接触模式表征的信息含量与流行病爆发的可预测性

Information content of contact-pattern representations and predictability of epidemic outbreaks

Petter Holme

摘要:

了解人群的接触模式--谁与谁接触,以及接触发生的时间--对于传染病爆发的建模至关重要。传统的理论流行病学假设,任何人都可以以相等的概率遇到任何人。一种更现代的方法,网络流行病学,假设人们连接到一个静态的网络,疾病通过这个网络传播。较新的时间网络流行病学,包括接触表示中的时间。在本文中,我们研究的效果,这些连续的包含更多的信息。使用经验接近数据,我们研究了未知来源的爆发规模,并从已知状态的持续爆发。在第一种情况下,从完全混合模拟到网络,以及从网络到时间网络,存在很大的差异。在第二种情况下,差异较小。我们解释这些意见的时间网络结构的数据集。例如,节点和链接的快速翻转似乎使时间信息更加重要。

英文摘要:

To understand the contact patterns of a population -- who is in contact with whom, and when the contacts happen -- is crucial for modeling outbreaks of infectious disease. Traditional theoretical epidemiology assumes that any individual can meet any with equal probability. A more modern approach, network epidemiology, assumes people are connected into a static network over which the disease spreads. Newer yet, temporal network epidemiology, includes the time in the contact representations. In this paper, we investigate the effect of these successive inclusions of more information. Using empirical proximity data, we study both outbreak sizes from unknown sources, and from known states of ongoing outbreaks. In the first case, there are large differences going from a fully mixed simulation to a network, and from a network to a temporal network. In the second case, differences are smaller. We interpret these observations in terms of the temporal network structure of the data sets. For example, a fast overturn of nodes and links seem to make the temporal information more important.
