Figure A1. The maximum-likelihood phylogenetic tree for chikungunya envelope glyprotein 1 (E1) sequences (199 bp) constructed by using PAUP* under a Tamura-Nei 1993 model with invariable sites (i.e., TrN+I), as selected by MODELTEST (version 3.7) under the Akaike information criteria. The bracket shows that the PWH patient E1 sequence (DQ489787) clusters most closely with the outbreak La Reunion sequence (LR2006_OPY1_Reunion_2006_E1, DQ443544). Only bootstrap values >70 are shown and considered significant. The tree is rooted against the earliest sequence (AF490259/Ross_Tanzania_1953).
