak began last summer. The rolling three-week case count reflects a surge of more than 30% compared to last week's tally. Utah is now the nation's measles epicenter, accounting for nearly half of the nation's new cases last week, according to the CDC. Measles symptoms typically appear one to three weeks after exposure to the highly-contagious disease, meaning people who had contact with those new patients may be infected but not yet know it. This delayed symptom onset creates significant challenges for contact tracing and containment efforts.

Why It Matters

The outbreak's acceleration in Utah highlights the critical importance of maintaining high vaccination coverage (95%+) to achieve herd immunity and prevent measles spread.
