本文提出了一个概念框架，以形式化的传染病流行病学的个人为基础的和空间明确的模型。该框架在假设、概念模型和模型结构方面不同于传统的基于人群的流行病学模型。特别是，作者讨论了四个方面的模型：（1）人口段或独特的个人作为建模单元，（2）连续过程或离散事件，以代表疾病的发展，通过时间，（3）行波或网络分散，以代表疾病的空间传播，（4）组内和组间的相互作用，以代表本地和长距离的传播。基于这些概念性的讨论，一个简单的流感流行模拟，以说明所提出的框架的应用。
This paper presents a conceptual framework to formalize an individual-based and spatially explicit model of the epidemiology of infectious diseases. The framework differs from that of the traditional population-based epidemiological models in terms of assumptions, conceptual models, and model structures. In particular, the author discusses four aspects of the model: (1) population segments or unique individuals as the modeling unit, (2) continuous process or discrete events to represent the disease development through time, (3) traveling wave or network dispersion to represent the disease transmission in space, and (4) within-group and between-group interactions to represent local and long-distance transmissions. Based on these conceptual discussions, a simple influenza epidemic is simulated in order to illustrate the application of the proposed framework.
