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… anthrax cases. The home census block group and time of visit to an emergency department are available for each … anthrax cases. The home census block group and time of visit to an emergency de- partment are available for each … (1) For each case, BARD simulates emergency depart- ment visit times using a convolution of two log- normal … -
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… events—such as single emergency department (ED) visits and sales of over-thecounter healthcare (OTC) … clusters OTC products based on how well they ‘explain’ ED visits for influenzalike illness (ILI) can find categories … events—such as single emer- gency department (ED) visits and sales of over-the- counter healthcare (OTC) … -
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… Then we computed the number of cases and the time of ED visit for each case based on the exposure level of a … each release, we measured the change in the number of ED visits per block group produced by the two versions of the …
