The second set are 2nd order polynomial trends - again the USA has been separated out due to the higher raw numbers.

Pretty interesting graphs Russ.
From a model/maths perspective what would we expect to see as the number of infections drop off like in AU and NZ.
From memory, I may be wrong... An exponential decay in maths terms will never cross the zero axis?? so at what stage could we ever say we are free from infection from a modelling perspective?
I'm kind of thinking from a practical perspective we cannot eliminate it as I think I heard a comment that you would need 2 incubation cycles with zero detected infections to have confidence it was gone... And I cannot see that happening
