1. A method of distributing a saliva simulant, comprising:
receiving the saliva simulant, wherein the saliva simulant comprises water, a DNA taggant, and a carrier, and wherein the saliva simulant simulates human emission of a target pathogen;
spraying the saliva simulant in air at a first release location in a determined release amount, to be detected at a first collection location, wherein a detected amount of the saliva simulant detected at the first collection location relative to the determined release amount is indicative of a degree of airflow from the first release location to the first collection location;
collecting a sample at the first collection location;
determining a tracer concentration at the first collection location based on the detected amount of the saliva simulant detected at the first collection location;
determining a scale that correlates tracer concentrations to inhalation probabilities and/or viral load;
based on the collected amount and/or the tracer concentration, and based on the scale, determining an infection risk value representing infection risk in an enclosed space diagnostic of infection by the target pathogen; and
generating a report displaying a first graphic element representing the infection risk value and displaying a second graphic element representing the detected amount of the saliva simulant at the first collection location in a map comprising the first release location and the first collection location.
