There are at least 342 individuals affiliated with the university who have tested positive for the virus since August 24.
At least a third of new cases are individuals who recently attended parties or social gatherings, and at least a third of those gatherings are associated with a fraternity or sorority, the health department said Saturday in a statement.
Only 23 university-affiliated people tested positive for the virus in the three weeks before the case surge. The increase in cases began as students returned to East Lansing for their fall semester.
“Although MSU classes are predominately online, many students had binding off-campus leases or simply desired to physically return to the university community,” the statement said. “Self-quarantine should last for 14 days, continuing until 11:59 p.m. on Saturday, September 26. This recommendation is not an emergency order; however, more stringent and mandatory restrictions will be imposed if students do not comply and break the transmission cycle.”
