Early, reliable detection of outbreaks of disease, whether natural (e.g., West Nile virus) or bioterrorist-induced (e.g., anthrax and smallpox), is a critical problem today. It is important to detect outbreaks early in order to provide the best possible medical response and treatment, as well as to improve the chances of identifying the source. A primary goal of this project has been to develop new Bayesian models and inference algorithms that then are applied to monitor electronically available healthcare data to achieve early, reliable detection of outbreaks.

The scientific challenge of monitoring for outbreaks within an entire population creates major computational challenges in building and applying Bayesian models that are orders of magnitude larger than those developed previously. The project applied and extended state-of-the-art probabilistic inference methods to achieve efficient inference. If inference indicates that an outbreak is likely, an alert is raised automatically.

The scientific contributions of this project have involved developing, investigating, and evaluating new modeling and algorithmic techniques that make Bayesian biosurveillance practical for monitoring and diagnosing (in real time) the disease-outbreak status of an entire population.
