摘　　要：目的　阐明贵州省肾综合征出血热 (HFRS)不同类型疫源地之间的相互关系。方法运用流行病学监测的技术方法 ,在不同类型疫源地连续进行多年监测。结果　在定点监测中 ,姬鼠型疫源地遵义县黑线姬鼠平均带病毒率为 3.39%、褐家鼠为 1.6 1% ,家鼠型疫源地石阡县褐家鼠平均带病毒率为 3.19%、黑线姬鼠不带病毒 ,显示姬鼠、家鼠型两类疫源地相对稳定。但开阳县落旺河桥两岸即东岸姬鼠型和西岸家鼠型疫源地类型在缓慢变化 ,1983～ 1984年间西岸的黑线姬鼠未检出HFRS病毒抗原 (0 99) ,1995～ 1998年间的黑线姬鼠感染率为 13.85 % (抗原 1 6 5 ,抗体 8 6 5 )。结论姬鼠、家鼠型两类疫源地在相对稳定中出现缓慢变化 ,相邻的姬鼠、家鼠型疫源地相互渗透形成疫源地重叠而成为混合型疫源地。Objective To explore the relations between different areas on hemorrhagic fever with renal syndrome (HFRS) in Guizhou. Methods Various forms of infectious areas were surveyed continuously through epidemiologic surveillance system. Results In fixed areas under surveillance system, the mean positive rate of HFRSV among Apodemus agrarius was 3.39 %, comparing with Rattus norvegicus 1.61 % in Apodemus infectious areas of Zunyi county, 3.19 % in Rattus norvegicus , but no HFRSV of Apodemus agrarius was identified in Rattus infectious area of Shiqian county. Both Apodemus and Rattus infectious areas were relatively stablized. In both banks of Luowang river, Kaiyang county, which had been identified as areas of infections for Apodemus in the eastern part, Rattus infectious area in the west, slow change was noticed. In 1983- 1984 was not found in Apodemus agrarius HFRSV, however the infectious rate of HFRSV in Apodemus agrarius was 13.85 % (Ag 1/65, Ab 8/65) in the western part of the province in 1995- 1998. Conclusion Both Apodemus and Rattus infectious areas were stabilized but changed slowly. Mixed type and the result of mutual penetration were noticed.
