  • Using cross-correlation networks to identify and visualize patterns in disease transmission

    Content Type: Abstract

    Syndromic surveillance data such as the incidence of influenza-like illness (ILI) is broadly monitored to provide awareness of respiratory disease epidemiology. Diverse algorithms have been employed to find geospatial trends in surveillance data,… read more

  • 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

  • A Novel, Context-Sensitive Approach to Anonymizing Spatial Surveillance Data: Impact on Outbreak Detection

    Content Type: Abstract

    The use of spatially-based methods and algorithms in epidemiology and surveillance presents privacy challenges for researchers and public health agencies. We describe a novel method for anonymizing individuals in public health datasets, by… read more

  • Comparing Telehealth and NACRS Influenza Activity to Fluwatch Surveillance Using EARS-X

    Content Type: Abstract

    This paper will use CDCís EARS-X to examine Tele-healthís potential as an early warning system specifically for influenza-like illness compared to NACRS, as well as qualitatively comparing the resultant EARS flags to peaks in influenza activity… read more

  • A Comparison of Ambulatory Care and Emergency Department Encounters as Data Sources for Detection of Clusters of Lower Gastrointestinal Illness

    Content Type: Abstract

    We sought to compare ambulatory care (AC) and emergency department (ED) data for the detection of clusters of lower gastrointestinal illness, using AC and ED data and AC+ED data combined, from two geographically separate health plans participating… read more
    … For each data stream— AC, ED, and AC+ED combined—repeat visits were omitted if they occurred within 6 weeks of a previous visit to the same setting for LGI. Generalized linear mixed …
  • Clinical decision support at the time of an e-prescription can sustainably decrease unwarranted use of antibiotics for acute respiratory infections

    Content Type: Abstract

    Microorganisms resistant to antibiotics (ABX) increase the mortality, morbidity and costs of infections. In the absence of a drug development pipeline that can keep pace with the emerging resistancemechanisms, these organisms are expected… read more

  • Telephone Triage Data for Detection of Influenza-like Illness

    Content Type: Abstract

    National surveillance is used to detect the emergence and spread of influenza virus variants and to monitor influenza-related morbidity and mortality. Nurse telephone triage (“call”) data may serve as a useful complement to… read more
