An infographic published by Compound Interest shows how hand sanitizers protect users from infections. Alcohol in hand sanitizers alter (denature) the structure of proteins. It destroys the cell wall and membranes of bacteria cells, and the envelope of viruses, including the coronavirus. Non-alcohol-based sanitizers also kill bacteria, but are less effective against viruses.

For this reason, alcohol-based sanitizers have enjoyed a boom. New manufacturers are joining the proverbial bandwagon by flooding the market with them. It is now like food, an essential item we cannot live without in our everyday lives. Yes, clean hands save lives.
