The data obtained in our study provided evidence of environmental contamination by SARS-CoV-2 and demonstrated the effectiveness of disinfection. Significant environmental contamination suggests that the environment is a potential medium of transmission.22 We proposed the following suggestions: (1) environmental surface disinfection should include wiping in an “S”-shaped motion and not repeating the area that has already been cleaned, according to regulations for hospital-associated infection control in the ward of healthcare facilities (WS/T510-2016); (2) the frequency of disinfection should be increased appropriately, at least 3 times per day: twice during the day and once at night (disinfection should be conducted at any time in case of obvious contamination); and (3) cleaners should be trained repeatedly to ensure that they are qualified for their job.
