In vector-borne epidemic models there is often a substantial difference between the vector (usually insects) and host (usually humans) time scales. This makes it possible to view the model as a singular perturbation problem and use the quasi-steady state (equilibrium for the vector population in terms of the host population) to decompose the model into two problems of lower dimension and obtain a final size estimate for the epidemic.
