Fig 1.
Phylogenetic analysis of HIV-1 strains identified from MSM in Taiwan in 2012.
Neighbor-Joining tree based on env (7077–7619 nucleotide residues of HXB2) nucleotide sequences. All branch lengths are drawn to scale. Red circle indicates MSM patients from a gay bar. Aqua circle indicates MSM patients from gay night clubs. Blue circle indicates MSM patients from gay saunas. Green triangle indicates local controls from Taiwan. Clusters with bootstrap value ≥ 70 were labeled from numbers 1 to number 9.

Analyses of the characteristics of the clusters of the phylogenetic trees based on age or illegal drug use.
(A) Characteristics of the cluster based on age. Green circle indicates 15–24 years old. Blue circle indicates 25–34 years old. Brown circle indicates 35–44 years old. Red circle indicates data not available (NA). (B) Characteristics of the cluster based on illegal drug use. Yellow circle indicates illegal drug use. Purple circle indicates no illegal drug use. Red circle indicates data not available (NA). Clusters with bootstrap value ≥ 70 were labeled from numbers 1 to number 9 and number of individuals per cluster recruited in this study.
