INFECTIONS
We identified a total of 300 likely transmission pairs. 178 (59·4%) were male to female, with 130 (95% CI 110–150; 43·3%) from males aged 25–40 years. Overall, men transmitted 2·09-fold (2·06–2·29) more infections per capita than women, a ratio peaking at 5·87 (2·78–15·8) in the 35–39 years source age group. 40 (26–57; 13·2%) transmissions linked individuals from different communities in the trial. Of 288 sources with recorded information on drug resistance mutations, 52 (38–69; 18·1%) carried viruses resistant to first-line ART.
