Data Notes for the Week of February 17

Read Data Snapshot

You can find past issues on our data and dashboard page. The data below are from January 31-February 13.

Cases decreased during this 14-day period with an average of 359 cases per day.

The number of people hospitalized with COVID in Dane County hospitals also decreased with an average of 111 people hospitalized each day. Percent positivity was 10.0% and an average of 3,599 tests were conducted per day.

Over the past four weeks, cases decreased among all age groups. People ages 0-4 and 18-22 currently have the highest case rates at 106 per 100,000 per day, and people ages 8-11 have the highest percent positivity at 15.7%. People ages 5-11 are also our lowest vaccinated group. If you or your child is not up to date on their shots, get vaccinated at a quick and free site near you.

62.1% of Dane County residents ages 5+ are up to date on their COVID vaccines.

20.9% are fully vaccinated but not up to date, 4.6% are partially vaccinated, and 12.4% are not vaccinated. “Up to date” means a person has received all recommended COVID vaccines, including any booster dose(s) when eligible, according to CDC’s recommendations. Are you up to date on your vaccine? If not, you can get vaccinated at a quick and free site near you.

There have been 3,450 reinfections among Dane County residents from October 2020 to January 2022, and over half of those were in January 2022 alone.

Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. Reinfections are roughly 3.3% of overall cases in Dane County over the past 16 months. 57.6% of all reinfections in Dane County occurred in January 2022. The Omicron variant has the ability to evade immunity from past infection or vaccination, so it’s not surprising that we’re experiencing a higher number of reinfections over the past couple of months.
 

Note: The Illness After Vaccination data with case, hospitalization, and death rates by vaccination status will be reported next week instead of this week due to the Wisconsin Department of Health Services experiencing some technical difficulties with the required data files.
