Shedding of Viable SARS-CoV-2 after Immunosuppressive Therapy for Cancer

Abstract
Detection of replication-competent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the most reliable indicator of contagiousness.1 Although the duration of live-virus shedding is well-characterized in immunocompetent patients with coronavirus disease 19 (Covid-19), little is known about how long immunocompromised patients are contagious. Consequently, the Centers for Disease Control and Prevention (CDC) guidelines on transmission-based precautions for immunocompromised patients are based on limited data.2
