Influenza viruses can infect people, birds, pigs, horses, seals, and other animals, but birds are infected with the greatest variety of influenza viruses. Swine flu is a respiratory disease that typically infects pigs. The new pandemic A/H1N1 (2009) virus, which may have originated from swine flu viruses, is of concern because it is highly contagious among people. History of Pandemic Influenza Virus A/H1N1 (2009) The origin of the current pandemic H1N1 virus is the subject of intense scientific debate. The pandemic H1N1 (2009) virus infection in humans is caused by a new A/H1N1 virus with shared genetic material from influenza viruses that typically affect pigs. Some of the genetic material of the pandemic H1N1 (2009) virus may even have an avian source, and according to a .” href=”http://www.sciencedaily.com/releases/2009/04/090430111640.htm” target=”_blank”>May 2009 study in the Journal of Virology, the current H1N1 virus is traceable to the .” href=”http://1918.pandemicflu.gov/” tar
