How long it takes for alcohol to destroy the Omicron virus depends on the actual situation. In general, alcohol at a concentration of 75% is effective in killing the new coronavirus in 1 to 2 minutes. Omicron virus is a mutated strain of the new coronavirus, although its spread, infectious, and the incubation period is shorter, but medical alcohol can also eliminate Omicron virus, the specific how long it takes according to the actual situation, because the temperature and humidity of different environments to eliminate the Omicron virus under the time and the effect is not the same. Alcohol can destroy omicron virus also depends on the degree of alcohol, if the concentration of alcohol is too low, although the alcohol can enter the virus, but can not solidify its internal proteins; and a high concentration of alcohol will be formed on the surface of the virus as a protective film, which prevents the alcohol from entering the body of the virus, therefore, only the concentration of 75% of the alcohol on the omicron has a better effect on the elimination of the omicron. It should be noted that medical alcohol also has a good combustion effect, so when using medical alcohol, must be away from open flames to avoid burning, fire and other accidents.
