THECONVERSATION 15/03/20 Snakes make good food. Banning farms won’t help the fight against coronavirus. The wildlife trade has long been closely linked to disease outbreaks.
It has been implicated in the SARS epidemic of 2002, Ebola in 2013 and now in the COVID-19 coronavirus. In response to the COVID-19 outbreak, China has tentatively banned the farming of many wildlife species. The move has been celebrated by many in the international community. But our work in Asia over the past ten years tells a different story. Banning legitimate snake farms might prove counterproductive to disease suppression. Though snakes were early suspects as the source of the Wuhan coronavirus, reptiles have never been linked to any of the World Health Organisation’s top ten infectious diseases which pose the greatest threat of epidemics. LE MONDE 28/01/20 LES DECODEURS - Il n’est pas prouvé que le coronavirus provienne des serpents ou de la soupe de chauve-souris.
Depuis l’apparition d’une nouvelle épidémie de coronavirus en Chine, en décembre 2019, les rumeurs sur son origine se propagent rapidement.
Le coronavirus 2019-nCoV a émergé à Wuhan, une ville située dans l’est de la Chine. A l’heure actuelle, mercredi 29 janvier, l’épidémie a causé la mort de 132 personnes dans le pays et s’est propagée à l’étranger (quatre cas ont été confirmés en France) sans provoquer aucun décès. Alors que l’Organisation mondiale de la santé (OMS) a qualifié la menace liée au virus, d’« élevée » le 27 janvier, plusieurs sites et publications sur les réseaux sociaux ont relayé des thèses non confirmées sur l’origine de ce nouveau virus.
Selon eux, le virus aurait pour origine des serpents ou des chauves-souris qui, consommées en soupe, auraient contaminé une partie de la population chinoise. SCIENCENEWS 24/01/20 No, snakes probably aren’t the source of that new coronavirus in China. An outbreak of a pneumonia-like virus in China has scientists puzzling over the disease’s origins and searching for animals that may have spread it to humans.
A new study points to snakes as the culprit, but other researchers are skeptical. It’s unlikely the virus jumped from a reptile to a human, says Edward Holmes, a virologist at the University of Sydney. “I can’t categorically say it’s never happened,” he says. “But the [animal] reservoirs for human viruses are mainly mammals and maybe birds.” Animals are often the source of human disease outbreaks. The current outbreak in China is caused by a coronavirus, a group of viruses behind diseases such as the common cold, as well as the more deadly severe acute respiratory syndrome, or SARS, and Middle East respiratory syndrome, or MERS (SN: 1/23/20).

VIROLOGICAL 22/01/20 nCoV’s relationship to bat coronaviruses & recombination signals (no snakes) NATURE 23/01/20 Why snakes probably aren’t spreading the new China virus. As human cases rise in a mysterious viral outbreak that originated in China, scientists are rushing to identify the animals, where they suspect the epidemic began.
In a controversial study published last night, a team of researchers in China claimed to have an answer: snakes. But other scientists say there is no proof that viruses such as those behind the outbreak can infect species other than mammals and birds. “Nothing supports snakes being involved,” says David Robertson, a virologist at the University of Glasgow, UK. The pathogen responsible for the outbreak belongs to a large family called coronaviruses, which includes the viruses that cause severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), as well as those behind the common cold. The latest virus — currently known as 2019-nCoV — is most closely related to SARS and related viruses that circulate in bats. Hedgehogs, chickens and bats Evidence gap.

THE CONVERSATION 22/01/20 Snakes Could Be the Original Source of the New Coronavirus Outbreak in China. The following essay is reprinted with permission from The Conversation, an online publication covering the latest research.
Snakes—the Chinese krait and the Chinese cobra—may be the original source of the newly discovered coronavirus that has triggered an outbreak of a deadly infectious respiratory illness in China this winter. The many-banded krait (Bungarus multicinctus), also known as the Taiwanese krait or the Chinese krait, is a highly venomous species of elapid snake found in much of central and southern China and Southeast Asia. NEW SCIENTIST 22/01/20 Wuhan coronavirus may have been transmitted to people from snakes. By Jessica Hamzelou Roslan Rahman/AFP via Getty Images A new coronavirus originating in Wuhan, China, that has claimed 17 lives may have been transmitted to people from snakes, according to a genetic analysis.
The snakes may have caught the virus from bats in the food market in which both animals were sold. As of 22 January, there are 555 confirmed cases of the infection, which can cause fever, difficulty breathing and pneumonia. To contain the virus, Wuhan has effectively been placed under quarantine, with public transport being temporarily closed, according to reports. While 444 of the cases have been reported in Wuhan, others have also been confirmed in the surrounding regions of China, with 26 in Guangdong province, 14 in Beijing and 9 in Shanghai. The source of the infection is suspected to be a food market in Wuhan that was visited by several of those first infected with the virus. The virus may then have passed to people through the air, says Rabinowitz.

The deadly coronavirus that has so fair claimed 17 lives in Wuhan, China, may have been transmitted to people from snakes, according to a genetic analysis, New Scientist reported.
The snakes may have been infected with the virus from bats in a food market in which both species were sold. The outbreak of coronavirus has been linked to a fish market at Wuhan, the capital of China’s central Hubei province. The Wuhan South China Seafood City market, which also sells chickens, bats, marmots and other animals, has been closed since 1 January. In Chinese food tradition, even roaches, rats, dogs, monkeys are not shunned.
Battling to spread the infection, Chinese authorities moved to place the city of Wuhan under complete quarantine in an attempt to slow the outbreak of a new coronavirus that originated in the city. Trains and flights to Wuhan have been temporarily halted. CNEWS 23/01/20 Serpents et chauve-souris à l'origine du coronavirus chinois ? L'origine du coronavirus venu de Chine, qui a déclenché une épidémie de pneumopathies au-delà des frontières du pays, se précise. Selon une étude publiée mercredi 22 janvier dans Journal of Medical Virology, les serpents pourraient être à l'origine du virus. On savait déja que l'épidémie était partie d'un marché à Wuhan, et que le virus s'était transmis d'un animal à l'Homme.
Les scientifiques à l'origine de cette étude ont ainsi analysé la séquence exhaustive du virus pour la comparer avec les autres types de coronavirus présents dans l'organisme d'animaux présents sur ce marché.
