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 analyze and compare the national malaria surveillance data in Sichuan Province from 2006 to 2008 and the malaria epidemic report in the province to find out the characteristics and trends of malaria epidemic in Sichuan Province. Methods According to malaria incidence, media distribution and geographical location, we selected Junlisi County, Junfeng County, Fengfeng Town and Jiangshan District, Fangshan Town as the national malaria surveillance sites for malaria incidence and anti-mosquito measures And other surveys, conducted a density survey and classification of malaria vectors, blood tests on the “three hot” cases, malaria antibody levels were monitored in some of the population; and collected malaria prevention and treatment reports and national network of direct malaria epidemic in Sichuan at the same period Data for a comprehensive analysis. Results The number of malaria cases reported at the three monitoring sites in 2006-2008 were 17 cases, 3 cases and 0 cases respectively. The number of anopheles mosquito caught was 66, 20 and 28, of which 6 were An. Only one and the rest are Anopheles sinensis. The number of malaria cases reported in the province from 2006 to 2008 were 317 (0.38 / 100,000), 214 (0.25 / 100,000) and 133 (0.17 / 100,000) respectively, of which 64.35% were imported for malaria and 64.95% , 83.46%. Conclusion The results of monitoring sites are basically the same as those of the whole province. The incidence of malaria shows a low and declining trend year by year, indicating that the results of monitoring sites are representative and of guiding significance for the prevention and control of the province. Imported malaria has become a major risk factor in Sichuan Province.
