Blood Group linked to Covid risk?

[likeamillpond]

Ive seen a few articles recently British and American, saying that certain blood groups, especially A and AB being more at risk of serious illness if they contract covid than those who are type O.
I'd heard of other risk factors e.g. age, weight,
But this I never knew!
How come we don't hear more of this.

Any links to the articles?

Britain's one of the few countries where people don't know tbeir own blood group,
unless you're a blood donor or specifically ask for it in hospital .

Any links to the articles?

I tried to do one, phone playing up today www.hematology.org/newsroom/press-releases/2020/possible-link-between-blood-type-and-covid-19

There was some noise about this last year, I remember. I imagine it hasn't been mentioned much because there's nothing you can do about it. I don't think the differences are significant enough to mean that you should shield if you are AB but not if you are O for example. It's only really of relevance from a scientific perspective, understanding how the virus works and so on, at least that was the impression I got from reading about it in 2020.

I think I ve' seen it somewhere while back, but didn't think anything of it. In my native country, most common blood type is A. If this is true, then they should be getting far more seriously ill and dead people.

There are links between blood groups and auto immune illness like diabetes so it's probably hard to untangle

This has been known far months, I remember reading about it ages ago but what can you do with the info really? You can't change your blood type and I don't remember the difference being large enough to change behaviour

I have known about this for months. The difference between blood groups is small. It is not a major factor, like age or BMI. Not significant enough to affect vaccine priority.

For anyone interested in this - countries and blood group data:

I only know my blood group as it was on my pregnancy notes. Most people wouldn't have a clue.

blood group alone is not enough for the picture, this article perhaps explains a bit more clearly findings so far. www.ed.ac.uk/igmm/news-and-events/news-2021/genes-could-be-key-to-new-covid-19-treatments

I read about this last year, I can't remember where, I think they even mentioned it on the BBC news, and then all information stopped. I would have liked to have read some peer reviewed research, but maybe there wasn't any?

It's interesting because out of all our family, I had COVID badly and so did one of my adult children. We both have blood group A whereas everyone else is group O. But we're obviously such a small sample, I would like to understand more....

I think it was inconclusive in the end?

I had heard of this - I'm a blood donor, so know my group (A). But there's nothing I can do about it, is there?

Maybe they were told go stop reporting it in case Type Os used it as an excuse to flout the rules Although as I said, unless you're a blood donor, most people in the UK have absolutely no idea which blood group they belong to.

That's very interesting.
The Economist is also running a story on it.

I meant this is what Economist has a story on.

I think it's very interesting and have been following it too. I was worried as I'm one of the more 'at risk' blood groups but had mild Covid in the end so not sure what that means.

I read about this last year. I'm O negative.

Well that's good news -- DH is O- & gets every respiratory bug badly. Would be nice if he didn't get bad covid.

I'm AB+ but convinced I'm tough as nails, so have zero fear of covid. I never get bad respiratory bugs. DH is also supposed to be susceptible to norovirus & I'm supposed to be resistant. Reality is opposite. I get pukey bugs very easily & he almost never gets any.

I’m O+ & while I didn’t need hospitalisation, I was very poorly with Covid & now have long Covid (currently 10 months in).

It’s very interesting. Nobody else in my household knows their blood group - DH, DS1, DS2 nor DD. I’m the only one of us to become ill with it. I was also severely Vitamin D deficient (level of 11) just prior to catching Covid & that has also been linked to people suffering more severely.
