Re: what are some precautions i can take to avoid the swine flu?

Antiseptic wipes and hand cleansers would be a good idea since they will be in contact with other kids sharing items, shaking hands, etc. and will not always have access to water to wash their hands.

As far as supplements to help maintain their immune system I would focus primarily on vitamin C sources and zinc.

Andrographis is great if they actually come down with the flu.
