About Avian influenza (AI)
- AI commonly called bird flu is an infectious viral disease of birds and is zoonotic disease.
- It is an infectious viral disease of birds and can sometimes spread to domestic poultry and cause large-scale outbreaks of serious disease.
- AI viruses are divided into 2 groups based on their ability to cause disease in poultry:
- (i) high pathogenicity: Viruses result in high death rates up to 100% mortality within 48 hours in some poultry species.
- (ii) Low pathogenicity: Viruses are not generally associated with severe disease but causes outbreaks in poultry.
- Human Infections: Most avian influenza viruses do not infect humans however A(H7N9) and A(H5N1) virus strains have caused serious infections in people.
- However, infections in humans have been associated with direct or indirect contact with infected live or dead poultry.
- Note: There is no evidence that the disease can be spread to people through properly cooked food. Controlling the spread of disease in animals is the first step in decreasing risks to humans.
