However, strains such as H5, and H7 are extremely contagious among birds, and can kill domesticated birds such as chickens, ducks, and turkeys. The virulent form of the ‘bird flu’ virus that is grabbing the headlines, is known simply as H5N1.

Infected birds carry the “flu” virus in their saliva, nasal secretions, and excrement.

Domesticated birds may become infected with the ‘bird flu’ virus through direct contact with infected wild birds or other infected poultry, or through contact with surfaces (such as dirt or cages) or materials (such as water or feed) that have been contaminated with the virus.

Humans can catch the disease through constant close contact with infected birds or...
