    What is Bird flu?

    Avian influenza (also known as bird flu, avian flu, influenzavirus A, type A flu, or genus A flu) is a type of influenza virus that is hosted by birds, but may infect several species of mammals. It was first identified in Italy in the early 1900s and is now known to exist worldwide. A strain of the H5N1-type of avian influenza that emerged in 1997 has been identified as the most likely source of a future influenza pandemic.

    Avian influenza viruses compose the Influenzavirus A genus of the Orthomyxoviridae family and are negative sense, single-stranded, segmented RNA viruses. “Influenza viruses are further categorised into subtypes according to the antigens of the haemagglutinin (H) and neuraminidase (N) projections on their surfaces. There are 14 haemagglutinin subtypes and 9 neuraminidase subtypes of influenza A viruses, and AI [avian influenza] viruses have representatives in all of these subtypes. However, to date all highly pathogenic AI [avian influenza] viruses that cause generalised rather than respiratory disease belong to either the H5 or H7 subtypes. For example, the classical fowl plague virus is H7N7 and the virus responsible for the major epidemic in the eastern United States in 1983 84 was H5N2” Avian Influenza
