Of 6833 household members eligible for the study, 6076 (94.7% of all women and 81.0% of men) agreed to participate. HIV prevalence and incidence were 24.1% [95% confidence interval [CI] 23.0–25.2] and 1.9 new cases/100 person-years (95% CI 1.1–2.7), respectively. Among HIV-positive participants, 59.4% (95% CI 56.8–61.9) were previously diagnosed, 53.1% (95% CI 50.5–55.7) were receiving care, and 39.7% (95% CI 37.1–42.4) had viral load less than 1000 copies/ml. Applying 2013 WHO recommendations for ART initiation increased the proportion of ART-eligible people from 60.0% (based on national guidelines in place during the survey; 95% CI 57.3–62.7) to 82.0% (95% CI 79.5–84.5). Among HIV-positive people not receiving ART, viral load increased with decreasing CD4+ cell count (500–749 vs. ≥750 cells/μl, adjusted mean difference, 0.40 log10 copies/ml, 95% CI 0.20–0.60, P < 0.01).
This study demonstrates how population-level data can help optimize HIV programs. Based on these results, new regional programs are prioritizing diagnosis and expanding ART eligibility, key steps to reach undetectable viral load.
