Hepatitis B and C viruses and sexually transmitted disease patients in Jamaica

Objectives: To determine the prevalence of hepatitis C virus (HCV), hepatit is B virus (HBV), human immunodeficiency virus (HIV) infections, and risk f actors for HCV and HBV infections in sexually transmitted disease (STD) cli nics in Jamaica. Methods: A prospective observational cohort study was carried out. Blood wa s collected from 485 consecutive patients attending the comprehensive healt h centre in Kingston, Jamaica. Serum was tested using commercially prepared reagents and standard procedures for antibodies to HCV (anti-HCV), hepatit is B core antigen (anti-HBc), hepatitis B surface antigen (HBsAg), HIV-1 in fection, and syphilitic infection. Sociodemographic and sexual characterist ics of the patients were recorded for assessment as risk factors for HCV an d HBV infections. Results: None of the patients had anti-HCV, 21.0% had anti-HBc, 3.2% HBsAg, 2.5% tested positive for HIV-1, and 5.2% had reactive serological test for syphilis. Age was the only independent risk factor identified for anti-HBc positivity. Conclusions: The data obtained in this study were not in support of sexual transmission of HCV or HBV infections in Jamaica. Carefully designed multic entre studies could provide more consistent information on the transmission of these viruses by sexual routes.
