新发传染病暴发时，媒体报道与医疗资源制约因素改变了传染病经典模型中的接触率和迁移率。本项目理论上给出其恰当的数学描述，构造合理的数学模型，研究媒体报道与医疗资源制约效应对新发传染病传播动力学过程的影响，揭示传染病在单个地区和多地区间的传播规律。主要研究内容为：(1)修正媒体报道影响下的接触率函数，研究媒体报道影响的新发传染病模型，揭示媒体报道对传染病传播动力学过程的影响；(2)建立媒体报道与医疗资源制约效应的新发传染病模型，探索两者对单个地区新发传染病传播规律的共同影响； (3)定量描述媒体报道影响下的迁移率函数，建立多地区媒体报道与医疗资源制约效应的新发传染病斑块模型，探索两者对新发传染病在地区间传播的共同影响。 该课题的研究为科学发挥媒体作用，合理分配各地区医疗资源以便有效控制新发传染病传播提供理论基础，对新发传染病传播预报的准确性和防治决策的科学性有重要意义。

It is a fact that both media coverage and medical resources will change the contact rate and dispersal rate in the classical epidemic models when new emerging infectious diseases outbreak in the modern society. In this project, we propose proper mathematical descriptions about media coverage and medical resource constraints, construct reasonable mathematical models, and investigate the impacts of media coverage and medical resource constraints. This research will shed light on the laws of disease spreading either in one or multiple regions.This project has the following three objectives: (1) to modify the contact rate function under the influence of media coverage, and investigate the epidemic models with media coverage to show the effects of media coverage on spreading of new emerging infectious diseases; (2) to propose mathematical models with media coverage and medical resource constraints, and discuss their joint influences on epidemic transmission in a single region; (3) to quantitatively describe dispersal functions under the influence of media coverage, establish multi-patch models with media coverage and medical resource constraints, and analyze their joint influences on epidemic transmission among regions. This study will provide the theoretical foundation for how to utilize the scientific role of media reports and how to rationally optimize the distribution of medical resources in order to control the spread of diseases effectively. This study is of great importance in both the accuracy of predictions and the scientific prevention decision of new emerging infectious diseases.
