传染病传播的基于边的房室模型第一部分:综述

Edge-Based Compartmental Modeling for Infectious Disease Spread Part I: An Overview

Joel C. Miller, Anja C. Slim, Erik M. Volz

摘要:

预测传染病传播和干预有效性的主要工具是Kermack和McKendrick的群体行动易感-感染-传播模型。它的有用性主要来自其概念和数学上的简单性;然而,它错误地假设所有个体都有相同的接触率,并且接触是短暂的。本文是三个调查基于边缘的房室建模,消除这些假设的技术的第一。在本文中,我们推导出简单的常微分方程模型捕捉社会异质性(异质接触率),同时明确考虑接触时间的影响。我们引入了一个图形化的解释,允许容易推导和通信的模型。本文重点介绍了该技术以及如何在不同的环境中应用它。这两篇论文研究了如何为模型选择合适的复杂程度,以及如何将基于边的房室模型应用于具有各种子结构的群体。

英文摘要:

The primary tool for predicting infectious disease spread and intervention effectiveness is the mass action Susceptible-Infected-Recovered model of Kermack and McKendrick. Its usefulness derives largely from its conceptual and mathematical simplicity; however, it incorrectly assumes all individuals have the same contact rate and contacts are fleeting. This paper is the first of three investigating edge-based compartmental modeling, a technique eliminating these assumptions. In this paper, we derive simple ordinary differential equation models capturing social heterogeneity (heterogeneous contact rates) while explicitly considering the impact of contact duration. We introduce a graphical interpretation allowing for easy derivation and communication of the model. This paper focuses on the technique and how to apply it in different contexts. The companion papers investigate choosing the appropriate level of complexity for a model and how to apply edge-based compartmental modeling to populations with various sub-structures.
