The residence time of novel coronaviruses on articles varies depending on the surface conditions of the articles. The residence time of novel coronaviruses on articles is affected by a number of factors, such as the degree of wetness or dryness of the article, temperature, etc., which will affect the residence time of the virus. Novel coronaviruses survive for about 2 hours in air, and can generally survive for 48 hours in dry environments. And with the extension of time, the activity of novel coronaviruses decreases significantly after 2 hours in air, so their infectiousness will be weakened as well. If the temperature and humidity in the environment are not suitable, then the virus does not survive for a long time. In other cases, however, the novel coronavirus can survive for up to 24 hours on cardboard surfaces, up to 4 hours on metal surfaces such as copper, and up to 72 hours on plastic surfaces. It may stay longer on stainless steel surfaces. The new coronavirus can be infected through the indirect contact of articles, for the characteristics of the new coronavirus in the residence time of articles, this time should strengthen the corresponding disinfection, according to the characteristics of its biology, choose different disinfectant to be the local disinfection of articles, so as to reduce the infectiousness of the new coronavirus.
