We develop a model for the spatial spread of epidemic outbreak in a geographical region. The goal is to understand how spatial heterogeneity influences the transmission dynamics of the susceptible and infected populations. The model consists of a system of partial differential equations, which indirectly describes the disease transmission caused by the disease pathogen. The model is compared to data for the seasonal influenza epidemics in Puerto Rico for 2015-2016.

模拟地理区域的疫情暴发：波多黎各的季节性流感

我们开发了一个流行病在地理区域中的空间传播模型。目的是了解空间异质性如何影响易感人群和感染人群的传播动力学。该模型由偏微分方程系统组成，该系统间接描述了由疾病病原体引起的疾病传播。该模型与波多黎各2015-2016年季节性流感流行的数据进行了比较。
