背景肾综合征出血热（HFRS）是一种人兽共患传染病，其传播受气候、水库、职业等因素的影响。本文定量分析了颍上县1980- 1996年秋冬季节肾综合征出血热（HFRS）的发病率及其潜在危险因素。方法对该县秋冬季节的气候变量、鼠密度、秋粮产量与HFRS年发病率进行相关和回归分析。结果降水量、鼠密度、秋粮产量与HFRS年发病率呈负相关。鼠密度（r = 0.90，P0.000）、秋粮产量（r = 0.67，P = 0.01）与HFRS发病率相关。结论降雨量、鼠密度和秋粮产量可作为低洼疫区HFRS传播的预测因子。
Background Being a zoonosis, the transmission of haemorrhagic fever with renal syndrome (HFRS) is influenced by climatic, reservoir and occupational factors. This paper has quantified the incidence and potential risk factors of HFRS in Yingshang County, a low-lying epidemic focus of the disease in China.Methods Correlation and regression analyses were conducted among climatic variables, the density of mice, autumn crop production and annual incidence of HFRS during the autumn-winter seasons in the County over the period 1980-1996.Results Rainfall (r = -0.63, P = 0.009), the density of mice (r = 0.90, P 0.000) and autumn crop production (r = 0.67, P = 0.01) were statistically correlated with the incidence of HFRS. Multiple regression analysis indicated that these factors are potential predictors for HFRS transmission.Conclusions Rainfall, the density of mice and autumn crop production could be used as predictors of HFRS transmission in low-lying epidemic foci.
