The transmission routes of novel coronavirus pneumonia are becoming clearer and better understood. Basically, the clearer routes of transmission of novel coronavirus pneumonia are respiratory droplet transmission and contact transmission. In addition, people may be at risk of infection if they are exposed to high concentrations of virus-containing aerosols for long periods of time. To avoid respiratory droplet transmission, it is important to wear a mask when coming into contact with people, keep a distance of more than 1 meter as far as possible, and always cover the mouth and nose when coughing. To avoid contact transmission, it is important to minimize touching surfaces when you are outside and to wash your hands frequently when you return home. The risk of infection can be greatly reduced.
