There are several methods to kill the new coronavirus: 1) physical methods, such as high temperature, because the coronavirus can only survive for 30 minutes at 56°C, so it will soon be inactivated under high temperature; ultraviolet light, which can denature the protein and RNA, thus inactivating it; 2) chemically, disinfectants containing chlorine, 75% alcohol can denature the protein, thus inactivating the virus; 3) medically, therapeutically, vaccines can also be inactivated. After the virus is isolated and made into a non-toxic virus, it is implanted into the human body, and after it is implanted into the human body, the human immune system is activated, and after the immune system is activated, it will produce antibodies against the virus. Therefore, the vaccine is an in vivo treatment for the virus. The method used in vitro is to kill the virus mainly by physical and biological methods. Content source: Dr. Yurei
