The new H7N9 influenza virus, recently emerged in China, can replicate in human airway cells and in the respiratory tract of ferrets to a higher level than can seasonal H3N2 virus and shows higher lethality in mice than genetically related H7N9 and H9N2 viruses, but shows limited transmission in ferrets by respiratory droplets.
