record: On Saturday, April 17, 2021, the Missouri Department of Health and Senior Services (DHSS) noted on its dashboard that a database error had been identified that caused a person with both PCR-positive and antigen-response counts to be counted. Both probable and confirmed cases. This amendment removes 11,454 double-counted cases in the previous probable antigenic case according to the notation.
record: Beginning Monday, March 8, 2021, the Missouri Department of Health and Senior Services (DHSS) began posting county-level data showing “probable” COVID-19 cases detected by antigen test Using historical data from the DHSS dashboard, we reconfigured this graph to include that number in the total.
record: Missouri updated its data dashboard on September 28, 2020 to remove duplicate cases. This results in a decrease in the total number of cases which causes the daily count to reflect negative numbers.
