Phylogenetic tree showing relatedness of HIV-1 <i>pol</i> sequences from MSM volunteers with acute and early infection from Coastal Kenya, 2005–2017 (N = 97) with reference sequences from the Los Alamos database (N = 158).

Tip labels colored according to risk group as follows: grey (references), blue (men who have sex with men exclusively, MSME) and green (men who have sex with men and women, MSMW). Branches are colored according to HIV-1 pol subtype inferences as follows: grey (subtype references), red (subtype A1), purple (subtype D), brown (subtype C) and green (subtype G). Table showing a summary of HIV-1 pol subtype inferences by MSME and MSMW.
