莒南县肾综合征出血热地理流行病学研究

Study on the Geographic Epidemiology of Haemorrhagic Fever with Renal Syndrone in Junan County,Shandong Province

目的 :探讨肾综合征出血热 (HFRS)地理分布及相关因素对该病发生、发展的影响。方法 :泊松分布、配合适度检验、秩和检验及直线相关技术。结果 :该县 1990～ 1999年HFRS年均发病率为 97.86 / 10万 ;所辖 2 5个乡镇均系高发疫区 ;HFRS病例在乡镇间或村庄间有明显聚集性 ,在河侧村边集中分布规律明显 ;发病率与海拔高度、林地面积呈负相关 ,与人口密度、耕地面积呈正相关 ;干冷气候发病人数明显增加。结论 :地理、气候因素对该病有明显影响。

Objective:In order to study the geographic distribution of Haemorrhagic Fever with Renal Syndrone (HFRS) and the function of correlation factors on this disease.Method:The data of the HFRS incidence in Junan county during 1990-1999 was analysed. Results:It showed that the annual incidence rate was 97.86/10 5 in these ten years. All the towns and townships were strong epidemic areas. The distribution of HFRS had an obviously clustering among the townships or villages. The most cases were concentrated in the side of villages closed to the river. The incidence rate showed a negative correlation with the elevation or the area of moodland, and a positive correlation with the poputation density or the cultivated area. The cases of HFRS concentrated clearly in the arid and cold climate. Conclusion:It was concluded that the incidence rate was closely related with the geography and the climate.
