The emergence of avian inffllfluenza virus(AIVs)in seabird populations has intensiffiified in recent years,signaling a signiffiificant shift in host ecology and transmission dynamics.To address this,this study introduces the Terrestrial Bird-Seabird Co-occurrence Index(TSCI),a novel metric designed to assess the spatial and temporal cooccurrence between terrestrial bird and seabird AIV hosts.The TSCI demonstrates strong predictive performance(AUC=0.94),capturing over 84.10%of conffiifirmed seabirds AIV cases within global high-risk zones.Based on this,363 Mha of coastal wetlands(representing 2.44%of global land area)were identiffiified as high-risk terrestrial birds and seabirds contact interface,providing a robust tool for identifying high-risk zones of potential virus spillover at the“terrestrial birds and seabirds contact interface.”Our analysis highlights that temperate coastal regions,particularly in Europe,North America,and East Asia,exhibit high TSCI values.Wetland ecosystems serve as critical hotspots for virus spillover,emphasizing the need for habitat-speciffiific conservation and surveillance strategies.Our study offers a scalable tool to enhance targeted monitoring,guide resource allocation,and inform integrated policies for preventing zoonotic spillover from wild bird reservoirs under the One Health framework. 展开更多
