Abstract: Inspired in part by a personal encounter with Covid-19, we consider two models for the spread of infection about a population of moving individuals. The emphasis is upon the case of post-infection immunity. Partial results for the existence (or not) of a pandemic may sometimes be proved via comparisons with branching processes and percolation processes. The principal difficulties lie in the combination of movement and immunity.
After a discussion of the relevant stochastic processes, the two basic models will be described and relevant results outlined. Two prominent open problems will be presented.
