目的 研究洪涝灾害对钩端螺旋体病流行的影响 ,以便制定对策控制钩端螺旋体病的流行。方法 采取回顾性研究和现况研究相结合的方法 ,通过法定传染病报告系统收集发病情况 ,在相关单位收集水文气象资料 ,按全国爱卫办颁布的鼠密度调查方法开展鼠情监测。将获得的资料进行直线相关等统计学分析。了解气象水文等洪涝灾害和钩端螺旋体病发病之间的关系、水文气象与鼠类密度之间的关系、鼠密度和钩端螺旋体病发病之间的关系。结果 长江水位与钩端螺旋体病发病和流行无相关关系 ,鼠密度与钩钩端螺旋体病发病率呈正相关。当野外鼠密度大于10 % (夹夜法 )可引起钩钩端螺旋体病流行。结论 鼠密度可作为钩端螺旋体病监测和疫情预测预报的一项重要项目和指标。
Objective To study the impact of floods on the epidemic of leptospirosis in order to make countermeasures to control the prevalence of leptospirosis. Methods The retrospective study and current research were combined to collect the incidence through the legal infectious disease reporting system. Hydrological and meteorological data were collected at the relevant units and rodent surveillance was conducted according to the rat density survey promulgated by the National AIDS Health Service. The data obtained will be linear correlation and other statistical analysis. Understanding the relationship between meteorological hydrology and other flood disasters and the incidence of leptospirosis, the relationship between hydrrometeorology and the density of rodents, the relationship between the rat density and the incidence of leptospirosis. Results There was no correlation between the Yangtze River water level and the incidence and prevalence of leptospirosis. There was a positive correlation between the rat density and the incidence of leptospirosis. When the density of wild rats is greater than 10% (Jiaying method) can cause the hook leptospirosis epidemic. Conclusion Rat density can be used as an important project and indicator for the monitoring of leptospirosis and forecasting of epidemic situation.
