Based on aerosol mechanics, the transmission mode of SARS-CoV-2 was analyzed. It is considered that there should be a transmission mode of aerosol cloud between droplet and airborne. If we use the theory of aerosol cloud transmission to analyze all kinds of suspected airborne cases in the epidemic situation, we can get a very reasonable explanation, and put forward the corresponding concerns and prevention and mitigation measure for this mode of transmission.
