Abstract

A mathematical model with environmental transmission has been proposed and analyzed to investigate its role in the transmission dynamics of the ongoing COVID-19 outbreak. Two expressions for the basic reproduction number R0 have been analytically derived using the next generation matrix method. The two expressions composed of a combination of two terms related to human to human and environment to human transmissions. The value of R0 has been calculated using estimated parameters corresponding to two datasets. Sensitivity analysis of the reproduction number to the corresponding model parameters has been carried out. Existence and stability analysis of disease free and endemic equilibrium points have been presented in relation with the obtained expressions of R0. Numerical simulations to demonstrate the effect of some model parameters related to environmental transmission on the disease transmission dynamics have been carried out and the results have been demonstrated graphically.

环境传播在COVID-19动态中的作用:基于数学模型的研究
本文提出并分析了具有环境传播的数学模型,以探讨其在当前新冠肺炎疫情传播动力学中的作用。用下一代矩阵法解析导出了基本再生数R0的两个表达式。这两个表达是由两个术语组合而成的,这两个术语涉及人与人之间的传播和环境对人的传播。R0的值是使用对应于两个数据集的估计参数计算出来的。进行了再现数对相应模型参数的敏感性分析。根据得到的R0表达式,给出了无病平衡点和地方病平衡点的存在性和稳定性分析。通过数值模拟,论证了与环境传播有关的一些模型参数对疾病传播动力学的影响,并对结果进行了图解说明。
