There are a numerous simulation toolkits available now days, requiring various levels of programming experience. One of these, the Repast toolkit, is a set of Java libraries for agent-based modeling (ABM). Repast is quite user-friendly, and many programmers already have experience with Java and C++.

         This paper demonstrates the design and implementation of an agent-based, spatially explicit simulation for the study of infectious disease in a human population witch is the Avian Bird Flu. The simulation is readily extensible for multiple applications within this area, and thus can be a good starting point for other researchers. It also demonstrates that the Repast libraries are sufficient to create a realistic, extensible system that is also easy to use for demonstration purposes and researchable topics. The system has enough flexibility and power to model epidemics with an outstanding capability to harness any task. The parameters offer enough detail to be useful for focused numerical experimentation. It is the team's hope that interested researchers will take this code, extend and modify it, and use it for their own research.
