As of May 7, 2026, the Centers for Disease Control and Prevention (CDC) reports 1,842 confirmed measles cases across the United States this year—the largest outbreak in over three decades—primarily in unvaccinated individuals (92% of cases) amid declining childhood MMR vaccination coverage below the 95% herd immunity threshold in affected communities. Major hotspots include South Carolina (669 cases), Utah (439), Texas (182), Florida (135), and Arizona (78), with transmission fueled by imported cases and close-knit under-vaccinated groups. Recent CDC data shows a slowing pace from earlier surges, but risks persist through year-end; watch weekly Thursday updates and potential review of U.S. measles elimination status for shifts in epidemiological trends.
