Social and Genetic Networks of HIV-1 Transmission in New York City
Fig 6
Genetic distance (TN93) separating index cases and named partners in select risk groups.
(A) Genetic distance between named heterosexual partners. (B) Genetic distance between named MSM partners. (C) Genetic distance between named partners where at least one partner reported injection drug use (IDU). (D) Genetic distance between named partners where at least one partner was diagnosed with acute or early HIV infection. Additional tick marks on the x-axis indicate epidemiologically plausible thresholds between 0.01 and 0.02 substitutions/site are shown on x-axis. Blue denotes potential transmission partners (≤0.02 substitutions/site). Red denotes partners with “random” within or between subtype viral divergence.
