Most of the parameters are about the environment (air-flow, masks, etc.) not about the properties of the specific disease. What would be more useful is a series of comparisons, each with identical environments and only the characteristics of the virus changed (e.g. fix the environment, and compare the spread of COVID-19, influenza, common cold, etc.). This would definitely put the results into layman's terms (e.g. in one environment COVID-19 spreads twice as fast as the other diseases, while in another environment it spreads at half the rate).

@GrahamChiu, yes, I've now added ", especially" to make it less specific.
