Comment by Roger Frutos

Virologist and CIRAD researcher who has published on SARS-CoV-2 origins
SARS-CoV-2 was not present in the Mojiang mine making it not possible to be present in any sample. SARS-CoV-2 was never found in samples from the Mojiang mine. [...] Nevertheless, it is simply not possible for a virus which does not physically exist, for a virtual sequence in computer, to escape from a laboratory and trigger an epidemic. [...] There is currently no evidence to support the claim for genetic engineering of SARS-CoV-2. These are only unsubstantiated accusations and a narrative based on a virtual scenario.

Disputed The text itself appears verbatim on the cited PMC article, so as wording it is authentic with ellipses. However, PubMed/PMC identify the source as a multi-author paper by Roger Frutos, Olivier Pliez, Laurent Gavotte, and Christian A. Devaux, not a single-author quote by Roger Frutos alone; the canonical journal citation is Environ Res. 2022 May 1;207:112173 (Epub 2021 Oct 6). Under this platform's rules that makes the stored attribution disputed.
