New avian influenza strain detected in Nigeria

Nigeria 12 August, 2008 FAO: A strain of highly pathogenic avian influenza previously not recorded in sub-Saharan Africa has been detected in Nigeria.
Laboratory results from Nigeria and an FAO reference laboratory in Italy show that the newly discovered virus strain (H5N1, clade 2, EMA3) is genetically different from the strains that circulated in Nigeria during earlier outbreaks in 2006 and 2007. The new strain has never been reported before in Africa; it is more similar to strains previously identified in Europe (Italy), Asia (Afghanistan) and the Middle East (Iran) in 2007.
