Basics Group individuals into categories; figure out the rates at which various events (infection, recovery, death, etc.) occur, and how they move individuals between categories/change the population sizes; write down equations based on these rates. “All models are wrong but some are useful” (Tukey), but they can help us figure out the rate of spread, or the equilibrium prevalence. Some distinctions: micro- or macroparasite? Include vital dynamics (birth/death)? Life cycle (direct, vect...
