What is Influenza Virus? Can it cause death?

• Influenza viruses have been around for a very
  long time Hippocrates wrote the first account of
  the illness brought on by the virus in 412 BC.
  Since then, influenza viruses have been observed
  to infect a wide range of animal species in
  addition to humans.
• Occasionally, the virus jumps across various
  animal species with disastrous results. The
  symptoms of this viral infection include nasal
  discharges, chills, fever, lack of appetite,
  weariness, and diarrhoea in addition to an
  infection of the host's upper and lower
  respiratory tracts.
• The four subtypes of the influenza virus are A,
  B, C, and D. Seasonal flu is known to be caused
  by both influenza A and B, but only influenza A
  is to blame for pandemics.

• Sneezing, coughing, and close contact with an
  infected individual are all ways to catch the
  highly contagious influenza A(H1N1) virus.
• The symptoms of influenza A(H1N1) are strikingly
  similar to those of the common flu. Symptoms
  often show up 3 to 5 days after the virus has
  been exposed.

  pork products will not spread influenza A(H1N1).
