The week of March 9 was unlike any other at Princeton. In response to concerns about the spread of the 2019 novel coronavirus (COVID-19), the University undertook a rapidly evolving series of measures that included the temporary move of all classes to online instruction, the cancellation of all athletic contests for the spring season, and ultimately a decision for all undergraduate students to return home, except for those whose academic, financial, travel, housing, or immigration and visa situations made it necessary to stay. The global coronavirus outbreak had already disrupted the studies of undergraduates in study-abroad programs, but the new measures touched every aspect of student life. PAW lays out a timeline that highlights some of the developments of an eventful week.
