I had read some of this in preprint, so it has been a while.  Today, while reading another article from some media outlet (ie, non-medical), I saw a headline link that claimed blood type influenced getting the disease.  That didn't fit what I remembered.

The media article's link was to this paper.  It is confusing, but I still read the paper as indicating the blood type association was to patients with severe COVID-19 with respiratory failure, not to simply COVID-19.

Am I confused?  Is the blood type association to getting the disease, or to respiratory failure if you have the disease?


By the way, I thought this was an informative video (mostly about testing).  Specifically, I wanted to point out this graphic (at 1:00) that respiratory failure is only one of several phases of COVID-19.  

• presymptomatic phase:  1-3 days before onset of symptoms
  
• viral phase: 0-14 days after onset of symptoms
  
• cytokine storm phase: 7-15 days after onset of symptoms
  
• coagulation phase: 13-22 days after onset of symptoms
  
• late hyperinflammatory phase: 18-33 days after onset of symptoms
  

I haven't seen that graphic elsewhere.

In regards to this post, I believe the blood group association has not yet been shown to apply to the other phases.  I'd guess they were all related, but maybe not.
