South Carolina tops Texas measles outbreak record—with no end in sight

The explosive measles outbreak in South Carolina has now reached 789 cases, breaking Texas's outbreak record last year of 762 cases, which at the time was the largest outbreak in the US since measles was declared eliminated from the US in 2000. The country is at grave risk of losing its elimination status in the coming months due to continuous spread.

With Texas' outbreak last year—which spanned January to August and spread to additional states—the US saw the largest measles case total since 1991, with 2,255 confirmed cases. Now, with South Carolina's unbridled outbreak, 2026 is already looking like it will be another record year.
