SC Testing Data & Projections (COVID-19)

Sunday, October 25, 2020, 11:30 a.m. 
This page will be updated regularly as information becomes available. 


DHEC's Public Health Laboratory receives samples from healthcare providers to be tested for COVID-19. The U.S. Food and Drug Administration (FDA) has approved some private labs to also conduct testing for COVID-19. These labs are required to report positive and negative test results for South Carolina residents to DHEC within 24 hours. Numerical, graphic and mapping summaries regarding testing and the number of observed and projected cases in South Carolina are shown below. Additional details concerning the distribution of cases can be found on the County-Level Data for COVID-19 page.


Starting Saturday September 19, the testing table data can be found on the County-Level Dashboard under the Testing tab.



COVID-19 Deaths in South Carolina Over the Previous 60 Days, by Date of Death

To clearly provide the actual dates of COVID-19-related deaths, DHEC updates daily this graph representing COVID-19 Deaths in South Carolina by Date of Death. This data visualization provides the date that COVID-19 deaths occurred, not the day they were announced, as there can sometimes be a delay in when a death occurred to when it is confirmed and reported publicly. For better visibility, this graph has been updated to show the previous 60 days.

References for Modeling and Projecting COVID-19 Cases, Deaths and Hospitalizations

The Centers for Disease Control and Prevention (CDC) has compiled predictive modeling resources for use by the public that provide information for forecasting COVID-19 cases, hospitalizations and deaths. There are various methods for developing models and projections. Learn more and access the CDC resource here.

Beginning Oct. 12, two projection charts previously included on this page—Observed and Projected SC COVID-19 Cases by Week and South Carolina’s Projected Case Rates per 100,000 Compared, Selected Severely Impacted States—and the Institute for Health Metrics and Evaluation's projections are replaced by the Centers for Disease Control and Prevention (CDC) forecasting for COVID-19 cases, hospitalizations and deaths, as follows:

Using a single source for projection data—the CDC—instead of comparing the two DHEC-developed projection charts and the IHME-developed projections provides a more comprehensive overview and more accurate comparisons.
