I've seen some comments stating that during the peak we were detecting less than 10% of Covid cases, but now we're more like 60-75% ...
Which means our current rate of cases (adjusted) is roughly the same as when full lockdown was announced
/1
20 March - 413 cases (7 day avg)
413 x (100/10%) = 4,130 cases

12 September - 3,001 cases (7 day avg)
3,001 x (100/65%) = 4,616 cases

Well, roughly. I'm no statistician. I'm just exercising my "British common sense". Anyway...

But daily deaths are not comparable

Reasons I've heard
-Cases mostly younger people who don't get so ill (28% are 20-29 age group)
-NHS early treatment better
-Many vulnerable people died already
-Social distancing observed by vulnerable
-Vast under-recording of peak cases

Another reason that's out there...

-The virus mutates and has become less dangerous.

"a steady trickle of immune-evading mutations could help SARS-CoV-2 to establish itself permanently... potentially causing mostly mild symptoms"

This may well explain why Spain & France, who are considerably ahead of our curve in new cases, whilst having some uptick in deaths, are not seeing the death rates anywhere near March/April levels.

If so, that's great news. But the jury is still out of course.
