Novel coronavirus pneumonia is airborne. Although novel coronavirus pneumonia can be spread through the air, certain conditions must be met. Mucus from the patient’s respiratory tract turns into tiny droplets when the patient sneezes or coughs, and the virus-carrying droplets are suspended in the air and can infect healthy people when they come into contact with the droplets. In addition, some patients’ secretions or mucus with virus in the airway can become aerosols. The so-called aerosols are smaller particles than droplets, which can float in the air for a long time, and their transmission distance is greater than the distance or range spread by sneezing or coughing. If you are not well protected and come into contact with the patient’s aerosol, you may be infected by the coronavirus. Therefore, if you want to prevent the new coronavirus, you should first pay attention to air disinfection, you can use ultraviolet light, etc. to disinfect the air, in order to prevent the patient aerosol or droplets from spreading to the healthy people through the air.
