I have so many other things that put me at higher risk though...

Me and two siblings inherited it from our father, and the other two siblings have Mom's B+ blood type.

since May 4--chronic intractable (debilitating) migraine headaches, though she never had respiratory symptoms and has long since stopped having fever or other viral symptoms. Her headaches have been severe enough to require an MRI which showed nothing. No migraine drug nor combination has yet been effective and she is miserable a significant percentage of time (though the severity waxes and wanes)

It may well be that blood type protects against severe respiratory disease (O type blood groups appear to have less of the ACE-2 receptor cells that bind virus in their respiratory system) but still susceptible to the more chronic effects that we believe are due to a vasculitis type syndrome.


I too am exposed in the health care setting, but thus far have been more fortunate. I absolutely don't doubt that I am susceptible, though.

I wonder if this could be neutralized to some extent by taking a daily aspirin, as some physicians have informally suggested on SiriusXm Doctor Radio specifically with respect to COVID-19.

The other thing is, other studies have suggested a Vitamin K deficiency could make COVID worse and those doctors recommended people get plenty of dietary Vitamin K or supplement it. But isn't Vitamin K also crucial in the body's ability to form clots? It just seems a bit contradictory. (disclosure: I take supplemental Vitamin K with Vitamin D)

I AM NOT A DOCTOR. Just curious.

almost like the whole choloresterol issue. The body requires some, even the HDL "bad" type, to properly build new cells and maintain old ones. But too much is bad for you.

This is why there are so many ads about blood thinners, used to prevent clotting that leads to strokes and cardiac problems. But overdosing on them leads to induced hemophilia, wherein minor cuts can lead to severe bleeding.

All things in moderation.

BTW, I'm A+ blood type, I've known since my days in the service in the early 70's. It is useful information for health care providers if treatment is needed as it helps them to target treatments that could affected by it.

I take a daily aspirin, and it's my pain killer of choice. I've kind of trained my self to not use anything stronger unless really necessary. As one who is addiction-prone I avoid all kinds of opiods. I also take a daily multi to handle those trace elements I don't get in normal food.

infection risk, which is 66%. So it's actually better to have type A and that's why I've trashed this thread. Too much misinformation overload...

So 30% vs 45 %

If you are 1/3 as likely to do something as Bill, and bill has a 50% chance of doing it...

Standard IQ type question. It’s not the language, it’s your comprehension

"People with type A blood had a 45% risk of becoming infected."

"People with type O were only two-thirds as likely to become infected."

Isn't two-thirds = 66%. So, if the numbers hold, then type O is more likely to become infected. Or do they mean, 2/3 of 45%?

What is two thirds of 45? 30 correct?
That's how I read it.
Your mileage may vary. .

I sucked at word problems.
