目的了解2004-2012年丽水市急性弛缓性麻痹(AFP)病例监测系统的运行情况,分析监测质量。方法监测15岁以下AFP病例,由专业人员对病例调查、采便和随访,在省级疾控中心对粪便标本进行病毒分离和鉴定;省AFP病例专家诊断小组对每例AFP病例进行最终分类;应用SPSS13.0和AFP监测信息报告管理系统对数据进行统计分析。结果 2004-2012年共报告AFP病例81例,按15岁以下儿童数年平均报告发病率为2.10/10万,男女之比为1.79∶1;多为单侧下肢麻痹,占80.25%;3次及以上脊灰糖丸疫苗接种史者占87.65%;冬春季发病较多;共分离到4株肠道病毒,阳性率4.94%,其中非脊灰肠道病毒(NPEV)2株,脊灰病毒(PV)2株(Ⅰ+Ⅱ型),脊灰病毒阳性率为2.47%,经国家疾控中心参比实验室核实均为脊灰疫苗相关株;双份合格粪便采集率100%,粪便及时送检率95.10%,病例48 h流调率100%;监测医院漏报率为10.00%。结论丽水市AFP监测质量较高,常规免疫接种率维持较高水平,同时应采取措施控制监测漏洞。
Objective To understand the operation status of AFP case surveillance system in Lishui city from 2004 to 2012 and analyze the quality of monitoring. Methods AFP cases under 15 years of age were monitored. Professionals investigated cases, collected faeces and followed-up cases. The samples were stained and identified by the provincial CDC. AFP cases were diagnosed by experts in each province for the final classification of AFP cases. The SPSS13.0 and AFP monitoring information report management system were used to analyze the data. Results A total of 81 cases of AFP were reported from 2004 to 2012. According to the average annual incidence rate of children under 15 years old was 2.10 / 100,000, the ratio of male to female was 1.79:1. Mostly unilateral lower limb paralysis was 80.25% And polio vaccination history accounted for 87.65% of the total, with more incidence in winter and spring. Four strains of enterovirus were isolated, the positive rate was 4.94%, of which two were non-polio enterovirus (NPEV), poliovirus (PV) strains (Ⅰ + Ⅱ type). The positive rate of poliovirus was 2.47%. All the poliovirus-related strains were confirmed by the reference laboratories of the National Center for Disease Control and Prevention. The double stool collection rate was 100% The detection rate was 95.10%, and the 48-h flow rate was 100%. The omission rate in monitoring hospital was 10.00%. Conclusion The quality of AFP monitoring in Lishui City is relatively high, and the routine vaccination rate is maintained at a high level. At the same time, measures should be taken to control the loopholes in monitoring.
