The biogeographical examination of rodent faunas associated with arenaviruses reveals two distinct patterns. Lymphocytic choriomeningitis (LCM) virus is associated primarily with a single murid species, Mus musculus, although it is also known to cause laboratory infections in other species. On the other hand, the arenaviruses from the Western hemisphere are associated exclusively with a large and diverse group of cricetid rodents. Studies to date, although limited, have not demonstrated their association with any other rodent groups, although in South America alone at least twelve other rodent families are known. Evidence at the present time indicates that Lassa virus is only associated with a common African rodent, Mastomys natalensis. From this limited evidence it is as yet difficult to determine whether Lassa virus will follow the pattern of the South American arenaviruses, most of which are known from several species of rodents, or that of LCM virus, which appears to be associated with only a single rodent species. In this paper, the history and structure of South American, Eurasian, and African rodent faunas are described.
对与沙粒病毒相关的啮齿动物区系进行生物地理学研究，揭示出两种不同的模式。淋巴细胞性脉络丛脑膜炎（LCM）病毒主要与单一的鼠科物种小家鼠相关，不过已知它也会在其他物种中引发实验室感染。另一方面，西半球的沙粒病毒仅与一大类多样化的仓鼠科啮齿动物相关。尽管迄今为止的研究有限，但尚未证明它们与任何其他啮齿动物类群有关联，尽管仅在南美洲就已知至少还有十二个其他啮齿动物科。目前的证据表明，拉沙病毒仅与一种常见的非洲啮齿动物——南非多乳鼠相关。基于这一有限的证据，目前尚难以确定拉沙病毒会遵循南美洲沙粒病毒的模式（其中大多数病毒可在几种啮齿动物物种中发现），还是遵循LCM病毒的模式（它似乎仅与单一啮齿动物物种相关）。本文描述了南美洲、欧亚大陆和非洲啮齿动物区系的历史与结构。
