Abstract

In the present work we introduced and analyzed the most basic transmission SEI (susceptible-exposed-infective) model for a directly transmitted infectious disease caused by Coronavirus disease 2019 (COVID-19). The SEI model is modeling as a Markov chain and we computed a closed form formula of the mean first passage times (MFPT’s) vector arising from non-homogeneous Markov chain random walk (NHMC-RW) on the non-negative integers. Some particular cases, which lead to a relationship between the elements of the MFPT’s vectors. An efficient algorithm applied on mathematica program for computing MFPT’s vector of the NHMC-RW is given.

使用马尔可夫链的易感-暴露-感染模型
在本研究中,我们介绍并分析了由2019年冠状病毒病(COVID-19)引起的直接传播传染病的最基本传播SEI(易感-暴露-感染)模型。SEI 模型被建模为马尔科夫链,我们计算了非均质马尔科夫链随机游走(NHMC-RW)在非负整数上产生的平均首次通过时间(MFPT's)向量的封闭式公式。一些特殊情况下,MFPT 向量元素之间的关系。给出了一种应用于计算 NHMC-RW 的 MFPT 向量的高效算法。
