Effect of Work-related Mobility in the Simulation of Aerosol Anthrax Releases with BARD
Content Type: Abstract
An important problem in biosurveillance is the early detection and characterization of outdoor aerosol releases of B. anthracis. The Bayesian Aerosol Release Detector (BARD) is a system for simulating, detecting and characterizing such releases… read more… might be exposed at a location other than their residence due to mobility. Incorporation of a mobility model in … be exposed at a location other than their resi- dence due to mobility. Incorporation of a mobility model in … by several other researchers [2, 3]. In this paper, we de- scribe a refined version of the BARD simulation al- … -
Estimation And Validation of An Outbreak Simulator
Content Type: Abstract
In previous work, we described a non-disease-specific outbreak simulator for the evaluation of outbreak detection algorithms. This Template-Driven Simulator generates disease patterns using user-defined template functions.… read more… home census block group and time of visit to an emergency de- partment are available for each simulated case. METHODS … mass function. We estimate ( )Sf s by the proportion of all cases that reside in block group s. We estimate the … The Bayesian aerosol release detector. Stat Med 2007. 26(29): 5225-52.

Design of Web-Based Detectability Evaluation Software that Interfaces with a Syndromic Surveillance System
Content Type: Abstract
To design detectability evaluation software that interfaces with the Realtime Outbreak and Disease Surveillance (RODS) System.… for evaluating detectability of seasonal outbreaks due in part to con- straints on historical data that were … The resulting software enables users to conduct de- tectability studies of the RODS system. However, the … -
Identifying Categories of Over-the-Counter Products with Superior Outbreak Detection Performance
Content Type: Abstract
A significant research topic in biosurveillance is how to group individual events—such as single emergency department (ED) visits and sales of over-thecounter healthcare (OTC) products—into counts of “similar” events. For OTC products, the goal is… read more… Data Monitor category that had a high retention rate (i.e., appears in child category 75% or more of time). … of 0.117 (95% CI: 0.113-0.120). The mean timeliness of de- tection of child categories was lower than that of their … -
The Potential of Hospital Data Sources for Influenza Surveillance
Content Type: Abstract
Influenza is an important public health problem associated with considerable morbidity and mortality. A disease traditionally monitored via legally mandated reporting, researchers have identified alternative data sources for… read more… com- munity typically uses for Western Australia.
