The outbreak, at an off-campus sorority house near the university's Stillwater location, was detected by rapid-antigen testing done at an off-campus clinic, the university said in a statement Saturday. The university and the Payne County Health Department are monitoring the chapter and performing contact tracing.
"Due to the nature of this situation, the entire chapter house is in isolation or quarantine and will be prohibited from leaving the facility," the school said. "One member of the sorority who lives elsewhere is among those who tested positive and will also remain in isolation."
