Factory farming and long-distance live animal transport apparently led to the emergence of the ancestors of the current swine flu threat.

A preliminary analysis of the H1N1 swine flu virus isolated from human cases in California and Texas reveals that six of the eight viral gene segments arose from North American swine flu strains circulating since 1998, when a new strain was first identified on a factory farm in North Carolina.

This genetic fingerprint, first released by Columbia University’s Center for Computation Biology and the Institute for Advanced Study in Princeton,[1] has now been reportedly confirmed by researchers at the University of Edinburgh, St. Jude's Children's Research Hospital and virologist Ruben Donis, chief of the molecular virology and vaccines branch at the U.S. Centers for Disease Control and Prevention. Dr. Robert Webster, the director of the U.S. Collaborating Center of the World Health Organization, and considered the "godfather of flu research,"[2] is reported as saying "The triple reassortant in pigs [first discovered in the U.S. in 1998] seems to be the precursor." the rest
