Abstract: A system and method include one or more processors configured to determine a risk index associated with a risk of exposure to a health threat for each node within a chain of nodes during a stage of a journey. The risk index for each node is based on occupancy characteristics of the node, a set of one or more control measures in effect to reduce the risk of exposure in the node, and a health threat prevalence in a jurisdiction associated with the node. The one or more processors are further configured to aggregate the risk indices for the nodes to determine a risk value associated with the stage of the journey, and to generate a control signal to notify a user of the risk value associated with the stage of the journey.

Abstract: Aspects of the disclosure provide solutions for modeling an efficacy of disease screening and testing strategies for an infectious disease. Examples include: identifying events for a disease timeline for the infectious disease, creating a model of test sensitivity as a function of the events, adaptively mapping the events to characteristics of the infectious disease unique to a simulated infected person, based at least on adaptively mapping, creating a unique disease timeline for the simulated infected person, and creating a numerical function specific to the unique disease timeline to model sensitivity as a function of the unique disease timeline.

Abstract: A method and apparatus for detecting an occurrence of an event of interest. The apparatus comprises a surveillance system, a detector, and an analyzer. The surveillance system monitors subjects within an environment to generate monitoring data. The detector detects a number of indicator instances exhibited by at least a portion of the subjects using the monitoring data. Each of the number of indicator instances is an instance of a corresponding event indicator in a set of pre-selected event indicators. The analyzer evaluates the number of indicator instances and additional information to determine whether at least a portion of the number of indicator instances meets an event detection threshold, thereby indicating a detection of an occurrence of an event of interest.
