Globally, as of Feb 28 th 2023, over 758 million confirmed cases and over 6.8 million deaths have been reported (covid19.who.int). Human cases with COVID-19 were first reported in late December 2019, in Wuhan, China, as pneumonia of unknown etiology (PUE). A majority of these early cases were found to be linked to the Huanan Seafood Market (HSM) in Wuhan 4, 6 , where various animal meats, exotic seafood and live animals were available for purchase. The HSM has been suspected to be the source of the COVID-19 pandemic 7 . Not all of the early human cases had epidemiological links to the market 6, 8 and alternative hypotheses for the market association, for example entry of virus into the market via humans or the cold-chain, also exist.

Worobey <i>et al</i>.\n    It has been brought to the authors' attention that two files in the GitHub repository associated with the paper were identical: \"distance_popdensityagegroups_null_35.csv\" (located at https://github.com/ sars-cov-2-origins/huanan-market/tree/main/data) and \"distance_popdensityagegroups_null_120.csv\" (located at http://doi.org/10.5281/zenodo.6786454 ). These files included median distances to the Huanan market of locations drawn from a Wuhan population density map, as described in the paper. In the original GitHub submission, the data in \"distance_popdensityagegroups_null_35.csv\" were incorrect. The median values in that file were duplicates of those in \"distance_popdensityagegroups_null_120. csv.\" Upon inspection of these files, the authors also noticed that the number of pseudoreplicates contained in these two files and in one additional file (\"distance_popdensityagegroups_null_155.csv\") was 10,000 rather than the n = 1000 used for all related analyses. The authors therefore generated new versions of these three files with n = 1000 and reran all statistical tests in which any of the three files were used.
