EpiGrass (epigrass.sourceforge.net) is a platform for network epidemiological simulation and analysis. It enables researchers to perform comprehensive spatio-temporal simulations incorporating epidemiological data and models for disease transmission and control in order to create sophisticated scenario analyses. Epigrass is a pure python application and plans to stay that way. It is supported on linux only but wellcomes volunteers willing to try to make it run on other platforms. enjoy! Flávio Codeço Coelho
