Background: Hepatitis A is a common infectious disease during childhood worldwide. Recently, great deal of changes in the epidemiology has been reported. The seroepidemiologic studies of this infection are not sufficient in Eastern region of Turkey. Objective: To investigate the seroprevalence and association with socio-demographic variables of hepatitis A in 1-15 year old children in Van. Patients and Methods: This study was performed on 510 one to fifteen year old children from outpatient pediatric clinics in Yuzuncu Yil University, Faculty of Medicine during last three months of 2009. Anti-HAV IgG was measured in sera by enzyme-linked immunosorbent assay. The information about subjects was recorded on standardized forms and a chart review survey was performed.

Statistical significance was found between hepatitis A seroprevalence and age, collective use of domestic items, fresh water resources, localization and type of toilet and the number of households. Conclusion: This study provided the most recent data of seropositivity and revealed the preliminary indication of epidemiological shift in seroprevalence of Hepatitis A virus in a region with high endemicity.
