In this paper, an SCIRS epidemic model will be presented that takes into account immunity to the spread of COVID-19 and insurance parameter. We will investigate how the immune system affects the speed of disease spread by calculating the equilibrium points of the system and checking their local and global stability. Additionally, the occurrence of a Hopf bifurcation will be demonstrated. Also, the effect of insurance parameter on the incidence of the diseases will be considered. To predict the transmission of Covid-19, we will present a numerical simulation based on real data.
