Quote for the day

The genetic sequence of SARS-CoV-2 rules out a lab-engineered virus. And although escape from a lab of a naturally occurring virus that was isolated from bat specimens collected by scientists cannot be completely eliminated as the origin, the closest laboratory version of the virus (published by Shi and collaborators) is separated from SARS-CoV-2 by at least 20 years of evolutionary time.

And that, it seems to me, ought to be that: Covid-19 is a naturally-evolved and –occurring virus.
