Aerosol transmission is the formation of droplets in the air that are absorbed by the body and can lead to infection. Many respiratory illnesses can be spread by aerosols, and this is not a new route of transmission. Elevators are considered a high-risk area for aerosol transmission and theoretically have the potential to be infectious. A certain amount of virus is required to cause disease. In open and less crowded environments, aerosols may be diluted or blown away, and if the amount of virus is small, the chance of infection is reduced. However, the risk of aerosol infection increases in enclosed spaces such as elevators and offices. Therefore, you should minimize going out, not partying, wearing a mask when going out, it is recommended that the body should not touch the elevator equipment, when pressing the elevator, you can use paper towels to isolate and then press the elevator buttons, and wash your hands immediately after you get home; masks can play a protective role, reminding people to wear masks correctly. Wearing masks should strictly cover the mouth and nose, minimize the gap between the face and the edge of the mask; to reduce the gathering, queuing should be spaced about 1.5-2m apart to form a safe isolation distance to reduce aerosol infection.
