No, but they are studying it. Next time you talk to your neighbors you might ask.
The stories/studies mention Type A more susceptible ..type O less susceptible..no mention of B
and there may have been a group with O that was even less at risk..positive or negative RH factor..dont remember.
Clearly there was something about the Wife that kept it from taking hold of her. Blood Type, Genes, etc.
He has type B and she has Type A.
It is a weird virus. His Oxygen saturation was quite low - around 84% by pulse oxymeter but he wasn’t struggling to breathe. He insisted on using his CPAP machine in the ICU and he made a good recovery without being intubated. And was discharged from ICU to home after 5 days. OxSat back to mid 90s. (Never smoked. )
The thyroid gland greatly influences a person’s immune system.
My daughter (56) was diagnosed about 10 years ago with Hashimoto’s Disease and has been unable to work. She has to take about 20 Rx and vitamins per day, but may still be bedridden 2-3 days in a row and suffers from insomnia.
It’s caused by a thyroid problem, which severely weakens the immunity system. She’s a prime candidate for the C-virus, but I met her for lunch a couple of weeks ago and she’s fine.
I’m 77 (O+ blood), no underlying health problems and have had no symptoms. I go to the grocery store about every 4-5 days and usually sleep about 10-12 hours a day (I’m a night owl). Sleep really helps your immune system work.
I don’t know anyone from a large group of my friends who has tested positive for C-v.
