Summary
2,318 measles cases were recorded in the United States in the first seven months of 2026, already exceeding all of 2025 and marking the worst year since 1991.
92.5% of children received the MMR vaccine last year, down from 95.2% in 2019 and below the 95% level needed to prevent outbreaks.
93% of infected people were unvaccinated, and epidemiologists say the true case count is likely higher because some sick people do not report infections.
The surge threatens the U.S. measles-elimination status won in 2000, with that designation expected to be revoked in November if domestic transmission continues.
