  • Preliminary Findings from the BioSense Evaluation Project

    Content Type: Abstract

    In October 2006, the Centers for Disease Control and Prevention funded four institutions, including Emory University, to conduct evaluations of the BioSense surveillance system. These evaluations include investigations of situations… read more

  • Improving Detection Timeliness by Modeling and Correcting for Data Availability Delays

    Content Type: Abstract

    The performance of even the most advanced syndromic surveillance systems can be undermined if the monitored data is delayed before it arrives into the system.  In such cases, an outbreak may be detected only after it is too late for appropriate… read more

  • Active Fever Surveillance During Malaria Outbreak in Western Jamaica

    Content Type: Abstract

    Malaria, major leading cause of morbidity and mortality in third world countries has been successfully eliminated from Jamaica since 1965. This, however, is being constantly challenged by lack of sustained vector control… read more

  • The Predictive Accuracy of Non-Regression Data Analysis Methods

    Content Type: Abstract

    Analysis of time series data requires accurate calculation of a predicted value. Non-regression methods such as the Early Aberration Reporting System CuSum are computationally simple, but most do not adjust for day of week… 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

  • Linking Public Health and Healthcare Data for Syndromic Surveillance

    Content Type: Abstract

    A number of syndromic surveillance systems include tools that quickly identify potentially large disease outbreak events. However, the high falsepositive rate continues to be a problem in all of these systems. Our earlier work… read more
    … in the patient encounter dataset, same day office visits corresponded well with the flu epidemic curve. …
  • Methodology for prediction of outbreaks of diseases of military importance

    Content Type: Abstract

    Traditional public health practice has relied on public health surveillance of disease to detect outbreaks in an effort to mitigate their effects. Often the earlier an outbreak is detected, the greater the mitigation of its effects. The logical… read more

  • Non-parametric intensity bounds for the visualization of disease clusters

    Content Type: Abstract

    Consider the most likely disease cluster produced by any given method, like SaTScan,  for the detection and inference of spatial clusters in a map divided into areas; if this cluster is found to be statistically significant, what could be… read more
