Phylogenetic tree of DENV-3. The phylogenetic tree is based on the complete E gene sequences of nine strains of DENV-3 including two imported cases, and constructed by using the neighbor-joining method with bootstrap 1000 replications. The sequences were named according to strain/country/year/serotype of collected viruses. GenBank accession numbers of the reference sequences are shown in the parentheses. GenBank accession No. of imported strains were listed in Table 2. The imported cases are designated in solid triangle
