  • Data-Adaptive Multivariate Control Charts for Routine Health Monitoring

    Content Type: Abstract

    This paper investigates the use of data-adaptive multivariate statistical process control (MSPC) charts for outbreak detection using real-world syndromic data. The widely used EARS [1] methods and other adaptive implementations assume implicitly… read more

  • Evaluating Pandemic Influenza Surveillance and Response Systems in Developing Countries: Framework and Pilot Application

    Content Type: Abstract

    A pandemic caused by influenza A/H5N1 or another novel strain could kill millions of people and devastate economies worldwide. Recent computer simulations suggest that an emerging influenza pandemic might be contained in Southeast Asia through rapid… read more

  • Use of Severity Indicators in a Public Health Surveillance System

    Content Type: Abstract

    Data streams related to case severity have been added to the Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE), a disease-monitoring application used by the Department of Defense (DoD), as an additional… read more

  • Cross Disciplinary Consultancy: Negation Detection Use Case

    Content Type: Abstract

    Despite considerable effort since the turn of the century to develop Natural Language Processing (NLP) methods and tools for detecting negated terms in chief complaints, few standardised methods have emerged. Those methods that have emerged (e.g.… read more

  • An ISDS-Based Initiative for Conventions for Biosurveillance Data Analysis Methods

    Content Type: Abstract

    Twelve years into the 21st century, after publication of hundreds of articles and establishment of numerous biosurveillance systems worldwide, there is no agreement among the disease surveillance community on most effective technical methods for… read more

  • The Development of Virtual Data for Syndromic Surveillance Exercises

    Content Type: Abstract

    On 27 April 2005, a simulated bioterrorist event—the aerosolized release of Francisella tularensis in the men’s room of luxury box seats at a sports stadium—was used to exercise the disease surveillance capability of the National Capital Region (NCR… read more
