目的了解勐腊县目前疟疾病例漏报情况,为制订疟疾防治计划及全球基金疟疾项目实施后的效果评价提供基线数据。方法用分层随机抽样,将抽取的乡(镇)村、杜疟疾发病,疾疫情报告等基础数据进行调查‰对居民2002年是否患过疟疾进行回顾性逐户逐人问卷记录。结果用以捕获一再捕获(CMR)方法,推算勐腊县2002年疟疾的发病人数为4 464例,是疫情报告数443例的10．1倍。疫情报告符合率仅为9．9％,漏报率达90．1％。结论目前勐腊县疟疾漏报数量大,疟疾发病形势严峻。因此,要加强疫情管理,加大疟疾防治力度,同时应引起各级政府、卫生行政部门高度重视。
Objective To understand the current situation of underreporting of malaria cases in Mengla County and provide baseline data for the evaluation of the effectiveness of malaria prevention and control programs and implementation of the Global Fund malaria project. Methods The stratified random sampling was used to investigate the basic data of township (village), incidence of malaria and epidemic situation report, etc. The retrospective household-by-patient questionnaire was recorded on residents who had malaria in 2002. The results were used to capture the recaptured (CMR) method. The number of malaria cases in Mengla County was estimated to be 4 464 in 2002, 10.1 times of the number reported in the epidemic situation. The coincidence rate of the epidemic report was only 9.9%, with a false negative rate of 90.1%. Conclusion At present, there is a large number of malaria omissions reported in Mengla County, and the incidence of malaria is grim. Therefore, it is necessary to strengthen the management of the epidemic and intensify efforts in prevention and treatment of malaria. At the same time, great attention should be given to all levels of government and health administrative departments.
