U.S. measles cases hit 35‑year high in 2026

The U.S. Centers for Disease Control and Prevention confirmed 2,318 measles cases as of July 23, 2026, spread across 45 states and the District of Columbia. The total surpasses the 2,289 cases recorded for all of 2025, making 2026 the worst year since 1991. More than 90 % of infections occurred in unvaccinated individuals, primarily children and teenagers. Seven states account for most cases, with South Carolina (≈670) and Utah (≈522) together representing about half of the national tally, followed by Texas, Virginia and Pennsylvania.

No deaths have been reported this year, and hospitalizations have fallen compared with 2025. National measles‑M M R vaccination coverage remains around 93 %, but several states have rates below the 95 % threshold needed to prevent outbreaks. Public‑health experts, including Dr. William Moss of Johns Hopkins University, note that high vaccination coverage in places such as Maryland (96 % coverage, 12 imported cases) has prevented sustained community transmission.

Community organizations such as SOLN and PreCoHis have issued alerts to Dominican residents in the United States, urging vaccination amid the surge.
