The number of University of Wisconsin athletes who have tested positive for COVID-19 has climbed to 83, the athletic department reported Thursday.

Among 734 athletes who have returned to campus since June, 58 have tested positive through samples taken by the athletic department. Another 25 athletes tested positive for the coronavirus at other testing sites since they first returned to UW.

With those figures combined, the 83 athletes who have tested positive represent more than 11% of Badgers athletes on campus. In the last figures reported in early August, 8% of athletes had tested positive.

From Aug. 6 to Wednesday, 62 Badgers athletes tested positive for the first time.

The UW-Madison campus has experienced an outbreak since students returned to start the fall semester. Through Wednesday, UW reported 1,433 positive tests from students and 27 from employees, with more than a third of the positive tests coming in the last three days.
