A Time Delay Viral Micro Parasite Model

D. Appa Rao, S Kalesha Vali, A.V. Paparao


This paper deals with the dynamics of a micro parasite viral model which includes three compartments (susceptible(x), infective (y) and removable (z) populations). The total population is given by N = x + y + z. A time delay is incorporated in the interaction of susceptible and infective populations. The system is described by the couple of delay differential equations. The stability analysis is described at endemic equilibrium point. The existence of Hopf bifurcation is analysed using the time delay argument (τ).
