We now have the primary diagnosis (PD) update for England. Of those in hospital with COVID, there's been a continuing fall of the % for whom COVID is the PD.
In London the fall is even more marked.
I discuss why this is to be expected here.

It doesn't mean we're not seeing a steep increase in hospital numbers for whom the PD is COVID though. Here's the position for England, with a 30% increase in 3 days from the 25th to 28th (since which overall occupation has risen a further 20%).

And here's the equivalent regional picture, with the sharp increase in London very clear (up 42% in a week)
Again, London has risen a further 15% since the 28th, but we don't have a PD % to match the last two dates with.

Note that some patients where COVID is not the PD will still be in because of it, as explained in the notes here. And the implications for care of those where COVID is an incidental condition are also described.

Finally, you can't simply take a difference of two dates to calculate the primary cause of those admitted between them, as @Mailonline did recently, as I explain here.
Hopefully, its journalists won't make the same mistake with this latest data.
