Madison365 is providing data for growth by race and ethnicity and by age for the past two weeks with the following interactive charts below:

According to the University of Wisconsin-Madison’s data dashboard, as of 2 pm yesterday, UW testing has confirmed a total of 386 total cases, which now includes cases from both on campus and off campus testing. In total, there are 365 students and 21 employees who have tested positive for COVID-19 since July 28th. For what UW received on September 2nd, there was  total of 59 (34 on campus and 25 off campus) while September 1st was updated to 57 total positives (49 on campus and 8 off campus).  For September 2nd, the 7 day combined average is 32.6 while on September 1st it was 28.1. For on campus testing, the 7 day average of 2.0 percent for students while employee testing 7 day average of .3 percent. All positive cases from UW are reported in Dane County numbers. As of this morning, UW has run 12,367 tests since on campus testing began on August 6. UW has completed their move-in testing and have transitioned to biweekly surveillance testing of those in residence halls. According to yesterday’s update, there are currently 20 students in on-campus quarantine as well as 25 students in on-campus isolation with most resident hall students choosing to return home to quarantine or isolate for the appropriate period.

For all of Dane County, the most updated data on positive test percentage for a single day is for September 3, with the positive test percentage reported at 2.3 percent while September 2 is at 1.9 percent. The positive percentage for September 1 has been updated to 5.4 percent and August 31 is now at 2.5. Madison365 expects that these numbers will be adjusted as more negative and positive tests are fully processed and attributed to the appropriate dates in the coming days. The break down for each day can be found on Public Health of Madison and Dane County’s Dashboard.

Yesterday, Public Health of Madison and Dane County updated their Data Snapshot for the week of August 18 – 31 with a look at those past two week’s data including Department of Health Services’ activity level metric. The activity level metrics measures the burden of cases within the last two week period (number of cases per 100,000) and the trajectory – or the percent change in cases from previous to the current week and if that trajectory is statistically significant.

According to the update, the current activity level for the county remains high as the trajectory has begun to growth is now statistically significant. Dane County reportedly still has high burden of cases as reported last week, however – we have grown from 110 cases per 100,000 according to last week’s snapshot to 120 cases per 100,00.

Currently, for August 18 – 31, Dane County has also grown in average cases per day from 41 cases per day to averaging 45 cases per day. This metric remains red according to the update and will continue to be red until we average fewer than 20 new cases per day for it to move to yellow and below four cases per day to move to green. For those dates, the percentage of those who test positive that have been contacted within 48 hours of their reported results decreased from last week’s 79 percent to 73 percent. This does keep the metric in the yellow. We need to be at 85 percent for it to turn green. Though last week’s snapshot reported that the percentage of those who tested positive who did not know where they would have gotten COVID from was at 41 percent, this week it increased to 40 percent keeping this metric red as well.

Communities of color are overrepresented in hospitalizations and in cases. According to the snapshot, those who identify as Hispanic/Latinx are underrepresented in all tests – being only five percent of all people tested for the weeks of August 18 – August 31 while making up six percent of the Dane County population. They are also 13 percent of all new cases for those dates, an increase from 10 percent last week, and 56 percent of hospitalizations – more than double of where they were last week for hospitalizations at 25 percent. Black people though six percent of the population in the County continue to be underrepresented in testing with only five percent of all tests for August 17 – August 31, were also overrepresented in hospitalizations at 11 percent, though a decrease from last week’s 17 percent. Black people for this time period make up 5 percent of all tests. Those who are Asian were only four percent of all tests during the last two weeks while seven percent of the total population for the county and make up five percent of all positive tests and eight percent of all hospitalizations for August 11 – 25.

For context, Public Health of Madison and Dane County reported specifically on UW cases again this week. As students, staff and faculty return to campus with students moving back in as early as August 15, Public Health began to track COVID positives for students, faculty and staff as early as July 28. UW students and staff make up 27 percent of Dane County’s new cases confirmed August 18-31 – 163 students and eight staff. This includes any student or staff person tested on campus and off campus. Ninety-three percent of those cases were between 18-22 while 28 percent of that 171 were associated with a cluster (47 from college-aged housing including sororities, fraternities, near campus apartments and one from a workplace).

Dane County and Public Health also reported a break down of ages for those between 0-25 as those ages have been steadily climbing during August 18-31. For those 14 days, 47 percent, or 299, cases were under the age of 24. Of those, 83.6 percent or 250 cases were between 18-24 while those aged 11-17 made up 9.3 percent or 28 cases. Children aged 5-10 made up 5.7 percent or 17 cases and children aged 0-4 made up 1.33 percent or four cases.

Yesterday morning, Madison365 updated our interactive Dane County Coronavirus Map. The map will be updated weekly.

We will have an update of today’s statewide numbers later this afternoon.
