1. Introduction
Continuous time deterministic epidemic models are traditionally for-
mulated as systems of ordinary differential equations for the numbers
of individuals in various disease states, with the sojourn time in a state
being exponentially distributed. Time delays are introduced to model
constant sojourn times in a state, for example, the infective or immune
state. Models then become delay-differential and/or integral equations.
For a review of some epidemic models with delay see van den Driess-
che [228]. More generally, an arbitrarily distributed sojourn time in a
