New coronavirus refers to the new coronavirus, the new coronavirus “fear of heat is not afraid of cold”. New coronavirus is sensitive to high temperature, usually, in 56 ℃ high temperature disinfection for about 30 minutes, can effectively kill the new coronavirus. The new coronavirus can be inactivated in 30 minutes at a high temperature of 56°C. The higher the temperature, the shorter the survival time of the new coronavirus. In addition to high temperature environment, the new coronavirus is also sensitive to ultraviolet light, 75% alcohol and chlorine-containing disinfectant, so these methods can be adopted to disinfect and prevent the spread of the new coronavirus. The new coronavirus is not afraid of cold, the structure of the virus is more solid under low temperature and can survive for a long time in low temperature, on the contrary, the structure of the virus is unstable under high temperature, which will easily lead to structural changes and make the virus lose its vitality. It is recommended to do a good job of preventing and controlling the new coronavirus in daily life, wearing masks when going out, washing hands frequently, ventilating indoors, and disinfecting objects that often come into contact with the outside world.
