Abstract

A method and apparatus are provided for performing real-time correlation of data collected from biological sensors, including, but not limited to, sensors adapted to analyze biological material (e.g., blood or tissue samples) and environmental material (e.g., air or water samples). In one embodiment, a method for correlating biological data over a broad (geographic or demographic) domain includes receiving data relating to at least two samples of biological material, where the samples originate at two different regions of the broad domain. This data is then correlated to produce a domain-wide view of the biological data, thereby enabling the rapid identification of domain-wide medical emergencies. Moreover, this correlated information may be provided to lower-level correlation sources or to the biological sensors in order to increase the sensitivities of the correlation sources or biological sensors to emerging threats.
