Individuals centre for anonymous testing randomly included study. All samples tested HBV surface antigen (HBsAg), anti-HCV anti-HIV-1 2 Results. A total 431 (262 169 men) studied, whom 10.0% (43/431) seropositive 4.6% active syphilis; 8.8% (38/431) and/or HIV-2 (of these, 78.9% HIV-1-positive, 2.6% HIV-2-positive 18.4% co-infected); 9.3% (40/431) HBsAg-positive, while (35/431) HCV.

Three viral co-infection, 1 case 2. Five (1.2% total) three 3 cases Conclusions. high studied found population, including infection (8.8%). These results demonstrate need improve screening treatment other educational campaigns prevent not only morbidity mortality associated diseases, but also their further transmission.
