In the 78-page document, we determined that most of the peer-reviewed scientific evidence supports the hypothesis that SARS-CoV-2 has a zoonotic origin, meaning that it came from an animal.

Disputed The quote text is real and appears verbatim on the UNMC page, which was published on Feb. 25, 2026, but that page presents it as a reprinted Nature piece written collectively (“We are 23 of the 27 original members...”), not as a statement by Marietjie Venter alone. Nature’s byline lists Marietjie Venter plus many coauthors, so this platform cannot verify it as a single-author quote by her.
