When Iowa 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.
On December 13, 2020, Iowa’s Total antigen tests (people) decreased by 77 and their Negative antigen tests (people) decreased by 206 without explanation.
On October 16, 2020, Iowa removed 12,831 tests from the state’s PCR test total. On the same day, 19,308 tests were added to the state’s antigen test total. We were unable to locate an official explanation, but these changes were likely the result of data cleaning and reorganization work.
On September 26, 2020, Iowa announced that due to a data update, roughly 27,000 antigen tests from long-term care facilities will be added to their COVID-19 antigen test data. This update will occur from September 26, 2020 to September 27, 2020, and will result in an increased number of antigen test tests reported in our data for Iowa. (Antigen data is available in our CSVs and API.)
As of May 19, 2020, Iowa reports PCR and antibody tests separately.
