Abstract

Public health decision makers need to better understand the propagation of zoonoses. The currently available zoonosis simulations are based on compartment models which do not integrate the influence of geographic features on the species’ biological processes. In this context, we propose an approach that can generate an informed virtual geographic environment (IVGE) composed of a set of cells in which the evolution and interaction of the involved populations can be simulated plausibly. Since the number of these cells is huge, we propose a threshold-based merging algorithm that creates spatial subdivisions with the maximal size and suitability for a given biological phenomenon. Our approach also enhances each cell with qualitative and quantitative information such as the relative geographic orientation of the neighbors and the information about the distribution of individuals through trajectories. We used our IVGE to develop decision support tools that can simulate the spread of the West Nile Virus and Lyme disease.
