We determined the pathogenicity of more than 30 H5N1 HPAI viruses in Pekin ducks and conducted full viral genome sequencing to determine virulence markers associated with disease and mortality. We found that virulence of H5N1 HPAI viruses in ducks appears to be multigenic and cannot be attributed to one specific genetic change.
