You cannot get H1N1 flu virus from eating pork or any other food, drinking water, swimming in pools, or using hot tubs or saunas.
Any flu virus can spread from person to person when:
- Someone with the flu coughs or sneezes into air that others breathe in.
- Someone touches a doorknob, desk, computer, or counter with the flu virus on it and then touches their mouth, eyes, or nose.
- Someone touches mucus while taking care of a child or adult who is ill with the flu.
Symptoms, diagnosis, and treatment of H1N1 influenza are similar to that for the flu in general.
