Tracking the return of Aedes aegypti to Brazil, the major vector of the dengue, chikungunya and Zika viruses

In this study we revisit the analysis of Ae. aegypti genetic diversity in Brazil by screening for genetic diversity at 12 microsatellite loci in 48 Brazilian and non-Brazilian populations, a much denser spatial sampling than in previous studies. We use these data to study the patterns of genetic differentiation among populations of Ae. aegypti in Brazil at a fine geographic scale, to describe their genetic affinities with populations from neighboring regions from both South and North/Central America and the Caribbean, and to reconstruct the history of the re-appearance of Ae. aegypti in Brazil.
