Rumor Analysis: Aerosol transmission refers to the loss of moisture in the air suspension process of droplets, while the remaining proteins and pathogens composed of nuclei, can float to a distance through the form of aerosols, resulting in long-distance transmission. At present, the new coronavirus transmission route has been confirmed, or respiratory droplet transmission and contact transmission, while the aerosol transmission mode has yet to be verified. 1, respiratory droplet transmission, the patient coughing, sneezing, loud talking when the droplets and exhaled gas is directly inhaled by susceptible persons in close proximity, can lead to infection. 2, contact transmission, droplets deposited on the surface of objects, contact and contaminated fingers, and then contact with the susceptible person’s oral cavity, nasal cavity, eyes and other mucous membranes, can also lead to the occurrence of infection.
