The Wuhan Huanan Seafood Wholesale Market (

Jianghan District, Wuhan, the capital of Hubei Province, in Central China
. The market opened on 19 June 2002.

The market became widely known worldwide after being identified by some sources as the

SARS-CoV-2
infection, by 2 January 2020, two-thirds were exposed to the market.

The market was closed permanently on 1 January 2020 for sanitary procedures and disinfection.[1][5] Thirty-three out of 585 environmental samples (5.6%) obtained from the market indicated evidence of COVID-19 outbreak, according to the Chinese Center for Disease Control and Prevention.[6][7]

Facility and operations

The market occupied over 50,000 m2 (12 acres)

Wuhan Center for Disease Control.[13]

In late 2019, the market passed city official inspections, according to The Wall Street Journal.[6] However, Time reported it to have "unsanitary" conditions.[14] It had narrow lanes and stalls in close proximity, where livestock were kept alongside dead animals. According to Business Insider, it was common to see animals openly slaughtered and carcasses skinned in the market.[15] The New York Times reported that "sanitation was dismal, with poor ventilation and garbage piled on wet floors."[11]

The Huanan seafood market was the ground floor of the building. Following its closure, it was sanitized in depth and did not reopen. On the second floor, there is Huanan Glasses Wholesale City (华南眼镜批发城), which closed only during the Wuhan lockdown and is still in operation.[16][17]

Items sold

With local demand present for the consumption of exotic animals, the market also offered exotic game (

Dazhong Dianping listed 112 items, including a number of wild animals.[3][8][24] The South China Morning Post reported on 29 January 2020, that the market had a section selling around "120 wildlife animals across 75 species."[25]

It was incorrectly reported that koalas were sold at the market. The price list included "树熊" (pinyin: shùxióng; lit. 'tree bear'). This term is used for koalas in Chinese communities in Singapore, Malaysia, and Hong Kong, but in China, they are called "考拉" (read as "kǎolā").[24] At the Huanan market, 'tree bear' referred to large rodents.[24]

According to a study published in

coypus, marmots, red foxes, minks, red squirrels, wild boars, and complex-toothed flying squirrels. The wild animals on sale suffered poor welfare and hygiene conditions and were capable of hosting a wide range of infectious zoonotic diseases or disease-bearing parasites. No pangolin or bat species were among the animals for sale.[26]

Risks identified pre-pandemic

Even before the pandemic, the market was identified as a likely site for zoonosis (diseases hopping to humans from other species). There were over a thousand raccoon-dogs for sale in the market, and about nine thousand other animals.[27] Samples collected in the market in early 2020 showed high levels of SARS-CoV-2 and raccoon-dog genetic material (often both in the same samples), especially from a stall ("Stall 29") that kept a cage of raccoon-dogs on top of a cage containing poultry, optimum conditions for the virus to hop the species barrier.

The existence of such a stall has been contested by Chinese authorities;

Weibo.[29][30][28] Raccoon-dogs are known to be able to catch and spread COVID-19 easily.[30]

These samples were swabs of surfaces in the market. Samples from the actual animals in the market would be more conclusive but were not collected.[29][30] The market was closed on January 1,[27] and the animals had been removed before public-health authorities from the Chinese CDC came in.[30][28] Although the samples do not definitively prove that the raccoon dog is the "missing" intermediate animal host in the bat-to-human transmission chain, it does show that raccoon dogs were present in the Huanan market at the time of the initial SARS-CoV-2 outbreak, in areas that were also positive for SARS-CoV-2 RNA, and substantially strengthens this hypothesis as the proximal origin of the pandemic.[30][29]

Early identification of potential pandemic link (2019–2020)

In December 2019, an epidemic of a

MERS-CoV) mainly circulate among non-human animals, and with a link between the pneumonia outbreak and the market being established, it was suspected that the virus may have been passed from an animal to humans (zoonosis).[33][34]

Bats were initially suggested to be the source of the virus, although it remains unclear if bats were sold there.

