在美国蒙大拿州中部和西部的六个地点确定了小型哺乳动物种群的动态和汉坦病毒抗体的流行情况。从 1994 年 6 月到 9 月，每月捕获 18 个活体诱捕网格。在一公顷的网格上，鹿鼠 (Peromyscus maniculatus) 的数量从 0 到超过 90 只不等。我们的放血技术对鹿鼠的生存没有明显影响。鹿鼠、草地田鼠（Microtus pennsylvanicus）和山艾田鼠（Lagurus curtatus）呈血清阳性。 471 只鹿小鼠中有 38 只 (8%)（范围为 0% 至 30%）汉坦病毒抗体血清呈阳性。血清阳性小鼠比血清阴性鹿小鼠年龄更大，月存活率更低。我们发现汉坦病毒抗体的流行率与人口密度之间没有关系。
Dynamics of small mammal populations and the prevalence of antibodies hantavirus were determined in six locations in central and western Montana (USA). Eighteen live-trapping grids were trapped monthly from June through September 1994. Deer mouse (Peromyscus maniculatus) populations ranged from 0 to over 90 on one-hectare grids. Our bleeding technique had no apparent effect on survival of deer mice. Deer mice, meadow voles (Microtus pennsylvanicus), and sagebrush voles (Lagurus curtatus) were seropositive. Thirty-eight (8%) (range, 0% to 30%) of 471 deer mice were seropositive for hantavirus antibodies. Seropositive mice were older and had lower monthly survival rates than seronegative deer mice. We found no relationship between prevalence of hantavirus antibodies and population density.
