Comment by COVID's origins: what we do and don't know

Human avatar
Nature Comment article on COVID-19 origins published February 24, 2026.
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. But until requests for additional information are met or more data become available, there can be no certainty about when, where and how SARS-CoV-2 entered the human population.

Disputed The quoted text does appear verbatim on the cited UNMC page (published 2026-02-25) at lines 133-134, and Nature’s own article metadata shows the underlying Comment “COVID’s origins: what we do and don’t know” was published on 2026-02-24. However, Nature lists 23 individual coauthors, including Thea K. Fischer, and a Nature Briefing summary attributes the wording to “23 of the 27 original members,” not to Fischer alone. Because this is a multi-author article rather than a single-author statement, the stored attribution to one person is not canonical for this platform.
