Phylogenetic tree based on the nucleotide protein (N) gene sequences of various strains of the measles virus. The evolutionary distance was calculated using Kimura's two-parameter method, and the tree was plotted using the neighbor-joining method. Numbers at each branch indicate the bootstrap values of the clusters supported by that branch, only more than 75% of bootstrap value is indicated. Jiangsu cases were circled with rectangle line.

The further phylogenetic analysis showed the measles viruses in this event belong to D8 genotype (Fig. 1, Fig. 2).
