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 understand the incidence and reporting of acute flaccid paralysis (AFP) cases in Sichuan Province from 2011 to 2012 and evaluate the operation effect of AFP case surveillance system in this province. Methods AFP case surveillance system in Sichuan Province was used to describe the epidemiological method. Results A total of 832 AFP case surveillance systems were reported in Sichuan Province from 2011 to 2012, including 786 AFP cases and 46 non-AFP cases. Of the 786 AFP cases, 782 had poliomyelitis (poliomyelitis) excluded, one was clinically poliovirus and three were poliovirus vaccine-derived (VDPV). The annual average incidence of non-polio AFP cases in children <15 years old was 2.77 per 100 000. There were 155 counties (cities, districts and the same below) in the reported cases, accounting for 85.64% of the total counties in the province. Surveillance system within 48 h survey rate ≥ 99%, qualified stool specimen collection rate ≥ 94%, stool specimens within 7 d delivery rate ≥ 92%, 75 days follow-up table within the delivery rate of ≥ 93%, 28 days results of the separation Feedback Rate ≥ 93%. Conclusion The AFP case surveillance system in Sichuan province operated well and was sensitive and effective from 2011 to 2012. The monitoring indicators of the province reached the requirements of the World Health Organization and the Ministry of Health.
