Dane County confirms 137 new cases as infection spreads across age groups


Dane County confirmed 137 new coronavirus cases this morning bringing the total to 9,326 for the county. A significant portion of  age groups saw double-digit increases as numbers spread beyond those aged 10-29, which have made up the bulk of new cases for much of the month.

There are now 7,688 recovered cases while 1,597 are currently active. This brings the percentage of actives cases 17.12 percent – a slight increase from yesterday’s 17 percent.

Of the 137 new cases, 90 were attributed to tests processed September 24, while 39 were attributed to September 23 for an increase in cases for that date to 156. September 9 continues to hold the record for a single day increase with 487 positive cases attributed to that day.

Though most cases were in age groups that were 10-19 and 20-29 with 30 new cases for each, other age groups are starting to see significant increases in their totals as well. Those aged 10-19 and 20-29 both made up 21.9 percent of today’s case. However, adults in their 30s grew by 22 additional cases as adults in their 40s grew by 18 and adults in their 50s by 16. Those aged 60 also saw double digits today as they grew by 12 more cases while children aged 0-9 grew by 6. Adults aged in their 70s, 80s and 90s all grew by one additional case.

As reported by PHMDC’s updated Data Snapshot, cases among these other age groups have been steadily rising over the past two weeks. As shown in the graph below, those aged 10-19 grew by 47.3 percent from two weeks ago while those in their 20s grew by 24.8 percent. However, cases in children aged 0-9, have grown by 26.1 percent from September 11 while adults in their 40s have grown by 23.7 percent.

Dane County’s death toll from COVID-19 remained at 41 today. As of this morning, there are currently 23 county residents hospitalized for COVID-19, with six of those are in the ICU. The total number of Dane County residents ever to be hospitalized for COVID-19 rose to 363.

Dane County’s seven-day average for cases is now at 129.8 while the 14-day average is now 152.7 cases per day. The Forward Dane reopening plan required that the daily new case average fall below 20 before moving to the next phase.

The most updated data on positive test percentage for a single day is for September 24, which is 2.7 percent, while the positive test percentage for September 23 is 3.4 percent. The positive percentage for September 22 has been updated to 5 percent and September 21 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.

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 58 new positive cases from UW, all from UW students. Of that 58, 32 came from on-campus testing and 10 from off-campus testing.

According to UW’s data dashboard, they have attributed all of the 58 positive tests to September 23. 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 80.9. The seven-day percentage of positives for students on campus is at 4.6 percent and as reported, decreased from a week ago when it was at 8.3 percent. In total, there are now 2,833 positive cases from UW: 2,784 from students and 49 from employees. UW students continue to make up 98.2 percent of all UW cases. Of those 2,784 cases, 1,945 were identified in on-campus testing. UW now has a percentage of positive of 5.1 percent for all positive tests since testing began on August 6th.

This 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.
