Until this has been successful in the quarantine of 4 sub-type A: H1N1, H1N2, H3N2, and H3N1. H1N1 is a new type of virus that recently found in the pigs.
Swine flu virus normally does not actually infected with the human. However, the existence of sporadic infections are reported this virus in humans, as happened in the U.S. and mexico. Often people who are exposed to people who work on the farm / industry related to the pigs. Also reported the existence of the spread between humans.
CDC reports first receive only 1-2 cases of flu this every 1 to 2 years. but since December 2005 until February 2009, 12 cases have been reported. Even in April 2009 reported the incident occurred outside the normal (break out).
