— Professor Michael Levitt (Stanford Professor and Nobel Science Winner)

We can define exponential as f’(t) =k*f(t) but Levitt will insist that if k varies with time, growth is not exponential. 

For COVID19 k decreases from the very first case or death. 

If we take his preprint 'Predicting the Trajectory of Any COVID19 Epidemic From the Best Straight Line'

Then the H(t) in that paper behaves like k in formula above.
