Use of syndromic ILI surveillance as a proxy for influenza sentinel surveillance

Salt Lake Valley Health Department (SLVHD) uses syndromic surveillance to monitor influenza-like illness (ILI) activity as part of a comprehensive influenza surveillance program.  During the 2009 spring and fall waves of novel H1N1 influenza, sentinel surveillance became increasingly burdensome for both community clinics and SLVHD.  Given that syndromic surveillance is more efficient and less error-prone, SLVHD evaluated its syndromic surveillance system to determin if  it could be an effective proxy for influenza sentinel surveillance.

The results, shown in a poster that can be accessed here, were overwhelmingly positive, showing a strong correlation between syndromic ILI and sentinel provider ILI cases.

Enhancing Syndromic Surveillance Through Cross-border Data Sharing

The Ohio Department of Health and the Indiana State Department of Health enhanced their individual syndromic efforts through cross-border sharing of emergency department (ED) chief complaint data.

Detection of Enteric Disease Epidemics Using a Diarrhea-specific Category

The Utah Department of Health documented a single epidemic of cryptosporidiosis in Utah during 2007. Seven hundred eleven laboratory-confirmed cases were reported in Salt Lake County, Utah from July 27 through December 18. Illness onset date was available for 86% (611 of 711) of patients and ranged from May 30 through November 11. Approximately 32% (224 of 691) of patients sought care in area emergency departments or urgent care facilities, and 8.5% (50 of 590 with data available) of patients required hospitalization.

Preferences & Perceptions of Biosurveillance System Users

Early detection is a function of many biosurveillance systems that strives to decrease the time between the onset of an event (e.g. infectious disease epidemic) and discovery. Situational awareness is another function that provides for timely information that public health can use to assess status of events (e.g. outbreak progression or general community health). With 1 being "No Importance" and 5 being "Most Important", please rate each of these functions as they relate to your desires. (65 respondents)

Evaluation of Microbiology Orders from a Veterinary Diagnostic Laboratory as a Potential Data Source for Early Outbreak Detection

Animals continue to be recognized as a potential source of surveillance data for detecting emerging infectious diseases, bioterrorism preparedness, pandemic influenza preparedness, and detection of other zoonotic diseases.  Dr. Loren Shaffer explores this issue in a paper published by Advances in Disease Surveillance and can be accessed from their website.
