Swine Flu (Transmission, Symptoms & Prevention)

:: Swine Flu ::

What is Swine Flu?

Swine Flu, or Swine Influenza, is a respiratory illness in pigs caused by type A influenza virus that regularly causes flu in pigs. The viruses cause elevated levels of illness in the animals but yields a low death rate. Although the virus can happen year round, most incidences and outbreaks occur during the late fall and winter months, just like human influenza.

 

There are currently four identified main influenza type A viruses in pigs:

  • H1N1
  • H1N2
  • H3N2
  • H3N1

The most recently isolated influenza viruses from pigs have been the H1N1 viruses. The first classical swine flu virus, which is influenza type A H1N1 virus, was first identified in a pig almost 80 years ago, in 1930.

 

How Does the Flu Infect Humans?

Although most Swine Flu does not normally infect humans, sporadic human infections with swine flu do happen. Usually, transmission occurs in people with direct exposure to pigs. Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people. The most recent outbreak is of concern because there have been documented cases of one person spreading swine flu to others.
