Causes of Swine Influenza

Main Causes For the Swine Influenza Outbreaks

Generally swine flu or swine influenza does not affect human population, but the recent outbreak is obviously not solely due to swine influenza virus. The swine influenza causes and its epidemic left many countries like US and other global areas in a great state of confusion and uncertainty. But by the end of 2009, it has been identified as a new Influenza A virus which is further characterized by most common subtypes H1N1, H1N1, H1N2, H3N1, H3N2, and H2N3. This classification of various subtypes mainly depends upon the types of proteins or antigens called Hemagglutinin (H) and Neuraminidase (N) that exists on the outer surface of the virus.

Swine Influenza Causes

  • One of the main swine influenza causes that resulted in the huge outbreak all over the world in 2009 is H1N1 virus. It is termed as novel H1N1 flu as it contains the influenza virus that changes or mutates constantly resulting in many strains of H1N1 which differ deviously from each other. The existence of different swine influenza strains is due to the genetic re-assortment containing pieces of influenza from many different sources such as birds, pigs and human influenza viruses.
  • The swine influenza causes which results in ordinary flu symptoms like fever, cough, sore throat, headache, chills and tiredness occurs mainly because of easy spreading of virus from one person to another. It is highly contaminating and the transmission of virus takes place easily by the direct contact with surfaces of respiratory secretions.

Cure for Swine Influenza

  • As humans have very less immunity to this new strain of viruses, it is very important for every individual to realize the swine influenza causes and follow necessary precautions to avoid it. The world health organization has announced this as pandemic and insisted on taking vaccinations to prevent the swine influenza causes and its symptoms.
  • The Centers for Disease Control and Prevention (CDC) is currently recommending antiviral drugs as a treatment for mild symptoms of swine influenza. The precautions and remedies prescribed by CDC are worth following because they target the origins of swine influenza causes and help in reducing the risk factors and serious illnesses.
