Alcohol is a powerful disinfectant and can be used to kill germs, including those that cause the COVID-19 pandemic. Rubbing alcohol, when diluted with water or aloe vera, can be used to make a hand sanitizer that is effective against SARS-CoV-2, the virus responsible for the pandemic. To be effective, the alcohol concentration should be around 70%. However, this general rule depends on the virus in question.
Viruses with an envelope structure, such as the common cold and coronavirus, can be broken down with alcohol solutions of 60% or more. But there are other viral structures, such as norovirus, that cannot be killed with any concentration of alcohol. That's why hand washing is the most effective method to eliminate all forms of viruses and bacteria.
