We used a strand-specific RT-qPCR to evaluate viral replication as a surrogate for
infectiousness among 242 asymptomatic inpatients with a positive severe acute respiratory
coronavirus virus 2 (SARS-CoV-2) admission test. Only 21 patients (9%) had detectable
SARS-CoV-2 minus-strand RNA. Because most patients were found to be noninfectious, our
findings support the suspension of asymptomatic admission testing.
