Calum Best, a senior from Alexandria, Virginia, returned to his dorm despite concerns about the virus. He has a job on campus, he said in an interview, and there are opportunities to help people in need. He also was concerned he might put his parents at greater risk if he were living at home. He said he was being careful about social distancing and would stay as long as he feels he can do so safely. His two roommates have not returned, he said.
