Epidemiological Analysis of Acute Flaccid Paralysis During 2011-2012 in Sichuan and Evaluation on the Surveillance System

目的了解四川省2011-2012年急性弛缓性麻痹(AFP)病例发病与报告情况,评价该省AFP病例监测系统运转效果。方法利用四川省AFP病例监测系统资料,采用描述流行病学方法进行分析。结果四川省2011-2012年AFP病例监测系统共报告832例,其中AFP病例786例,非AFP病例46例。786例AFP病例中,782例排除脊髓灰质炎(脊灰),1例为临床符合脊灰病例,3例为脊灰疫苗衍生病毒(VDPV)病例。<15岁儿童非脊灰AFP病例年平均报告发病率为2.77/10万,报告病例的县(市、区,下同)155个,占全省总县数85.64%。监测系统48 h内调查率≥99%、合格粪便标本采集率≥94%、粪便标本7 d内送达率≥92%、随访表75 d内送达率≥93%、分离结果 28 d内反馈率≥93%。结论 2011-2012年四川省AFP病例监测系统运转良好、敏感有效,全省各项监测指标均达到世界卫生组织和卫生部的要求。

Objective To study the incidence and reporting status of acute flaccid paralysis （AFP） cases during 2011 -2012 in Sichuan province and evaluate the surveillance system. Methods Data collected from AFP surveillance system was analyzed by descriptive epidemiological method. Results A total of 832 cases were reported in AFP surveillance system during 2011 -2012, among which 786 were AFP case and 46 were non -AFP cases; 782 AFP cases were excluded as non -poliomyelitis; one cases were classified as being clinically polio - match case and another 3 cases were vaccine derived poliovirus （VDPV） cases. Annual average reporting incidence rate of non - polio AFP in children aged 〈 15 years old was 2.7/10^5. AFP cases were reported in 155 counties/districts, accounting for 85.64% of total provincial county numbers. The 48 - hour inspection rate was≥99% , the collection rate was≥94% , the delivery rate of the stool samples in 7 days was≥92% , the delivery rate of follow - up table in 75 days was≥93% and the feedback rate of the separation in 28 days was≥93%. Conclusion The operation status of AFP surveillance system during 2011 -2012 in Sichuan is in well- functioning, and also is sensitive and efficient; all surveillance indices have met the requirements of WHO and the Ministry of Health
