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). Early human cases with COVID-19 were first reported in late December 2019 from Wuhan, China with pneumonia of unknown etiology (PUE), and a majority of them were found to be linked to Huanan Seafood Market (HSM) in Wuhan (6, 7) , where various animal meats and exotic seafoods were available for purchase. 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) .

Since its emergence, numerous animal species have been studied to identify possible reservoirs and/or intermediate hosts of the virus, including a large diversity of insectivorous bats of the genus Rhinolophus. Despite the recent report of various SARS-CoV-2-related viruses in Rhinolophus shameli (isolated in Cambodia in 2010 1 ), R. pusillus and R. malayanus (China, 2020 and 2019 respectively 2 ), in R. acuminatus (Thailand, 2020 3 ) and R. cornutus (Japan, 2013 4 ), the closest SARS-CoV-2 bat-borne genome still remains the one from R. a nis, RaTG13 (China, 2013) 5, 6 . Several studies also suggested the role of pangolin-related coronaviruses in the emergence of SARS-CoV-2 [7] [8] [9] . Since its appearance in humans, SARS-CoV-2 has evolved only through sporadic mutations, some of which correspond to gains in tness allowing the virus to spread more widely, or to escape neutralizing antibodies 13 . To decipher the origin of SARS-CoV-2, it is therefore essential to ascertain the diversity of animal coronaviruses and more speci cally of bat coronaviruses.

A majority of early human cases were found to be linked to the Huanan Seafood Market.\n6. The market had various animal meats, exotic seafood, and live animals available for purchase.\n7.

I have 1 read left, and I need to choose the most relevant paper to read.\n\nLet me analyze what I've already read and what I still need to know:\n\nPapers I've already read:\n1. \"An updated dataset of early SARS-CoV-2 diversity supports a wildlife market origin\" - This paper seems to support the zoonotic spillover hypothesis at the Huanan market.\n2. \"Surveillance of SARS-CoV-2 at the Huanan Seafood Market\" - This paper discusses the market's suspected role as the source of the pandemic.\n3. \"Identifying zoonotic origin of SARS-CoV-2 by modeling the binding affinity between Spike receptor-binding domain and host ACE2\" - This paper discusses the possible zoonotic origin from bats.\n4. \"Surveillance of SARS-CoV-2 in the environment and animal samples of the Huanan Seafood Market\" - This paper discusses surveillance at the market.\n5. \"Coronaviruses with a SARS-CoV-2-like receptor-binding domain allowing ACE2-mediated entry into human cells isolated from bats of Indochinese peninsula\" - This paper discusses bat coronaviruses similar to SARS-CoV-2.\n\nFrom these papers, I have some evidence supporting the zoonotic spillover hypothesis at the Huanan market, but I could benefit from reading one more paper that might provide additional evidence or a different perspective.\n\nLooking at the remaining papers, I notice there are several that seem to be duplicates or errata of papers I've already read. There's also a paper titled \"Wildlife trade drives animal-to-human pathogen transmission over 40 years\" which might provide broader context about zoonotic spillover events.\n\nLet me choose to read \"Wildlife trade drives animal-to-human pathogen transmission over 40 years\" (tt:1NAhHBQ5-1QR-2CMGNmzgekIrygu_MAKdCyjF4f7xr8) as it might provide additional context about how wildlife trade can lead to zoonotic spillover events, which is relevant to the Huanan market hypothesis.\n\nActually, I notice there's also a paper titled \"Preventing zoonotic spillover through regulatory frameworks governing wildlife trade: A scoping review\" (tt:3fll7ADMY3qqEiXBhLlIqettexRRrUsCbdY-autKpGg) which might also be relevant.\n\nAnd there's \"Exposure to diverse sarbecoviruses indicates frequent zoonotic spillover in human communities interacting with wildlife\" (tt:N5kM9nvS35RQkwUUm6-1979ygsqocAKzAFyw7lcFLVA) which could provide evidence about the frequency of zoonotic spillover events.\n\nLet me choose to read \"Wildlife trade drives animal-to-human pathogen transmission over 40 years\" as it seems most directly relevant to the Huanan market hypothesis, which involves wildlife trade.\n\nActually, I'm realizing that I've already read 5 papers, and the instructions say I have 1 read left. Let me double-check what I've read:\n\n1. tt:9bwwBcR6pLqwS-vOsvt1T1LHo7MSK93Islk_6HhOsq8 - \"An updated dataset of early SARS-CoV-2 diversity supports a wildlife market origin\"\n2. tt:I7XU3gQb0dX2_uDnoN4aWFGld4p0Qa7vgQYdThjUBuY - \"Surveillance of SARS-CoV-2 at the Huanan Seafood Market\"\n3. 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\"\n4. tt:2hB_6x4Opwdmb8Y5__jNLO8Ykk6JOkXPl8PeR9nZVAk - \"Surveillance of SARS-CoV-2 in the environment and animal samples of the Huanan Seafood Market\"\n5. tt:5Av3q_Yyc2jvYadPTn2w3vgwMPBgyaT4N27DtBCwiSc - \"Coronaviruses with a SARS-CoV-2-like receptor-binding domain allowing ACE2-mediated entry into human cells isolated from bats of Indochinese peninsula\"\n\nYes, I've read 5 papers, and I have 1 read left. Let me choose to read \"Wildlife trade drives animal-to-human pathogen transmission over 40 years\" (tt:1NAhHBQ5-1QR-2CMGNmzgekIrygu_MAKdCyjF4f7xr8).\n\nActually, I notice that there are multiple entries for \"Wildlife trade drives animal-to-human pathogen transmission over 40 years\" - tt:1NAhHBQ5-1QR-2CMGNmzgekIrygu_MAKdCyjF4f7xr8 and tt:mgfFgp0L95uxueR9nASX9G0Jj-T7BmaMZGW0h26kREI. I'll choose the first one.\n\nNow, let me build my argument based on the papers I've read and the one I'm about to read.\n\nFrom the papers I've already read, I have the following evidence:\n\n1. From \"An updated dataset of early SARS-CoV-2 diversity supports a wildlife market origin\":\n   - The earliest reported COVID-19 cases were associated with Wuhan's Huanan Seafood Wholesale Market.\n   - Spatiotemporal epidemiological data distinguished the area near the market as the epicenter of the outbreak.\n   - 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.\n   - A stall in the market contained nucleic acid from both SARS-CoV-2 and animals capable of SARS-CoV-2 transmission.\n\n2.

