swine flu 1

A very common known disease since 2009. The word swine is used as in the earlier times, people who caught this disease used to have direct contact with pigs and get affected by the influenza virus. Therefore, it was believed that this disease was caused by some virus linked with pigs. Later, this belief changed as people who were not having any contact with pigs, showed signs of infections caused by the H1N1 virus.

In 1930, for the first time, pork producers recognized the influenza virus in pigs. People who were associated with pigs caught that virus as well.

Nasal secretions, barking cough, decreased appetite and change in behavior were the symptoms noticed in the infected swine. Later the virus was seen in humans in 2009, Mexico.

A respiratory disease which is caused by influenza virus and infects the respiratory tract of the pigs is known as Swine Flu. The influenza virus is stably adaptable to humans. Therefore, it can be transmitted easily from animals to humans.

In 2009, a case of swine flu was registered in Mexico, due to the infection caused by the H1N1 virus: H1 (hemagglutinin type 1) and N1 (neuraminidase type 1).

It is called Swine Flu because the eight RNA strands from novel H1N1 flu derived from one strand of human flu strains, two from bird strains and five from swine strains.

In 2011, influenza An H3N2v virus was also reported for the cause of swine flu.

  • H1N1v Influenza Virus
  • H3N2v Influenza Virus
  • H1N2v Influenza Virus
  • H3N2 Influenza Virus
