OMAHA, Neb. (AP) — Two sororities at the University of Nebraska-Lincoln are under quarantine after several coronavirus cases were reported at each house during the first week of classes.

University officials said Wednesday that everyone living at the Delta Delta Delta sorority house has been placed under quarantine after five cases of the virus were reported there.

Earlier in the week, the Kappa Alpha Theta sorority house on campus was also placed under quarantine after a separate cluster of five cases was reported there.

Classes began in person Monday at the university in Lincoln.

Elsewhere, Omaha school board President Marque Snow said Tuesday that he would suspend all his campaign events and isolate himself after testing positive for the virus. Snow is running for the state Legislature.

The Omaha school district is relying only on online instruction this fall because of concerns about the spread of the coronavirus. The school board last met in person on Aug. 17.

Nebraska reported 379 new cases of the virus Wednesday to give the state 32,727 cases of coronavirus. There have also been 386 virus deaths.

The seven-day rolling average of daily new cases in Nebraska has decreased from 264.57 new cases per day on Aug. 12 to 217.57 new cases per day on Wednesday.
