Wine is not a substitute for alcohol disinfection, and wine cannot effectively kill or inactivate the new coronavirus. The disinfection effect of alcohol is related to the concentration of alcohol dispensing, which requires the use of 75% sterilizing alcohol for sterilization or disinfection for the best effect and the concentration of medical sterilizing alcohol. Since 75% alcohol can better penetrate into the bacteria or viruses, thus making its dehydration, denaturation of protein coagulation play a disinfection role. If the concentration is lower than 75%, at this time the permeability of alcohol and coagulation protein ability is limited, so that the sterilization ability of alcohol will also be affected. The concentration of ethanol in wine is low, generally its concentration does not exceed 65%, when the sterilization and sterilization effect is significantly reduced. In addition, wine contains a variety of organic components, which is not conducive to disinfection will also breed bacteria, so it is usually not recommended to use wine instead of 75% of medical alcohol disinfection.
