[目的]分析福建省登革热流行的影响因素,为防制提供依据。[方法]选择不同地区35个村为调查点,对调查点的地理环境类型、人口密度、往返东南亚地区的流动人口、白纹伊蚊幼虫密度、防蚊设施使用率、输入性登革热病例6项社会和自然因素进行logistic回归分析。[结果]输入性登革热病例,白纹伊蚊幼虫密度和往返东南亚地区的流动人口3个变量被选入回归方程,其相对危险度分别约为9.8、7.3和5.6。[结论]在有往返东南亚地区流动人口,有登革热输人病例,且白纹伊蚊幼虫密度高的地区,发生登革热流行的危险性较大。
[Objective] To analyze the influencing factors of dengue fever epidemic in Fujian Province and provide basis for prevention and control. [Method] 35 villages in different areas were selected as survey sites. The types of geographical environment, population density, migratory population from Southeast Asia, density of Aedes albopictus larvae, mosquito utilization rate, 6 cases of imported dengue fever Social and natural factors were logistic regression analysis. [Results] The three variables of imported dengue fever, density of Aedes albopictus larvae and floating population traveling to Southeast Asia were selected into the regression equation, and their relative risks were about 9.8, 7.3 and 5.6, respectively. [Conclusion] There is a high risk of dengue epidemics in floating population from south-east Asia, cases of dengue fever, and high density of Aedes albopictus larvae.
