In particular, [the U.S. Centers for Disease Control reports that](https://archive.is/nnWT9) black Americans are 4.7 times more likely than whites to be hospitalized, and 2.1 times as likely to die. [Sigal Samuel of _Vox_'s "Future Perfect" section writes](https://www.vox.com/future-perfect/2020/10/2/21493933/covid-19-vaccine-black-latino-priority-access): + +> There's nothing about being Black, in and of itself, that makes people more biologically susceptible to Covid-19. Instead, the disproportionate impact is due to an accumulation of factors from centuries of systemic racism. + +But how does Samuel _know_ this? I agree that an accumulation of factors from centuries of systemic racism is almost certainly going to be a significant _part_ the explanation for ethnic differences. But the claim that "there's _nothing_ about being Black, in and of itself" (emphasis mine) affecting susceptibility to this disease is a _much_ stronger assertion, one that I think has a substantial probability of being false, if it turns out that one of the various minor ways in which humans vary by genetic ancestry happens to be relevant to the progression of this particular disease. + +I remember back in February-ish there was a claim being floated around that Asians might be more susceptible to COVID-19 due to differences in [angiotensin-converting enzyme 2](https://en.wikipedia.org/wiki/Angiotensin-converting_enzyme_2) activity. So, I don't think that panned out, and I'm sure many people with domain expertise who [actually read the paper](https://www.biorxiv.org/content/10.1101/2020.01.26.919985v1.full) called it. (Seriously, _n_=8?!)
