These findings indicate that it is unlikely that SARS-CoV-2 circulated widely in humans prior to November 2019 and define the narrow window between when SARS-CoV-2 first jumped into humans and when the first cases of COVID-19 were reported.

Disputed The sentence is real and appears verbatim in the abstract of the cited paper’s PMC record, but it is not attributable to Alexander Crits-Christoph alone: the paper is a multi-author article (listed as Jonathan E. Pekar, Andrew Magee, Edyth Parker, … Alexander Crits-Christoph, … Joel O. Wertheim / “J. E. Pekar et al.”). Because this platform cannot verify a many-author paper as a single-author quote, the attribution is disputed.
