目的 :阐明我国肾综合征出血热 (HFRS)不同类型疫源地相互之间的关系。方法 :选择有黑线姬鼠分布的家鼠型疫区 ,用流行病学监测方法 ,在黑线姬鼠种群中连续多年检测汉坦病毒感染情况。结果 :观察的家鼠型疫区黑线姬鼠不携带汉坦病毒。结论 :证明家鼠型HFRS疫源地不是由姬鼠型HFRS病原演变而成的 Objective: To clarify the relationship between different types of foci of Chinese hemorrhagic fever with renal syndrome (HFRS). Methods: The domestic mice infected with Apodemus agrarius were selected. The prevalence of Hantaviruses in the Apodemus agrarius population was detected by epidemiological surveillance methods. Results: The observed Apodemus agrarius did not carry Hantaan virus. CONCLUSIONS: It has been demonstrated that HFRS foci in mice are not evolved from the HFRS pathogen
