CONTACT TRACING OF EPIDEMIC-INFECTED AND IDENTIFICATION OF ASYMPTOMATIC CARRIERS

摘要

A method for contact tracing of a carrier of infection within a population identifies the carrier of the infection and acquires recorded tracking information that shows geographical location and timing for each of a plurality of members of the population within a predetermined time period. From the acquired tracking information, at least a first geographic location visited by the carrier and a corresponding first time interval for the carrier visit are identified and at least a second individual determined to have been present at the first visited geographical location for a second time interval that at least partially overlaps the first time interval is identified. A corresponding infection risk value for the second individual is calculated. A first signal having message content that alerts the second individual to the calculated infection risk value is transmitted. The transmitted message content displays on a personal communications device associated with the second individual.
