The John Harvard statue at Harvard University, a popular tourist attraction at the campus in Cambridge, Mass, sits adorned with a medical mask as students prepared to leave campus, Saturday, March 14, 2020. The university has asked students to leave by Sunday afternoon and stay home after spring break to prevent the spread of the new coronavirus. For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The vast majority of people recover from the new virus.
