Alcohol at a concentration of 75% is effective against omicron viruses.
Generally speaking, 75% alcohol can kill Omicron variant, alcohol has the effect of dehydration, when the new coronavirus touches 75% alcohol, 75% alcohol will absorb the water in the glycoprotein of the virus shell, so that the new coronavirus will be dehydrated, denatured coagulation, inactivation, and finally achieve the purpose of killing the virus.
Alcohol sterilization ability of the size of its concentration is directly related to the concentration of alcohol is too high or too low can not, the optimal concentration is 75%. The optimal concentration is 75%, because 75% of the alcohol and the osmotic pressure of the virus shell is similar, which can efficiently inactivate the virus and kill the virus.
If the concentration of alcohol is lower than 75%, then the permeability of alcohol will be reduced, thus directly affecting the sterilization ability of alcohol.
If the concentration of alcohol is higher than 75% (e.g. 95% alcohol), then the dehydration of alcohol for bacterial proteins will be too rapid, and then the bacterial surface proteins will be denatured and coagulated first, thus forming a solid envelope, which will lead to the alcohol instead of being able to penetrate into the bacterial interior well, and ultimately affecting the bactericidal ability of alcohol.
Prevent the invasion of Omicron, in addition to the use of alcohol, but also need to be vaccinated in a timely manner, as early as possible to complete the booster vaccination; minimize non-essential travel, in public places and take public transport more attention to the protection; wear a good mask to minimize exposure, and at home to pay attention to open the windows and ventilation.
