you mean the symptoms have changed the R naught is between 6-8 the age range for infection has changed (mainly younger people) and it’s 7000 people per day plus in people having a positive test.
But Boris is looking at what is acceptable in deaths. how many people succumbing to covid is ok to sit with the public? after all deaths from normal flu and other infections are rarely front-page tabloid news it has always been known that just the simple task of washing your hands would save millions of lives per year plus the pressure people get in a job when they do have a common cold to go to work, even though the research papers on people taking a sickie when there not sick is far lower in production loss to when someone goes in and spread an illness around the workplace.
edit I look at South Korea and New Zealand's handling of it and then look at the UK and here it's just been a complete car crash for small island nation the amount of death and infection, job losses, miss management u-turns, half-truths, following the science, stupid schemes, buzz words is just gobsmacking punch yourself in the head
