      Between March 21 and July 3 2000, a serum sample and a questionnaire on risk behaviour were obtained from 217 IDU in Den Haag. Participation was on a voluntary basis. Participants were recruited at methadone treatment sites (35%) and low-threshold daytime care projects (65%). Of 211 IDU, four persons were found to be infected with HIV (prevalence 1.9%, 95% confidence interval [CI] 0.5 - 4.8). Thirtyfive percent of the participants had antibodies to HBc (previous or current HBV-infection), for 3% of the participants HBsAg was detected in the blood (carrier). Of the IDU, 47% had antibodies to HCV. The prevalence of anti-HBc and -HCV is lower than in other cities in the Netherlands. Sixteen (20%) out of 81 currently injecting IDU borrowed syringes or needles in the last 6 months, this level is somewhat higher than in other cities studied in the Netherlands. Twenty percent lent syringes or needles to other IDU. Condom use was very low during sexual contact between steady partners (84% not always using a condom). 48% of the IDU have a non-drug user as a steady sexual partner. With casual partners and clients, condoms were used more often. The risk of further spread of HIV among IDU in Den Haag is low. At this low level of HIV prevalence, the risk of spread to non-IDU or the general population is also low.
