Abstract
A cross-sectional study of 400 patients attending sexually transmitted disease (STD) clinics at The Venereal Diseases and AIDS Centers, Regional 2, Thailand, was conducted from January to December 1996 in order to investigate the antibody prevalence to human immunodeficiency virus (HIV) and hepatitis C virus (HCV) and to describe some epidemiological characteristics among HIV and HCV co-infected individuals. The studied patients were interviewed and their blood specimens were collected for determining anti-HIV and anti-HCV antibodies. The results revealed that the prevalence of anti-HIV among studied patients was 25%, while 7.5% were positive for anti-HCV The positivity of both antibodies present in the same individuals was 3.3% (13/400 cases). The highest prevalences of anti-HIV, anti-HCV and both antibodies were found in studied patients aged 20 years or less. Patients with primary education, or lower, had relatively higher prevalence of anti-HIV and/ or anti-HCV than those with higher level education. A relatively higher prevalence was found among commercial sex workers and labourers. Among 13 HIV and HCV co-infected individuals, there were four cases who had histories of sexual contact without condom use, but no history of parenteral contact. The rest (9/13) had histories of both parenteral contact and sexual contact without condom use. Asia Pac J Public Health 2000;12(1):41-45
