History of the Bird Flu

  • First infected humans in 1997 during a poultry outbreak in Hong Kong SAR, China. 

  • The virus has spread from Asia to Europe and Africa and has become entrenched in poultry in some countries, resulting in millions of poultry infections.

  • The most recent out break of the virus was in February 2004

  • There are two different strains of the virus, A(H5N1) and A(H7N9)

  • The A(H7N9) virus particularly affects people with underlying medical conditions.

  • In many patients, the disease caused by the A(H5N1) virus follows an unusually aggressive clinical course, with rapid deterioration and high fatality. Like most emerging disease, A(H5N1) influenza in humans is not well understood.
