Study finds evidence of COVID-19 in air, on hospital surfaces
COVID-19 aerosol was found near air vents (5/14 [25.7%]), in patient rooms (8/18 [44.4%]), and in the doctor’s office area (1/8 [12.5%]), indicating that aerosolized virus was concentrated near and downstream of patients. However, the upstream area also posed a risk and that, based on the detection of virus in the doctor’s office, “the maximum transmission distance of SARS-CoV-2 aerosol might be 4 m,” they said.
“We’ve done some studies here in the United States and found that there is some aerosolized virus that is recoverable that can be isolated and is alive.
