**As of June 11, 2026, the CDC has confirmed 2,073 measles cases in the United States, with 93% outbreak-associated and the large majority occurring among unvaccinated or unknown-status individuals.** This pace already approaches the full-year 2025 total of 2,288—the highest since 1991—driven by carryover transmission from 2025 outbreaks in states including South Carolina and Utah, plus 30 new outbreaks reported so far in 2026. Measles’ high basic reproduction number (R0 of 12–18) enables rapid spread in under-vaccinated communities, while summer travel increases importation risk from global endemic areas. Weekly CDC surveillance updates and state health department reports provide the primary data releases that could shift market-implied odds on whether 2026 will set a new record.
