[目的]探讨四川省盐源县流行性出血热的危险因素。[方法]采用1︰1配对病例对照研究,通过回顾性问卷调查,获取盐源县流行性出血热的暴露因素。[结果]共调查了50对病例和对照。病例组和对照组的年龄无统计学差异(t=0.1759,P﹥0.05),可比性好。在P﹤0.05显著水平下,条件Logistic回归单因素分析和多因素分析均有统计学意义的因素为:家中有柴草堆或稻草堆(OR=4.2798,β=1.4539),吃过鼠接触过的东西(OR=3.5478,β=1.2663)和直接接触过家禽家畜的排泄物(OR=3.9519,β=1.3742)。[结论]家中有柴草堆或稻草堆,吃过鼠接触过的东西,直接接触过家禽家畜的排泄物可能是盐源县流行性出血热发病的危险因素,这对当地EHF的综合防治有指导意义。
[Objective] To explore the risk factors of epidemic hemorrhagic fever in Yanyuan County, Sichuan Province. [Method] A 1: 1 matched case-control study was conducted to investigate the exposure factors of epidemic hemorrhagic fever in Yanyuan County by retrospective questionnaire. [Results] A total of 50 pairs of cases and controls were investigated. There was no significant difference in age between the case group and the control group (t = 0.1759, P> 0.05). At the significant level of P <0.05, the conditional logistic regression analysis showed that there were statistically significant factors in the univariate and multivariate analysis of logistic regression: the number of firewood or straw heap (OR = 4.2798, β = 1.4539) (OR = 3.5478, β = 1.2663) and excreta (P = 3.9519, β = 1.3742) that had been in direct contact with poultry and livestock. [Conclusion] There was a firewood or straw heap in the house, which had been touched by rats and had direct contact with the excrement of poultry and livestock, which might be the risk factor of epidemic hemorrhagic fever in Yanyuan County, which was instructive to the comprehensive prevention and treatment of local EHF. significance.
