Abstract:

Hemagglutinin(HA) and Neuraminidase(NA) of influenza viruses are easy to have antigenic drift and antigenic shift, and new pathogenic subtype which is able to infect humans can be formed by such viral mutations.Genetic reassembly which always happens in H5N1 subtype accelerates the threat of avian influenza Aviruses to human being.In addition, bird migration contributes to the global spread of emerging infectious disease.Therefore, we review current knowledge regarding the harm, pathological properties, pathogenicity of avian influenza viruses and discuss the influence of bird migration to the global spread of the viruses.
