Objective : The incidence of hepatitis A virus (HAV) infection in childhood has dramatically declined, and therefore the susceptibility of adult to HAV is increasing in Korea. The purpose of this study is to evaluate the prevalence of anti-HAV IgG in children and adolescents in Gyeonggi Province.
Methods : 172 children and adolescents with no history of transfusion of any blood products during recent 1 year were enrolled. They were classified into 3 groups such as; 3~6 years, 10~11 years, and 17~18 years. Positive rates of anti-HAV IgG were determined by chemiluminescence immunoassay.
Results : According to age group, the seropositive rates were 0%(0/38), 0%(0/82) and 1.9%(1/52) in 3~6, 11~12, and 17~18 years of age group respectively.
Conclusion : Prevalence of Anti-HAV IgG in children and adolescents is nearly zero in our study. We recommend the HAV vaccination for young children.
