Which three classic epidemiological characteristics do computer models check in real-time data streams?
Answer
Time, place, and person
The underlying mechanism for anomaly detection in systems like the Pitt ODS relies on applying computational speed to the classic epidemiological triad used for case investigation: time, place, and person. The computer models actively scan the real-time data stream to look for unusual clustering or deviations across these three dimensions simultaneously. For instance, detecting multiple cases of the same illness appearing rapidly (time) in the same ward (place) among patients sharing certain demographic markers or visit types (person) is what prompts the system to raise an alert, moving beyond just raw case counts to spatial and temporal correlation analysis.
