我们从传染病控制的角度分析了英国鲑鱼养殖业的网络结构。我们首次将覆盖英格兰和威尔士的活鱼运输（或运动）数据与覆盖苏格兰的数据相结合，并包括代表河流，海水和通过每个农场或渔业站点附近的人类或动物媒介的本地传播的潜在传播的网络层。我们发现，7.2%的活鱼运输跨越英格兰-苏格兰边境，网络分析显示，87%的英格兰和威尔士节点和72%的苏格兰节点可以通过单独的活鱼运输从跨境连接到达。因此，从疾病控制的角度来看，不应孤立地考虑英格兰和威尔士以及苏格兰的接触结构。我们还表明，大型流行病需要活鱼运动网络，因此针对运动的控制策略可能非常有效。虽然仅在活鱼运输网络上发生大规模流行病的风险相对较低，但由于多个网络层的相互作用，潜在风险大大增加。
We analyse the network structure of the British salmonid aquaculture industry from the perspective of infectious disease control. We combine for the first time live fish transport (or movement) data covering England and Wales with data covering Scotland and include network layers representing potential transmission by rivers, sea water and local transmission via human or animal vectors in the immediate vicinity of each farm or fishery site. We find that 7.2% of all live fish transports cross the England-Scotland border and network analysis shows that 87% of English and Welsh nodes and 72% of Scottish nodes are reachable from cross-border connections via live fish transports alone. Consequently, from a disease-control perspective, the contact structures of England and Wales and of Scotland should not be considered in isolation. We also show that large epidemics require the live fish movement network and so control strategies targeting movements can be very effective. While there is relatively low risk of widespread epidemics on the live fish transport network alone, the potential risk is substantially amplified by the combined interaction of multiple network layers.
