Avian influenza spillover into poultry: environmental influences and biosecurity protections

Share:

"Highlights:

  • Integrated case-control and spatial data to assess biosecurity efficacy in context of local risk.
  • Human-mediated transmission pathways contribute to avian influenza spillover into poultry.
  • On-site vehicle decontamination and providing restroom facilities reduced spillover risk.
  • Litter decontamination treatments and avoiding shared dead-bird disposal sites reduced risk."
