Can using hand sanitizer prevent cold?

Maybe/not: Upper respiratory viruses including a cold can be passed in both contact to the germ on surfaces & airborne droplets. Hand washing is a bit more successful in removing germs than sanitizers but they can cut down exposure risk. Some cultures routinely ware mouth/nose covering asks to reduce airborne virus risk when in public. I doubt this will catch on here.

It Helps: Frequent hand washing,getting your flu shot,not sharing utensils,straws,etc all help and Hand sanitizer is an adjunct to hand washing as well as exercise and a good balanced diet to keep up your immune system.
