It should be noted, though, that hand washing is much more effective than using hand gel.
According to the Centers for Disease Control and Prevention (CDC): “Soap and water are more effective than hand sanitizers at removing certain kinds of germs, like Cryptosporidium, norovirus, and Clostridium difficile1-5.
“Although alcohol-based hand sanitizers can inactivate many types of microbes very effectively when used correctly, people may not use a large enough volume of the sanitizers or may wipe it off before it has dried.”
Sitting in the window seat can also help ward off sickness.
