Data Notes for the Week of November 18

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 1—November 14.

Cases increased during this 14-day period with an average of 137.5 cases per day.

On average, 68 out of the 137.5 cases each day were among people who are not vaccinated. The number of people hospitalized with COVID in Dane County hospitals was stable, with an average of 77 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 4.1% and an average of 3,338 tests were conducted per day. Percent positivity has been increasing in recent weeks. However, as it remains under 5%, this is a good indication that we’re testing at the level we need to in order to find cases.

We have not received updated vaccination data since 11/5 due to data reporting errors experienced by the Wisconsin Department of Health Services, so the vaccination data on pages 1 and 2 has not been updated since the 11/4 data snapshot. We are also unable to provide an updated number of booster/third doses or doses administered to 5-11 year olds. We anticipate being able to provide these data in next week’s snapshot, which will be released on Wednesday due to the Thanksgiving holiday. Nationally, roughly 10% of 5-11 year olds in the U.S. have received at least one dose of vaccine.

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

Over the past four weeks, cases have increased among most age groups, including ages 0-4, 5-7, 8-11, 12-17, 18-22, 23-29, 30-39, 40-49, 50-59, and 60-69. Cases were stable among ages 70-79, 80-89, and 90+.

In October, not fully vaccinated people were 6 times more likely to test positive for COVID, 39 times more likely to be hospitalized for COVID, and 13 times more likely to die from COVID.

· The age-adjusted case rate in October was 364.6 per 100,000 fully vaccinated people and 2,276.7 per 100,000 not fully vaccinated people. (6 times greater for not fully vaccinated people).

· The age-adjusted hospitalization rate in October was 6.8 per 100,000 fully vaccinated people and 269.6 per 100,000 not fully vaccinated people (39 times greater for not fully vaccinated people).

· The age-adjusted death rate in October was 0.5 per 100,000 fully vaccinated people and 6.4 per 100,000 not fully vaccinated people (13 times greater for not fully vaccinated people).

The age-adjusted case rate during this 14-day period among not fully vaccinated people was 8.2 times higher than the rate among fully vaccinated people.

The age-adjusted rate of cases during this 14-day period was 1,736.2 per 100,000 not fully vaccinated residents, which is 8.2 times higher than the rate of 210.6 per 100,000 fully vaccinated residents. Not fully vaccinated people ages 12-17 had a case rate of 918.5 per 100,000, which is 14.1 times higher than the case rate for fully vaccinated people ages 12-17, which is 65.1: the lowest rate among all age groups.
