During a 6-year observational study, 122 cases of hepatitis A virus (HAV) infection were detected in Bologna, Italy, with a c. 300% increase in cases between 1999 and 2004. There were 104 cases (85.2%) in male adults, of whom nearly 70% had unprotected sexual contact as the probable risk-factor. There were increasing numbers of cases in immigrants between 1999 and 2004 (p 0.036), and concurrent cases of infection with human immunodeficiency virus, hepatitis B and C viruses and syphilis were also noted in adult males (p 0.0032). There is a need to re-emphasise targeted educational programmes and anti-HAV vaccination for at-risk subjects.
