We also know that the Huanan Seafood Market in Wuhan had a significant role in the early transmission and initial spread of the virus. These animals could have been the intermediate hosts that brought the virus to the market, leading to the early cases in humans.

The clustering of early cases around the Huanan market reflects where the COVID-19 virus emerged, not just where testing looked

Quote authenticity comments

Disputed The quote is authentic and appears verbatim in the cited Nature article; the Nature result snippet reproduces the submitted wording, and the article page is dated 2026-02-24. However, it is not a single-author quote by Masayuki Saijo: Nature lists many individual coauthors on the article, including Saijo, and the piece presents itself as written by 23 of the 27 original SAGO members. Because this platform cannot verify a many-author article as a single-author quote, the attribution to Masayuki Saijo alone is disputed.
