A) Polymerase basic 2; B) polymerase basic 1; C) polymerase acidic; D) nucleoprotein; E) matrix; F) nonstructural. Avian H9N2 viruses are shown in green, avian H9N2 viruses from Guangdong Province in blue, human H7N9 sequences from Guangdong Province in pink, and human H7N9 sequences from the main case cluster in 2013 in eastern China in red. Blue boxes indicate clusters of patient sequences on separate branches; numbers correspond with the reassortant numbers listed in Table 2, where 0 indicates original genes from the 2013 cluster of influenza A(H7N9). Individual trees are shown in the Technical Appendix.
