摘要
通过对经济、文化背景相似的长桥、漕河泾地区甲型肝炎 (甲肝 )疫苗 (HepA)接种和甲肝疫情资料分析 ,评价HepA免疫前后两地区甲肝发病率及年龄别发病率的变化。结果显示 :HepA免疫后 ,长桥地区 <2 5岁人群的甲肝发病率 (15 5 9/ 10万 )比漕河泾地区 (34 2 8/ 10万 )下降了 5 4 5 2 %。表明针对中小学生实施的HepA免疫对该人群的甲肝发病率下降是有影响的。
Through analysis of the data in 1990～1998 about hepatitis A (HA) immunization coverage rate and HA incidence of two residential areas, the Changqiao area and the Caohejin area, where the economic and the cultural backgrounds are similar, we evaluated the changes of incidence of hepatitis A and age distribution there before and after hepatitis A immunization. The results showed that HA incidence in Changgiao area (15.59/100,000) in 0～25 year old population decreased by 54.52% when compared with that of Caohejin area(34.28/100,000). Immunization with HA vaccine in primary schools of Xuhai District associated with declining of HA incidence.
