Swine influenza (swine flu) is caused by an influenza virus type flu and pigs. Cause regular outbreaks of swine flu influenza viruses in pigs, but death is rare. The virus can be spread to pigs throughout the year, but outbreaks occur later in autumn and winter months similar outbreaks in people. The classical swine flu virus (a type of influenza A virus H1N1) was the first of several pig in 1930.
Like people, pigs can get influenza (flu), but the swine flu virus flu virus does not like people. Swine flu is not often infecting humans, and the rare cases that have occurred in the past have mainly affected people who had direct contact with pigs. But the current outbreak of swine flu is different. This is caused by a new swine flu viruses are spread by people - and this happens to people who have no contact with pigs.
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.
Note: swine influenza virus is not transmitted through food. You can not get influenza from pigs eat pork or pork products
