目的 :为总结四川省实现无脊灰目标的经验 ,探讨 AFP病例监测系统在实现无脊灰目标中的作用。方法 :对四川省 1991～ 2 0 0 0年 AFP病例监测系统所获资料与常规疫情报告资料进行对比分析。结果 :分析发现四川省自 1997年起 ,无论是 AFP病例监测系统还是常规疫情报告系统均无脊灰病例报告 ,但是 AFP病例监测系统采用被动与主动两套信息系统收集资料 ,两个系统资料相互映证与监督 ,并得到实验室的支持 ,所获数据在敏感性、特异性、及时性和完整性等方面均优于传统疫情报告系统。1991～ 2 0 0 0年 AFP病例监测系统共报告 AFP 2 35 4例 ,发现脊灰 2 81例 ,而常规疫情报告系统仅报告脊灰 2 0 5例。 1994～ 2 0 0 0年 AFP病例监测系统共采集大便标本 370 6份 ,共检出各型脊灰病毒 97株 ,检出毒株经国家脊灰实验室型内鉴定 ,均为疫苗株。结论 :本文结果表明我省已无脊灰野病毒在人间循环 ,AFP监测系统能为证实无脊灰提供依据
Objective: To summarize the experience of Sichuan in achieving polio-free targets and to explore the role of AFP case monitoring system in achieving polio-free targets. Methods: The data of AFP case surveillance system in Sichuan Province from 1991 to 2000 were compared with the data of routine epidemic situation reports. Results: The analysis showed no polio cases reported in Sichuan Province since 1997, both AFP case monitoring system and routine epidemic situation reporting system. However, the AFP case monitoring system adopted two sets of passive and active information systems to collect data. The two system data Mapping and monitoring, and supported by laboratories. The data obtained are superior to traditional epidemic reporting systems in terms of sensitivity, specificity, timeliness and completeness. AFP cases surveillance system from 1991 to 2000 reported AFP 2 35 4 cases, polio 2 81 cases, while conventional epidemiological reporting system only reported 205 cases of polio. A total of 370 6 stool samples were collected from 1994 to 2000 in AFP case surveillance system. 97 strains of poliovirus were detected. The strains were all identified as vaccine strains by the National Polio Laboratory Laboratory. Conclusion: Our results show that the province has no polio circulation in the world, AFP monitoring system to provide evidence to prove polio-free
