  • Natural Language Processing and Technical Challenges of Influenza-Like Illness Surveillance

    Content Type: Abstract

    Processing free-text clinical information in an electronic medical record (EMR) may enhance surveillance systems for early identification of ILI outbreaks. However, processing clinical text using NLP poses a challenge in preserving the semantics of… read more

  • Kidenga: Public engagement for detection and prevention of Aedes -borne viral diseases

    Content Type: Abstract

    Zika, chikungunya, and dengue have surged in the Americas over the past several years and pose serious health threats in regions of the U.S. where Ae. aegypti and Ae. albopictus mosquito vectors occur. Ae. aegypti have been detected up to 6 months… read more

  • Evaluating the Utility of HealthMap as a Supplementary Surveillance Tool

    Content Type: Abstract

    HealthMap collects and aggregates information from online sources to generate outbreak alerts based on disease and geographic location. This project will assess the timeliness and sensitivity of HealthMap based on outbreak posts from EpiCom, the… read more

  • Searching for Complex Patterns Using Disjunctive Anomaly Detection

    Content Type: Abstract

    Modern biosurveillance data contains thousands of unique time series defined across various categorical dimensions (zipcode, age groups, hospitals). Many algorithms are overly specific (tracking each time series independently would often miss early… read more

  • An Experimental Fully Automatic Syndromic Surveillance in Japan

    Content Type: Abstract

    Since we donít know when such a disaster may occur, we have to perform this syndromic surveillance routinely, and thus the system should be automatic. Namely, information is drawn from electronic medical records (EMR), and is statistical analyzed,… read more

  • Enhanced Influenza Surveillance using Telephone Triage Data in the VA ESSENCE Biosurveillance System

    Content Type: Abstract

    Telephone triage is a relatively new data source available to biosurveillance systems.1-2Because early detection and warning is a high priority, many biosurveillance systems have begun to collect and analyze data from non-traditional sources [… read more

  • Evaluating a Social Network Analytic Tool to Support Outbreak Management and Contact Tracing in an Outbreak of Pertussis

    Content Type: Abstract

    Pertussis (i.e., whooping cough) is on the rise in the US. To implement effective prevention and treatment strategies, it is critical to conduct timely contact tracing and evaluate people who may have come into contact with an infected person. We… read more
