Geographic distribution of Aedes-borne arbovirus genome sequences sampled for phylogeographic analyses.

(A) Geographic distribution of DENV-1, DENV-2 and CHIKV virus genomes from the region of the Americas included for phylogeographic analyses in this study. Maps are coloured according to the number of sequences sampled per country. (B) Geographic distribution of DENV-1, DENV-2 and CHIKV virus genomes from Mexico included in this study. The map on left indicates the 32 states from the country, whilst the map of the right shows in different colours the distinct geographic regions (comprising different states) from which Aedes-borne virus genomes are available from. Plots were generated using the ggplot package (https://ggplot2.tidyverse.org/index.html) in R. Original base layer maps use as a source for geospatial base layer data public domain maps imported from the Natural Earth data project (https://cran.r-project.org/web/packages/rnaturalearth/index.html).
