  A class of reaction-diffusion virus dynamics models with intracellular
state-dependent delay and a general non-linear infection rate functional
response is investigated. We are interested in classical solutions with
Lipschitz in-time initial functions which are adequate to the discontinuous
change of parameters due to, for example, drug administration. The Lyapunov
functions technique is used to analyse stability of interior infection
equilibria which describe the cases of a chronic disease.
