Concurrency and Reachability:
transmission in a dynamic network

preview image for Concurrency and Reacability movie

This five minute movie is a dynamic representation of an infection spreading through a transmission network over time. The data come from the National Longitudinal Survey of Adolescent Health. The animation uses a new method of network analysis to demonstrate that small differences in reported behavior can potentially explain the large racial disparities in HIV infection observed in the United States.
