Schematic representation of the relationship between MAYV spread and human population connectivity and migration patterns among central South American and Haiti following the 2010 Haiti earthquake. (A) Time-scaled phylogenetic DensiTree representation of the Markov chain Monte Carlo sampled trees from the Bayesian posterior distribution. Branches are colored according to geographical location (legend at right). Well-supported branches are indicated by regions of high density (more solid color), whereas low-density regions (webs) indicate little agreement amongst the trees. (B) MAYV migration patterns inferred from Bayesian phylogeographic analysis using a discrete trait asymmetric diffusion model represented using SPREAD. Letters in bold indicate the major genotype circulating in each shaded area. (C) MAYV migration patterns superimposed onto the accessibility map of the Amazonian basin, and (D) compared to human migration started in 2010 from Haiti to Brazil and Peru, indicated by dotted green lines with directionality. Brazilian contribution to MINUSTAH personnel in Haiti during 2010–2015 is represented by green bubbles, with the size of each individual bubble corresponding to the number of uniformed personnel present during each year. MAYV migration patterns represented in (B,C and D) represent significant non-zero migration rates (Bayes Factor [BF] > 10), and are colored according to BF (legend at right). Maps were obtained from Google Maps (https://mapstyle.withgoogle.com), SPREAD software (www.kuleuven.be/aidslab/phylogeography/SPREAD.html), and ArcGIS database (https://www.arcgis.com) based on a previously published and available dataset (https://tiles.arcgis.com/tiles/P8Cok4qAP1sTVE59/arcgis/rest/services/Accessibility_Travel_time_to_Major_Cities/MapServer).
