STILLWATER, Okla. — An entire sorority house is under quarantine at Oklahoma State University after 23 members tested positive for coronavirus, university officials confirmed.

Oklahoma State University officials confirmed Saturday that 23 members of Pi Beta Phi sorority tested positive for COVID-19.

University officials were alerted Friday night and put the entire off-campus sorority house in isolation, according to multiple reports.

Only one of the cases is symptomatic, according to the university. 

A third-party company disinfected the sorority house, and will do so again after the two-week quarantine period.

The people infected will be monitored by both the university and the Payne County Health Department, who will also be conducting contact tracing.

Pi Beta Phi's positive cases were announced the same day Oklahoma State University's sororities celebrated the end of recruitment week, according to The Oklahoman. All participating sororities hosted virtual recruitment events this year, including speaking with prospective new members over video calls.
