【摘要】 [目的]了解四川省疟疾流行与蚊媒密度变化情况,为制定新的防治策略提供科学依据。[方法]根据地理分布和疟疾发病情况,选择名山县、合江县、宜宾县、沐川县、岳池县为疟疾监测县,开展发热病人血检、疟疾病例流行病学调查、媒介按蚊密度调查和分类鉴定等。[结果]2006～2009年监测地区疟疾发病率分别为0.079/万、0.073/万、0.019/万、0.017/万,呈下降趋势;4年共报告疟疾病例67例,其中本地病例13例,占19.40%,输入性病例54例,占80.60%;媒介按蚊密度较低,中华按蚊为优势蚊种。[结论]今后应加大监测工作力度,重点加强流动人口的管理和输入性疟疾的防控。更多还原

【Abstract】 [Objective]To understand the dynamic malaria situation and the anopheles density in Sichuan so as to make out suitable control measures.[Methods]Based on geographic distribution and the condition of malaria infections,mingshan county,hejiang county,yibin county,muchuan county and yuechi county were selected as the supervised counties in Sichuan province.Four fever patients were required to receive blood test.Epidemiological case investigation was performed for malaria patients with the malaria media indentified and classified.[Results]From 2006 to 2009,the incidences of malaria in the supervised counties were 0.079/10 000,0.073/10 000,0.019/10 000 and 0.017/10 000,respectively.The incidences were declined year after year.There were 67 malaria patients in 4 years,and local infected patients accounted for 19.40% of the total cases,while the import cases accounted for 80.60%.The mainly anopheles was anopheles sinensis.[Conclusion]It was necessary to intensify the surveillance of malaria.The management of floating population and the prevention and control of imported malaria should be strengthened.更多还原
