Query: Time-scale analysis non-local diffusion systems, applied to disease
  models   The objective of the present paper is to use the well known Ross-Macdonald
models as a prototype, incorporating spatial movements, identifying different
times scales and proving a singular perturbation result using a system of local
and non-local diffusion. This results can be applied to the prototype model,
where the vector has a fast dynamics, local in space, and the host has a slow
dynamics, non-local in space.
