Alcohol is effective against Neocoronaviruses, but requires 75% alcohol. Alcohol is able to inactivate NeoCoronavirus but requires a concentration of 75% alcohol, which is highly penetrative and is able to penetrate into bacteria and viruses, denaturing the proteins within the bacteria and viruses and causing them to die. Too high a concentration of alcohol will cause the surface of the bacteria to coagulate and form a hard film, preventing the alcohol from penetrating further into the virus and affecting its effectiveness. Too low a concentration of alcohol will not denature the proteins within the pathogenic bacteria and will not achieve the purpose of killing. In addition to alcohol, the new crown virus is also very sensitive to ultraviolet light and high temperature, 56 degrees Celsius for 30 minutes, ether, chlorine disinfectants, peracetic acid, chloroform can effectively inactivate the new crown virus. When it is necessary to disinfect a large area of the environment, it is not advisable to use alcohol to disinfect the environment due to its volatility. Chlorine-containing disinfectants can be used to disinfect large areas of the environment to inactivate the new coronavirus.
