There are currently no drugs licensed for the treatment or prevention of COVID-19 and alcohol does not kill novel coronavirus.
The World Health Organisation suggested to frequently clean hands with an alcohol-based hand rub or wash them with soap and water. It also mentions that spraying of alcohol to the body does not kill the coronavirus which has already entered your body.
The World Health Organisation in a tweet on 8 February 2020 posted a graphic image recommending the public that drinking alcohol does not protect from coronavirus infection. People who do not drink alcohol should not start drinking in an attempt to prevent coronavirus infection.
Also, the Centers for Disease Control and Prevention has confirmed that there is no vaccine and no specific antiviral medicine to prevent or treat coronavirus.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
