As of April 23, 2026, the Centers for Disease Control and Prevention (CDC) reports 1,792 confirmed measles cases in the United States for the year, including 10 among international visitors—a slowdown from earlier peaks, with just 7 new cases in the week prior amid 22 outbreaks affecting 93% of patients. Most cases (92%) occurred in unvaccinated individuals, concentrated in under-vaccinated communities in South Carolina (668 cases), Utah (425), Texas (180), Florida (134), and Arizona (74); 6% required hospitalization, with no deaths. This surge follows 2025's 2,288 cases, driven by imported virus and declining MMR coverage (92.5% among kindergarteners). Reporting lags mean the final April 30 tally awaits the next CDC weekly update, expected soon, capturing rash-onset cases through month-end.
