目的分析1999～2007年钦南区疟疾监测情况,探索新的疟疾防治策略。方法对全区13个监测点的“三热”病人进行被动监测,采用吉氏染色-油镜进行血涂片检查;对流动人口进行主动监测,进行间接荧光抗体(IFA)实验的血清学检查。结果8年间钦南区共血检本地人群发热病人251456人;血检本地外出和外来流动人群发热病人5770人,分别检出本地流动外出回归人员和外来流动人员阳性病例各1例(为间日疟),阳性率分别为0.02%和0.08%;病灶点人群血检318人,均为阴性;血清学监测1304人,全部阴性。结论钦南区1999年以来疟疾带虫发病率一直控制在零以下,以输入性病例为主的特点。提示应继续加强对流动人口疟疾监测和控制力度,防止外源性疟疾输入,巩固疟疾防治成果。
Objective To analyze the status of malaria surveillance in Qinan District from 1999 to 2007 and explore new malaria control strategies. Methods Thirteen monitoring sites of the “three hot” patients in the district were monitored by passive biopsy using Giemsa staining - oil microscope for blood smears. The floating population was actively monitored and serums of indirect immunofluorescence assay (IFA) School inspection. Results A total of 251456 febrile patients were recruited in Qinan District during the 8 years. 5770 females were out-migrated and migrant in the floating population were detected in the Qinan District. One case of positive cases of returning migrants and floating migrants was detected Malaria). The positive rates were 0.02% and 0.08% respectively. There were 318 blood tests in the focus group, all of which were negative. There were 1304 serological surveillances, all of which were negative. Conclusion The incidence of malaria-borne insects in Qinan District has been controlled below zero since 1999, mainly on the basis of imported cases. It is suggested that the monitoring and control of malaria in floating population should be strengthened to prevent the import of exogenous malaria and to consolidate the results of malaria control.
