(Sean Flynn/UConn Photo) UConn’s multi-step COVID-19 testing process prevented the introduction of 76 positive cases into the student body as undergrads returned to residence halls last weekend for the spring semester. Residential students were required to test negative at home recently and again in person on campus last weekend before they could receive their keys and move in. Their return kicked off a two-week campus-wide quarantine that is currently in place, a precautionary period during which time all classes are online.
