Neocoronaviruses do not survive in a vacuum. Neocoronaviruses need a host to survive and reproduce, and once removed from the host environment, they have difficulty surviving. In a vacuum, without a host and oxygen, the virus cannot survive. Even in the air, without a host, the new coronavirus cannot survive for very long. The ability of neocoronaviruses to survive on the surface of an object ranges from a few hours to a few days, depending on the temperature and humidity of the environment. New coronavirus is sensitive to heat and ultraviolet light, and can be inactivated in 30 minutes at 56 degrees Celsius. The use of 75% ethanol, chlorine disinfectants, peracetic acid, chloroform, etc. can also effectively inactivate the virus. In daily life, alcohol and chlorine disinfectants can be used to disinfect the surface of objects and the environment.
