You can find past issues on our data and dashboard page. The data below are from January 3-January16.

The WI Department of Health Services (DHS) has implemented a new process to auto-import positive test results from the “staging” area in the statewide data system, WEDSS. Before this new process, we included cases from staging in our case counts, but DHS did not, causing a discrepancy between the two. We assign cases to the date of their positive test result, while DHS assigns cases to the date they were processed out of staging. Therefore, DHS, and other sources who use their data will show more elevated case numbers for Dane County over the past week than what our data shows, and lower case numbers for the couple of weeks before that. Going forward, our case counts should much more closely match what DHS reports.


Cases were high but stable during this 14-day period with an average of 1,407 cases per day.

The number of people hospitalized with COVID in Dane County hospitals was also high but stable with an average of 190 people hospitalized each day. Percent positivity was 20.6% and an average of 6,830 tests were conducted per day.

A high percent positivity means we are likely missing cases in our case counts. If you need a test, same day appointments are often available at the Alliant Energy Center. Visit our testing page to make an appointment and pre-register.
