Fig. 5: Maximum likelihood tree for CHIKV based on complete genome sequences from SJdRP, other cities within the RHD-XV and all Brazilian regions.
From: Vector surveillance during a major chikungunya outbreak in northwestern São Paulo state, Brazil
Time-stamped phylogenetic tree reconstructed using 526 Brazilian complete genomes of ECSA genotype (141 from this study) from all Brazilian regions (Supplementary Table 10), highlighting the clade formed by CHIKV sequences obtained from Aedes, Culex and human samples generated in this study, which are grouped with sequences from Minas Gerais, São Paulo, Paraná and Tocantins states. Linear regression of root-to-tip genetic distance of CHIKV versus sampling date. Colors represent different Brazilian regions or locations. The bar next to the phylogeny represents different hosts. Genome sequences from mosquitoes and human samples obtained in this study are highlighted with black borders.
