Abstract In order to understand, in terms of the epidemiology of a disease, the consequences of having a population which can recover from the disease back to a state of susceptibility and the additional effects of recovery to immunity, we have formulated and compared a series of models; each includes a biological feature known to occur in a real host-pathogen system. For example, vertical transmission of the disease or free living infective stages of the pathogen. Taken together, these models, in general, follow predictable patterns of behaviour. There are exceptions, but these can be explained in terms of some sort of density dependence or time delay written into the framework of the model.
