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 22—December 5.

Cases increased during this 14-day period with an average of 188.5 cases per day.

On average, 102.5 out of the 188.5 cases each day were among people who are not vaccinated. The number of people hospitalized with COVID in Dane County hospitals was high but stable, with an average of 114 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 5.5% and an average of 3,376 tests were conducted per day. Percent positivity has been increasing in recent weeks and is over 5%, an indication that infections in our community are becoming more widespread.

Roughly half of 5-11 year olds in Dane County have received at least one dose of COVID-19 vaccine.

 Data are preliminary pending more info from the Wisconsin Department of Health Services (DHS), and 5-11 year olds are still not included in the vaccination data on pages 1 and 2 of this snapshot. We hope to be able to include all data for 5-11 year olds next week.

42.3% of fully vaccinated people in Dane County have gotten a booster or additional dose.

This percentage is 45.6% for people ages 18+, and 75.7% for people ages 65+. People ages 65+ with a booster or additional dose have the lowest case rates out of all Dane County residents.

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

Case rates among Dane County residents are significantly lower than case rates in Wisconsin for ages 18-24, 25-44, 45-64, and 65+. Overall, Wisconsin’s most recent 7-day average case rate is 1.7 times higher than Dane County’s.

The age-adjusted case rate during this 14-day period among not fully vaccinated people was 26.6 times higher than the rate among people with a booster or additional dose. 

The age-adjusted rate of cases during this 14-day period was 1,480.3 per 100,000 not fully vaccinated residents, which is 4.2 times higher than the rate of 350.1 per 100,000 people fully vaccinated with the initial series, and 26.6 times higher than the rate of 55.6 per 100,000 people fully vaccinated with a booster or additional dose. People vaccinated with the initial series only were 6.3 times more likely to test positive than people who received a booster or additional dose.

The Omicron variant has not been detected in Dane County.

Our blog post, released December 1, summarized the most recent information on Omicron we know right now. UW-Madison and the Wisconsin State Lab of Hygiene are working to sequence test samples here in Dane County so we can detect Omicron if it arrives. We recommend everyone get vaccinated, get a booster shot, and wear a mask in indoor public spaces to prevent the spread of COVID.
