A(H1N1) Influenza ("Swine Flu")
In 2009, A(H1N1) influenza, also called "swine flu," spread to many countries. In April 2009, the analysis of samples collected in cases of flu symptoms by the U.S. and Mexican governments identified a new subtype of the Influenza A(H1N1) virus, classified as "A/CALIFORNIA/04/2009," which had not been previously detected in humans or swine. Influenza A(H1N1) is transmitted from one person to another mainly through coughing, sneezing and contact with nasal secretions from infected individuals. According to the WHO, there is no relation between those infected with Influenza A(H1N1) and contact with persons living near swine or the consumption of pork and pork-derived products.
