    In early January 2006, the first confirmed oubreaks of avian influenza in domestic birds occurred in the commercial chicken flocks in Kaduna, Jos and Kano States in the northern part of Nigeria. The outbreaks were confirmed to be the highly pathogenic avian influenza (HPAI) caused by the subtype H5N1. The outbreak was spontaneously reported in Jos, and about 10 days later it was reported in Kano and it quickly spread to other parts of the country. The infection was characterized by very high mortality in commercial layers. It was also observed to affect turkeys, broilers, cockerels, backyard/local chickens, ostriches, pigeons, guinea fowls, geese and ducks. The gross and microscopic lesions were found to similar to what have been described earlier for the disease.

    Outbreak of Highly Pathogenic Avian Influenza in Local Chickens in Nigeria
    (Vom Journal of Veterinary Science, 2006) Kumbish, Peterside; Jambalang, Alex; Damina, M; Hussaini, Bakare; Oyetunde, I; Akanbi, Olatunde; Jwander, L; Danbirni, I; Elisha, I; Solomon, P; Woma, T; Bako, B; Nanbol, I; Chukwukere, S; Ardo, A; Bunshia, S
    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.
