Data are updated Mondays, Wednesdays, and Fridays at 12:30pm. If we experience a delay in receiving data files, data will be updated at 4:30pm or as soon as we are able. Please check the timestamp on the landing page to determine when the dashboard was last updated. The dashboard will not be updated on observed holidays. Please see the Wisconsin Department of Health Services dashboard on those dates to see data.
Once a month we share a data snapshot that highlights a few key data points and updates our progress. The snapshot is published on the first Thursday on or after the 15th of the month. We also publish a blog post called "Data Notes" with the takeaway summary points from each snapshot. Subscribe to receive an email when a new blog is posted. Read past blog posts.

To better understand the spread of COVID-19 in Wisconsin, several state and local partners are working together to test samples of wastewater and look for the virus that causes COVID-19. This type of data collection can provide a way to monitor COVID that does not rely on individual reported tests.
- We include local wastewater data for Madison and Sun Prairie in our monthly data snapshots.
- You can see data for all participating cities on the state health department's website.

The numbers presented on this local dashboard may not match the numbers presented for Dane County on the DHS COVID-19 data pages. This can be due to timing of when data are posted, or the way we assign dates to cases and tests. DHS often uses the earliest date of either symptom onset or test specimen collected date as the date a case is counted. We use the date of test result, as this is the date the person is known to have COVID-19.
