The seroprevalence of antibodies to HEV was determined in three different Italian populations (volunteer blood donors, normal healthy individuals, and intravenous drug users [IVDUs]). The seroprevalence in the populations ranged from 0.74% to 1.94%, with higher rates among IVDUs and individuals over 40 years of age. None of 35 patients diagnosed with acute hepatitis A but 10 of 153 (6.5%) patients with acute nonA, nonB, nonC hepatitis were found to be positive for anti-HEV antibody. One of these antibody positive cases was linked to travel, while the remaining 9 were not associated with travel to endemic areas. These data suggest a possible low circulation of HEV in Italy.

Abstract
The seroprevalence of antibodies to HEV was determined in three different Italian populations (volunteer blood donors, normal healthy individuals, and intravenous drug users [IVDUs]). The seroprevalence in the populations ranged from 0.74% to 1.94%, with higher rates among IVDUs and individuals over 40 years of age. None of 35 patients diagnosed with acute hepatitis A but 10 of 153 (6.5%) patients with acute nonA, nonB, nonC hepatitis were found to be positive for anti-HEV antibody. One of these antibody positive cases was linked to travel, while the remaining 9 were not associated with travel to endemic areas. These data suggest a possible low circulation of HEV in Italy.
