South Carolina Overview
When South Carolina reports no data, several days of data, or unusual data (such as decreases in values that should increase), our volunteers note it here on the date the anomaly occurred. We also note here changes in our own methodology that affect the data.
Negative test results reported in our API and CSVs are calculated by subtracting Confirmed cases from Total PCR tests (specimens) in the absence of better data.
On January 11, 2021 through January 15, 2021, South Carolina experienced an internal systems issue which has resulted in data missing from their dashboard. We urge caution when interpreting their data from this period, and encourage the use of 7 and 14-day averages as more reliable figures than individual metrics.
On December 21, 2020, South Carolina announced via the official South Carolina Public Health and Environmental Protection Agency twitter, that there would be no update to their data on December 25, 2020, or on January 1, 2021 due to the holidays. Additionally, they noted that the data for December 26, 2020 and January 2, 2021 would each include two days of data.
On December 20, 2020, South Carolina noted that their Currently hospitalized figure was larger than normal due to an error in facilities reporting. Their Currently hospitalized increased from 1461 to 1471.
On November 25, 2020, South Carolina announced via the official South Carolina Department of Health and Environmental Control twitter that there would be no update to their data on November 26, 2020.
On September 15, 2020, South Carolina started reporting antigen testing data, reporting 7,763 positive tests and 23,477 total tests. Its “viral (i.e. molecular/PCR) tests” positives and totals dropped by about the same amount, likely due to the removal of this data.
Between August 25 and September 21, 2020, South Carolina did not provide updated estimates of the number of Recovered cases.
On September 10, 2020, South Carolina announced that it added a large number of saliva tests from the University of South Carolina to its data, causing an unusually large number of cases in the data for September 11.
On August 23, 2020, South Carolina corrected a double-counting of testing numbers from the months May–August. This resulted in a significant drop of all aspects of testing-related counts, with Total PCR tests (specimens) dropping by approximately 22,000 and total antibody tests dropping by 1,500.
On August 14, 2020, South Carolina reported an unusually large number of tests without explanation.
On July 18, 2020, South Carolina announced it was transitioning to new reporting systems and that "there may be incomplete data with significant gaps." Though reporting resumed July 28, 2020, this resulted in data being carried over at times. We will backfill with the updated numbers when they are available.
As of June 11, 2020, South Carolina reports PCR tests separately from antibody tests. Total test numbers were reduced by around 22,000 as a result of this change.
