The sequences of Zhejiang strains isolated in 1982–1983 and 2007–2014 in this study are marked in black rhombus and circle, respectively. Phylogenetic analysis was performed by the neighbor-joining method using the MEGA 6.2 software package (www.megasoftware.net). Bootstrap probabilities of each node were calculated using 1000 replicates. Murray Valley encephalitis virus strain MVEV-51 was used as an outgroup. Scale bars indicate the number of nucleotide substitutions per site.
