O’FALLON, Mo. (AP) — The University of Missouri in Columbia says two students have been expelled and three others suspended for violating rules meant to slow the spread of the coronavirus. The disciplinary actions were announced Tuesday. A news release says the sanctions were necessary because of flagrant violations of rules and regulations that require students who test positive for the coronavirus to isolate themselves and comply with social distancing requirements. More than 1,300 of the university’s students have been infected. All told, 470 students have been called to the university’s Office of Student Conduct and Accountability for possible violations of coronavirus policies. Eleven student organizations are under investigation.
