Data Notes for the Week of April 29

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 metrics page). The data below are from April 12 to April 25.

Cases were stable during this 14-day period.

13% of cases were UW students or staff and 64% 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 2.7%.

Over the past four weeks, cases have decreased among ages 30-39 and 50-59 and remained stable among all other age groups, including children.

After weeks of increases in cases among many age groups, there now are no age groups that are increasing. Our chart on page five of the Snapshot outlines cases among each group compared to the prior two weeks.

Anyone 16 years old and older is able to get vaccinated. We’re seeing the biggest jump in COVID-19 vaccination right now among 16-17 year olds. 51.5% of Dane County residents in this age group now have at least one dose of protection, up from 44% just last week. That’s amazing progress when this group has only been widely eligible for vaccine for four weeks.

That being said, we are still seeing multiple clusters among high school students. Some transmission is suspected to have occurred when students left school during lunch and ate together in the car with no masks. We encourage students who are 16 or older to get vaccinated as soon as possible to protect themselves and their classmates who aren’t yet old enough to get vaccinated.

Nearly 60% of Dane County residents have at least one dose of vaccine, which is the highest in the state.

Among all people in Dane County, 59% have received at least one dose of vaccine. Among the eligible (16+) population in Dane County, 72% have received at least one dose. 43.5% of Dane County residents have completed the vaccine series.

An average of 6,641 doses of vaccine were administered to Dane County residents each day during this 14-day period, which is 9% lower than last week.

Based on our current 7-day average of 2,304 newly vaccinated people per day, we could expect 80% of the eligible Dane County population to have at least one dose of vaccine by May 15. Keep in mind this data point is different from the average of 6,641 doses of vaccine administered each day during this 14-day period that is listed on page one of the Snapshot. Looking at both people vaccinated and doses administered is important.

Our vaccination clinic at Alliant Energy Center can now accommodate drop-ins. Make an appointment or just stop by during clinic hours to get vaccinated! Visit our website for more details.

In case you missed it last week, we recently published a blog that explains why we look at both the total population and the eligible population when assessing vaccination rates. It's important to look at both these measures to get a more complete picture of herd immunity and vaccine equity, access, and uptake.
