Codon positions predicted to be under episodic positive selection, showing the amino acid changes and the proteins altered.

Amino acid position is defined using the Genome sequence 3908 (Accession number U55350 in the NCBI database) and numbered against the non-structural and structural polyproteins.氨基酸位点的定义依托基因组序列3908（NCBI数据库登录号为U55350），并以非结构多聚蛋白与结构多聚蛋白为参照进行编号。
