Conclusions: Raccoon Rabies Modeling

  1. Rabies entered Connecticut in 1991, and spread across the state in an epidemic wave. Rabies has now entered an endemic phase in Connecticut.

  2. Science seeks to explain pattern with process. We
    • observed the time series data,
    • deduced a pattern for the front, modeled with a modulated linear front;
    • used this model to obtain a pattern of local response;
    • reproduced the pattern using process-based model (Integro-differential equations, replaced by system of ODEs via restricted choice of kernel -- the "Linear Chain Trick").

  3. Present and future work:

    • refine delay equation solution(s) for local response (so that the fit is good and the parameters make sense!);

    • model kernel (find data, "mine" biologists)
