Greenwood County added 155 confirmed cases of COVID-19 on Friday, doubling its previous single-day record as South Carolina approached 5,000 new cases amid a winter surge of the fast-spreading respiratory virus.

Friday's announcement represents the test results and deaths reported to the state on Wednesday.

Greenwood County added 155 confirmed cases of COVID-19, Laurens County recorded 78, Abbeville County saw 18, Saluda County logged 15 and McCormick County had 11.

This brings South Carolina's number of confirmed cases to 315,353, probable cases to 28,823, confirmed deaths to 5,217 and probable deaths to 478.

More than 80% of hospital beds are filled across the state, with 1,046 (11.7%) of those patients being treated for COVID-19. Of those, 261 patients are in ICU and 111 are on ventilators.

A confirmed case is an individual who had a confirmatory viral test performed by way of a throat or nose swab and that specimen tested positive for SARS-CoV-2, which is the virus that causes COVID-19, DHEC reports. A positive viral test, also called a PCR test or molecular test, alone is enough to classify a confirmed case.

DHEC reports a probable case is an individual who has not had a confirmatory viral test performed but has:

1. epidemiologic evidence and clinical evidence of infection, or

2. a positive antigen test and either epidemiologic evidence or clinical evidence.

A confirmed death is said to be someone whose death is related to COVID-19 and who tested positive with a confirmatory viral test for COVID-19.

A probable death classification refers to an individual whose death certificate lists COVID-19 disease or SARS-CoV-2 as a cause of death or a significant condition contributing to death but did not undergo confirmatory viral testing.

Abbeville — 1,191 (21 deaths)

Who Should Get Tested?

If you are out and about in the community, around others, or not able to socially distance or wear a mask, DHEC recommends that you get tested at least once a month.

Routine testing allows public health workers to diagnose those who are asymptomatic and interrupt the ongoing spread of the virus. Learn more about who should get tested here: scdhec.gov/covid19/who-should-get-tested-covid-19.
