Highly pathogenic avian influenza H5N1 resurgence has occurred in Nigerian domestic bird flocks with public health concern. This study assessed poultry farmers' knowledge, perceptions, and biosecurity and biosafety practices regarding H5N1 resurgence, explore risk pathways for viral dissemination and associated socio-cultural and economic drivers in poultry flocks in Nigeria. A cross-sectional survey was carried out in randomly selected two poultry production systems, commercial intensive poultry production system and the backyard traditional free-range poultry production system. A One Health framework model was conceptualized to assess inter-links of biophysical, environmental, and sociocultural activities that interface to drive resurgence for better interventions. Descriptive and analytical statistical analyses were performed at 95% confidence level. Of the 422 recruited poultry farmers, 98.6% (n = 416) participated. Majorities of smallholder commercial farmers (93.5%) and backyard poultry keepers (97.7%) engaged in intensive and extensive management, respectively. Identified significant zoonotic risk pathways for H5N1 virus spread were through consumption of undercooked poultry meat and products, and contacts with infected birds and contaminated fomites. Separation of sick birds from apparently healthy ones, frequent cleaning and disinfection of equipment and premises, movement control of birds to nearby water bodies, use of personal protective equipment, and movement control of persons and vehicles into the flock settlements were significantly practiced biosecurity measures. Presence of nearby water bodies (ponds) close to flock settlements (p < 0.001), frequent contact of wild and domestic birds (p < 0.001), cultural practice of bird exchange between flocks (p < 0.001), and wild waterfowls' seasonal migrations (p < 0.001) significantly influenced resurgence. Understanding determinants interactions in the 'Conceptual One Health framework model' is required for better intercontinental intervention against HPAI H5N1. Reform of socio-cultural and economic activities using One Health approach will not only assure food safety and food security, but also guarantee public and environmental health.
