Data Notes for the Week of December 16

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 29—December 12.

Data are incomplete this week.

We are presenting an abbreviated snapshot this week because we are experiencing a delay in processing positive test results in the Wisconsin Electronic Disease Surveillance System (WEDSS) due to last week's data processing delays from the Wisconsin Department of Health Services and a high number of positive tests. We are rapidly working to resolve this issue in order to present the most accurate, timely data.

Data on our dashboard, including case counts, 2 week trend in cases, and percent positivity, are similarly affected. Please see our dashboard page for an alert related to these issues.

The Omicron variant has been detected in Dane County.

The best protection against COVID-19, including the Omicron variant, is for people ages 5 and older to get vaccinated and people ages 16 and older to get a booster dose when eligible.

See the full news release for details.

In November 2021, a person not fully vaccinated in Dane County was 27 times more likely to test positive for COVID and 46 times more likely to be hospitalized for COVID than a person fully vaccinated with a booster or additional dose.

A person vaccinated with the initial series only was 9 times more likely to test positive for COVID and 7 times more likely to be hospitalized for COVID than a person fully vaccinated with a booster or additional dose. This emphasizes the importance of getting a booster if you’re eligible. There were no deaths among people diagnosed with COVID in November who were fully vaccinated with a booster or additional dose.

45.2% of fully vaccinated people in Dane County have gotten a booster or additional dose.

This percentage is 49.7% for people ages 16+, and 77.5% for people ages 65+.

This week, we received vaccination data for 5-11 year olds from the Wisconsin Department of Health Services for the first time since 5-11 year olds became eligible for vaccination. 46.0% of children ages 5-11 in Dane County have received at least one dose of vaccine, and 33.8% have completed the series.
