Objective To characterise the Joint United Nations Programme on HIV/AIDS 90-90-90 cascade among female sex workers (FSW) and men who have sex with men (MSM)/transgender women (TGW) in Port Moresby, Papua New Guinea (PNG).
Methods We conducted respondent-driven sampling surveys among FSW and MSM/TGW in Port Moresby, PNG from June to October 2016. All participants spoke English or Tok Pisin and were aged >12 years. FSW had to be born female and sell/exchange sex with a male in the past 6 months. MSM/TGW had to be born male and have oral/anal sex with another male-born person in the past 6 months. Participants were interviewed and offered rapid HIV diagnostic and viral load testing. HIV viral suppression (VS) was defined as <1000 copies/mL.
Results We recruited 674 FSW and 400 MSM/TGW; HIV prevalence was 15.2% (95% CI 11.7 to 18.8) and 8.5% (95% CI 5.0 to 11.9), respectively. Among FSW living with HIV, 39.0% (95% CI 26.6 to 51.4) self-reported having been diagnosed; of them 79.6% (95% CI 62.7 to 96.5) self-reported being on antiretroviral therapy (ART), and 54.1% (95% CI 31.8 to 76.4) achieved VS. Among MSM/TGW living with HIV, 24.4% (95% CI 4.7 to 44.1) self-reported having been diagnosed; of them 43.9% (95% CI 33.6 to 54.8) self-reported being on ART, and 86.1% (95% CI 71.1 to 93.9) achieved VS.
Conclusions ART use among those aware of their HIV status is encouraging. However, the generally low awareness of infection status among FSW and MSM/TGW with HIV and the low VS among FSW on ART indicate an urgent need for innovative strategies to increase testing uptake and ART adherence among these populations. Monitoring drug resistance may be warranted.
