Author(s): Abduleziz Jemal Hamido* and Milion Shiferaw
Avian influenza viruses are now widely recognized as important threats to agricultural biosecurity and public health,
and as the potential source for pandemic human influenza viruses. Human infections with avian influenza viruses
have been reported from Asia (H5N1, H5N2, H9N2), Africa (H5N1, H10N7), Europe (H7N7, H7N3, H7N2),
and North America (H7N3, H7N2, H11N9). Direct and indirect public health risks from avian influenza are not
restricted to the highly pathogenic H5N1 “bird flu” virus, and include low pathogenic as well as high pathogenic
strains of other avian influenza virus subtypes, e. g., H1N1, H7N2, H7N3, H7N7, and H9N2. Research has shown
that the 1918 Spanish Flu pandemic was caused by an H1N1 influenza virus of avian origins, and during the past
decade, fatal human disease and human-to-human transmission has been confirmed among persons in.. View more»
