Influenza not only affects humans but they also infect other animals such as pigs and turkey. Not only that, but it easily crosses species. Thus, new viruses are probably created in pigs and water fowl like ducks and seagulls and then later passed on to other creatures. For example, in 1980, the virus produced an epidemic in seals and caused conjunctivitis in humans who tried to help. The influenza virus can also last for hours in dried mucus.
