Aerosol transmission is the loss of moisture in droplets during air suspension and the remaining nuclei composed of proteins and pathogens, forming droplet nuclei that can float to distant locations in the form of aerosols, causing long-distance transmission. Aerosol transmission may generally occur in specific settings, such as in some clinical tracheal intubation operations, and there is no evidence of aerosol transmission of New Coronavirus. New coronavirus is still transmitted by proximal respiratory droplets, by coughing, sneezing, and speaking, over short distances, usually one to two meters, and does not float in the air for long periods of time.
