Interesting. I was not aware that the Blood Type made a difference. Do you have info or a reference for me?
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.
Type a blood type more likely to get corona virus.
