Jiang Rongmeng, Chief Physician of the Second Department of Infection, Beijing Ditan Hospital: The virus is spread through droplets and contact. In the air, the spread of droplets is very limited, about a distance of one to two meters, and soon after coming out of the human body It settles, so it won't float in the air. In this sense, there will be no virus in the air.

Droplets can settle on surfaces, or contaminated surfaces touched by virus-bearing hands, such as doorknobs, elevator buttons, and now studies have found that viruses can survive for hours on these smooth surfaces. If the temperature and humidity are suitable, it is possible to survive for several days. For example, the temperature of 20 degrees Celsius is particularly suitable in an air-conditioned environment with a humidity of 40% to 50%. Some studies have found that the past coronavirus may survive for up to 5 days. Based on this, the virus spreads through contact, that is to say, if a person sneezes and does not pay attention to cover, there will be a virus, and the virus contaminates doorknobs and elevator buttons. If the next person does not wash their hands, rub their eyes after contact. , Picking the nose, it is possible to spread the virus through contact. Respiratory infectious diseases are spread by droplets, more often by hands, so be sure to wash your hands well, which is a particularly important point.
