Although treatment has definitely improved outcomes, IMO, at least some of this effect has to be due to the changing demographics of testing. In the early days patients essentially had to be far along in the progress of the disease to be tested, we simply had very little testing capacity. Now we are doing many times more tests against a much wider set of subjects. So it is inevitable that we are getting more of the milder cases and cases earlier in their development. This also accounts for the so-called “shift” toward many more young patients. The disease hasn’t changed. Current testing is sampling a different distribution of patients than previous months had been.
