    Science Forum: Viral factors in influenza pandemic risk assessment

    Marc Lipsitch et al.
    We identify key strengths and limitations in use of viral genotyping and phenotyping to estimate pandemic risk from influenza A viruses, focusing on 3 traits, hemagglutinin binding specificity, hemagglutinin pH of activation, and polymerase complex efficiency.
