RESUMO
The prevalence of HIV infection among intravenous drug addicts (IVDAs) was 11% in Belgrade in 1997 (500 IVDAs). There are only two ways of transmission of HIV infection among IVDAs: the use of contaminated needles and syringes and sexual intercourse with an infected partner. We established in the counselling office for IVDAs that only 47.8% of them were injected with their own devices, 43% shared somebody's equipment, and 9.2% used other routes for drug taking. Condoms or safe sex were exceptional. Only 10.17% used condoms regularly; 12.5% from time to time and 77.32% never. Among 391 interviewed IVDAs 7% were not sexually active during the last year, 40% had one constant partner, 32% had intercourses with 2 to five partners, and 21% were promiscuous (more than 5 partners over one year). Fifty five were seropositive against HIV. Ten of them were promiscuous and used no condom. There is some evidence that the majority of IVDAs after twelve years of post seroconversion (average age between 35 and 45), stopped their sexual activity. The prostitution of female IVDAs in order to finance their own and their partners supply of drugs is found in 3% of cases. This study can be helpful in implementing a selective and individual approach to some IVDAs with risk behaviour, who accept treatment, to prevent the spreading of infection.
