People don't understand that there are several real models of cumulative harm that apply to covid infections.

People don't like complex ideas, so they avoid them.

This is going to be a long thread, with several simple ideas that combine to make a big complex one.
First off, we *know* beyond all doubt that covid infections cause short term harm.
The amount of short term harm varies from person to person and infection to infection, but it's there.

Do midwives know that they're now twice as likely to be off sick with a pregnancy related disorder than before the Covid pandemic started? Image
Do nurses?
And health visitors? Image
Similar trend across all staff groups, with an apparent accelerating increase more recently. Image

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.
But it's not the virus that's different, it's the immune system, the metabolism, and the way the body repairs the damage done by the infection.

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 don't want to rewrite that all here, but I don't want to bust the flow of this thread, so at the end of it, I'll post the thread I wrote on linings.

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.
Muscles are fussy about blood flow.
They need a steady supply of oxygen to contract and, crucially, to relax.
Covid messes with the small blood vessels that supply it, so muscles end up slightly under-fuelled, and under-fuelled muscles cramp.

Pfizer.
Do you know which hysterical doom merchants say covid can cause long term lung damage even after a mild case?
British Lung Foundation.
