Environmental model overview

The Epidemiological MODeling software (EMOD) environmental model is a stochastic, agent-based model designed to simulate environmental disease transmission, such as through contaminated water. The model is built upon the framework of the generic model. To use the environmental model, the configuration parameter Simulation_Type must be set to ENVIRONMENTAL_SIM.

Infectious individuals shed contagion into their environmental and this shed contagion decays over time. Individuals acquire new infections through a dose-response probability curve, and dose can be mediated by seasonal factors.

Finally, the model includes multiple interventions. Interventions can act on the environment, such as through improved sanitation and hygiene, food safety measures, and agricultural practices. Interventions may also act on the individual, through vaccination, and the environmental and individual interventions can be combined. See Campaign parameters for the full list of available options.
