Stage-structured models of epidemics

Petra Klepac, Catherine Nosova

Epidemic models classify individuals by their infection status (infected, susceptible, recovered, etc.). Demographic models classify individuals by their demographic status (age, stage, reproductive status, etc.).  But epidemic processes can obviously depend on demographic status, and demographic processes can equally depend on infection status. This suggests the importance of stage-structured epidemic models, where the population changes over time in response to both kinds of processes. I am working on developing models for stage-structured epidemics, and for determining net reproductive numbers, perturbation analysis, and dynamic consequences.
