Avian Influenza (Bird Flu) – Finding Information
Influenza viruses are
classified as types A, B and C and they are found in a very large number of
different species of birds and mammals, including humans. In addition to man,
influenza A viruses cause natural infections in birds while influenza B and C
types usually affect humans. Influenza A viruses are also frequently isolated in
pigs and horses. Wild birds are thought to be the source of spread of influenza
A viruses to all other animals. Wild birds often carry the disease without
becoming sick. All influenza viruses have the ability to mutate, and scientists
are concerned by the fact that the
A/H5N1 virus is now
able to infect humans. Influenza pandemic is the term used for a serious human
influenza epidemic, more severe than the normal seasonal outbreaks that occur
almost every year. Pandemics are fairly rare, the last worldwide one being in
1968 (Hong Kong flu). They are caused by a new virus emerging against which
humans have no immunity, resulting in transmission and multiple outbreaks across
the globe. At this point, it is believed that most cases of bird flu infection
in humans have resulted from direct contact with infected poultry or
contaminated surfaces.
