Int J Infect Dis 2022 116 245-254 OBJECTIVES: The 2018-19 Rwanda Population-based HIV Impact Assessment (RPHIA) was conducted to measure national HIV incidence and prevalence. District-level estimates were modeled to inform resources allocation. METHODS: RPHIA was a nationally representative cross-sectional household survey. Consenting adults were interviewed and tested for HIV using the national diagnostic algorithm followed by laboratory-based confirmation of HIV status, and testing for viral load (VL), limiting antigen (LAg) avidity and presence of antiretrovirals. Incidence was calculated using normalized optical density ≤ 1•5, VL ≥ 1,000 copies/mL, and undetectable antiretrovirals. Survey and programmatic data were used to model district-level HIV incidence and prevalence. RESULTS: Of 31,028 eligible adults, 98•7% participated in RPHIA and 934 tested HIV positive. HIV prevalence among adults in Rwanda was 3•0% (95% CI:2•7-3•3). National HIV incidence was 0•08% (95% CI:0•02-0•14) and 0•11% (95% CI:0•00-0•26) in the City of Kigali (CoK). Based on district-level modeling, HIV incidence was greatest in the three CoK districts (0•11% to 0•15%) and varied across other districts (0•03% to 0•10%). CONCLUSIONS: HIV prevalence among adults in Rwanda is 3.0%; HIV incidence is low at 0.08%. District-level modeling has identified disproportionately affected urban hotspots: areas to focus resources. |
