Prevalence of HTLV-I Infection and Its Association with Tuberculosis among Patients at an Urban Clinic in Haiti.

This retrospective case-control study examined the prevalence of HTLV-I and its association with tuberculosis among urban clinic patients in Haiti. Prevalence of HTLV-I among tuberculosis cases was 2.1% and among controls was 2.4%. Prevalence of HLTV-I was higher in females than males (odds ratio [OR] 2.45, P = 0.020). HTLV-I prevalence in those ≥ 50 years was 8.4% compared with 1.3% in those < 50 (OR 6.74, P < 0.001). We found no association between HTLV-I and tuberculosis in this population.
