Analysis of a virus-immune system model with two distinct delays
A mathematical model describing the virus-immune system dynamics is studied. Stability criteria of the uninfected and the infected equilibrium point of the basic model is derived. Discrete time delays in different stages of infection propagation are incorporated and the delayed model is studied from a stability point of view. A critical value of the delay parameter which causes a stability change around the infected equilibrium is found out. Numerical studies are carried out to support analytical results.
