  1. MAPPING TRANSACTIONAL SEX ON THE TRANS-AFRICA HIGHWAY Alan Ferguson1 Chester Morris2 1 Constella-Futures and University of Manitoba 2 University of Manitoba

  2. Vulnerable people and vulnerable places • Even in generalized epidemics, vulnerable groups disproportionately affected • Where epidemic has peaked, re-concentration of infection in vulnerable groups • Increasing evidence of locations that make people vulnerable to HIV

  3. OBJECTIVES • Measure volume and characteristics of highway-based transactional sex on section of Trans-Africa highway • Identification of ’Hot Spots’ • Risk-avoidance practices and un-met needs • Client characteristics • Use of GIS in visualization and planning

  4. 1. GIS METHODS GPS mapping of stopovers between Mombasa and Kampala Mapping of aggregate data at national / regional level

  5. METHODS 2. Sex Worker Diaries (n=578) • Completed for 28 consecutive days • Permit calculation of: • No. partners, liaisons, sexual acts • Condom use • Occupation of client • Sex during menses • Mobility

  6. METHODS • Truckers FGDs (6) • Truckers surveys (4) • Sex Worker FGDs (22) • Truck Census (all stopovers) • Bar census / survey (1,007)

  7. Basic results

  8. Stopover points

  9. Mean nos. overnight trucks

  10. Mean no. trucks / FSW estimates

  11. Truck and sex worker volumes: Uganda sector

  12. Example of thematic map of single hot spot

  13. Mean levels of transactional sex

  14. Variations in mean monthly # sexual acts

  15. Transactional sex by type of partner

  16. Condom use per liaison by type of client

  17. Client occupations

  18. HIV Transmission • Using AVERT model, estimated that 3,200 – 4,200 new infections per annum from transactional sex on highway • Raising condom use to 90% would avert almost 2/3 of these new infections

  19. CONCLUSIONS • High levels of highway-based transactional sex in E. Africa • Despite high levels of condom use, HIV transmission significant • Client base much wider than expected suggesting a ‘vulnerable places’ approach to programming • Both FSWs and truckers socially marginalized

  20. CONCLUSIONS - Methodology • GIS proved to be effective in visualization and advocacy • Diaries are flexible and efficient means of generating data where recall and social desirability biases are present
