Interpretive Summary: Avian influenza viruses are globally distributed, may produce highly contagious poultry disease, economically impact both large-scale and backyard poultry producers, and raise the specter of a human epidemic or pandemic. To help minimize adverse economic impacts and better anticipate the locations and times most susceptible to poultry outbreaks, we modeled the movement and behavior of a duck species that transports and transmits avian influenza viruses (AIV).
Technical Abstract: 1. Migratory waterfowl facilitate long-distance dispersal of zoonotic pathogens and are increasingly recognized as contributing to the geographic spread of avian influenza viruses (AIV). Avian influenza viruses are globally distributed, produce highly contagious poultry disease, economically impact both large-scale and backyard poultry producers, and raise the specter of human epidemic or pandemic. 2. Because migratory waterfowl behavior varies across multiple spatial and temporal scales, the timing and distribution of wild bird AIV introductions are also heterogeneous in time and space. To help reduce economic impacts to the poultry industry and enable poultry producers to better anticipate when and where poultry outbreaks may occur, it is critically important to consider the movement ecology of the waterfowl species that transport and transmit AIV. 3. We used high-resolution telemetry for a geographically widespread and common AIV host, blue-winged teal (BWTE) to model reservoir host movement states with respect to backyard and commercial poultry facilities in the United States. Our novel modeling framework enabled us to estimate wild bird proximity to poultry facilities while concurrently assessing the reciprocal correspondence of poultry facilities with BWTE movement. Our primary objective was to appraise the likelihood of duck and poultry contact by estimating when and where BWTE were geographically closest to poultry. 4. Our results indicate that BWTE proximity to poultry facilities varies by season, the poultry type produced (e.g., turkey, chicken), and if the facility is a commercial or backyard operation. These findings are broadly applicable to disease ecology research and can be applied by poultry producers to improve bio-security, enhance poultry management, and prioritize disease surveillance efforts.
