摘　　要：目的对2006-2008年四川省国家级疟疾监测点数据和全省疟疾疫情报告的分析比较,了解四川省疟疾流行特点和趋势。方法根据疟疾发病,媒介分布和地理位置等因素,分别选择筠连县巡司镇、青神县瑞峰镇和江阳区方山镇作为国家级疟疾监测点,进行居民疟疾发病情况、防蚊措施等调查,对疟疾媒介进行密度调查和分类鉴定,对"三热"病例进行血检,对部分人群进行疟疾抗体水平监测;并收集同期四川省疟疾防治工作报表及全国网络直报疟疾疫情数据进行全面分析。结果2006-2008年3个监测点报告的疟疾病例数分别为17例、3例和0例;捕获按蚊数是66只、20只和28只,其中嗜人按蚊数为6只、1只和1只,其余均为中华按蚊。2006-2008年全省报告的疟疾发病数分别为317(0.38/10万)、214(0.25/10万)和133(0.17/10万),其中输入性疟疾病例数分别占64.35%、64.95%、83.46%。结论监测点的结果与全省疫情基本一致,疟疾发病均呈现低且逐年下降趋势,表明监测点的结果具有代表性,对全省防治工作具有指导意义。输入性疟疾已成为四川省的主要危险因素。Objective To understand the characteristics and trend of malaria epidemic in Sichuan province by analyzing the data of national surveillance sites and from case reporting in the province. Methods According to the incidence, vector distribution and geographical characteristics of malaria, Xunsi town of Junlian county, Ruifeng town of Qingshen county and Fangshan town of Jiangyang county were selected as the national malaria surveillance sites. A series of investigations were carried out in these areas on the incidence of malaria among local people, anti-mosquito measures ; density and categories of vectors. Blood test was conducted for the patients clinically diagnosed as malaria, suspected to be infected with malaria or with fever of unknown origin, and surveillance of malaria antibody level was performed in some populations. The epidemic data were collected from monthly reporting forms of malaria in Sichuan and national disease direct network reporting system to conduct overall analysis. Results From 2006 to 2008, 17, 3 and 0 cases of malaria were reported in 3 surveillance sites respectively, and 66, 20 and 28 anopheles were caught, in which 6, 1 and 1 were Anopheles anthropophagus, the others were Anopheles sinensis. During 2006-2008, 317, 214 and 133 malaria cases were reported in the province with the incidence rate of 0. 38/100, 000, 0. 25/100,000 and 0. 17/100,000 respectively. Of all malaria cases, the proportions of imported malaria were 64.35% , 64.95%, 83.46%. Conclusion The malaria incidence in Sichuan province remained a very low level and might decrease gradually by year, to which the surveillance results in 3 surveillance sites was similar. The surveillance results indicated that data from the surveillance sites can generally reflect epidemic situation in the province and can be sued to guide or adjust current control strategies and activities. The imported malaria has become a major health problem.
