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。
Objective To analyze the monitoring results of children with acute flaccid paralysis (AFP) in Lianyungang during 2007-2009. Methods Data were analyzed by Excel software and China Immunization Program Monitoring Information Management System. Results AFP cases 19, 10 and 12 cases were reported in Lianyungang from 2007 to 2009 respectively. The reported incidence rates were 1.55 / 100000, 1.06 / 100000 and 1.27 / 100000 respectively. Most summer and autumn cases, the proportion of cases under the age of 4 accounted for 75.61%, service history of ≥ 3 times accounted for 90.24%. The results of laboratory culture in 41 cases showed that each of type Ⅰ and type Ⅲ poliovirus was positive in one case, all of which were poliovirus strains. Rate of flow transfer, specimen collection rate, 60 days follow-up rate and delivery rate within 75d were all 100% within 48h after the report of AFP, and 97.56% within 7 days after stool specimen reached the relevant requirements. At the beginning of the village, township, county level and above the hospital treatment rate of cases were 0,30.77%, 70.83%. Conclusion The AFP case monitoring system for children in Lianyungang is working well. However, monitoring sensitivity still needs to be improved, routine immunization and collection of qualified specimens of AFP cases are still needed, the first report rate is raised, and the polio-free status is effectively maintained.
