CDC Reports Over 5,000 Measles Cases in US, Highest in 35 Years

The Centers for Disease Control and Prevention (CDC) has recorded 5,182 measles cases in the U.S. in 2026, marking the highest number since 1991. Cases have been reported across 45 states and D.C., with children and teenagers accounting for nearly 60% of confirmed infections. This surge is attributed to declining vaccination rates, with coverage among U.S. kindergarteners decreasing to 92.4% in the 2025-2026 school year. Multiple states are experiencing sustained outbreaks, and several measles-related deaths have been reported.
