LANSING — Michigan State University will ease some restrictions on campus because COVID-19 case numbers are declining after an initial spike when students returned last month. MSU officials announced an enhanced social distancing directive that began on Jan. 30, ordering on-campus students to remain in their dorms or apartments with few exceptions, like to go to in-person classes, to pick up meals, seek medical care or go to a job. The directive will be lifted Sunday, allowing more freedom for students on campus. The enhanced safety measures were enacted as positivity rates jumped to 1.78% among students participating in mandatory on-campus testing during the week of Jan. 25, according to MSU spokesperson Dan Olsen. It was just under 2%, the threshold at which it would become a concerning rate.
