摘要
目的 探讨广西3个低疟区县疟疾监测措施和效果。方法 在上思县、全州县和天峨县,采用定点、定时（19：00~22：00）、定人室外人诱和室内早晨（5：00~7：00）50床蚊帐内捕蚊,计算媒介蚊虫叮人率。对发热患者血检疟原虫侦查传染源,用常住居民发热患者血检疟原虫阳性率和低年龄儿童疟疾抗体阳性率评估防治效果。结果 上思、全州和天峨3个县,疟疾发病率从2005年的0.15/万下降至2013年的0.14/万;常住居民发热患者血检疟原虫阳性率从2005年的0.004%（1/24 949）下降至2007年的0%（0/11 249）,2008~2013年未发现本地感染疟疾病例和输入性疟疾二代病例。但是,当地疟疾传播媒介依然存在。结论 疟疾监测措施有效,早期发现治疗传染源是控制疟疾传播的关键。
Objective To assess the measures and results of malaria surveillance in three low malaria-malria endemic counties in Guangxi. Methods Mosquitoes were captured by outdoor human baiting at fixed sites and at19：00-22：00 in the evening and indoor human baiting at 5：00~7：00 in the morning with bed net trapping. The man-biting rate of the mosquitoes was cal culated , the source of infection was traced by examinating blood samples from feverish cases. The results were assessed based on the plasmodium positive rate of feverish permanent residents and the antibody positive rate of low age children. Results Malaria indence rate dropped down from 0.15/10 000 in 2005 to 0.14/10 000 in 2013 among three counties of Shangsi Quanzhou and Tianer, the plasmodium positive rate of feverish permanat residents dropped down from 0.004%（1/24 949 ）in 2005 to 0% （0/11 249） in 2007. No local malarias infections and secondary cases due to imported malaria were reported from 2008-2013. But there were malaria vectors in the three counties. Conclusion Malaria surveillance measures adopted were effective and the early detection and treatment of source of infection are key measures for controlling the spread of malaria.
