Avian Influenza H5N1 in Egypt: What we Know and What we have to Know?
...reaks of avian influenza viruses (AIV) of subtype H5N1 in poultry since 2008. Since then, these viruses continue to evolve. In 2006-2008, outbreaks were reported mostly during the winter season, but in 2009-2012 they occurred year round. H5N1 AIV succeeded in infecting not only domesticated birds but also many other avian species and mammals. Infections of humans were accompanied by mutations in the hemagglutinin (HA) protei...
