Epidemiological model of infectious disease

Outbreak simulates disease dynamics under an individually base model of transitions among susceptible, exposed, infectious and recovered individuals. Outbreak provides several options for modes of transmission (random contact within populations, spatially based transmission, contact with environmental sources of disease) and provides options for management through vaccination or culling. The current version 2 of Outbreak was written by Robert Lacy, based on Outbreak version 1 designed by JP Pollak, PS Miller, RC Lacy, L Hungerford, and P Bright.
