Abstract：West Nile Fever(WNF),an arthropod-borne illness caused by West Nile Virus(WNV),is maintained in nature through a transmission cycle involving birds as reservoirs hosts and mosquitoes as primary vectors.This study,based on the WNV infection surveillance data noticed by World Organization for Animal Health(WOAH)during 2005-2024,using the WOAH risk analysis framework—specifically,an"Introduction Assessment—Exposure Assessment—Consequence Assessment"model,systematically carries out an import risk analysis of WNF by examining the pathogenic characteristics,cross-border transmission mechanisms and global epidemiological features of West Nile virus.The results showed that mosquito-borne transmission,migratory bird routes and animal trade were the main risk factors for the importation of WNF into China,and the import risk of WNF has remained at a medium-high level for a long time.It also proposes a risk management strategy that combines standards,quarantine and supervision.To mitigate the import risk of WNF,a risk management strategy integrating regulatory measures,strengthened quarantine,intelligent surveillance,and technological advancements.This study aims to provide a scientific foundation for China's transboundary zoonosis prevention and control efforts,safeguarding both public health security and livestock production stability.
