FRED (A Framework for Reconstructing Epidemiological Dynamics) is an agent-based modeling system developed by the Pitt Public Health Dynamics Laboratory.

FRED represents every person in a real geographic region as a separate individual each with her/his own unique social, familial, demographic, behavioral, and health characteristics. Individuals interact within realistic household, school, and workplace social networks.

FRED was originally developed to simulate infectious disease epidemics, but has been extended to enable users to model a wide range of health conditions and to study how patterns of those conditions vary over time in a specific region.

FRED produces a lot of analyzable data that is then used for visualizations. This web interface provides those visualizations in an interactive way in the hopes of making large-scale agent-based models more useful to the policy-making community, the research community, and as a teaching tool for students in public health.

FRED has been used for a variety of projects. See our Simulations menu for links to various project visualizations.
