Discuss transmission modes of SARS-CoV-2 and its prevention and control countermeasures

Analyses the transmission mode of SARS-CoV-2 based on the typical confusing cases in the epidemic. Considers that there should be a mode of aerosol cloud transmission between droplet transmission and air transmission. If using the aerosol cloud transmission theory to analyse various cases in the epidemic, a reasonable explanation can be drawn. The new mode of transmission will put forward new requirements on intervention measures and personal protection. Therefore, puts forward the corresponding prevention and control countermeasures and focus points.
