2、新发感染率,分析各年龄组EBV感染的性别和城乡特征。结果733例患儿进入分析,男414例,女319例。<1岁306例,~5岁193例,~l0岁147例,~17岁87例。~CA.IgG、NA—IgG和CA—IgM抗体的总阳性率分别为70.4%(516例)、68.4%(501例)和0.7%(5例);CA.IgG、NA—IgG的阳性率随年龄增长呈增高趋势;②<1、~5、一1O和~l7岁组EBV累计感染率分别为54.2%、74.6%、85.O%和90.8%;新发感染率分别为2.1%、2.4%、o和11.1%;③各年龄组男女性累计感染率差异无统计学意义;④各年龄组
3、CA.IgG抗体阳性率和累计感染率均呈现城区高于郊区的趋向,但差异无统计学意义。结论儿童EBV原发感染的年龄较早,l0岁时近90%的儿童血清EBV—CA.IgG抗体阳性,年龄较2o世纪80年代有所延迟。关键词EB病毒;血清流行病学;EB病毒抗体;儿童SerologicalepidemiologyinvestigationofEpstein-Barrvirusinfectionbasedon733childrentobeoperatedLIUYa-li,YAN如1g,GUANXiao-ld,AIJun-hong,XIEZheng-de(KeyLabora~
