莒南县肾综合征出血热地理流行病学分析

目的：为探讨莒南县肾综合征出血热（HFRS）地理分布及相关因素对该病发生发展的影响。方法：对该县1991－2000年HFRS疫情资料进行分析。结果：该县HFRS10年的年均发病率为97．86／10万，所辖25个乡镇全部为高发疫区，HFRS病例在乡镇间或村庄间皆有明显聚集性，在河侧村边集中分布规律明显，发病率与海拔高度，林果面积呈负相关，与人口密度，耕地面积呈正相关，干冷气候发病率明显上升，结论：地理，气候因素对HFRS发病有明显影响。

ANALYSIS ON THE GEOGRAPHIC EPIDEMIOLOGY OF HAEMORRHAGIC FEVER WITH RENAL SYNDRONE

Objective:In order to study the geographic distribution of haemorrhagic fever with renal syndrone(HFRS) and the effect of correlation factors on this disease.Methods:The data of the HFRS incidence in Junan county during 1991~2000 was analysed.Results:The annual incidence rate of HFRS was 97.86/10~ -5 in these ten years.All the towns and townships were high-frequency areas.The distribution of HFRS had an obviously clustering among the townships or villages.The most cases were concentrated on the side of villages near the river.The incidence rate of HFRS 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 on the arid and cold climate.Conclusion:The incidence of HFRS was closely related with the geography and the climate.
