According to current research on the new coronavirus, the new coronavirus is heat-intolerant and cold-loving, and around 4°C is its optimal temperature for reproduction. -60℃ can survive for several years, so it is less likely to freeze it to death. It can usually be killed by heating, e.g. 56°C, for 30 minutes. This suggests eating cooked food, not raw food, in your diet, which facilitates the elimination of the coronavirus. To destroy the coronavirus, you can also use 75% alcohol to destroy the vesicle membrane of the virus. You can also use chlorine-based disinfectants such as 84 and Kenzin. The new coronavirus is intolerant to ultraviolet light, and can usually be effectively killed by the ultraviolet lamps in the hospital clinic, or the ultraviolet disinfection device at home, which is usually shone for about ten minutes when you are out of the house. So coronaviruses are afraid of heat and not cold, and it is impossible to freeze them to death. Source: Dr. Yurai
