In this paper, a fractional-order coinfection model for the transmission dynamics of COVID-19 and tuberculosis is presented. The positivity and boundedness of the proposed coinfection model are derived. The equilibria and basic reproduction number of the COVID-19 sub-model, Tuberculosis sub-model, and COVID-19 and Tuberculosis coinfection model are derived. The local and global stability of both the COVID-19 and Tuberculosis sub-models are discussed. The equilibria of the coinfection model are locally asymptotically stable under certain conditions. Later, the impact of COVID-19 on TB and TB on COVID-19 is analyzed. Finally, the numerical simulation is carried out to assess the effect of various biological parameters in the transmission dynamics of COVID-19 and Tuberculosis coinfection.
本文提出了一个用于描述新冠病毒（COVID-19）与结核病传播动力学的分数阶合并感染模型。推导了所提出的合并感染模型的正性和有界性。得出了COVID-19子模型、结核病子模型以及COVID-19与结核病合并感染模型的平衡点和基本再生数。讨论了COVID-19和结核病子模型的局部和全局稳定性。在某些条件下，合并感染模型的平衡点是局部渐近稳定的。随后，分析了COVID-19对结核病的影响以及结核病对COVID-19的影响。最后，进行了数值模拟，以评估各种生物学参数在COVID-19与结核病合并感染传播动力学中的作用。
