Dane County hits new record with 166 cases reported today; PHMDC urge residents to avoid gatherings


Public Health of Madison and Dane County are urging residents of the county to avoid gatherings outside their household as they confirm 166 new coronavirus cases today, hitting a new high for the county for a single day. Though 19 of those 166 cases were attributed to other days this week, 147 cases attributed to Saturday is still the highest number of positive tests reported in one single day since the beginning of the pandemic. This brings the county’s total coronavirus cases to 6,129. As of this morning, the total number of recovered cases was listed at 5,039.

PHMDC said at least half of the new cases are University of Wisconsin students and staff. This includes only those tested on campus, and the proportion may rise as contact tracing confirms additional students and staff who were tested at off-campus facilities.

Dane County’s seven-day average for cases is now 97.5 cases per day while the 14-day average is at 74.14 cases per day. The Forward Dane reopening plan requires that the daily new case average fall below 20 before moving to the next phase. Further, PHMDC requires a daily new case count below 39 for four consecutive weeks to open schools for grades three through five, and below 19 for four consecutive weeks to open grades six through twelve, for in-person instruction. PHMDC has also said that if the daily case count exceeds 54, it may require all schools to close, even for kindergarten through second grade, which currently may remain open.

Dane County’s death toll from COVID-19 remained at 40 today. As of this morning, 22 people are hospitalized with COVID-19 in Dane County, with 11 of those in the ICU. The total number of Dane County residents ever to be hospitalized for COVID-19 is now at 335.

Young people aged 10-19 grew significantly today with triple digits – hitting 100 new cases. They were 60.24 percent of all new cases. Adults in their 20s grew by double digits with 45 new cases, making up about 27 percent of all new cases today.  As the graphs by age below show, infection in those aged 10-19 has grown about 81.8 percent over the last two weeks while adults in their 20s have grown to almost 16.4 percent in cases over the same time frame.

Adults in their 30s grew by seven cases while adults in their 60s grew by six. Those in theirs 50s grew by five additional cases today while children aged 0-9 grew by two cases and those in their 40s grew by one additional case each.

Yesterday, Public Health of Madison and Dane County tweeted this that current contact tracing shows that almost four out of 10 people who tested positive had attended a party or gathering of some sort.

UW-Madison and Public Health of Madison and Dane County also directed nine UW-Madison fraternities and sororities in off-campus chapter houses to quarantine for at least 14 days as a number of members in those houses have tested positive.
