时间网络上SIR模型的快速和原理性模拟

Fast and principled simulations of the SIR model on temporal networks

Petter Holme

摘要:

易感-传染-传染(SIR)模型是传染病流行的经典模型,使人们在康复后免疫。计算流行病学中的许多开放性问题涉及潜在的接触结构对SIR模型等模型的影响。时间网络构成了一个理论框架,能够对网络中的结构进行编码,这些结构既可以是谁可以感染谁,也可以是这些接触发生的时间。在这篇文章中,我们讨论了这些模拟背后的详细假设-如何使它们与SIR模型的分析易于处理的公式相比较,同时尽可能真实。我们还为此目的提供了高度优化的开源代码,并讨论了尽可能快地制作程序所需的所有步骤。

英文摘要:

The Susceptible-Infectious-Recovered (SIR) model is the canonical model of epidemics of infections that make people immune upon recovery. Many of the open questions in computational epidemiology concern the underlying contact structure's impact on models like the SIR model. Temporal networks constitute a theoretical framework capable of encoding structures both in the networks of who could infect whom and when these contacts happen. In this article, we discuss the detailed assumptions behind such simulations -- how to make them comparable with analytically tractable formulations of the SIR model, and at the same time, as realistic as possible. We also present a highly optimized, open-source code for this purpose and discuss all steps needed to make the program as fast as possible.
