I think one of the most important conclusions people are missing from the data in the recent big studies is that covid infections cause radically diverse long term effects in different age groups.
So much so that it could appear as if they've been infected with different viruses.

Okay folks, I'm calling it, and it's bad news:
The word mucinous is going to become much more common.
Yes, bookmark this tweet, it looks bland, but it's important.
oh, okay. I won't leave you hanging.
I've written a lot recently about how we're missing the big picture of how covid infection is doing cumulative damage to interfaces in the body - linings, membranes, barriers, walls, filters.

I know, I know, you're going to laugh at me for saying that you're more likely to have problems with cramp after you've had a covid infection, but it's all very simple science.
Loads of people have been mentioning cramp recently, and like so many other conditions, yes, covid infection makes it more likely, and makes it worse.
It's just an extra factor on top of all the normal factors for cramp.

Do you know which whacky loons say that covid infections increase the risk of heart disease?
The British Heart Foundation.
Do you know which antivaxers say that covid vaccines do not fully protect against infection, illness, or long term effects?
Pfizer.

A couple of very important studies out just in the last 24 hours confirming what we've been saying for years and years now: Covid infections affect your immune system *badly*.
Here's a few things you may have missed in them.
This is almost entirely post vaccination data
This is not an unprotected population.
Baseline immune measurements come from a period when vaccination coverage was already high, and the immune damage appears *after mass infection*.

You're not going to like the next tweet in this thread, so don't read it.
I don't think there's a difference between the set 'people who have had a covid infection' and 'people who have long term effects from a covid infection'.

This may be obvious to everyone else already, but it occurred to me today that ICE just does not have the manpower to do everywhere what it's doing in Minnesota.
The surge there is not sustainable nationwide.
But the appearance of ICE being everywhere right now is heavily shaped by the unusually large and concentrated deployment in Minnesota, which is drawing outsized attention and resources.

One of my dissertations was on the causes of the second world war.
I wrote it late, in a hurry, when I was young, naive, sleep deprived, and thought that it was ancient history.
But one aspect of what I wrote was what Germany looked like *from the outside*.
🧵
Here are six key views of Germany from other countries at the time that totally misread the situation.
Some of them might be relevant today.

Just imagine for a moment that you are infected with a virus that harms the lining of your arteries. The virus doesn't damage the artery walls in every part of your body to exactly the same degree. Some parts will be more damaged, some less.
At your next infection, will the parts of your artery wall that were more damaged first time round be more or less vulnerable to the virus?
It's an interesting question, isn't it.
Will those damaged parts be better equipped the next time round?

I just want to do a very quick run through the latest up to date charts of rates of sickness absence in *young* doctors here.
Yeah. This is still *really* important, and I'll explain why in a moment.
There are some really really important points before I get on to the graphs.

Let's play "Guess Where The Line Goes"
This one is "Retirement Due To Ill Health, NHS England".
It's a horrible thing to be playing games with, but I think it's less horrible to play 'Guess Where The Line Goes' than to ignore it altogether.
A, B, C, or D?

The minimisers would have you believe that every bad health condition develops immediately, symptoms of it appear immediately, medical attention is found immediately, and the condition is diagnosed immediately.
The truth is very different.
It can take years for conditions to develop after they have been triggered.
I think we've let the damage that covid infections do to *linings* slip into the background of all the other problems that covid infections cause.
I think this may be a *big* problem.
Across all of these, the pattern is the same: structural cell loss is followed by repair that restores structural continuity but not precision of purpose.

It's worth remembering that the UK's end to covid restrictions was built on:
Most kids here never getting vaccinated.
Opening early to get an economic advantage.
Allowing hard intense repeat waves of Covid to rip through.
Getting rid of the weak.
Not much long covid.
Nothing scientific.
Just denial, cruelty, wishful thinking, and greed.

People seem to have forgotten that, in the years before effective HIV treatments existed, many people lived and worked quite normally with HIV for a *long* time. Sometimes close to a decade.
Think of Freddie Mercury, still recording albums.
Magic Johnson, playing elite professional basketball right up until he retired, and only then disclosing his HIV status.

There's something else very important about the @jonstewart video.
"You go 'are you sick' and they say 'I don't want to talk about it'.
When Jon Stewart asks why you're wearing a mask, TALK ABOUT IT.
Say one of these easy things.
Pick one, learn it:
I wear a mask because Covid is airborne.

oh ffs, honestly, how do these people not know that covid infection makes you vulnerable to shingles.
Here's the exact mechanism:
Shingles is your old chickenpox infection (VZV), once sitting dormant in nerve tissue, now waking up when cell-mediated immunity dips.

It feels worth saying that, over the last year, I've seen a growing number of people whose energy, vitality, and enthusiasm are visibly draining month by month.
They're just looking physically and mentally shattered, sliding into a strange exhausted apathy.
In my work, I've always encountered people struggling this way.
