Data Notes for the Week of February 25

Read the 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 metrics page). We have a few notes for this week’s issue (data from February 8 through February 21):

There was no significant change in cases not associated with UW.

Dane County’s 14-day average number of cases is 88 per day, down from 95 last snapshot. In this period, there were 1,228 total cases. There was a significant increase in cases associated with UW-Madison (UW) during this 14-day period, and no significant change in non-UW cases. 50% of cases were UW students or staff, and 70% of tests were conducted by UW’s University Health Services (UHS). When excluding cases and tests from UHS, Dane County still has a low percent positivity of 2.0%.

UW continues to do the majority of testing happening in the county right now, which supports rapid identification of people with COVID-19 and helps to contain spread of the disease through contact tracing, isolation and quarantine support. We’re monitoring the situation closely for evidence of increasing case counts in other age groups. We are not currently seeing any such increase among other age groups.

16.7% of the Dane County population has received at least one dose of vaccine.

The number of people who have been fully vaccinated with two doses in the past ten weeks now exceeds the number of people who have gotten COVID-19 over the past year.

As of February 22, 143,435 doses have been administered to 91,435 people. For the latest vaccination numbers, see the Department of Health Services’ website. See our vaccination page for more information about currently eligible and soon to be eligible groups.

13 people (1.1% of all cases) were associated with assisted living or skilled nursing facilities.

There has been a large decrease in the number of cases linked to long-term care facilities over the past three months. Much of this is likely due to the overall decreasing trend of cases we’ve seen in Dane County, but it is also likely that vaccine administration over the past two months has helped to reduce the number of cases to an average of just one per day during this 14-day period. Nearly 3 out of every 5 Dane County residents age 65+ have received at least one dose of vaccine.

People in Dane County who have died from COVID-19 are still largely people associated with assisted living facilities. Of the 56 people who we have lost in January and February, two-thirds were residents of a long-term care facility.
