Iowa has reported nine positive tests for COVID-19, according to a press release from the school’s athletic department. The school conducted 40 tests and 31 returned negative.

The results of the round of testing come between the dates of June 15 and June 21. So far, Iowa’s total of positive cases has reached 12 with 374 negative tests.

“While we have experienced an increase in positive tests, almost all are related to individuals who had been in quarantine due to our contact tracing and developed symptoms,” said Dr. Andrew Peterson, an associate professor and head team physician at Iowa. “Our overall process, including testing and daily health screening, is working as expected.”

Several B1G schools have allowed student-athletes to return to campus in a phased setting. Many have also reported positive COVID-19 tests, as well.

The NCAA lifted its moratorium on organized team activities on June 1.
