*Gray shading indicates infections with STLV-1–like HTLV-1 (as determined through phylogenetic analyses). Minimum distances were calculated by using the same datasets as for phylogenetic analyses (see Technical Appendix). HTLV-1, human T-lymphotropic virus type1; STLV-1, simian T-lymphotropic virus type1; LTR, long terminal repeat; chimp, chimpanzee(s).
†First 3 letters refer to the persons’ village of residence.
