目的探讨基本消除疟疾地区疟疾监测措施及效果,为制定疟疾监测方法及控措施提供依据。方法采用病原学、血清学及昆虫学方法,对“三热”病人血检疟原虫,小学生取滤纸血用IFAT测定疟疾抗体水平,通宵室外人工帐诱及灯诱监测按蚊种群和密度。结果 2010-2013年辖区医疗机构共血检“三热”病人19 958人次,发现疟原虫阳性3例。连续2年对学龄儿童疟疾抗体监测1 013人次,未发现阳性者。在2011-2013年按蚊监测中,仅2013年在白云区郊区捕获1只中华按蚊。结论加强疟疾监测、早期发现和及时根治传染源是控制疟疾传播的关键措施。
Objective To explore malaria surveillance measures and their effects in the area of malaria elimination and provide the basis for malaria surveillance methods and control measures. Methods The etiologic, serological and entomological methods were used to measure the levels of malaria antibodies in malaria parasites and primary school students by using the IFAT method. The anopheles population and density . Results From 2010 to 2013, a total number of 19 958 blood tests and 3 positive cases of Plasmodium were found in the medical institutions under their jurisdiction. Two consecutive years of school-age children malaria antibody monitoring 1 013 person-time, found no positive person. Anopheles sinensis was captured in the 2013-2013 Anopheles mosquito only in the suburbs of Baiyun District in 2013. Conclusion Strengthening malaria surveillance, early detection and timely cure of infection are the key measures to control the spread of malaria.
