This paper adds another layer to the accumulating evidence that all points to the same scenario: that infected animals were introduced into the market in mid- to late November 2019, which sparked the pandemic.

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

Statement relation comments

AI Verified Relevant: the quote explicitly says infected animals were introduced into the Huanan market and that this 'sparked the pandemic,' which directly addresses whether the market-centered clustering reflects the virus's emergence location. In the same source, the article says the results imply very few, if any, human infections before the market outbreak and that the sequences are consistent with 'market emergence,' so one stance on the complete statement is substantially more likely.

AI Verified He says infected animals were introduced into the Huanan market in mid- to late November 2019 and that this sparked the pandemic. In context, the article also presents the data as consistent with a market emergence and says there were very few, if any, infections before the market outbreak, so the implied position is that the early case clustering around the market reflects the origin there rather than merely where investigators looked.
