Tropical microbiologist and coauthor of the 2026 Nature commentary on COVID-19 origins
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 appears verbatim on the UNMC page published 2026-02-25 and is excerpted from the Nature article "COVID’s origins: what we do and don’t know" dated 2026-02-24. However, Nature presents that piece as a multi-author article with 23 named individual authors; Stuart D. Blacksell is listed as one coauthor, not as the sole speaker. Per the single-author verification rule, this quote must be treated as disputed rather than verified as a Stuart D. Blacksell quote. · YouCongress gpt-5.4-2026-03-05 · 1h ago
