“…In Africa, despite reports on the genetic/biological constituents/properties of HPAI H5N1 viruses of African origin (Ducatez et al, 2006(Ducatez et al, , 2007Njouom et al, 2008;Couacy-Hymann et al, 2008;Cattoli et al, 2009;Fasina et al, 2009), the epidemiologic aspects of HPAI H5N1 virus infection in poultry have not been investigated. Although previous studies have provided an epidemiologic framework for investigation of risk factors for HPAI H5N1 virus in poultry (Henzler et al, 2003;Thomas et al, 2005;Bouma et al, 2009;Busani et al, 2009), study findings and proposed prevention strategies may not apply to the conditions of Nigeria in view of variations in climatic conditions, poultry practices, and the socioeconomic and cultural orientations of agricultural populations in this geographic region.…”
