This page will be updated regularly as information becomes available. 

Testing

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.

Positive Cases Indicated by Heat Map

The 14-day Heat Map displays the most recent reported cases during the past 14-day period and estimates where the current burden is due to recently reported cases.

The heat map indicates reported cases of COVID-19 in the state. Regardless of the number of reported cases within an area, all South Carolinians should take seriously the recommended precautions for protecting against this disease. The cumulative Heat Map shows all historic reported cases of COVID-19.

Summary of COVID-19 Case Reports through September 26 and Projections through October 17

Last updated September 28, 2020

Table 1 presents numbers of COVID-19 cases observed in the ‘Sunday through Saturday’ weeks since March 1 as well as projections of COVID-19 cases through to the week of October 11 – October 17. 

For each week, data are presented regarding the number of new cases, the overall number of cases up to that time, the case rate per 100,000 persons up to that point, and an indication regarding whether the numbers were observed (i.e. confirmed cases reported to DHEC) or have been projected.

Projections Table 1 - 9.28.2020

 

Table 2 below provides additional perspectives regarding the projected case rate of 2,973 per 100,000 in SC on October 17, by comparing it to case rates already observed as of September 26 in those states that have suffered the greatest burden of COVID-19.

Additional Notes and Explanations

  1. Regarding table 2, it's also important to note that uncertainties exist regarding projections made for the coming weeks. For example, since not all persons who are infected are tested, the number of officially reported cases is not identical to the actual number of cases in the population.
  2. The modeling and projections shown below come from the Institute for Health Metrics and Evaluation (IHME), which offers one of the most commonly used models. Predictions made by different models may typically differ as each may depend on slightly different assumptions and use of data. Though the predictions regarding future weeks and months do not match perfectly, they generally provide helpful perspectives regarding the future course of the pandemic.

 

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.
