Novel coronavirus-positive articles may infect people. Infection of humans with novel coronavirus-positive articles is subject to several conditions, including the presence of live viruses on the articles, the presence of a chain of transmission, and susceptible populations. The live virus on the object replicates in the body after human infection, forming an object-to-human transmission; the live virus attaches to the surface of the object and spreads to people through the air or by direct contact, and the virus can survive in the body when the person who touches the object does not have immunity or antibody protection. In general, the risk of transmission of positive items is low when judged by a combination of factors such as the transmission route and the survival time of the virus on the surface. Patients are advised to avoid purchasing items from medium to high-risk areas when purchasing items online, and to choose contactless receiving methods. Avoid touching the mouth, eyes and nose with hands when going out, and disinfect the internal and external surfaces of received items to avoid infection. Patients are advised to go to the hospital and ask for precautions against novel coronavirus to prevent infection with novel coronavirus.
