Figure 4

Phylogenetic analysis of the hemagglutinin gene of highly pathogenic avian influenza A(H7N9)  viruses in Guangdong Province, China, and reference viruses. Maximum likelihood trees were constructed with PhyML by using the general time reversible plus gamma distribution plus proportion of invariable sites model. Node support was estimated by the SH-like aLRT method, and values >0.8 are shown. Virus clades A, B, and C—previously defined as W2-A, W2-B, and W2-C (5)—are labeled. A/Guangdong/17SF00
