Abstract:Wild birds were reported as natural reservoir of avian influenza viruses (AVI) which are highly variable. We analyze the risk of AVI in China from considering the geographical, ecological and traditional farming situation especially in southern China, and suggest to conduct the AVI-wild bird survey and monitoring action plan so as to find the wild hosts and resource of AVI in order to effectively prevent the AIV primary infection and spread from wild bird to poultry and AI outbreak and dissemination to other areas.
