目的分析内蒙古巴彦淖尔市2008—2015年急性弛缓性麻痹(acute flaccid paralysis,AFP)病例的流行病学特征,评价AFP信息监测管理报告系统,为制定本地区预防AFP提供科学依据。方法采用描述性流行病学方法,对巴彦淖尔市2008—2015年15岁以下儿童AFP病例监测数据进行流行病学特征分析,并对AFP监测系统进行评价。结果巴彦淖尔市2008—2015年共报告15岁以下儿童AFP病例65例,年平均报告发病率3.20/10万,无脊髓灰质炎野毒株检出和脊髓灰质炎病例报告;发病时间以夏秋6—9月为多;临河区位居报告病例数首位,占总报告病例数的52.3%;男性多于女性,男女性别比为1.24∶1;1~<5岁儿童占总报告病例数的53.8%;完成全程免疫的儿童占61.0%,未完成免疫史和免疫史不详者占39.0%。各项监测指标均达到国家监测方案要求。结论巴彦淖尔市AFP监测系统灵敏性较高,AFP病例的监测应关注重点地区和重点人群免疫接种情况,继续保持无脊灰状态。

Objective To analyze the epidemiological characteristics and monitoring status of acute flaccid paralysis （AFP） cases from 2008 to 2015 in Bayannaoer City of Inner Mongolia, in order to provide the scientific basis in prevention from AFP.
