Courier clothes that may also have the novel coronavirus on them need to be sterilized promptly to avoid infection. As the new coronavirus can survive for 2 to 3 days on the surface of various objects such as plastic, glass, paper shells and metal, the new coronavirus may be found on courier items. Rigorous disinfection can prevent infection by inactivating the new coronavirus on the items. The new coronavirus is sensitive to organic solutions and disinfectants, such as 75% alcohol, ether, chloroform and ultraviolet light can inactivate the virus. If it is a foreign object, it can be disinfected with ultraviolet light or 75% alcohol, which can inactivate the novel coronavirus to a certain extent.
