Viruses are afraid of high temperature because the temperature increases protein denaturation, and after protein denaturation, RNA and DNA can be denatured and the virus is killed. So high temperature can make the virus is inactivated. For this time the new coronavirus, characterized by a temperature of 56 ℃, can only survive 30 minutes. According to this mechanism, high temperature can be used to make the virus inactivated. For example, if you suspect that your clothes are contaminated with the virus, you can kill the virus by soaking them in hot water for more than half an hour, in addition to using disinfectant.
