Coronavirus cases in Dane County have been increasing rapidly over the past several weeks. This map details the increase in case counts in each neighborhood during that time. This is an update to the spreadsheets we published on July 3 and on June 30 and the maps we have published weekly since early July. The new map reflects a 30-day period from August 3 through September 2.
Several areas have seen rapid increases in cases in just the past two weeks, so this week we are reporting case counts at two-week intervals, including cases as of August 3, August 17 and September 2.
The data comes from the state Department of Health Services map, which shows current case counts by census tract. The DHS map does not show historical data, however. We are able to provide comparisons between past and current case counts because we’ve been tracking cases in each neighborhood since early May.
Each pin on the map represents a census tract. You can zoom in on the map to find your neighborhood. Clicking or tapping on a pin will allow you to see:
- Description of the neighborhood
- Number of cases as of 8/3
- Number of cases as of 8/17
- Number of cases as of 9/2
- Difference in the number of cases between those two dates
- Number of cases per 1,000 residents as of 8/3
- Number of cases per 1,000 residents as of 9/2
- Difference in the number of cases per 1,000 residents between those two dates
- The percentage change between those two dates
Many cases diagnosed within the past 30 days are considered active according to state Department of Health Services criteria. The difference in cases between July 27 and August 26 is the approximate number of active cases in each census tract.
We will update the data in this map at least once per week.
