SARS-CoV-2 Surface Contamination and Viable Virus in High-Ventilation Single Rooms: Implications for Fomite Transmission

Objectives To evaluate Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) contamination in the rooms of Coronavirus disease 2019 (COVID-19) patients by integrating RNA quantification, viral culture, and post-culture cycle threshold (Ct)-based estimation of infectious titer, and to reassess fomite transmission risk relative to the human infectious dose.
