Dane County confirms 179 new coronavirus cases; UW case count passes 2,500


Dane County confirmed 179 new coronavirus cases this morning, as new cases spread slowly begins to spread among age groups other than the 10-29 age range that has led to much of the growth in new cases in recent weeks.

Today’s new cases bring the total for the county to 8,640 as of this morning. There are 6,714 recovered cases while 1,885 are currently active. This drops the percentage of active cases slightly to 21.8 percent.

Most of the 179 new cases were attributed to tests processed September 18, with 162 positive cases reported for that date while 14 were attributed to September 17. The rest of the positive cases were attributed to other dates this past week. September 9 continues to hold the record for a single day increase with 487 positive cases attributed to that day.

The percentage of cases in age groups in 10-19 and in their 20s continue to drop as cases have continued to spread to other ages. Almost 35 percent of cases were in those aged 10-19 with 62 new cases and almost 32 percent were in those in their 20s with 57 new cases. No further breakdown in the age group between 10-19 was provided for today’s numbers.

Since September 5, cases in ages 10-19 have grown by 159 percent, while cases in those in their 20s have grown by 37 percent in the last two weeks. Cases in children aged 0-9 have grown by 19.47 percent for the same time period.

Dane County’s seven-day average for cases is now at 167.2 while the 14-day average is now 189.1 cases per day. The Forward Dane reopening plan required that the daily new case average fall below 20 before moving to the next phase. On Wednesday, PHMDC announced that they would be stepping up enforcement on bars and restaurants with the assistance with Madison Police.

The most updated data on positive test percentage for a single day is for September 18, which is at 3.8 percent while the positive test percentage for September 17 is at 3.8. The positive percentage for September 16 has been updated to 5.4 percent and September 15 is at 4.1 percent. 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.

On Thursday, a new Data Snapshot from Public Health Madison Dane County (PHMDC) reported 72 percent of all new cases the September 1-14 were from UW students and staff. It also noted that for those dates, only 3 percent of cases for those two weeks were aged 0-17 while 80 percent of all new cases were between the ages of 18-22.

According to the University of Wisconsin-Madison’s data dashboard, as of 2 pm yesterday, Public Health of Madison and Dane County and UW testing had confirmed 112 new positive cases from UW. Of that 112, 87 came from on campus testing and 25 from off campus. In total, there were 108 additional new positive tests for students and four for employees, and one student hospitalized with complications of COVID-19.

According to UW’s data dashboard, they have attributed all of the 112 positive tests to September 17 . UW attributes positive tests to the date results are received and not on the date a test was taken. PHMDC attributes results to the day a test was taken.

The seven day average of UW-related cases per day has decreased to 111.7. The seven-day percentage of positives for students on campus is at 7.5 percent. In total, there are now 2,511 positive cases from UW: 2,466 from students and 45 from employees. UW students continue to make up 98.2 percent of all UW cases. Of those 2,511 cases, 1,712 were identified in on-campus testing. As of this morning, UW has run 32,072 tests since on campus testing began on August 6 with 5.3 percent of those tests coming back positive.
