Swine Flu: H1N1

Swine influenza, also called pig influenza, swine flu, hog flu and pig flu, is an infection caused by any one of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) is any strain of the influenza family of viruses that is endemic in pigs. As of 2009, the known SIV strains include influenza C and the sub-types of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. The Swine flu was initially seen in humans in Mexico in 2009.Six of the genes are very similar to the H1N2 influenza virus that was found in pigs around 2000. Swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is not common and does not always lead to human flu, often resulting only in the production of antibodies in the blood. If transmission does cause human flu, it is called zoonotic swine flu. People with regular exposure to pigs are at increased risk of swine flu infection.Signs and symptoms
