Researchers suggest that improving the environmental sanitation quality can reduce the spread of pathogens in hospitals and even prevent hospital infection outbreak.8 However, the extent of environmental contamination by SARS-CoV-2 and the potential contribution of this contamination to SARS-CoV-2 transmission are poorly understood. The present study was performed in a designated hospital to evaluate environmental contamination in the air and surfaces by SARS-CoV-2 RNA qualitative detection and to investigate whether environmental contamination may play a role in SARS-CoV-2 transmission.
