FIG. 1.

Phylogram of flaviviruses using a neighbor-joining inference method (MEGA) based on the complete RNA-dependent RNA polymerase domain of the NS5 gene of 35 viruses deposited in GenBank. The numbers at nodes indicate % branch supports by bootstrap sampling with 500 replicates. Distances were calculated with Poisson correction.
