Data Quality Notes

On August 1, 2023, we identified a data reporting issue from one health system. We are working with the health system to correct the numbers. Once we receive accurate numbers, we anticipate the hospitalization numbers from October 1, 2022 to August 1, 2023 will be lower than currently presented. We will post an update when we have one.

Comparison to Wisconsin Department of Health Services (DHS) Data

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.
