Data Notes for the Week of January 13

Read Data Snapshot

You can find past issues on our data and dashboard page. The data below are from December 27-January 9.

Due to record-breaking numbers of cases over the past three weeks, not all recent cases have been fully processed into our data system, and therefore certain data points such as vaccination status are not yet available for those cases. Case data by vaccination status is not reported this week, and the Public Health measures on p.2 are restricted only to cases that have been fully processed. Next week we will provide an update on case, hospitalization, and death rates by vaccination status for the months of November and December.

2.9% of the entire Dane County population tested positive with a PCR test during this 14-day period.

Cases increased during this 14-day period with an average of 1,159 cases per day. Nearly 1 out of every 33 residents of the entire Dane County population tested positive with a PCR test during this 14-day period—and there are even more people who tested positive only with a home COVID test or another antigen test. If you’ve taken a home test, please report it so that we can better understand the level of virus spreading in our community.

The number of people hospitalized with COVID in Dane County hospitals also increased with an average of 172 people hospitalized each day. Percent positivity is at its highest-ever level of 20.1% and an average of 5,774 tests were conducted per day. A high percent positivity means we are likely missing cases in our case counts. If you have symptoms or were exposed and need a test, we opened a walk up testing site at the Alliant Energy Center this week to increase access to testing.

The age-adjusted COVID death rate decreased by 49% after vaccines became available, showing how important it is to get vaccinated and boosted.

The age-adjusted average monthly COVID death rate per 100,000 population decreased by 49% in Dane County after vaccines became widely available (June 2021-December 2021 compared to March 2020-May 2021). The death rate decreased by 39% in the five most vaccinated counties in Wisconsin, decreased by 17% in Wisconsin overall, and increased by 32% in the five least vaccinated counties in Wisconsin. This shows the effect vaccination has had in protecting Dane County residents from the most severe outcome of COVID.

 

58.9% of fully vaccinated people in Dane County have gotten a booster or additional dose.

61.6% of fully vaccinated people ages 12+ and 83.9% of fully vaccinated people ages 65+ have received a booster/additional dose. It is vital to be up-to-date on your COVID-19 vaccinations for the best protection from severe outcomes. If you still need your booster, visit our website to get an appointment at a clinic or find a mobile vaccine clinic near you.
