Masks work, says the state epidemiologist

DHEC has new data that show mask laws help slow the spread of COVID-19. As of this week, according to the state’s health agency, nearly 40%, or about two million South Carolinians, live in jurisdictions that have local mask requirements.  Those jurisdictions with mask requirements have seen an overall decrease of 15.1% of total cases for the four weeks after the requirements were implemented, according to the data.
