The earliest reported COVID-19 cases were associated with Wuhan's Huanan Seafood Wholesale Market [1, 2] , immediately suggesting that SARS-CoV-2 emerged from its mammalian wildlife trade [3, 4] . Subsequent evidence has consistently supported this hypothesis. Spatiotemporal epidemiological data unambiguously distinguished the area near the market as the epicenter of the outbreak [5] [6] [7] [8] . Sequencing of environmental samples placed all known genomic diversity of SARS-CoV-2 at the end of 2019 in a small section of the market [9] . A stone's throw away within the market, a stall was found to contain nucleic acid from both SARS-CoV-2 and animals capable of SARS-CoV-2 transmission [10] [11] [12] . An updated dataset of early SARS-CoV-2 diversity supports a wildlife market origin Z. Hensel & F. D\u00e9barre papers [22] [23] [24] [25] . We added 187 sequences from public databases and new assemblies from public sequencing reads. We identified published studies corresponding to many of the added sequences [26] [27] [28] [29] [30] [31] .

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.

Therefore, HSM has been suspected to be the source of the COVID-19 pandemic (8) . However, the possibility that some individuals outside the market had brought the virus into the market through human-to-human transmission or cold chain could not be ruled out, considering some of the early cases without epidemiological link to the market (7, 9) .
