广西疟疾监测措施研究

Studies on surveillance measures of malaria in Guangxi Province,China

目的探讨广西基本消除和消除疟疾地区疟疾监测措施及其效果,为制订疟疾监测方案提供依据。方法采用病原学、血清学和昆虫学同步综合监测方法,对监测点发热病人血检疟原虫;小学生取滤纸血用IFAT测定疟疾抗体水平;半通宵(19:00～22:00)室外人诱捕蚊加早晨(5:00～7:00)50床蚊帐内捕蚊观察叮人率。结果监测点3个乡(镇)平均疟疾发病率和血检疟原虫阳性率2005年分别为0.69/万和0.26%,至2007年均下降为0;小学生年平均疟疾抗体阳性率为0.25%;3年间监测点未发生输入疟疾继发病例。结论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 probe malaria surveillance measures and effects in the areas where malaria has basically eliminated and have been eliminated. Methods The parasite was examined in blood from fever cases, primary school students filter paper blood examined in the survey sites by IFAT of malaria antibody level, adopting the ways of aetiology, serology and entomological of synthetically surveillance.Vectors using man entices mosquitoes at half night （19：00-22：00） and catching mosquitoes in fifty nets in the morning （5：00-7：00） to observe man-biting rate. Results Annual malaria incidence and plasmodium positive rate dropped down from 0.69 and 0.26% in 2005 to zero in 2007 at three survey villages（towns）, annual average malaria antibody of primary school students positive rate was 0.25%.Imported malaria continued cases haven＇t been happened at the surveillance sites for three years. Conclusion The focus of infection has been found in early stage and cured radically without delay was the crux measures to control malaria spreading.
