As it has done frequently throughout the summer months, Iowa has updated the latest results of its COVID-19 testing.

On Monday, the school’s athletic department revealed that it has conducted an additional 335 tests, all of which were administered between Aug. 10 and Aug. 16. The results showed that there were four positive cases, and 331 tests returned negative results.

“Following the positive test result, protocol established by UI Athletics and medical staff, including contact tracing procedures, is being followed to ensure the safety of all UI Athletics student-athletes and staff,” Iowa said in a statement. “This mandatory protocol also includes isolation for the individuals who test positive, and quarantine for those individuals who might have been exposed to someone with the virus.”

Iowa has been like most schools in the B1G, providing updates as new testing information has become available. Testing in Iowa City began on May 29, when student-athletes, coaches and staff began returning to campus.

Since that May 29 date, Iowa has conducted 1,276. There have been 51 positive results with 1,225 negatives.
