> [T]he findings suggest that people with blood type A face a 50 percent greater risk of needing oxygen support or a ventilator should they become infected with the novel coronavirus. In contrast, people with blood type O appear to have about a 50 percent reduced risk of severe COVID-19.

The prior part of the paragraph that you didn’t copy pasta was critical in understanding context here. The study didn’t look at blood types directly, but looked at genes which express as those two blood types, finding that the genes correlate with supplemental oxygen need during severe symptoms.

  A blood type test is easier, faster and cheaper for a hospital to do than a genetic sequencing.

  IIUC, you're saying that the genetic markers in question correlate perfectly with blood type. If so, then why would it matter whether the comment framed the issue in terms of blood type vs. those genes?
- dnautics 6y ago
  Blood type phenotype correlates nearly exactly one to one with their synthesis gene genotype, so this semantic distinction is not very important.
- sudosysgen 6y ago
  Since those genes are 99.9% accurate predictors of blood type, I think that's a distinction without a difference.

  Can you please elaborate on the caveat, I don't follow.

      That is really interesting, thanks for replying!

  I wonder if it's actually related. More exposure to blood born viruses => better immunity to some class of viruses.
