New coronaviruses leave the host and generally have a short survival time, which is just a few minutes before they may be completely inactivated. Because a virus is a pathogen that cannot survive on its own, it needs to attach to a living cell body to survive. But after the new coronavirus leaves the host, it tends to attach to the surface of some objects, such as door handles, elevator buttons. The specific survival time depends on the temperature and humidity on the surface of the object to which it is attached, and it can survive for 2-5 days if the temperature and humidity are appropriate. New coronavirus is sensitive to general disinfectants such as chlorine, alcohol, UV light, etc. Generally, the temperature is higher than 56°C and 30 minutes can inactivate the virus. However, the new coronavirus may be more resistant to low temperature and may survive longer in a low temperature environment.
