Seroprevalence of Hepatitis E Virus Infection in Children in the Southwest of Iran

Aims: hepatitis e virus (hev) infection causes an acute, self-limiting hepatitis that is associated withhigh mortality, especially in pregnant women. our previous clinical experiences indicated that there was a high prevalenceof hepatitis a virus (hav) among school-age children in the city of ahvaz (in the southwest of iran). due to thefact that hev is transmitted generally by the same route as hav, the present study was performed to determine theseroprevalence of hev among school-age children in ahvaz.methods: in a cross-sectional study, the seroprevalence of anti-hev antibodies was determined in sera from 566 childrenaged 6–15 years by enzyme-linked immunosorbent assay (elisa). the study population included 257 (45.4%) males and309 (54.6%) females.results: anti-hev antibodies were detected in 48 children (8.5%; 95% ci, 6.3-11.1). the seroprevalence of hev was notstatistically different between males and females or between different age groups.conclusions: hev is relatively prevalent in children that live in the southwest of iran, and further studies are needed toinvestigate the seroprevalence of hev in other age groups.
