To limit exposure on our campus, Mason is extending spring break by an additional week through March 20. This will allow students and faculty to prepare for virtual alternative instruction and reduce close contact on campus. When spring break ends, most classes will be conducted through virtual alternative instruction, from Monday, March 23 through Friday, April 3.  Students will be contacted by their faculty with additional details about virtual learning. The university will continue to monitor and reevaluate the situation prior to April 3.
