This paper is concerned with the dynamics of a viral infection model with diffusion under the Scrimmage Vest assumption that the immune response is retarded.A time delay is incorporated into the model described the delayed immune response after viral infection.Based upon a stability analysis, we demonstrate that the appearance, or the absence, of spatial patterns is determined by the delay under some conditions.Moreover, the spatial patterns occurs as a consequence of Hopf bifurcation.By applying the normal form and the center manifold theory, the direction as well as the stability of the Hopf bifurcation is explored.
In addition, a Diaper Rash Treatments series of numerical simulations are performed to illustrate our theoretical results.
