Where is the disease found?
AI occurs worldwide and different strains are
more prevalent in certain areas of the world than
others.
Of particular interest are outbreaks of highly
pathogenic H5N1 AI that began in south-east
Asia in late 2003. Over the past years, several
other Asian countries have reported outbreaks
and in some, the disease is now considered to
be endemic (always present). Outbreaks of HPAI
H5N1 have also been reported in Africa and
Europe.
