South Carolina average daily new cases

The chart below shows the trend of new case discovery for South Carolina. Flattening the curve of new daily cases will help alleviate the burden on hospitals and healthcare workers and help ensure that patients that need critical care can get it.

Note: If testing is insufficient the above curve will underrepresent true case discovery. Nationwide daily testing per million residents is currently 336.1. Reported South Carolina testing per million residents per day is 117.4. South Carolina testing may be underreported or insufficient relative to the US as a whole.

South Carolina average daily deaths

Deaths from COVID-19 are likely better reported than the true number of positive cases. As a result, the trend in average daily deaths from COVID-19 might be a more telling measure of progression through the outbreak than daily average positive cases.

COVID-19 testing statistics in South Carolina

Testing metrics for South Carolina are too low for me to have faith that they are being accurately reported. I'm only reporting testing statistics for states with an A data grade from the COVID Tracking Project that test at a rate of at least 100 per million residents per day. South Carolina is either not testing at that level or is not reporting their testing fully.

A final word on this analysis

In order to manage the outbreak, states need to increase their testing capacity. As testing increases, the number of detections as a fraction of total tests (positive rate) should hopefully decrease over time. If a state is able to test widely enough (at least 300 tests daily per million residents, probably more) to drive the positive rate down (less than 5%) there may be the potential to manage a regional outbreak with isolation, contact tracing and quarantine South Korea has.

Please take my calculations and amatuer epidemiological speculations with a huge grain of salt as I'm moving quickly to get what I hope are meaningful measures online. There may be errors in my data and my thinking!

These statistics were inspired by posts on Calculated Risk and the Bondad Blog regarding metrics to track for COVID-19.

Last but not least, thanks to the folks at COVID Tracking Project for making this data available to everyone.
