Background: The authors report on the prevalence of, and risk factors for, hepatitis A virus (HAV) in a group of drug users in Italy. Methods: 404 heroin users were recruited and compared with a control group of 107 subjects in the general population. Results: Drug users born in north-eastern Italy have a prevalence of anti-HAV similar to the control group. A much higher prevalence was found in drug users born in southern Italy. Conclusion: The similar prevalence of anti-HAV in drug users born in north-eastern Italy and in the general population, suggests that their lifestyle does not involve a substantial additional risk of HAV. The much higher prevalence found in drug users born in southern Italy is more likely to be related to infection during infancy.
