Data Notes for the Week of November 4

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 18—October 31.

Cases were stable during this 14-day period with an average of 87 cases per day.

Of the 87 cases per day, on average 42 per day were not vaccinated. The number of people hospitalized with COVID in Dane County hospitals was stable, with an average of 74 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 3,179 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.

68,810 people have received a booster dose or third dose.

During the snapshot period, an average of 265 people per day received a first or second dose (initial series.) An average of 2,230 people per day received a booster or third dose. There were 31,220 booster/third doses administered to Dane County residents during this 14-day period. A total of 68,810 booster/third doses have been administered to Dane County residents from 8/13/21-10/31/21, which is 17.5% of the fully vaccinated population.

*8/13 was the day third doses were first approved for people who are immunocompromised.

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

Over the past four weeks, cases have decreased among ages 8-11, 12-17, 18-22, 30-39, 40-49, and 70-79 and have been stable among all other age groups.

74.8% of all Dane County residents have received at least one dose of vaccine and 71.8% have completed the vaccine series. 86.4% of the eligible population (ages 12+) have received at least one dose of vaccine and 83.0% have completed the series. Beginning next week, we will be including ages 5-11 in the eligible population for vaccination data.

The age-adjusted case rate among not fully vaccinated people was 5.4 times higher than the rate among fully vaccinated people.

The age-adjusted rate of cases during this 14-day period was 767.0 per 100,000 not fully vaccinated residents, which is 5.4 times higher than the rate of 142.6 per 100,000 fully vaccinated residents. Not fully vaccinated people ages 65+ had a case rate of 912.8 per 100,000, which is the highest rate among all age groups and 7.5 times higher than the case rate for fully vaccinated people ages 65+, which is 121.7.
