I keep wondering what unintended consequences our nearly-unprecedented efforts on non-pharmaceutical interventions ("lockdown", social distancing, masks, etc.) might end up having on the virus - for example, could all our isolation and distancing be accidentally selecting for strains of the virus that transmit more readily over further distances?

The mitigations are effective in slowing the spread (to varying degrees, due to a multitude of factors), which in turn slow down the rate of mutation. In any case, I would expect the dispersion of the virus to follow a pattern similar to https://www.youtube.com/watch?v=plVk4NVIUh8

Don't know about your country/region but here the mitigations are put in effect because hospitals can't handle the pressure anymore.

That will be a tough one to measure.

However measurement of the impact of lock-downs/social distancing upon existing known virus's like colds and flu's would give an insight into that whole area.
