How's that lymph system doing.
Blastic NK-cell lymphoma, England. Image
Blastic NK-cell lymphoma means something has gone *really wrong* in immune regulation.
It’s a malignancy of the cells that are *supposed to destroy infected cells*.
NK cells - "natural killer” cells - are the immune system's first-strike unit.
They're the ones that find and kill virus-infected cells before antibodies even show up.
If you start seeing more NK-cell cancers, something’s driving chronic activation and mutation inside that system.

Something up here. Image
Now, think about Covid infection:
Every infection triggers a massive NK-cell surge.
Those cells get overstimulated, exhausted, and sometimes permanently altered.
Post-COVID studies show lingering activation markers, basically, NK cells stuck in attack mode for months.
That means they keep dividing...
Keep generating oxidative stress...
Keep collecting DNA damage in a high-inflammation environment...
And all that while the repair pathways (like p53) are being suppressed (by cytokines like IL-6 and TNF-alpha).
At the same time, the immune brakes are off.
T cells are depleted and exhausted.
Interferon signalling is blunted.
So when an abnormal clone of NK cells appears, the immune system doesn't clear it. *It lets it grow*.
Add to that the reactivation of latent viruses (EBV, CMV, HHV-6) all known to cause NK/T-cell malignancies...
COVID reawakens them, repeatedly.
Each reactivation wave means another round of inflammation and oxidative stress and immune dysregulation.
The problems aren't just in adults... there's stuff going on in kids too. Image
So you end up with this:
A system of immune cells pushed to divide too often,
mutating in an inflamed environment,
with the tumour-suppressor side of immunity switched off.
And from that, you get what we’re seeing here. A surge in blastic NK-cell lymphoma.
I wonder what else is going on in that lymph system...

Oh boy.
😮 Image
Oh boy. Image
Oh boy oh boy Image
Erm.
👀 Image
👀 Image
👀 Image
👀 Image
And then strange things going on with other aspects of the immune system... Image
And this running away... Image
And then damage to all that lets this kind of damage loose... Image
And that this... Image
Hmm.
Those gut infections are really exploiting something these last four years, aren't they... Image
Oh my word. Image
👀 Image
This is all just nuts. Image
This damage is in adults, kids, infants, everywhere. Image
It's in these kind of diseases where the end result is scarring of internal organs after immune hyperactivation:

This is in KIDS AGED 0 to 9. Image
You might expect this to pop up as a result of immune dysregulation in the gut... Image
Oh boy. Image
What the what. Image
What does inflammation in the brain cause... Image
More tomorrow... this list is long.
Maybe a few more... Image
👀 Image
👀 Image
This is in *kids*
👀 Image
This is in *young adults* 👀 Image
flip. Image
Nothing to see here, just a doubling of TUBERCULOSIS OF BONE. Image
Oh dear. Image
Hmm.
I didn't expect so many people to read this thread, or I would have included a bit like this, explaining that not every condition is rising like that...
@PetersCynthia There's 9,000 charts in the database, it's hard to even view them all, let alone post them!

There are some people who would have you believe that vaccines basically all work the same for different infections, and all have the same effect, but that's not true.

Let me explain this as simply as I can:
Some vaccines are like *insurance*.

You are unlikely to get tetanus, but if you do, vaccination can turn a catastrophic outcome into something far less dangerous. It is protection against a *rare but awful event*.
Some vaccines are like a *firebreak*.

The measles vaccine doesn't just protect the person receiving it. When enough people are vaccinated, measles struggles to find new people to infect, so the whole community is protected, including babies and people who cannot be vaccinated.

Much of the media coverage of worsening health boils down to this:
Gasoline can't have worsened the fire, because the fire had already started.
Covid infections don't have to *cause* a problem to make it *worse*.
If you already have lung cancer, then you catch Covid, your chance of survival drops.

I had one of those really horrible conversations last week with someone who has had a string of new gut and bowel problems in the last year.

Every moment of the conversation a new alarm bell went off.

I came home and checked the charts.
Then I called them and asked if I could post something about it anonymously.
They said yes, so here it is.

The biggest challenge around Covid and Long Covid communication is:

Why doesn't everyone get the same effects.
"Covid can damage blood vessels."
"Covid can affect the brain."
"Covid can disrupt immunity."
"Covid can trigger POTS."
"Covid can cause Long Covid."
People hear that stuff, then they look around and think:

"Well Dave had it twice and he's fine."

See how many of these you recognise:
➡️The biomarkers are inconsistent
👉Long covid is just a collection of vague symptoms
▶️Vaccination changed the risk, so old studies don't apply
♦️Patients are over-attached to biological explanations
➡️The symptoms are real, but that doesn't mean covid caused them
👉There's no unique biomarker for long covid
▶️This is somatisation
♦️Microclots haven't been proven

I've been thinking about this a lot since a woman in our community lost her unborn baby at 32 weeks while ill with a viral infection.

If you look at this chart, it's horribly obvious how much extra suffering viral infections have caused to pregnant women since 2020.

But... Image
But the huge spike in 2020/1, 2021/22, and 2022/3 hides a bigger problem.

That as of the latest data, viral diseases are now causing *three times as many hospital episodes as before Covid came along*. Image
I'm just going to gray those three years out to help you see.. Image
