Swine Influenza

Swine influenza was first proposed to be a disease related to human flu during the 1918 flu pandemic, when pigs became ill at the same time as humans. The first identification of an influenza virus as a cause of disease in pigs occurred about ten years later, in 1930. For the following 60 years, swine influenza strains were almost exclusively H1N1. Then, between 1997 and 2002, new strains of three different subtypes and five different genotypes emerged as causes of influenza among pigs in North America. In 1997–1998, H3N2 strains emerged. These strains, which include genes derived by Reassortment from human, swine and avian viruses, have become a major cause of swine influenza in North America. Reassortment between H1N1 and H3N2 produced H1N2. In 1999 in Canada, a strain of H4N6 crossed the species barrier from birds to pigs, but was contained on a single farm.

Swine Influenza can affect animals and also humans as well.

Swine Influenza causes fever, disorientation, stiffness of the joints, vomiting, and loss of consciousness. It can also end in death.

You can detect swine influenza by watching out for these symptoms; vomiting, nausea, runny nose, loss of appetite, drowsy, the chills, fever, body aches, soar throat, coughing, diarrhea, and stomach ache.

The treatment for Swine Flu contains bed rest, lots of healthy fluids, cough suppressants, and medicine for fevers.
