As of June 11, 2026, the CDC reports 2,073 confirmed U.S. measles cases this year, already approaching the full-year 2025 total of 2,288 and far exceeding prior recent years. Sustained outbreaks—30 new ones reported so far, with 93% of cases linked to ongoing chains—drive the totals, fueled by 92% of patients being unvaccinated or having unknown status and pockets of MMR coverage below the 95% herd-immunity threshold. Importations via international travel continue seeding local transmission, though hospitalization rates sit at 6%. Weekly CDC surveillance updates and any shifts in state-level vaccination enforcement or outbreak containment will be the key near-term data releases influencing market-implied odds for final 2026 case counts.
