Forty-one of the 137 examined pigs (29.9%) tested positive for HEV RNA. Animals of 80–120 days of age showed a higher prevalence of HEV infection (46.9% against 20% of younger animals). No statistically significant correlations between HEV positivity and the presence of other pathological conditions detected at necropsy, or concomitant coinfections with PCV2 and/or PRRSV were detected. All identified strains belonged to genotype 3, and were similar to other HEV subtypes 3e, 3f, 3c circulating in Europe.
