Comparison of Aberration Detection Algorithms for Biosurveillance Systems
Content Type: Abstract
Use of robust and broadly applicable statistical alerting methods is essential for a public health Biosurveillance system. We compared several algorithms related to the Early Aberration Reporting System C2 (adaptive control chart) method for… read more… effects and the total daily volume of facility visits. Adjustment for the total visit volume allows monitoring of surrogate rates instead of … to compare different ways of adjusting for total facility visits and background day-of-week effects.

Enhanced Influenza Surveillance using Telephone Triage Data in the VA ESSENCE Biosurveillance System
Content Type: Abstract
Telephone triage is a relatively new data source available to biosurveillance systems.1-2Because early detection and warning is a high priority, many biosurveillance systems have begun to collect and analyze data from non-traditional sources [… read more… searches (e.g. Google Flu Trends) and TT]. These sources may provide disease activity alerts earlier than … searches (e.g. Google Flu Trends) and TT]. These sources may provide disease activity alerts earlier than …
