From: Chikungunya virus infection in Indonesia: a systematic review and evolutionary analysis
Phylogenetic tree of 127 Indonesian Chikungunya viruses and 1589 reference sequences from GenBank. The phylogenetic tree was generated using the maximum likelihood (ML) method available in the Randomized Axelerated Maximum Likelihood (RAxML) program with General Time Reversible and gamma substitution model (GTR + Γ). The tree shows the position of ten viruses of East/Central/South African (ECSA) genotype and 120 of Asian genotype from Indonesia relative to other viruses isolated worldwide
