This data set contains Wisconsin COVID-19 case, death, hospitalization, test data and population information by county boundary. All data are laboratory-confirmed cases of COVID-19 that are frozen once a day to verify and ensure that we are reporting accurate information. These numbers are the official state numbers, though counties may report their own totals independent of Department of Health Services (combining the DHS and local totals may result in inaccurate totals). Deaths are reported by health care providers, medical examiners/coroners, and recorded by local health departments in order to be counted by the state DHS. Detailed data descriptions can be found within the COVID-19 Public Use Data Definitions document: https://www.dhs.wisconsin.gov/publications/p02677.pdf.
