It is not true that proper alcohol consumption prevents new crown. Drinking alcohol can not prevent new crown pneumonia, and long-term drinking will affect the body’s immune function, increasing the risk of infection. Medical alcohol and liquor are two completely different concepts, drinking alcohol can not let the alcohol directly on the virus, once drinking alcohol caused by the body damage is even more unfavorable to prevent the virus attack. At present, the most effective way to prevent the new crown is to complete the new crown virus vaccination. The second is to do a good job of personal protection measures, consciously wear a good mask, wash your hands regularly, and others to maintain a certain distance. It is recommended to maintain a good lifestyle, moderate exercise, balanced nutrition, adequate sleep, a positive and optimistic mindset, and improve one’s immunity. The use of ultraviolet light, chlorine disinfectants, ether, 75% ethanol, peroxyacetic acid and chloroform and other fat solvents can effectively inactivate the virus. Do not blindly believe that drinking alcohol can prevent the new crown.
