What type of virus is H5N1?
H5N1 is a highly pathogenic avian (bird) flu virus that has caused serious outbreaks in domestic poultry in parts of Asia and the Middle East. Since its widespread re-emergence in 2003, rare, sporadic human infections with this virus have been reported in Asia, and later in Africa, Europe, and the Middle East.
Where did H5N1 come from?
The avian influenza virus A(H5N1) emerged in 1996. It was first identified in Southern China and Hong Kong The A(H5N1) virus kills a high proportion of the poultry that it infects and is therefore known as a highly pathogenic avian influenza virus.
How did the avian flu spread?
Avian influenza is mainly spread by direct contact between infected birds and healthy birds It can also be transmitted when birds come in contact with equipment or materials (including water and feed) that have been contaminated with feces or secretions from the nose or mouth of infected birds.
