Stochastic dynamics of the COVID-19 epidemic via a new mathematical model 基于新数学模型的COVID-19流行随机动力学

This work considers a new stochastic mathematical model for the transmission dynamics of the coronavirusCOVID-19 by providing the healthy compartment together with the quarantine/isolation compartment. In the deterministic model, global stability conditions of the disease-free equilibrium E0 and the endemic equilibrium E*are derived in terms of the threshold quantity Rd0. Based on the chaotic behavior, we develop and analyze a fourdimensional stochastic COVID-19 epidemic model. Uniqueness, boundedness, and positiveness of the proposed stochastic model are investigated in a biologically feasible region. In terms of the stochastic basic reproduction number Rs0 of the stochastic model, extinction and persistence of the COVID-19 disease are derived. Our theoretical findings are supported by some numerical simulations. The sensitivity of the model with respect to the parameters involved in the system is studied to investigate the most sensitive parameter towards the highest number of infected individuals. We confirm the stability analysis by showing the elasticity of Rs 0 with respect to the variation of each parameter. We present real data of a case study with the first wave of the COVID-19 epidemic in the United Kingdom. We compare our numerical results with the real data. © 2023 L&H Scientific Publishing, LLC.

本文提出了一种新的冠状病毒covid -19传播动力学的随机数学模型,该模型提供了健康隔间和检疫隔离隔间。在确定性模型中,用阈值r0导出了无病平衡点E0和地方病平衡点E*的全局稳定条件。基于混沌行为,建立并分析了一个四维随机COVID-19流行模型。研究了该随机模型在生物可行区域内的唯一性、有界性和正性。根据随机模型的随机基本再现数Rs0,导出了COVID-19疾病的灭绝和持续。我们的理论发现得到了一些数值模拟的支持。研究了模型相对于系统中涉及的参数的敏感性,以找出对感染个体最高数量最敏感的参数。我们通过显示Rs 0相对于每个参数的变化的弹性来确认稳定性分析。我们提供了一个案例研究的真实数据,其中包括英国第一波COVID-19流行病。我们将数值计算结果与实际数据进行了比较。©2023 L&H科学出版有限责任公司版权所有。
