  We consider a Human Immunodeficiency Virus (HIV) model with a logistic growth
term and continue the analysis of the previous article [6]. We now take the
viral diffusion in a two-dimensional environment. The model consists of two
ODEs for the concentrations of the target T cells, the infected cells, and a
parabolic PDE for the virus particles. We study the stability of the uninfected
and infected equilibria, the occurrence of Hopf bifurcation and the stability
of the periodic solutions.
