个体之间的接触网络结构对传染病的传播有着深远的影响。使用一种新技术——接近感应无线电项圈——我们描述了塔斯马尼亚袋獾的接触网络。这种现存最大的有袋食肉动物受到一种新型传染性癌症的威胁。所有恶魔都连接在一个巨大的组件中，这将允许疾病从任何一个受感染的个体传播到整个网络。与许多人类疾病的接触网络不同，程度分布并不是高度聚合的。然而，经验派生的网络与随机网络不同。交配季节和非交配季节之间的接触网络有所不同，交配季节内男性与女性之间的联系更广泛，而交配季节之外女性与女性之间的联系频率更高。我们的结果表明，通过针对高度相关的年龄或性别类别来控制该疾病的潜力有限。
The structure of the contact network between individuals has a profound effect on the transmission of infectious disease. Using a novel technology - proximity sensing radio collars - we described the contact network in a population of Tasmanian devils. This largest surviving marsupial carnivore is threatened by a novel infectious cancer. All devils were connected in a single giant component, which would permit disease to spread throughout the network from any single infected individual. Unlike the contact networks for many human diseases, the degree distribution was not highly aggregated. Nevertheless, the empirically derived networks differed from random networks. Contact networks differed between the mating and non-mating seasons, with more extended male-female associations in the mating season and a greater frequency of female-female associations outside the mating season. Our results suggest that there is limited potential to control the disease by targeting highly connected age or sex classes.
