Abstract
Highly Pathogenic Avian Influenza (HPAI) is a highly contagious viral diseases affecting the digestive, nervous, respiratory and /or reproductive systems of all domestic and wild birds. The outbreaks in local/backyard chickens were reported in 5 States (Jigawa, Kano, Nassarawa, Katsina, and Taraba). In this paper, we describe the clinical and pathological findings in local chickens during the outbreak of HPAI caused by H5N1 subtype in Nigeria and compared them with those reported in other parts of the world. The disease in local chickens in Nigeria was found to show little or no clinical signs and gross lesions. This was possible due to the fact that the birds died per acutely before signs or lesions could develop.
