To prevent aerosol transmission, you should avoid closed environments and keep the environment ventilated; wear a mask and keep a distance of more than one meter from others; avoid public places where people gather; and wash and disinfect your hands regularly. Aerosol transmission is when droplets mix in the air to form an aerosol that can be inhaled and lead to infection. To prevent potential aerosol transmission, disinfection and ventilation can be used. 1. The environment needs to be kept ventilated and airy, especially in crowded places or places where there have been carriers of the virus. Avoid enclosed spaces and relief. 2. For those in hospitals or crowded places, aerosol transmission can be prevented by disinfecting the environment. 3. Avoid crowded places as much as possible, wear a mask when going out, and disinfect your hands frequently. 4. No matter what kind of environment you are in, try to keep a distance of more than one meter from others. For non-hospital environments, places with low crowd density and good ventilation usually have a lower chance of aerosol transmission.
