Abstract: We propose in this thesis a new multi-level geosimulation approach to simulate the spread of a zoonosis (infectious disease transmitted from animals to humans) at different levels of granularity. This approach is characterized by using an original theoretical model named MASTIM (Multi-Actor Spatio-Temporal Interaction Model) which can be applied to simulate populations containing a huge number of individuals using extended compartmental models. MASTIM may specify not only the evolution of these populations, but also the aspects related to their spatio-temporal interactions, including their movements in the simulated georeferenced environment. Our multi-level geosimulation approach take advantage of an informed virtual geographic environment (IVGE) composed of a set of elementary cells in which the transitions of the different biological stages of the involved populations, as well as their interactions can be simulated plausibly. Furthermore, this approach has been applied to develop decision support tools. We got a first experience with the development of WNV-MAGS, a tool whose main purpose is to simulate the populations’ behavior of mosquitoes (Culex) and birds (crows), which are involved in the spread of West Nile Virus (WNV). We subsequently participated in the development of a generic tool (Zoonosis-MAGS) that can be used to simulate the spread of a variety of zoonoses such as Lyme disease and WNV. These tools may provide useful information to help public health officers to make informed decisions. Besides, we believe that this research can be applied not only to the spread of zoonoses, but also to other phenomena involving spatio-temporal interactions between different actors of different types.