From \"Identifying zoonotic origin of SARS-CoV-2 by modeling the binding affinity between Spike receptor-binding domain and host ACE2\":\n   - SARS-CoV-2 shares a 96.2% nucleotide sequence identity with the bat coronavirus RaTG13.\n   - Natural insertions were identified at the S1/S2 cleavage site of the Spike protein of RmYN02-CoV.\n   - The binding efficiency of RaTG13 to human ACE2 is quite low, suggesting it might not directly infect humans.\n\n4. From \"Surveillance of SARS-CoV-2 in the environment and animal samples of the Huanan Seafood Market\":\n   - A majority of early human cases were found to be linked to the Huanan Seafood Market.\n   - The market had various animal meats and exotic seafoods available for purchase.\n   - 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.\n\n5. From \"Coronaviruses with a SARS-CoV-2-like receptor-binding domain allowing ACE2-mediated entry into human cells isolated from bats of Indochinese peninsula\":\n   - The closest SARS-CoV-2 bat-borne genome is from R. affinis, RaTG13.\n   - Several studies suggested the role of pangolin-related coronaviruses in the emergence of SARS-CoV-2.\n\nNow, let me read the paper \"Wildlife trade drives animal-to-human pathogen transmission over 40 years\" to get additional evidence.\n\n{\"read\": \"tt:1NAhHBQ5-1QR-2CMGNmzgekIrygu_MAKdCyjF4f7xr8\"}\n\nIt seems that the paper wasn't actually read.

The convergence of epidemiological, genetic, and environmental evidence points to the market as the epicenter of the outbreak, with conditions conducive to zoonotic transmission from animals to humans.\", \"citations\": [{\"claim\": \"The earliest reported COVID-19 cases were associated with Wuhan's Huanan Seafood Wholesale Market\", \"tt\": \"tt:9bwwBcR6pLqwS-vOsvt1T1LHo7MSK93Islk_6HhOsq8\", \"quote\": \"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] .\"}, {\"claim\": \"Spatiotemporal epidemiological data distinguished the area near the market as the epicenter of the outbreak\", \"tt\": \"tt:9bwwBcR6pLqwS-vOsvt1T1LHo7MSK93Islk_6HhOsq8\", \"quote\": \"Spatiotemporal epidemiological data unambiguously distinguished the area near the market as the epicenter of the outbreak [5] [6] [7] [8] .\"}, {\"claim\": \"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\", \"tt\": \"tt:9bwwBcR6pLqwS-vOsvt1T1LHo7MSK93Islk_6HhOsq8\", \"quote\": \"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] .\"}, {\"claim\": \"A stall in the market contained nucleic acid from both SARS-CoV-2 and animals capable of SARS-CoV-2 transmission\", \"tt\": \"tt:9bwwBcR6pLqwS-vOsvt1T1LHo7MSK93Islk_6HhOsq8\", \"quote\": \"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] .\"}, {\"claim\": \"A majority of early human cases were found to be linked to the Huanan Seafood Market\", \"tt\": \"tt:I7XU3gQb0dX2_uDnoN4aWFGld4p0Qa7vgQYdThjUBuY\", \"quote\": \"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.\"}, {\"claim\": \"The market had various animal meats, exotic seafood, and live animals available for purchase\", \"tt\": \"tt:I7XU3gQb0dX2_uDnoN4aWFGld4p0Qa7vgQYdThjUBuY\", \"quote\": \"where various animal meats, exotic seafood and live animals were available for purchase.\"}, {\"claim\": \"SARS-CoV-2 shares a 96.2% nucleotide sequence identity with the bat coronavirus RaTG13\", \"tt\": \"tt:buS-VjbFvU_GGHRdwTWe7VrhK_eQ2HyhNMEPlJZ2BbE\", \"quote\": \"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]\"}, {\"claim\": \"Not all early human cases had epidemiological links to the market\", \"tt\": \"tt:I7XU3gQb0dX2_uDnoN4aWFGld4p0Qa7vgQYdThjUBuY\", \"quote\": \"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.\"}, {\"claim\": \"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\", \"tt\": \"tt:2hB_6x4Opwdmb8Y5__jNLO8Ykk6JOkXPl8PeR9nZVAk\", \"quote\": \"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) .\"}, {\"claim\": \"The binding efficiency of RaTG13 to hACE2 is quite low\", \"tt\": \"tt:buS-VjbFvU_GGHRdwTWe7VrhK_eQ2HyhNMEPlJZ2BbE\", \"quote\": \"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.\"}]}}",
