You need to be careful with the incidence data if the Gaussian model isn't appropriate, I assume that many counties have very low prevalence, so a count data model may be more appropriate. I would check out INLA, it will do Bayesian models over space and time, there are some tutorials/examples here: http://www.r-inla.org/examples <http://www.r-inla.org/examples>
