![Phylogenetic analysis of whole genome nucleotide sequences of chikungunya virus (CHIKV) isolated during the 2013 outbreak in Bueng Kan Province, Thailand. The trees were generated by maximum-likelihood method, and the numbers along the branches indicate bootstrap values. Scale bar denotes nucleotide substitutions per site. Branch support and nodal confidence was assessed by using a general time reversible +I−4 nt substitution model with 1,000 bootstrap resampling. All sequences are labeled with](/eid/images/14-0481-F1.jpg)
