DENV-1 re-emergence in Brazil. (A): Brazil's five geographical regions: North, Northeast, Midwest, Southeast and South. In gray, Rio de Janeiro's localization. (B): Dengue viruses (DENV) serotypes replacements and DENV-1 emergence in Brazil, by region from 2007 to 2010. (C): Neighbor-joining phylogenetic of ten complete envelope (E) gene sequences from DENV-1 isolated during two periods epidemiologically distinct: 1986 (n = 2) when the serotype was first introduced and after its emergence in 2009-2011 (n = 8). The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. Black circles represent DENV-1 sequences generated in this study. DENV strains used were named as follows: GenBank accession number/country/year.
