我们提出了一个COVID-19疾病传播的分区数学模型，特别关注超级传播者个体的传播率。我们计算了基本再生数阈值，研究了无病平衡点在基本再生数下的局部稳定性，并研究了模型对每个参数变化的敏感性.数值模拟显示了所提出的COVID-19模型对中国武汉爆发的适用性。(C)2020爱思唯尔有限公司保留所有权利。
We propose a compartmental mathematical model for the spread of the COVID-19 disease with special focus on the transmissibility of super-spreaders individuals. We compute the basic reproduction number threshold, we study the local stability of the disease free equilibrium in terms of the basic reproduction number, and we investigate the sensitivity of the model with respect to the variation of each one of its parameters. Numerical simulations show the suitability of the proposed COVID-19 model for the outbreak that occurred in Wuhan, China. (C) 2020 Elsevier Ltd. All rights reserved.
