HEALTH SURVEILLANCE CAN BE VIEWED AS AN ONGOING SYSTEMATIC COLLECTION, ANALYSIS, AND INTERPRETATION OF DATA FOR USE IN PLANNING, IMPLEMENTATION, AND EVALUATION OF A GIVEN HEALTH SYSTEM, IN POTENTIALLY MULTIPLE SPHERES (EX: animal, human, environment). As we move into a sophisticated technologically advanced era, there is a need for cost-effective and efficient health surveillance methods and sy...

The problem of optimizing sentinel surveillance in networks is to find the nodes where an emerging disease outbreak can be discovered early or reliably. Whether the emphasis should be on early or reliable detection depends on the scenario in question. We investigate three objective measures quantifying the performance of nodes in sentinel surveillance—the time to detection or extinction, the ti...

Methods As part of a large community study, subjects older than 2 years reporting at least two symptoms of influenzalike-illness were recruited from 30 outpatient clinics in Hong Kong prospectively from February 2007 to July 2010 around the influenza seasons [1,2]. Each subject provided a pooled pair of nose and throat swabs to be tested by the QuickVue rapid test on site. Overall test positive...

To clarify the epidemiology of influenza A viruses in coordinated swine production systems to which no animals from outside the system are introduced, we conducted virologic surveillance during September 2012-September 2013. Animal age, geographic location, and farm type were found to affect the prevalence of these viruses.

Cell invasion through basement membrane (BM) is a specialized cellular behavior critical to many normal developmental events, immune surveillance, and cancer metastasis. A highly dynamic process, cell invasion involves a complex interplay between cell-intrinsic elements that promote the invasive phenotype, and cell-cell and cell-BM interactions that regulate the timing and targeting of BM trans...

This paper provides a review of the past, present, and future of public health surveillance-the ongoing systematic collection, analysis, interpretation, and dissemination of health data for the planning, implementation, and evaluation of public health action. Public health surveillance dates back to the first recorded epidemic in 3180 B.C. in Egypt. Hippocrates (460 B.C.-370 B.C.) coined the te...
