Novel coronavirus pneumonia aerosol transmission, that is, aerosols may be the mode of transmission of novel coronavirus infection, which may lead to infection with novel coronavirus if exposed to higher concentrations of aerosols for a long time in a relatively closed environment. Aerosol is the nucleus of droplets formed by losing moisture in the air. Due to the loss of moisture, the quality decreases, so aerosol is suspended in the air, and if the virus exists for a longer time in poorly ventilated environments, it floats further than droplets. Aerosols are a possible route of transmission if in a confined environment so that the concentration of aerosols is increasing and can cause infection of others. The main way of transmission of New Coronavirus is still through air droplets, so prevention of New Coronavirus pay attention to the aerosol transmission that can be formed in a small space with poor ventilation such as elevators. So pay attention to avoid going to crowded places, to develop the habit of 1m line, hand washing and disinfection, especially in the elevator must wear a mask, do not mess with the items in the mold elevator.
