    The epidemiology of hepatitis a virus infection in children, in Edirne, Turkey
    (Springer, 2004) Erdogan, MS; Otkun, M; Tatman-Otkun, M; Akata, F; Türe, M
    Turkey is a middle endemic area with respect to Hepatitis A virus (HAV) infection. However, the frequency of this infection varies due to socioeconomic differences in various regions. The aim of this study was to detect the most likely age of exposure to HAV and factors affecting infection rates among children living in Edirne. A sample of 645 children between the ages of 0-19 living in Edirne were tested for total anti-HAV levels using ELISA method. A questionnaire on socio-economic status (SES), possible risk factors, and place of residence was completed for each child. Anti-HAV seropositivity was found to be 4.4, 25, 37.3 and 43.2%, in 2-5, 6-10, 11-14 and 15-19 age groups, respectively. Seropositivity was found to be increasing with age (p < 0.05). According to logistic regression analysis results; mother's education, SES of family, history of hepatitis in primary family members and the number of brothers or sisters were determined as factors increasing the seropositivity of HAV. Furthermore, HAV infection risk was found to be a decreasing function of income that is higher the income less likely the infection. These results showed that HAV infection rate in Edirne is in middle endemicity and the most likely way of exposure is transmission from family members. Although it requires further cost-effectiveness studies, our results indicate that applying the HAV vaccination in early childhood would be beneficial to decrease the prevalence of the infection and prevent HAV epidemics.

    Exposure time to hepatitis B virus and associated risk factors among children in Edirne, Turkey
    (Cambridge Univ Press, 2005) Otkun, M; Erdogan, MS; Tatman-Otkun, M; Akata, F
    Hepatitis B virus (HBV) infection is endemic in Turkey, but the main routes of transmission were not well established. This study aims to detect the exposure time to HBV and associated risk factors among children. In a sampling group of children aged 0-19 years living in Edirne, antiHBc, antiHBs and HBsAg were screened by the microELISA method. A questionnaire was also completed for each child. In 717 children that were included in the study, the total antiHBc seropositivity was 5.4% and was 1.8, 0.8, 1.7, 6.8, 11.8% in 0-1, 2-5, 6-10, 11-14, 15-19 years age groups respectively. The overall HBsAg seropositivity was 1.7%. The risk of HBV infection increased after the age of 10 years (OR 7.79, 95% CI 3.01-20.16). Collective circumcision was the only independent factor according to regression analysis. Children living in Edirne should be vaccinated against HBV before reaching 11 years of age.
