Alcohol consumption has no preventive effect on novel coronavirus infection. Although the current research on the physical and chemical properties of the novel coronavirus has confirmed that the virus is sensitive to 75% ethanol and can be inactivated with it, it is limited to the direct interaction between the two in the outside world, and the in vivo effect is not yet known. Under normal circumstances, the high level of liquor on the market does not reach 75 degrees, even if the high concentration of liquor also has the effect of inactivating the virus, but after drinking, in the dilution of gastric juice and food, the concentration will be further reduced, and will soon be metabolized and decomposed into acetaldehyde and water, losing the role of inactivating the virus. In addition, a large amount of alcohol is not good for human health, it is likely to reduce the body’s resistance, more likely to lead to the invasion of the virus, during the epidemic rampant, should pay attention to the diet reasonable health.
