Stability analysis of a non-singular fractional-order covid-19 model with nonlinear incidence and treatment rate

Abstract In this paper, a non-singular SIR model with the Mittag-Leffler law is proposed. The nonlinear Beddington-DeAngelis infection rate and Holling type II treatment are used. qualitative properties of discussed in detail. local global stability analyzed. Moreover, some conditions developed to guarantee asymptotic stability. Finally, numerical simulations provided support theoretical results used analyze impact face masks, social distancing, quarantine, lockdown, immigration, disease, limitation resources on COVID-19. graphical show that effective rates significantly reduce infected population over time. contrast, availability raises population.
