South Carolina reported a surge to 789 measles cases on Tuesday, state health data showed, overtaking Texass 2025 tally of 762 infections and marking the biggest state-level outbreak in the country this year.
The latest count includes 89 new cases since Friday, as officials warned the widening outbreak could continue for weeks or months amid lagging vaccine uptake.
The outbreak, which began in October, has been centred in the northwest part of the state, which includes Greenville and Spartanburg, according to the South Carolina public health department.
