Data Notes for the Week of November 24

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 November 7—November 20.

Cases were stable during this 14-day period with an average of 155 cases per day.

On average, 79 out of the 155 cases each day were among people who are not vaccinated. The number of people hospitalized with COVID in Dane County hospitals increased, with an average of 84 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 4.6% and an average of 3,356 tests were conducted per day. Percent positivity has been increasing in recent weeks and is nearing 5%, an indication that infections in our community are becoming more widespread. 8-11 year olds had the highest percent positivity among all age groups at 7.7%.

397 cases were linked to school clusters or facility investigations (18% of all cases), which is the most we’ve ever had during a two-week period.

A total of 38,915 booster or third doses were administered during this 14-day period.

33% of Dane County residents who have completed the initial vaccine series have received a booster or third dose, and 68% of residents ages 65+ who have completed the initial vaccine series have received a booster or third dose.

The Wisconsin Department of Health Services has not provided us with vaccination data for 5-11 year olds, so the vaccination data on the first two pages of the snapshot is for ages 12+ only. We are working with the Department of Health Services to try to obtain these data in a timely manner.

The age-adjusted case rate during this 14-day period among not fully vaccinated people was 4 times higher than the rate among fully vaccinated people.

The age-adjusted rate of cases during this 14-day period was 944.0 per 100,000 not fully vaccinated residents, which is 4.0 times higher than the rate of 233.2 per 100,000 fully vaccinated residents. Not fully vaccinated people ages 12-17 had a case rate of 1,079.7 per 100,000, which is 9.6 times higher than the case rate for fully vaccinated people ages 12-17, which is 112.2: the lowest rate among all age groups.
