What is H1N1 - Swine Flu

H1N1 was first observed in Mexico. The Mexican government closed most of Mexico City's public and private offices and facilities to try to contain the spread of the virus but it was too late and the virus quickly spread globally. On June 11, 2009, WHO declared the outbreak to be a pandemic.

What is Swing flu?

  • Swine flu (swine influenza) is a respiratory disease caused by viruses that infect the respiratory tract of pigs and result in nasal secretions, a barking-like cough, decreased appetite, and other kinds of behavior.
  • Swine flu produces most of the same symptoms in pigs as human flu produces in people.
  • Swine flu can last about one to two weeks in pigs that survive.
  • Investigators think the 2009 swine flu strain, first seen in Mexico, should be termed novel H1N1 flu since it is mainly found infecting people and exhibits two main surface antigens, H1 (hemagglutinin type 1) and N1 (neuraminidase type1).
