Abstract:
Migratory birds are found worldwide.These birds are natural carriers of pathogens,because of their long-distance mi-grations across different climatic and geographic regions.The pathogens carried by migratory birds can enter ecosystems along migra-tory routes through direct and indirect contact between animal hosts,thereby potentially threatening the health of local poultry and even humans.Herein,we systematically analyzed evidence of pathogen spillover between migratory birds and poultry,and summa-rized the three modes of long-distance pathogen transmission by migratory birds(internal carriage,surface carriage,and environmen-tal contamination),as well as the two pathways of pathogen spillover between migratory birds and poultry(direct contact and indirect contact).Furthermore,this study proposes a multi-tiered mitigation strategy,grounded in the One Health framework,for targeting animal-environment-human interfaces to decrease the pathogen transmission risks associated with migratory birds.Key interventions include establishing an early-warning surveillance system for migratory flyways,enhancing biosecurity protocols in poultry production systems,and developing cross-regional risk assessment models for pathogen spread.Our findings provide critical theoretical founda-tions and empirical evidence for preventing zoonotic disease emergence and safeguarding sustainable poultry production.This inte-grated approach advances the coordinated development of biosafety measures and global health security.
