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… or locally initiated syndromic surveil- lance for ED visits or 911 calls, sentinel surveillance, ad hoc active … -
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… 2005. These models predict the percentage of total visits from a given date that will be available to the … -

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… questionnaires provided to system operators and site visits. We will develop recommen- dations for system … -
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. … -
