A longitudinal study on the incidence and transmission patterns of HIV, HBV and HCV infection among drug users in Amsterdam.
In the present study data on the incidence of HBV and HCV were used to indicate the prevalence of and trends in risk behavior, assuming that drug users (DUs) who become infected with HBV or HCV are also at risk for infection with HN.
In addition, we determined to that extent the transmission patterns of HIV, HBV and HCV differed.
DUs were selected from a cohort study in Amsterdam, had at least one follow-up visit between December 1985 and September 1989 and reported never to have had homosexual contacts.
Among 305 DUs, of whom 70% injected recently, the prevalence of HIV, HBV and HCV were 31%, 68% and 65% respectively.
These prevalences were strongly interrelated and the same risk factors were found.
The cumulative incidence of either HIV or HBV or HCV was 30% among prevalent HN-negatives.
