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] . So\n  [tt:I7XU3gQb0dX2_uDnoN4aWFGld4p0Qa7vgQYdThjUBuY] Surveillance of SARS-CoV-2 at the Huanan Seafood Market.\n    Infections with novel human coronavirus 2019 (HCoV-19) 1,2 , named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by the International Committee on Taxonomy of Viruses (ICTV) 3 , can result in coronavirus disease 2019 (COVID-19), characterized by various clinical outcomes from asymptomatic infections to severe pneumonia and even death 4, 5 . 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. SARS-CoV-2 has high similarity with a few coronaviruses derived from bats in Asian countries in\n  [tt:buS-VjbFvU_GGHRdwTWe7VrhK_eQ2HyhNMEPlJZ2BbE] Identifying zoonotic origin of SARS-CoV-2 by modeling the binding affinity between Spike receptor-binding domain and host ACE2\n    Identification of the direct zoonotic origin (intermediate host) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is important for combating the coronavirus disease 2019 (COVID-19) pandemic [1, 2] . It has become well accepted that SARS-CoV-2 was likely to originate naturally from bats soon after its outbreak, built on the fact that SARS-CoV-2 shares a 96.2% nucleotide sequence identity with the bat coronavirus (CoV) RaTG13 isolated from Rhinolophus affinis [3] and that natural insertions were identified at the S1/S2 cleavage site of the Spike (S) protein of RmYN02-CoV isolated from Rhinolophus malayanus [4] . However, it remains unknown how the related CoV was transmitted from bats to humans. In vitro experiments suggest that RaTG13 also binds to human ACE2 (hACE2) and can use hACE2 as an entry receptor [5] ; thus, it could be possible that a progenitor of SARS-CoV-2, e.g. RaTG13 or RaTG13-like CoV, infected humans and evolved during human-to-human transmission [6] . However, recent experiments show that the binding efficiency of RaTG13 to hACE2 is quite low [7] , probably due to the lack of critical hACE2-binding residues. Besides, no evidence has shown that RaTG13\n  [tt:2hB_6x4Opwdmb8Y5__jNLO8Ykk6JOkXPl8PeR9nZVAk] Surveillance of SARS-CoV-2 in the environment and animal samples of the Huanan Seafood Market\n    Infections with novel human coronavirus 2019 (HCoV-19) (1, 2), named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by International Committee on Taxonomy of Viruses (ICTV) (3) , can result in coronavirus disease 2019 , characterized by various clinical outcomes from asymptomatic infections to severe pneumonia and even death (4) (5) (6) . Globally, as of September 10th 2021, there have been 223,022,538 confirmed cases of COVID-19, including 4,602,882 deaths. No sign hints the pandemic has declined. (covid19.who.int).

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) .
