It depends on the specific strain of "Swine Flu". The version that pigs get has probably been around for almost as long as there have been pigs. One version of swine flu in humans was identified in the 1930's. Another started in 1976. The pandemic version of H1N1/09 began in March 2009 and still circulates in outbreaks across the world but the pandemic of this strain has been declared over.
