Highly pathogenic avian influenza (HPAI) is a major global zoonosis. It has a complex ecological distribution with almost unpredictable epidemiological features thus placing it topmost in the World Organization for Animal Health list A poultry diseases. Structured questionnaire survey of poultry farmer's knowledge, attitudes, and practices (KAP) in two Nigerian states revealed the presence of risk farming practices that may enable avian influenza high chance of introduction/reintroduction. There existed significant statistical association between farmer's educational levels and AI awareness and zoonotic awareness (P < 0.005). Poultry rearing of multiage and species (81%), multiple sources of stock (62%), inadequate dead-bird disposal (71%), and access to live bird markets (LBMs) (62%) constituted major biosecurity threats in these poultry farming communities. Haemagglutination inhibition (HI) test detected antibodies against H5 avian influenza (AI) in 8 of the 400 sera samples; rapid antigen detection test kit (RADTK) was negative for all the 400 cloaca and trachea swabs. These results and other poultry diseases similar to AI observed in this study could invariably affect avian influenza early detection, reporting, and control. We recommend strong policy initiatives towards poultry farmers' attitudinal change and increasing efforts on awareness of the implications of future HPAI outbreaks in Nigeria.
高致病性禽流感(HPAI)是一种主要的全球人畜共患病。它具有复杂的生态分布,流行病学特征几乎不可预测,因此在世界动物卫生组织的A类家禽疾病名单中位居首位。对尼日利亚两个州家禽养殖户的知识、态度和行为(KAP)进行的结构化问卷调查显示,存在一些风险养殖行为,可能使禽流感有很高的传入/再传入几率。养殖户的教育水平与禽流感意识和人畜共患病意识之间存在显著的统计学关联(P < 0.005)。多龄和多品种家禽饲养(81%)、多种来源的禽苗(62%)、病死禽处理不当(71%)以及进入活禽市场(62%)是这些家禽养殖社区的主要生物安全威胁。血凝抑制(HI)试验在400份血清样本中的8份中检测到了针对H5禽流感(AI)的抗体;快速抗原检测试剂盒(RADTK)对所有400份泄殖腔和气管拭子检测均为阴性。这些结果以及本研究中观察到的其他与禽流感相似的家禽疾病,可能会对禽流感的早期检测、报告和控制产生影响。我们建议采取强有力的政策举措,改变家禽养殖户的态度,并加大力度提高人们对尼日利亚未来高致病性禽流感疫情影响的认识。
