BACKGROUND Concern over bio-terrorism has led to recognition that traditional public health surveillance for specific conditions is unlikely to provide timely indication of some disease outbreaks, either naturally occurring or induced by a bioweapon. In non-traditional surveillance, the use of health care resources are monitored in "near real" time for the(More)
BACKGROUND Syndromic surveillance (SS) can potentially contribute to outbreak detection capability by providing timely, novel data sources. One SS challenge is that some syndrome counts vary with season in a manner that is not identical from year to year. Our goal is to evaluate the impact of inconsistent seasonal effects on performance assessments (false(More)
Public health authorities need a surveillance system that is sensitive enough to detect a disease outbreak early to enable a proper response. In order to meet this challenge we have deployed a pilot component-based system in Albuquerque, NM as part of the National Biodefense Initiative (BDI). B-SAFER gathers routinely collected data from healthcare(More)
Currently deployed passive gamma and neutron detectors screen for illicit nuclear material. Archived data can help evaluate special nuclear material detection probabilities and investigate several related issues, including (1) nuisance gamma alarms arising from naturally occurring radiation, (2) the impact of drifting neutron and gamma background rates, and(More)
