目的探讨低疟区疟疾监测方法。方法对监测点常住人口和流动人口发热病人血检疟原虫,小学生疟疾抗体纵向监测,按蚊种类、主要传播疟疾媒介种群密度和叮人率调查。结果监测点疟疾发病率和常住人口发热病人血检原虫阳性率由2005年分别从0.69/万及0.02%下降至2009年均为零。结论当地疟疾流行得到有效控制,媒介依然存在,防止输入性疟疾传播是疟疾监测的重点。
Objective To investigate malaria surveillance methods in low malaria area. Methods A survey was conducted on malaria antibodies, primary malaria antibody surveillance, mosquito species and the prevalence of malaria vector population in the resident and migrant population in the monitoring sites. Results The positive rates of malaria and blood test in the resident population were reduced from 0.69% and 0.02% respectively in 2005 to zero in 2009. Conclusion The local malaria epidemic has been effectively controlled and the media still exist. Preventing the spread of imported malaria is the focus of malaria surveillance.
