South Carolina had been one of only nine U.S. states that had not yet imposed formal "stay at home" orders during the coronavirus outbreak and the last on the East Coast. Local orders had already been in place in parts of the state.
"Governor Henry McMaster has ordered all South Carolinians to remain at home or work unless visiting family, exercising, or obtaining essential goods or services," the South Carolina Emergency Management Division said on Twitter.
The remaining eight states that have not imposed statewide stay-at-home orders are Arkansas, Iowa, Nebraska, Oklahoma, North Dakota, South Dakota, Utah and Wyoming. Oklahoma, Utah and Wyoming have some local orders in place.
A total of 2,232 cases of COVID-19 and 48 deaths have been confirmed in South Carolina, according to the state department of health.
