Figure 1.

Maximum clade credibility tree of DENV-1. The genotypes I to V are identified by colorful internal blocks. Genotype V, which includes most of the reference sequences and all Brazilian DENV-1, is also classified into lineages and sub-lineages. Small black dots denote the most important nodes with posterior probability >0.7. The tree is scaled by years, represented by vertical line denoting the present (time zero) to 150 years before the present. Sequences from Araraquara were colored according to the year of sampling, 2015–2022 (colorful circles).
