  1. High incidence of HIV in young women despite high ART coverage and viral load suppressionResults from a population-based survey in KwaZulu-Natal, South Africa Helena Huerga MSF-OCB Operational Research Day 2014

  2. Background • South Africa highest number of people with HIV and on ART in the world • MSF working in South Africa since >10 years • Kwazulu-Natal (KZN): project “Bending the Curves” • Aim to reduce HIV/TB incidence and morbi-mortality • Gradually implemented since 2011

  3. Background Good understanding of HIV epidemic in a community essential to define strategies of intervention HIV+ at health facilities (partial view of community) HIV surveys in population (overall view of community)

  4. Objectives Primary: Toassess ART coverage Secondary: • To estimate HIV incidence & prevalence • To assess viral load suppression • To assess HIV testing coverage and access to HIV care & ART • To assess access to PMTCT and male circumcision coverage

  5. Methods • Design: cross-sectional study • Population: • Aged 15-59 years • Living in Mbongolwane / Eshowe • Survey area: • Pop: 115,000 hab. • Rural, urban and farms • 2 hospitals & 10 ART clinics • MSF project: • HIV testing in community • Linkage to care • Support to MOH on ART • Early ART <500CD4 • PMTCT B+ • Male circumcision

  6. StudyProcedures

  7. Results: who participated? 2377 HH visited –> 6688 individual eligible –> 5649 (84.5%) included Table: Participants’ socio-demographic characteristics

  8. HIV prevalence: How many were HIV-positive? • Overall: 25.2% (95%CI: 23.6-26.9) • Women age 30-39: 56% • Women: 30.9% (95%CI: 29.0-32.9) • Men: 15.9% (95%CI: 14.0-18.0)

  9. HIV incidence: How many new infections per year? PY: person-year

  10. ART coverage: How many in need of treatment were on ART? • Overall: 75.0% (95%CI: 72.0-77.8) • Women age 20-24: 42% • Women: 78.5% (95%CI: 75.8-81.0) • Men: 63.9% (95%CI: 56.7-70.5) • 89% successfully treated with ART (VL<1000 copies/ml)

  11. When did they start ART? • Time since ART initiated: 31.0 m (IQR: 12.4-61.0) • Year range ART initiated: 1992-2013 Start MSF project

  12. HIV testing: who tested where? • HIV testing: 81.4% (95%CI: 79.8-82.9) • Women: 88.4% (95%CI: 86.8-89.9) • Men: 69.8% (95%CI: 67.2-72.4) • Time since test: 6 months (IQR: 3-16) • Number of tests: 3 times (IQR: 2-4) Public sector

  13. Who was already aware of their HIV infection? • Awareness: 75.2%(95%CI:72.9-77.4) • Women & men 20 -24 y: 43.1% & 83.3% • Women: 77.7% (95%CI: 75.1-80.1) • Men: 67.3% (95%CI: 62.0-72.1)

  14. Cascade of care Of all HIV positive, 49% had no detectable virus, and hence were not transmitting HIV.

  15. Discussion • KZN survey: • ART coverage and VL suppression relatively good • Overall moderate incidence in a high HIV prevalence area • High incidence in young women • Impact on the HIV epidemic but gaps in cascade of care • Limitations: cross-sectional design in mobile population • Strengths: survey in population, inclusion rate

  16. Discussion • Recommendations: • Maintain quality and go further to enlarge eligibility criteria • Develop strategies to test, link and treat young people 20-30y • Include interventions for prevention focused on young women • Implications on the operations: • HIV population based surveys are critical to define strategies • Change orientation of MSF intervention in KZNafter survey?
