【摘要】 目的为了了解长春地区儿童甲型肝炎自然感染情况。方法采用竞争性抑制ELISA法检测甲型肝炎抗体。结果对417名儿童进行甲肝抗体检测,甲肝病毒抗体-IgG阳性176例,自然感染率为42.21%,学龄前儿童与学龄后儿童自然感染率分别为36.47%和63.64%,统计学分析差异显著,表明甲型肝炎的自然感染率学龄后儿童甲型肝炎的易感率较高。结论0~6岁儿童抗体水平较低,随着年龄的增长,甲肝抗体阳性率呈现上升趋势。更多还原

【Abstract】 Objective:To study the natural infectious rate of viral hepatitis A in children of Changchun area.Methods:Adopting competitive inhibition Enzyme-linked immunoadsordent assay(ELISA),we detected the antibody to hepatitis A in serum.Results:In 417 children,the positive rate of antibody to hepatitis A-IgG is 42.21%(176/417),the natural infectious rate of children preschool age and school age are 36.47% and 63.64%,respectively.There are the significant difference between children preschool age and school age.The susceptible rate of the natural infectious of viral hepatitis A in school age is higher than others.Conclusions:The level of antibody to hepatitis A in serum is lower between 0 and 6 ages.With the age increasing,the positive rate of IgG of antibody to hepatitis A show a rising tendency.更多还原
