Duplicate tests on same individual not included. Used total cases and total persons tested on DOH website (includes sentinel & surveillance samples). Only positive cases available on 8/25- 8/27/20. Antigen tests added on 10/7/20 and included past tests so test positivity not calculated for 10/7/20. The rate of positivity provides insight into whether enough testing is being conducted. If positivity is high, it suggests that the sickest are being tested and milder or asymptomatic cases may be missed. The WHO has said that in countries that have extensive testing for COVID-19, percent positive should remain at 5% or lower for at least 14 days. https://doh.sd.gov/news/Coronavirus.aspx https://coronavirus.jhu.edu/testing
