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\nReply with ONE JSON object, no prose:\n  to read a paper:  {\"read\": \"<tt:...>\"}\n  to finish:        {\"conclude\": {\"argument_md\": \"<markdown>\", \"citations\": [{\"claim\": \"...\", \"tt\": \"<tt:...>\", \"quote\": \"<exact substring of a paper you read>\"}]}}\nEvery citation quote MUST be copied verbatim from a paper you have read above."}], "temperature": 0.3, "max_tokens": 8000, "provider": {"ignore": ["Novita"]}}
