Using Open-Source Grid-Computing Technology to Improve Processing Time for Geospatial Syndromic Surveillance Data
Content Type: Abstract
Outbreak detection algorithms for syndromic surveillance data are becoming increasingly complex. Initial algorithms focused on temporal data but newer methods incorporate geospatial dimensions. As methods evolve, it is important to understand the… read more… consist of 2 clusters, each containing 204 nodes. All computational nodes have two 2.4 GHz Pentium 4 Xeon … recorded. RESULTS Processing serially, as is typical in a PC environment, can be an inefficient way to handle large … -
Privacy Protection versus Cluster Detection in Spatial Epidemiology
Content Type: Abstract
With the widespread deployment of near real time population health monitoring, there is increasing focus on spatial cluster detection for identifying disease outbreaks. These spatial epidemiologic methods rely on knowledge of patient location to… read more… subsequent spatial analyses.

State Surveillance Data Improves a Clinical Prediction Model for Pertussis
Content Type: Abstract
Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous for young infants. Pertussis is difficult to diagnose, especially in its early stages, and definitive test results are not… read more… Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous … Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous for … date exceeded 0.09 (13% sensitive, 53% specific, PPV 26%, NPV 94%, AROC 0.65).
