Swine flu

Swine influenza also known as swine flu, flu Mexico, swine influenza, swine flu and is an infection of a host animal by any of several types of flu virus. In 2009, the media labeled as "swine flu" caused by influenza in 2009 a new strain of swine fever virus A/H1N1 origin as it was already known as "avian flu" influenza caused by the recent Asian Linage highly pathogenic (HPAI) strain H5N1 that is still endemic in many species of wild birds in several countries. A virus of swine influenza (SIV) is a strain of the family of flu viruses, which is usually provided by (endemic in) pigs. Starting from 2009, strains of SIV known are the C and influenza virus subtypes of influenza A virus known as H1N1, H1N2, H3N1, H3N2 and H2N3. Swine influenza is common in pigs in the United States (particularly in the Midwest and occasionally in other states), Mexico, Canada, South America, Europe (including the United Kingdom, Sweden and Italy), Kenya and East Asia (namely China, Taiwan and Japan).

Transmission of influenza viruses of swine fever to humans is not common and not always because of human influenza, often results in the production of antibodies in the blood. The meat of the animal poses no risk of transmitting the virus when it is properly cooked. If the transmission does not cause human influenza, it is called zoonotic swine influenza. People who work with pigs, especially those with intense exposure are at increased risk of contracting swine influenza. In the mid-20th century, the identification of subtypes of influenza is possible, allowing a precise diagnosis of transmission to humans. Since then, fifty confirmed transmissions were recorded. Rarely, these strains of swine influenza can be transmitted from human to human. In humans, symptoms of swine influenza are similar to those of influenza and influenza-like illness in general, including chills, fever, sore throat, muscle aches, headaches, coughing, weakness and general malaise.

Transmission of influenza viruses of swine fever to humans is not common and not always because of human influenza, 2009. The outbreak of swine influenza in humans is caused by a new strain of influenza virus type A subtype H1N1, which contains genes closely related to swine influenza. The origin of this new strain is unknown. However, the World Organization for Animal Health (OIE) said that this strain has not been isolated from pigs. This strain can be transmitted from person to person, and causes symptoms of normal influenza.
Pigs can become infected with human influenza, and this appears to have happened during the 1918 flu pandemic and the 2009 swine flu outbreak.
