Swine flu is a highly contagious disease that spreads from pigs to humans after contact. Spread through droplets from sneezing and coughing, swine flu can cause mild, moderate, or severe symptoms. Besides sneezing and coughing, swine flu can also spread through contact with surfaces touched by infected individuals.

The important thing with swine flu is protection against and prevention of infection. The primary ways to do this are to get a flu vaccine and avoid close contact with anyone you suspect might be infected.