pangolins may be the intermediate host of the virus originating from bats, analogous to the relationship between SARS-CoV and civets.[39][40] Phylogenetic analysis indicates that pangolins are a potential reservoir host rather than the intermediate host of SARS-CoV-2. While there is scientific consensus that bats are the ultimate source of coronaviruses, SARS-CoV-2 originated from a pangolin, jumped back to bats, and then jumped to humans, according to phylogenetic analysis. Therefore, a specific population of bats is more likely to be the intermediate host for SARS-CoV-2 than a pangolin, while an evolutionary ancestor to bats was the source for general coronaviruses.[41]

Despite the role that the market played in the pandemic, it is yet unclear whether the novel coronavirus outbreak started in the market.

hospitalized patients who had confirmed infections with SARS-CoV-2.[45] Their data showed 13 of the initial 41 people found with the novel coronavirus had no link with the market, a significant figure, according to infectious diseases specialist Daniel Lucey.[5][44][45] In a later publication, The Lancet reported that of the first 99 people confirmed with COVID-19 in Wuhan Jinyintan Hospital between 1 and 20 January 2020, 49 had a history of exposure to the market. The publication nevertheless did not opinionate on whether the market was the origin or just a key link in the epidemic.[46]

In an attempt to discover the origin of SARS-CoV-2, samples from the market's animals[

In May 2020,

superspreading event, but it was not the site of the initial outbreak.[51] On 11 December 2020, Reuters reported that the market was still empty and barricaded.[52]

WHO investigation and later assessments (2021–2023)

On 31 January 2021, a team of scientists led by the World Health Organization visited the wet market to investigate the origins of COVID-19.[53] The WHO investigation determined that despite cluster cases there in an early outbreak and some contaminated surfaces found, no infected animal was found, concluding that human to human transmission at the market was likely, with the origin site still unknown.[54]

In late July 2022, two papers were published in the journal Science, both describing evidence that the pandemic likely began at the market, and probably did not originate at a laboratory.[55][56][57][58] The Chinese government has long insisted that the virus originated outside China,[30] and until June 2021, denied that live animals were traded at the Huanan market.[27]

Some Chinese researchers had published a

French National Center for Scientific Research, stumbled across the samples on March 4, 2023, and brought them to the attention of others. An international team of researchers assembled to analyse the new data, but when they reached out to the Chinese researchers[29] from the Chinese Center for Disease Control and Prevention who uploaded the data,[30] there was no reply and the samples were removed from the public database by the uploaders. Analysis of the downloaded sequences was proceeding without Chinese collaboration, as of 16 March 2023.[29]

On 14 March, the international group of researchers presented a preliminary analysis at a meeting of the World Health Organization's Scientific Advisory Group for Origins of Novel Pathogens, at which, several of the Chinese researchers were present. Shortly afterwards, changes in the status of the preprint suggested that it is now under review for print publication.[30] The international research team welcomed the move and hoped the Chinese team's paper would be revised to include the full genetic data, saying they would also be publishing an analysis and hoped that, as scientists, they would work together on the issues.[27]

The

Science that there was "nothing new" in the raw data, and refused to answer questions about why his research team had removed it from the database.[27] On 17 March, the WHO director-general said that the data should have been shared three years earlier, and called on China to be more transparent in its data-sharing.[30] Maria Van Kerkhove, the WHO’s COVID-19 technical lead, called for this data to be made public immediately.[30]

Responses

Closure

On 1 January 2020, in response to the initial outbreak of the pneumonia cluster, the health authorities closed the market to conduct investigations, clean, and disinfect the location.[1][34]

Ban on wild animal trade

Chinese environmentalists, researchers, and state media have called for stricter regulation of exotic animal trade in wet markets.[59] Several Chinese scientists have called for bans on wildlife trade since 2003.[25][60][61]

On 22 January 2020, a ban on the sale of all wild animal products in Wuhan was announced.[62] In May 2020, the city banned eating wild animals and limited hunting and breeding of wild animals.[63]

On 24 February 2020, the Chinese government announced that the trade and consumption of wild animals would be banned throughout China,[64][65] amidst mounting domestic criticism of the industry.[66][67][68][69] However, the ban does not cover the consumption of wild animal products in traditional Chinese medicine, according to The New York Times.[70]
