摘要：Summary. We estimated the prevalence of HIV, HBV and HCV infections among injecting and noninjecting
drug users treated within public drug-treatment centres in Italy to determine the correlates of
infection. In the sample of 1330 drug users, the prevalence of HIV was 14.4% among drug injectors and
1.6% among non-injectors; the prevalence of HBV was 70.4% among injecting drug users and 22.8%
among non-injectors and of HCV was 83.2% among injecting drug users and 22.0% among non-injectors.
Old age, unemployment, and intravenous drug use were significantly correlated with each of the
infections, as well as a longer history of injecting drug use. The results indicate that these infections
continue to circulate among drug users, highlighting the need for monitoring of this group in Italy.
