Comment by Abdullah Assiri

Human avatar
Public-health official 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 quote is real and appears verbatim on the cited UNMC page, which reproduces the sentence pair exactly, and the underlying Nature Comment is dated 2026-02-24. However, Nature lists 23 individual co-authors for the article, with Abdullah Assiri as only one of them, so this is not verifiable here as a single-author quote attributed solely to him.
