A Zero-Inflated Poisson Based Spatial Scan Statistic
Content Type: Abstract
The spatial scan statistic proposed by Kulldorff has been widely used in spatial disease surveillance and other spatial cluster detection applications. In one of its versions, such scan statistic was developed for inhomogeneous Poisson process… read more -

Public health officials and epidemiologists have been attempting to eradicate syphilis for decades, but national incidence rates are again on the rise. It has been suggested that the syphilis epidemic in the US is a "rare example of unforced,… read more -
A new interpretation of the inference test for the spatial scan statistic
Content Type: Abstract
Spatial cluster analysis is considered an important technique for the elucidation of disease causes and epidemiological surveillance. Kulldorff's spatial scan statistic, defined as a likelihood ratio, is the usual measure of the strength of… read more -
Confusing Standards: Common Misconceptions about Disease Surveillance Standards
Content Type: Abstract
Domains go through phases of existence, and the electronic disease surveillance domain is no different. This domain has gone from an experimental phase, where initial prototyping and research tried to define what was possible, to a utility phase… read more -
Sufficient reduction methods for multivariate surveillance
Content Type: Abstract
Parallel surveillance, separate monitoring of each continuous series, has been widely used for multivariate surveillance, however, it has severe limitations. Firstly, it faces the problem of multiplicity from multiple testing. Also, the ignorance of… read more -
Impact of training on Disease Surveillance and Notification Officers in Nigeria
Content Type: Abstract
Public health surveillance (also called field epidemiology) as defined by Centres for Disease Control and Prevention (CDC) is the ongoing systematic, collection, analysis, and interpretation of outcome specific data essential to the planning ,… read more -
Subsidized laboratory testing as an incentive for improved livestock disease reporting
Content Type: Abstract
Livestock owners normally pay the full cost of disease testing. As a result the number of laboratory submissions is dependent on the owner's perception that testing is beneficial. This decreases the likelihood of an accurate diagnosis and biases the… read more -
Emergency Department Patients with Gastrointestinal Symptoms During Federal Holidays, Miami-Dade 2007-2010
