Main Article

Figure

Maximum-likelihood phylogenetic tree for dengue virus serotype 3, lineage III_B.3.2, Angola. Tips are colored by country of infection. Luanda sequences are shown in red (Appendix Figures 5, 6, https://wwwnc.cdc.gov/EID/article/31/11/25-1079-App1.pdf). Countries with <10 sequences are grouped as other and include Costa Rica (n = 7), Trinidad and Tobago (n = 7), Haiti (n = 4), Guyana (n = 3), Italy (n = 2), El Salvador (n = 2), Saint Lucia (n = 1), Saint Martin (n = 1), Panama (n = 1), Niger (n = 1), and Venezuela (n = 1).
