The Herald headline and the report is based on estimates derived from an experimental methodology ‘consistent‘ with that used by the ONS.
After a decade and more of pressure from a Tory Government, I’m not sure we can trust the ONS any more. They don’t publish hospital-acquired infections any more and their Covid mortality stats are extremely dubious. See these from late January 2021:
Notice how the death rate from Covid goes up in Wales, Scotland and Northern Ireland after you add those whose death certificate mentioned it to those where there was a positive test? Logical?
How then does it go down for England?
I feel sure I could find more evidence of decay in the ONS, but this should do.
