Mathematical Modelling of the Dynamics of COVID-19 Pandemic COVID-19大流行动态的数学建模

A mathematical model to describe the dynamics of COVID-19 was formulated and analysed. The model is aimed at addressing the peculiarities of the dynamics of COVID-19 as identified by researchers as much as possible. Standard analysis indicates the existence of a disease-free equilibrium for the model which is locally-asymptotically stable when the basic reproduction number is less than unity. Conditions for the existence and stability of the endemic equilibria were determined. A backward bifurcation was found to be possible and triggered by the clinical progression of symptoms from asymptomatic to mild and to severe symptoms. Numerical simulation shows no significant difference in the dynamics of the asymptomatic and those with mild symptoms. The result also also shows that strict enforcement of quarantine can help contain the disease. © 2021 Asia Pacific Journal of Mathematics.
建立了描述COVID-19动态的数学模型并进行了分析。该模型旨在尽可能多地解决研究人员确定的COVID-19动态特性。标准分析表明，当基本繁殖数小于1时，该模型存在局部渐近稳定的无病平衡点。确定了地方性平衡存在和稳定的条件。发现后向分叉是可能的，并由症状从无症状到轻度和严重症状的临床进展触发。数值模拟显示，无症状和轻度症状患者的动态变化无显著差异。研究结果还表明，严格的检疫措施有助于控制疫情。©2021亚太数学杂志。
