Time delays are often used to model mechanisms (e.g., the infective period) in the dynamics of epidemics. Such models can be formulated as functional differential and/or integral equations. A flavor of the modeling process and the mathematical tools used in the analysis is given. The ideas are illustrated by an SIS model in a variable size population with a constant delay corresponding to the infective period.
