Neocoronavirus is transmitted by several main routes, including respiratory droplet transmission, contact transmission, and fecal-oral route. The main source of infection of the new coronavirus is the new coronavirus infected people, including asymptomatic infected people and new coronavirus pneumonia patients. When an infected person sneezes or coughs, droplets containing the virus are produced, which can be inhaled and infected by others in close contact. Infection can also be caused by direct hand-to-hand contact with contaminated surfaces or the environment. New coronavirus can be excreted with the excreta of the infected person, and there are scientific research reports that other people can be infected through the fecal-oral route; therefore, it is important to wear a mask correctly when going out, pay attention to hand hygiene, and try to maintain a safe distance of more than 2 meters.
