Claim 21:
22. An epidemiology transmission probability analysis device comprising:
at least one electronic processor;
at least one display operatively connected with the electronic processor; and
at least one non-transitory storage medium storing a medical facility floor map and instructions readable and executable by the at least one electronic processor to perform operations including:
selecting a number of ray origin points in response to a statistical occupancy of a medical facility floor map, a communicability of a specific disease being mapped, or a size of an infectious zone of the specific disease being mapped;
selecting cast rays in response to the number of ray origin points generated, the cast rays stopping upon encountering a physical barrier mapped in the medical facility floor map;
receiving via a user input operatively connected with the one or more electronic processors, wherein the user input defines a porous barrier in the medical facility floor map, the cast rays further stopping upon encountering the porous barrier with a stopping probability indicative of porosity of the porous barrier;
generating an infectious transmission probability map from intersections of the cast rays, wherein the transmission probability map is generated from densities of intersections of the cast rays over the medical facility floor map, the densities incorporating the porosity of the porous physical barrier;
computing an infectious transmission probability for a space or transport route of the medical facility floor map by aggregating the spatially dependent infectious transmission probability given by the infectious transmission probability map over the space or transport route; and
controlling the at least one display to present at least a portion of the medical facility floor map overlaid with a graphic representing the space or transport route with the graphic labeled with the computed infectious transmission probability for a space or transport route.
