Abstract:
Highly Pathogenic Avian Influenza (HPAI) is a viral disease affecting the digestive, nervous and respiratory systems of all domestic and wild birds that is characterized by respiratory, reproductive, digestive and/or nervous signs with high morbidity and mortality. Following the first report of Avian Influenza (AI) in Nigeria in January ۲۰۰۶ and its subsequent confirmation in February ۲۰۰۶, this study was designed to Retrospectively Review the Spatio-Temporal spread of HPAI in and around Maiduguri, Borno State, Nigeria. Out breaks were recorded from six (۶) farms within Maiduguri and its environs, the index case of AI in Maiduguri was noticed on the ۱۱th November, ۲۰۰۶ and was reported on the ۱۳th November, ۲۰۰۶. Subsequent transmission from the index case could have been through aerosol or contaminated dust in the direction of wind flow as occasioned by the prevailing harmattan period which coincides with the outbreak period between November ۲۰۰۶ and January ۲۰۰۷. An age-specific mortality rate of ۳۳.۷% was recorded among birds of age group ۰- ۳۰ weeks, while ۵۳.۱% among the age group ۳۱-۶۰ weeks and ۴۴.۱% was recorded among adult birds of unknown age group. It is recommended that there should be improved management practices, which include strict enforcement of biosecurity measures to reduce human and fomite contacts risks that could occur without observing or breach of biosecurity protocols. Improve litter and other poultry waste management, exclusion of other animal species on poultry farms, and institution biosecurity against risks from neighbourhood farms’ activities.Highly Pathogenic Avian Influenza (HPAI) is a viral disease affecting the digestive, nervous and respiratory systems of all domestic and wild birds that is characterized by respiratory, reproductive, digestive and/or nervous signs with high morbidity and mortality.
