Data Notes for the Week of October 21

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 4—October 17.

Cases decreased during this 14-day period, with an average of 118 cases per day. 

This is down from 138 cases per day from last week’s snapshot. The number of people hospitalized with COVID in Dane County hospitals was stable, with an average of 85 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 3.4% and an average of 3,519 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. 

Dane County has consistently had lower case rates among all age groups than Wisconsin overall (with the exception of a recent spike among college-aged students). Cases among ages 0-4 decreased by 40% during this snapshot period, and cases among ages 18-22 decreased by 24%. All other ages remained stable.

74.4% of all Dane County residents have received at least one dose of vaccine and 71.7% have completed the vaccine series. 85.9% of the eligible population (ages 12+) have received at least one dose of vaccine and 82.8% have completed the series.

In September, not fully vaccinated people were 4 times more likely to test positive for COVID, 11 times more likely to be hospitalized for COVID, and 21 times more likely to die from COVID.

• The age-adjusted case rate in September was 444.7 per 100,000 fully vaccinated people and 1,981.6 per 100,000 not fully vaccinated people (4 times greater for not fully vaccinated people).
• The age-adjusted hospitalization rate in September was 6.7 per 100,000 fully vaccinated people and 71.2 per 100,000 not fully vaccinated people (11 times greater for not fully vaccinated people).

• The age-adjusted death rate in September was 0.8 per 100,000 fully vaccinated people and 16.5 per 100,000 not fully vaccinated people (21 times greater for not fully vaccinated people).
