What are some good ways to stay healthy when the rest of your family is sick?

Wash, wash, wash. The number one way to keep from getting cold-type illnesses is frequent hand washing and avoiding handling what your sick family members have touched (door handles, keys, utensils, etc) if someone sneezes/coughs try to avoid being in the same room as them for a couple of minutes after the event. I am a fan of vit c and taking extra during the cold-flu months can help.
