"Drinking Baijiu to sterilize can prevent COVID-19" was once believed by many people. The logic of these people is that "viruses are afraid of alcohol, and people who drink every day are not easy to be infected". So can drinking really prevent COVID-19 infection? Of course not! Not only can COVID-19 not be prevented, but drinking will also aggravate the symptoms after "Zhongzhao'er". Alcohol is a commonly used disinfectant. 75% of alcohol can be used externally to kill viruses, but this is different from drinking. When drinking Baijiu, it is mainly absorbed in the gastrointestinal tract in the body. Through liver and kidney metabolism, there is no contact with COVID-19 that infects the respiratory tract. And drinking Baijiu could not kill the virus by 75% alcohol. Moreover, long-term drinking has various effects on the immune system and respiratory system, which will increase the risk of infection with COVID-19. "Drinking every day", some of these people have begun to get sick - "alcohol dependence syndrome". Alcohol addiction will lead to the inability to stop drinking. After stopping or reducing drinking, there will be alcohol withdrawal symptoms such as shaking hands, panic, sweating, and even life-threatening in serious cases. After COVID-19 infection, most people will experience fever, fatigue, dry cough, etc. Some people who have been drinking for a long time will stop or reduce drinking, and abstinence symptoms will appear one day later, or even several hours later. In addition, patients who drink alcohol for a long time are more likely to have problems due to the long-term impact of alcohol. Both the burden of alcohol metabolism in the liver and malnutrition caused by long-term drinking will affect the immunity of the body, aggravate the symptoms of COVID-19 infection and increase the probability of severe pneumonia. In this case, should we continue to drink? Of course not. When alcohol has reached the condition of dependence syndrome, only under the treatment and care of special hospitals can alcohol be safely given up. (Xinhua News Agency)
