An SCIRS epidemic model is presented in this study that incorporates disease immunity to analyze the spread of COVID-19. By determining the equilibrium points of the system and evaluating their local and global stability. The impact of the immune system on the transmission rate is examined. Addi- tionally, we introduce a Hopf bifurcation at the native equilibrium. The Adams-Bashforth- Moulton method is used to obtain numerical solutions for the model, along with a mathematical analysis. To predict the transmission of COVID-19, we conduct a numerical simulation using real-world data.
