To prevent the spread of germs, including COVID-19, CDC recommends washing hands with soap and water whenever possible because it reduces the amount of many types of germs and chemicals on hands. (Act of washing does not kill the virus but washes it off)
But if soap and water are not readily available, using a hand sanitizer with at least 60% alcohol can help you avoid getting sick and spreading germs to others.
Alcohol is the active ingredient that kill the germs {bacteria or virus)
unlike a whole bunch of trumpian indians must not ingest alcohol to sanitize your innards but use it externally it has to be 60% any less is ineffective
The most important point to remember:
In no way will consumption of alcohol protect you from COVID-19 or prevent you from being infected by it.
