      In this study the spread of HIV among intravenous drug users (IDU) in Utrecht, the Netherlands, and the risk of further spread among IDU, to non-IDU and to the general population is assessed. Between 11 March and 19 April 1996 a saliva specimen and a short questionnaire on risk behaviour were obtained from 196 IDU in Utrecht. Participants were recruited through methadone care (53%), a daytime care project (41%) and a street prostitution project (5%). Of the 196 IDU, 10 were infected (prevalence 5%, 95% confidence interval [CI] 2.4-9.4%). Needle and syringe exchange programmes had a high coverage among currently injecting IDU (84%). IDU not participating in needle exchange programmes were infected more often: 3/19 as compared 3/99. 17% of the currently injecting IDU reported borrowing a used syringe or needle in the last six months. 18% of the IDU have a non-drug user as steady sexual partner. Condom use was low during sexual contact between steady partners. In conclusion, the prevalence of HIV among IDU in Utrecht was about 5%. The needle and syringe exchange programmes have good coverage, but a higher coverage could probably prevent more infections. Injecting risk behaviour occurs regularly. Spread to non-IDU or to the general population is possible on a limited scale.<br>
