‎For several decades researchers have been studying global dynamics of viral infection models to prevent wide outbreak of scattered virus both in population and vivo such as Dengue fever‎, ‎SARS-COV2‎, HRSV, ‎and immunodeficiency diseases‎. ‎In this paper‎, ‎our main aim is obtaining sufficient conditions for the global stability of equilibria of a Caputo fractional derivative order system with general incidence functional response by using Lyapunov ‎method and LaSalle's invariance principle‎. ‎We prove the global stability of stationary points by the values of the basic reproduction number {R_0} and we consider this threshold as a strong index for our sensitivity analysis‎‎. ‎We confirm theoretical results through numerical simulations.‎
