CDC\Cynthia Goldsmith

Influenzas, commonly referred to as "the flu," are contagious diseases caused by influenza viruses, types A, B, or C. Influenza Type A viruses, with varying degrees of virulence, can infect humans, birds, pigs, horses, and other animals. Type B influenza viruses normally infect only humans, but have not caused pandemics (global outbreaks of disease). Type C influenza viruses cause only mild illness in humans.
