Re-Entry Testing Curbs 150+ COVID Cases from UConn Campuses UConn’s re-entry testing strategies halted more than 150 positive cases – which often are asymptomatic in college-age students – from circulating and spreading on its campuses. (Sean Flynn/UConn Photo) Copy Link UConn’s comprehensive COVID testing for off-campus students with in-person classes or similar obligations helped identify, and avoid introducing, 75 positive cases into the student body, new re-entry test results show. Those positives are in addition to the 76 cases that UConn caught in re-entry testing of residential students, who had to quarantine and recover before they were authorized to move into their on-campus residence halls last month.
