几乎没有研究“谁从谁那里获得感染”的野生动物种群，但不同类的主机内和之间的传播模式很可能反映在时空分布的感染这些主机类。在这里，我们使用修改后的K-函数分析的形式来测试与牛痘病毒感染的银行田鼠和木鼠之间的时空相互作用。没有证据表明两种宿主物种之间存在传播，这支持了先前的证据，即它们是牛痘的独立宿主。在木鼠中，结果表明，传播主要发生在异性个体之间，这增加了牛痘在该物种中通过性传播的可能性。银行田鼠的结果表明，受感染的女性可能是一个更重要的感染源，无论是男性比。这两个物种的不同传播模式的建议本身与物种之间明显缺乏传播是一致的。
There have been virtually no studies of 'who acquires infection from whom' in wildlife populations, but patterns of transmission within and between different classes of host are likely to be reflected in the spatiotemporal distribution of infection among those host classes. Here, we use a modified form of K-function analysis to test for space-time interaction among bank voles and wood mice infectious with cowpox virus. There was no evidence for transmission between the two host species, supporting previous evidence that they act as separate reservoirs for cowpox. Among wood mice, results suggested that transmission took place primarily between individuals of the opposite sex, raising the possibility that cowpox is sexually transmitted in this species. Results for bank voles indicated that infected females might be a more important source of infection to either sex than are males. The suggestion of different modes of transmission in the two species is itself consistent with the apparent absence of transmission between species.
