 The user can set a number of parameters, including room volume, exposure time, activity type, mask-wearing and ventilation.
 The report generated indicates how to avoid exceeding critical concentrations and chains of airborne transmission in spaces such as individual offices, meeting rooms and labs.
 
-The risk assessment tool simulates the airborne spread SARS-CoV-2 virus in a finite volume, assuming a homogenous mixture and a two-stage exhaled jet model, and estimates the risk of COVID-19 infection therein.

 The results DO NOT include the other known modes of SARS-CoV-2 transmission, such as fomite or blood-bound.
 Hence, the output from this model is only valid when the other recommended public health & safety instructions are observed, such as good hand hygiene and other barrier measures.
