目的：调查分析河南省淮河流域稻田型钩体病的流行规律及影响因素。方法：血清学检验采用显微镜凝集实验，病原分离选用ｋｏｒｔｈｏｆ 培养基。结果：淮河流域稻田型钩体病的流行规律表现：（１） 流行季节为６ 月至１１ 月，高峰在９ 月下旬或１０ 月上旬。病例以青壮年农民为主。（２） 临床表现复杂，主要有流感伤寒型、肺大出血型、黄疸出血型等。（３） 传染源主要为黑线姬鼠，携带菌群为黄疸出血群。（４） 当地稻田型钩体病的发病率与带菌鼠密度呈明显的正相关关系，与鼠密度、降雨量的多少无明显的相关关系。与鼠密度、降雨量的多少无明显的相关关系。结论：对淮河流域稻田型钩体病应采取针对性的防治措施如灭鼠、注射相应型别的钩体疫苗、加强个人防护、加强监测及预报等控制钩体病流行。
Objective: To investigate the epidemiology and influencing factors of rice leptospirosis in the Huaihe River Valley of Henan Province. Methods: Serological tests using microscope agglutination experiments, pathogen selection korthof medium. Results: The prevalence of rice leptospirosis in the Huaihe River Basin showed that: (1) The epidemic season was from June to November with the peak in late September or early October. Cases are mainly young farmers. (2) clinical manifestations of complex, mainly influenza typhoid type, pulmonary hemorrhage, such as jaundice bleeding. (3) The main source of infection is Apodemus agrarius, carrying bacteria flora for bleeding jaundice. (4) There was a significant positive correlation between the incidence of Leprosy disease and the density of infected rats, but not with the density and the amount of rainfall. There is no obvious correlation between the density and the amount of rainfall. Conclusion: Specific control measures such as rodent control, injection of the corresponding type of leptospira vaccine, strengthening personal protection, monitoring and forecasting, etc. should be taken to control the prevalence of leptospirosis in the paddy field leptospirosis in the Huaihe River Basin.
