Genetic tuning of avian influenza A (H7N9) virus promotes viral fitness within different species

Abstract

Since their emergence in eastern China, novel influenza A (H7N9) viruses have been continuously circulating in poultry and causing human infections and death. We have proposed a "genetic tuning" mechanism for the genesis and evolution of the novel H7N9 virus during interspecies transmission.

Keywords: Avian influenza A (H7N9) virus; Genetic tuning; Potential hosts.
