Data Notes for the Week of October 28

Read Data Snapshot    

If you’re new to the data snapshot, we publish a weekly summary of the status for each of our metrics (you can find past issues on our data and dashboard page). The data below are from October 11—October 24.

Cases decreased during this 14-day period with an average of 94 cases per day.

This is down from 118 cases per day during last week’s snapshot. The number of people hospitalized with COVID in Dane County hospitals was stable, with an average of 79 people hospitalized with COVID-19 in Dane County hospitals each day. We are not able to discern whether these hospitalizations are among Dane County residents or among patients transferred to the Dane County hospitals from the surrounding areas. Percent positivity was 2.8% and an average of 3,326 tests were conducted per day. Because percent positivity has been holding steady and has remained under 5%, this is a good indication that we’re testing at the level we need to in order to find cases.

Dane County currently has the lowest case rate and lowest percent positivity out of all 72 counties in the state.

Case rates among Dane County residents are lower than case rates in Wisconsin for each age group, and the difference is largest among ages 16-17; case rates among ages 16-17 are 2.6 times higher in Wisconsin overall than in Dane County. Almost all age groups saw a decrease over this snapshot period, including 0-4 year olds (42% decrease), 8-11 year olds (48% decrease), and 12-17 year olds (53% decrease). 5-7 year olds, 70-79 year olds, and 80+ year olds remained stable.  
 

74.4% of all Dane County residents have received at least one dose of vaccine and 71.8% have completed the vaccine series. 85.9% of the eligible population (ages 12+) have received at least one dose of vaccine and 82.9% have completed the series.

The age-adjusted case rate among not fully vaccinated people was 4.6 times higher than the rate among fully vaccinated people.

The age-adjusted rate of cases during this 14-day period was 709.6 per 100,000 not fully vaccinated residents, which is 4.6 times higher than the rate of 154.2 per 100,000 fully vaccinated residents. Not fully vaccinated youth ages 12-15 had a case rate of 526.1 per 100,000, which is 8.3 times higher than the case rate for fully vaccinated youth ages 12-15, which is 63.7: the lowest rate among all age groups.
