Data Notes for the Week of May 6

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 19 to May 2.

Cases decreased during this 14-day period.

13% of cases were UW students or staff and 61% of tests were conducted by UW’s University Health Services (UHS). Our percent positivity is 1.1%. When excluding cases and tests from UHS, Dane County still has a low percent positivity of 2.4%.

Over the past four weeks, cases have decreased among ages 12-29 and 40-59 and remained stable among all other age groups.

There 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.

Over 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, 60.7% have received at least one dose of vaccine and 47.2% have completed the vaccine series. Among the eligible (16+) population in Dane County, 74% have received at least one dose.

As of May 5, 21,825 UW students (48%) have received at least one dose of vaccine. UW students are counted as part of our Dane County population and are reflected in our county-wide vaccination numbers. Data quality related to addresses is a challenge, particularly for college students who may still have their parents’ address in the immunization registry. This is why we present the number of UW students vaccinated on page 5 of the snapshot, as this provides a more reliable look at vaccination within our UW-Madison community.

An average of 5,353 doses of vaccine were administered to Dane County residents each day during this 14-day period, which is 19% lower than last week.

Based on our current 7-day average of 1,381 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 26. Keep in mind this data point is different from the average of 5,353 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. Both have slowed over the past couple of weeks as demand for vaccine no longer exceeds supply, but may increase again once more ages become eligible.

News sources across the country are reporting that the Pfizer vaccine could be authorized for children 12 to 15 years old very soon. This is exciting news, as it would mean an additional 25,000 to 30,000 people in our county will be eligible for vaccination—and will help us get closer to herd immunity!

While this authorization for 12-15 year olds hasn’t happened yet, we published a blog this morning that outlines what parents and guardians need to know about getting their 12-15 year olds vaccinated when the time comes.
