ChatterGrabber: A Lightweight Easy to Use Social Media Surveillance Toolkit
Content Type: Abstract
Despite numerous successes in using social media to detect food borne illness and to predict influenza trends, the use of social media as a public health tool has yet to gain widespread adoption. While social media data cannot directly diagnose… read more… illness, aggregate trends in symptom proliferation may readily be observed. Such trends may allow a health agency to watch for signs and symptoms … transfer, and processing of reports. These advantages may enable the earlier preparation and initiation of scaled … -
in silico Surveillance: Informing Surveillance with Simulation
Content Type: Webinar
Simulations of infectious disease spread have increasingly been used to inform public policy for planning and response to outbreaks. As these techniques have increased in sophistication a wider array of uses becomes appropriate.

in silico Surveillance: Using Detailed Computer Simulations to Develop and Evaluate Outbreak Detection
Content Type: Abstract
Developing and evaluating outbreak detection is challenging for many reasons. A central difficulty is that the data the detection algorithms are “trained” on are often relatively short historical samples and thus do not represent the full… read more… Once developed, the same dearth of historical data com- plicates evaluation. In systems where only a count of … digital representa- tions, of every person. These agents visit specific loca- tions throughout the area of study and … in realistic urban social networks.

in silico Surveillance: Highly detailed agent-based models for surveillance system evaluation and design
Content Type: Abstract
Modern public health surveillance systems have great potential for improving public health. However, evaluating the performance of surveillance systems is challenging because examples of baseline disease distribution in the population are limited to… read more… seeking behavior and a surveillance system for outpatient visits.
