GREENVILLE, S.C. (AP) — Officials at a private Christian college in South Carolina said Monday that the school is stepping down its coronavirus-related mask requirements as it experiences fewer COVID-19 cases on campus.

Beginning Tuesday, masks will no longer be required in classrooms at Bob Jones University in Greenville, once students are seated, and instruction has begun, university President Steve Pettit announced Monday in a news release. Masks are still required to enter all public buildings at the school, as well as in other places around campus, officials said.

Bob Jones officials said that the campus has seen a 90% drop in its COVID-19 positivity rate since the beginning of February. As of Monday, officials said there were only three positive cases among the student body of around 3,000, as well as one case among faculty and staff.

Masks are still largely required across South Carolina's institutions of higher learning, even during in-person classroom instruction time.
