【摘要】 [目的]防止口服脊髓灰质炎减毒活疫苗(OPV)引起相关麻痹病例(VAPP)的发生。[方法]对日照市1991～1999年报告5例口服脊髓灰质炎疫苗相关病例(VAPP),进行流行病学调查分析。[结果]首次服苗者年平均发病率为17.89％/100万;以0～4岁服苗人次统计,平均年发生率为1.59/100万。发病性别男女之比为4:1。年龄为4～10月龄,均为第1次服苗,有4例发病前30d内有肌肉注射史,其中3例注射DPT。病毒分型:Ⅰ型1例,Ⅲ型1例,Ⅱ+Ⅲ型2例,Ⅰ+Ⅱ+Ⅲ型1例,服苗到发病平均潜伏期15～22d,60d后随访均残留麻痹。[结论]随着OPV的大量使用,VAPP的发生率也在不断上升,应引起高度重视,制定有效的防治措施。更多还原
