Soap and running water aren't always available, so carry antibacterial gel as a backup. It doesn't kill all germs, however, so don't use it exclusively. The CDC recommends using a gel with at least 60 percent alcohol. When using antibacterial gel, rub hands together to spread the gel over palms and fingers until skin is dry.
Did you know that Cold and Flu viruses can survive on hard surfaces for up to 18 hours. To reduce the amount of germs you come into contact with in public, hand-sanitizing wipes are a good option. Use them to clean shopping cart handles, door knobs, elevator buttons and restaurants and counter-tops. All ranked high on the list of places where bacteria reside.
