Phylogenetic analysis of HIV sequences obtained in a respondent-driven sampling study of men who have sex with men.
The presence of transmission clusters and their relationship to the recruitment chain were investigated in an HIV prevalence assessment survey using respondent-driven sampling among men who had sex with men (MSM) in Zagreb, Croatia. HIV infection was found in 18 of 360 participants. Five individuals belong to a transmission cluster of MSM infected with phylogenetically related HIV. All were recruited in later waves (fourth to ninth), suggesting that the population is sexually networked.
