连云港市2007—2009年儿童急性弛缓性麻痹监测结果分析

目的分析连云港市2007—2009年儿童急性弛缓性麻痹(AFP)病例监测结果。方法应用Excel软件和中国免疫规划监测信息管理系统进行数据分析。结果连云港市2007—2009年分别报告AFP病例19、10和12例,报告发病率分别为1.55/10万、1.06/10万和1.27/10万。夏秋季节病例居多,4岁以下病例所占构成比为75.61%,服苗史≥3次的占90.24%。41例病例实验室培养结果显示,Ⅰ型、Ⅲ型脊灰病毒各1例阳性,均为脊灰疫苗株。AFP病例报告后48h内流调率、标本采集率、60d随放率及75d内送达率均为100%,粪便标本7d内送检率为97.56%,均达到相关要求。初到村级、乡级、县级及以上医院就诊的病例报告率分别为0、30.77%、70.83%。结论连云港市儿童AFP病例监测系统运转良好。但仍需提高监测灵敏性,做好常规免疫和AFP病例合格标本的采集工作,提高首诊报告率,有效维持无脊灰状态。

Surveillance Results of Children with Acute Flaccid Paralysis in Lianyungang City during 2007-2009

Objective ] To analyze the surveillance results of children with acute flaccid paralysis （ AFP ） in Liangyungang City dur- ing 2007 -2009.
