1. A method of testing and evaluating a building space for possible airborne pathogen travel, the method comprising:
releasing a simulant at a first release location within the building space, wherein the simulant comprises water, a DNA taggant, and a carrier, and wherein the simulant is characterized in having a behavior suitable for simulating human emission of a pathogen;
collecting a portion of released simulant at a first collection location within the building space, wherein the first release location and the first collection location are separated by building infrastructure of the building space and wherein the first release location and the first collection location are such that measurable airflow occurs from the first release location to the first collection location; and
displaying movement of the simulant, comprising:
(a) receiving information of a first amount of the simulant at the first release location and of a second amount of the simulant detected the first collection location; and
(b) generating a report displaying a first graphic element representing the first amount of the simulant at the first release location and displaying a second graphic element representing the second amount of the simulant at the first collection location in a map comprising the first release location and the first collection location.
