SARS-CoV-2 surveillance and outbreak response on an urban American college campus

Objective The George Washington University (GW) in Washington, D.C., USA established the Public Health Laboratory and Campus COVID-19 Support Team (CCST) to develop and implement its SARS-CoV-2 surveillance testing and outbreak response for the 2020-2021 academic year. Participants and Methods Approximately 4,000 GW members had access to campus for living accommodations, limited in-person instruction, athletics, research, and university operations. The outbreak response included daily risk assessment surveys, weekly surveillance testing, symptomatic and voluntary testing, case investigation, and contact tracing. Results Between August 17 - November 24, 2020, 42,350 SARS-CoV-2 PCR tests were performed, and 194 (0.46%) of tests were positive. Surveillance testing identified 59 (30.4%); voluntary testing 97 (50%); and symptomatic testing 30 (15.5%) of the cases, respectively. Conclusions Robust testing of asymptomatic people and rapid isolation and quarantine of members who are exposed or infected effectively limited the spread of SARS-CoV-2 during the Fall 2020 semester.
