Ditto that, GW. We're stocking up on Vitamin C, super anti-oxidant tablets, B vitamins, and a good supply of a daily multi for both us and the children. An illness like smallpox or flu or something like that which is highly contagious is more likely caught by people who are run down or in generally weaker health, anyway. We've also got several bottles (I keep one in my purse) of no-wash antibacterial gel, and I make the kids use it after we've been anywhere, like Target to look at toys (picking up things that perhaps a sick kid has touched) or to the park (sliding their hands along the same rails other kids have used)--and always before we eat out. Keeping hands clean, turning your head away from a cougher or sneezer, avoiding touching a lot of public-access rails and door panels (or using antibacterial gel immediately after)--lots can be done to protect self and loved ones. And start by keeping your immune system healthy!!!
