2011年贵州省麻疹实验室监测与质量控制分析

Surveillance and Quality Control of Laboratory for Measles in Guizhou Province in 2011

目的分析贵州省麻疹实验室的监测与质量控制状况,为制定消除麻疹策略和措施提供依据。方法收集贵州省2011年麻疹监测信息报告管理系统及麻疹实验室的监测数据,综合评价实验室各项监测指标。结果 2011年共报告疑似麻疹病例数563例,采集标本670份,散发病例血标本采集率为94.7%;确诊麻疹病例49例,其中实验室确诊45例,占麻疹病例的91.8%;实验室血清学结果 7 d及时报告率为87.5%。1起麻疹暴发得到确诊。2株麻疹阳性分离物经序列测定和分析均为H1基因型中的H1a基因亚型。质量控制均符合世界卫生组织(WHO)和国家麻疹实验室(NationalMeasles Laboratory,NML)要求。结论 2011年贵州省麻疹实验室各项监测指标良好,具有良好质量控制体系,为消除麻疹奠定了良好的实验室基础。

Objective To analyze the surveillance and quality control status of laboratory for measles in Guizhou province and provide a basis for adopting measures to eliminate measles. Methods To collect the monitoring da- ta of laboratory for measles from the surveillance system in Guizhou province from January to December 2011 and estimate the monitoring target for measles. Results A total of 563 cases with measles were reported during 2011, 670 sera samples were collected with a collection rate of 94. 7%. A sum of 49 suspected cases were qualified and the confirmed cases were 45 with a positive rate ofgl. 8%. The rate of serum specimen results re- ported within 7 days was 87.5%. One outbreak was diagnosed as measles in lab. Two strains of measles virus were successfully isolated and all were certified as Hl a genotype. Laboratory quality control met the require- ments of both WHO and National Measles Laboratory. Conclusion All the surveillance indicators of the measles laboratory in Guizhou were well qualified, and good laboratory quality control system was also set up, which provided important scientific basis for eradication measles.
