There are two main types of influenza virus: types A and B. The influenza A and B viruses that routinely spread in people (human influenza viruses) are responsible for seasonal flu epidemics each year. Over the course of a flu season, different types (A & B) and subtypes (influenza A) of influenza circulate and cause illness. Influenza A viruses are also found in many different animals, including ducks, chickens, pigs, whales, horses and seals while Influenza B viruses circulate widely only among humans.
