Age-Structured Model Demographics A mathematical model which divides a population into different age classes in order to evaluate the effects of age-dependent infection, morbidity or mortality rates or age-specific vaccination schedules, and other factors. ...

In this chapter we apply the results obtained in the previous chapters to age-structured models. In Section 8.1, a Hopf bifurcation theorem is established for the general age-structured systems. Section 8.2 deals with a susceptible-infectious epidemic model with age of infection, uniform persistence...

Here we present an age-structured model for the immune response to an HBV infection, which takes into account contributions from both cell-mediated and humoral immunity. The model has been validated using published patient data recorded during acute infection. It has been adapted to the scenarios ...
