Strong propensity for HIV transmission among men who have sex with men in Vietnam: behavioural data and sexual network modelling

摘要

ObjectivesSurvey data from men who have sex with men (MSM) in Asian cities indicate ongoing and drastic increases in HIV prevalence. It is unknown which behavioural factors are most important in driving these epidemics. We aimed to analyse detailed sexual behaviour data among MSM in Vietnam and to model HIV transmission using improved assumptions on sexual network structure.
