Abstract for: A Model of Population Movement, Disease Epidemic, and Communication for Health Security Investment
This paper outlines the formulation of a system dynamics model designed to compare investment alternatives intended to limit the onset and spread of human or animal disease. The model has been created to support the investment planning process for public health organizations worldwide, but also has relevance for public health systems research in general. It has been compiled from a sample of available generalized information as well as discussions with public health professionals. A scenario representing a common animal disease in a hypothetical developing country is used to demonstrate how the model can provide insight into investment impact. The details of the model structure are also discussed, which directly couples two well-known system dynamics constructs – the SEIR model and the population dynamics model – while adding a model of biosurveillance processes.
