Particle counts increased what looks like quadratically with power/weight and volume increased linearly with power/weight. The number of virions in these particles was not measured. So I think we have an upper bound of cubic growth, and since the air velocity also increased linearly, information about particle size given air velocity would also be helpful. I imagine that particle size at least goes down with air velocity, so I think more realistically, the increase in number of airborne virions increases somewhere between linearly and quadraticly. >While aerosol particle emission is a major contributor to that risk, it is not the only one, as infection risk also depends on the concentration of the pathogen in the exhaled aerosol particles. So, ideally, others and we would have measured aerosol particle emission and the SARS-CoV-2 titer in aerosol condensates of infected, COVID-19 patients. However, we were unable to perform such an experiment safely. Kind of a bad study, in my opinion. It is not impossible to get in vitro estimates for these quantities and include them in your analysis.
