Abstract
Airborne pathogen mobility and the airborne mobility of respiratory droplets, such as saliva, and testing thereof, can be monitored by tracking detectable compounds and measuring concentrations. A display can be presented including a building layout and simulant concentrations released and collected at various locations within a space.
Claims14
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;
- and
- 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.
A method of detecting a pathogen simulant, comprising:
- determining a plurality of locations to receive a saliva simulant released in air, wherein the saliva simulant comprises water, a DNA taggant, and a carrier, the saliva simulant having been determined or characterized to have a behavior suitable for simulating human emission of a target pathogen;
- collecting a sample at each location of the plurality of locations;
- and
- determining an amount of the saliva simulant in the sample.
