As of mid-June 2026, CDC data show 2,073 confirmed U.S. measles cases year-to-date—already approaching the full-year 2025 total of 2,288—driven by 30 new outbreaks and 93% of cases tied to sustained community transmission, primarily among unvaccinated or unknown-status individuals. Large clusters persisting from 2025, such as South Carolina’s outbreak exceeding 900 cases, reflect pockets of lower MMR coverage enabling rapid spread from imported introductions. Weekly CDC surveillance updates and potential summer travel-related imports remain key near-term variables, while any expansion of vaccination efforts or outbreak containment could moderate totals before year-end resolution.
