Abstract
Background: The prevalence and incidence of syphilis infection were examined in a cohort study of factory workers in Ethiopia.
Method: Between February 1997 and March 1999, 409 men and 348 women were enrolled and followed in the cohort study.
Results: The prevalence (95% CI) of past/current syphilis (positive TPPA serology) was 28.9% (25.7% to 32.3%), and factors associated with past/current syphilis were markers of risky sexual behaviours including HIV infection. In this cohort of factory workers subject to public information/education meetings, testing for HIV antibodies, and individual counselling, the incidence (97.5% one sided CI) of new syphilis infections was 0/691 = 0 (0 to 0.5) per 100 person years.
Conclusion: This study has documented a reduction in risky sexual behaviours and a low syphilis incidence among factory workers participating in a cohort study on HIV infection progression in Addis Ababa
