SIRS Epidemic Modelling Using Fractional-ordered Differential Equations: Role of Fear effect 基于分数阶微分方程的SIRS流行病建模:恐惧效应的作用

In this paper, an SIRS epidemic model using Grunwald–Letnikov fractional-order derivative is formulated with the help of a nonlinear system of fractional differential equations to analyze the effects of fear in the population during the outbreak of deadly infectious diseases. The criteria for the spread or extinction of the disease are derived and discussed on the basis of the basic reproduction number. The condition for the existence of Hopf bifurcation is discussed considering fractional order as a bifurcation parameter. Additionally, using the Grunwald–Letnikov approximation, the simulation is carried out to confirm the validity of analytic results graphically. Using the real data of COVID-19 in India recorded during the second wave from 15 May 2021 to 15 December 2021, we estimate the model parameters and find that the fractional-order model gives the closer forecast of the disease than the classical one. Both the analytical results and numerical simulations presented in this study suggest different policies for controlling or eradicating many infectious diseases.

本文利用非线性分数阶微分方程组,建立了一种基于格伦瓦尔德-列特尼科夫分数阶导数的SIRS流行病模型,用于分析致命传染病爆发时人群中的恐惧效应。在基本繁殖数的基础上推导和讨论了疾病传播或灭绝的标准。以分数阶为分岔参数,讨论了Hopf分岔存在的条件。此外,利用Grunwald-Letnikov近似进行了仿真,以图形化的方式验证了分析结果的有效性。利用2021年5月15日至2021年12月15日第二波印度COVID-19的真实数据,我们估计了模型参数,发现分数阶模型比经典模型更接近疾病的预测。本研究的分析结果和数值模拟都表明,控制或根除许多传染病的政策是不同的。《国际生物数学杂志》版权归世界科学出版公司所有,未经版权所有者明确书面许可,其内容不得复制或通过电子邮件发送到多个网站或发布到listserv。但是,用户可以打印、下载或通过电子邮件发送文章供个人使用。这可以删节。对副本的准确性不作任何保证。用户应参阅原始出版版本的材料的完整。(版权适用于所有人。)
