We reconstructed the recent transmission history of #YellowFeverVirus in #Brazil. A suitability index was able to capture the seasonality of #zoonotic cases. Spatial modeling revealed hotspots with both past reporting and low #vaccination coverage, coinciding with the largest urban centers in the Southeast. #Phylodynamics identified 3 lineages & provided proof of the directionality of a spatial corridor connecting the endemic North with the extra-Amazonian basin.
