EpiGrass: a simulator of epidemics over networks

A new network infection modeling tool has been released. This one goes beyond a number of tools for analyzing network epidemics by integrating with geographic data from GIS systems. I haven't used it yet, myself, but it looks like a useful tool with some interesting features. I'd be interested in hearing how flexible it is for various network topologies and worm propagation models.

EpiGrass is a simulator of epidemics over networks.  Its is a scientific tool created for simulations and scenario analysis in Network epidemiology. For an in depth description of Epigrass capabilities, please refer to the documentation.

EpiGrass can interact with the GRASS GIS from which it can obtain maps and other geo-referenced information. However, EpiGrass does not require an installation of the GRASS GIS for most of its features.

Epigrass is free-software, licensed under the Gnu public license (GPL).
