Like all flu viruses, swine influenza viruses constantly change. Pigs can be infected by avian, human and swine influenza viruses. When influenza viruses from different species infect pigs, the virus re-assort and May to appear before a mix of pig, human and / or avian influenza virus. Over the years, different variations of swine influenza viruses have emerged. Currently, there are four types of influenza virus subtypes that couple of pigs: H1N1, H1N2, H3N2 and H3N1. However, some more recent influenza viruses from pigs are H1N1 viruses.

Swine influenza viruses do not usually infect humans. However, the occasional human infections with swine flu have occurred. More generally, these cases occur in people with direct exposure to pigs, such as children near the pigs in a right or workers in the swine industry.

As documented case of a person spread of swine flu to others. In 1988, an outbreak of swine flu infection in pigs in visible Wisconsin resulted in more people infected, and though no explosion resulted in the community, had antibody evidence of virus transmission from patients to health care workers in contact closely with patients.
