Patent ID: 7266484

Claim:
A system for early detection of localized exposure to an agent active on a human population, comprising: a processor; and a computer readable medium carrying one or more sequences of instructions which, when executed by the processor, cause the processor to carry out the steps of: collecting, for each data type of a plurality of different data types relevant for detecting exposure to the agent, a plurality of time series of data at a corresponding plurality of locations associated with the data type, wherein each different data type is an indicator of human population health that may be affected by exposure to the agent; generating measures of anomalous conditions of human population health, each indicative of the localized exposure to the agent, at the plurality of locations for each of the plurality of different data types based on the plurality of time series and a temporal model for each data type; performing cluster analysis on the measures of anomalous conditions to determine an estimated location and estimated spatial size of effects from the agent around the estimated location; generating a replica of anomalous conditions, resulting from a hypothetical exposure to the agent, for a particular location within the estimated spatial size of effects determined during said step of performing cluster analysis by modeling a hypothetical exposure event that is based on at least one of the estimated location and the spatial size of the effects determined during said step of performing cluster analysis; matching the replica to the measures of anomalous conditions for the particular location to determine whether the measures of anomalous conditions indicate an actual exposure event similar to the hypothetical exposure event; producing at least one of a modified estimated location and a modified estimated spatial size or effects from the agent based on a result of said step of matching the replica; generating a modified replica of anomalous conditions for a second particular location within the modified estimated spatial size by modeling a modified hypothetical exposure event that is based on at least one of the modified estimated location and the modified spatial size of the effects; matching the replica to the measures of anomalous conditions for the second particular location to determine whether the measures of anomalous conditions indicate an actual exposure event similar to the modified hypothetical exposure event; and if it is determined an actual exposure event has occurred, then sending, via a computer interface, an alert signal that indicates a likely time, a likely location and a spatial size of the actual exposure.
