湖北省洪涝灾区的气象因素与钩体病发病关系的研究

The Relationship Between Weather Factor and Prevalence of Leptospirosis in Flooding Areas

目的 探讨洪涝灾区的气象因素与钩端螺旋体病 (钩体病 )发病关系 ,控制洪涝灾区钩体病流行。方法选择仙桃市、枝江县作为调查点 ,调查 6～ 10月平均降雨量、年平均降雨量、6～ 10月平均气温、年平均气温和钩体病发病率。结果 仙桃市、枝江县 8月份钩体病发病数占总发病数的 75 .74% ,仙桃市 8月份降雨量与钩体病发病率呈显著性相关 ,相关系数为r =0 .72 (P <0 .0 1) ,其余因子与钩体发病率均无显著相关性。结论 仙桃市的钩体发病率与当地 8月份的降雨量有一定的相关性。

Objective Mastering the prevalence regulation to control epidemic of Leptospirosis in flooding areas. Methods The investigation was carried out in Xiantao,Zhijiang where the epidemic was serious, including the average rainfall and air temperature per year, the average rainfall and air temperature during 6 10 months and the incidence rate of Leptospirosis. Results 75.74% of cases happened in August in Xiantao and Zhijiang. There was positive correlation between the incidence rate and rainfall in August, r=0.72(P <0.01). The rest factors hadn′t significant correlation with the incidence rate. Conclusion The incidence rate of Leptospirosis is related to rainfall to a certain extent.
