Figure 1

Detail of highly pathogenic avian influenza A(H7N9) viruses isolated from human and environmental sources, Shaanxi Province, China, 2016–2017, showing Shimodaira-Hasegawa-like local bootstrap support values. Amino acid changes within the hemagglutinin cleavage site are indicated on basal branches. The low pathogenecity strain A/Environment/Guangdong/15120/2016 is used as an outgroup. An expanded version of this figure showing comparisons to reference viruses is available in Technical Appendix Fi
