|In order to find out the SARS-CoV-2 contamination in the air and the surface of ventilation system in a geneal COVID-19 ward of an infectious disease hospital, four air aerosol samplers were used in the COVID-19 ward of the hospital. 46 air aerosol samples were collected from both inside and outside of the ward, and 1 sample was weakly positive. Sterile swabs was used to collect 12 samples of dust on the surface of the air conditioning and ventilation system in the ward, and one sample was weakly positive. The results show that SARS-CoV-2 exists in the air of general wards and surface of some ventilation system objects. The virus has the risk of short distance transmission through aerosols. Medical staff should strengthen personal protection, strictly implement infection prevention and control measures, and reduce the internal risk of environmental cross infection.
