Prevalence of anti-HAV and anti-HEV antibodies in Konya, Turkey
(ELSEVIER SCI IRELAND LTD, 2004) Atabek, ME; Fyndyk, D; Gulyuz, A; Erkul, I
Objective: To determine the prevalence of antibodies to hepatitis A (HAV) and E (HEV) Viruses in the different areas of Konya. Methods: Anti-HAV and anti-HEV antibodies were investigated in 210 healthy children randomly selected (100 from rural areas and 110 from urban areas of Konya). None gave a history of previous icterus nor other signs of hepatitis, had received blood transfusion and HAV vaccine, or had been on hemodialysis. Results: Evidence of HAV infection Occurred in children under the age of 6 years. The seroprevalence rate was 67.8% in rural areas and 25.8% in urban areas. This increased rapidly with age and became universal after 11 years of age in both areas. In contrast, HEV infections were not detected until children were 6-11 year olds, and the 5.2% seroprevalence rate ill urban areas and 8.5% seroprevalence rate in rural areas in this age group did not significantly increase in older age group. The prevalence of anti-HAV as well as anti-HEV was significantly higher in children with poor socio-economic conditions in both areas. Conclusions: These results Suggest that HAV infection in rural areas of Konya is widespread and that environmental and socio-economic factors play a major role in its transmission. In contrast, hepatitis E is not a public health problem in Konya. (C) 2003 Elsevier Ireland Ltd. All rights reserved.
