Despite the growing importance of hepatitis E virus (HEV) in industrialized countries, minimal attention has been given to autochthonous HEV infection in children. The present study screened archived sera (N=71) from a Portuguese pediatric cohort collected in 1992-1995 for the presence of antibodies against HEV, using enzyme immunoassays and immunodot. Anti-HEV IgG was detected in two children and anti-HEV IgM in one, suggesting an acute HEV infection. This shows that HEV was circulating in the paediatric population of Portugal in the early 1990s.
