The SARS-CoV-2 virus, which causes COVID-19, is predominantly transmitted through the air, a new assessment by medical journal The Lancet states. The analysis done by six experts from the UK, the US and Canada has found “consistent, strong evidence” of the airborne transmission. It further says public health measures that fail to treat the virus as predominantly airborne leave people unprotected and allow the virus to spread. Moreover, transmission rates of SARS-CoV-2 are much higher indoors than outdoors, and transmission is greatly reduced by indoor ventilation.
“The evidence supporting airborne transmission is overwhelming, and evidence supporting large droplet transmission is almost non-existent,” said Jose-Luis Jimenez, a chemist at the Cooperative Institute for Research in Environmental Sciences (CIRES) and the University of Colorado Bould. “It is urgent that the World Health Organization and other public health agencies adapt their description of transmission to the…
