An “intermediate host” animal passed the coronavirus from wild bats to humans, evidence suggests.
But while the World Health Organization says that the research points to the virus’s “natural origin”, some scientists say it might never be known how the first person was infected.
It remains unclear whether this host animal was sold in the now infamous Wuhan wildlife market in China.
But the wildlife trade is seen as a potential source of this “spillover”.
Researchers say the trade provides a source of species-to-species disease transmission, which caused previous outbreaks and has been blamed for this pandemic.
The WHO’s technical lead on Covid-19, Dr Maria Van Kerkhove, told the BBC’s Andrew Marr show: “We were preparing for something like this as it’s not a matter of if, it is a matter of when.”
The spillover
Infectious disease experts agree that, like most emerging human disease, this virus initially jumped undetected across the species barrier.
Prof Andrew Cunningham, from the Zoological Society of London, explained: “We’ve actually been expecting something like this to happen for a while.
“These diseases are emerging more frequently in recent years as a result of human encroachment into wild habitat and increased contact and use of wild animals by people.”
Officials seize civet cats in Xinyuan wildlife market in Guangzhou to prevent the spread of SarsThe virus that causes Covid-19 is far from the first case of such spillover. It joins a murky list of household name viruses – including Ebola, rabies, Sars and Mers – that have originated in wild bat populations. Some of the now extensive body of evidence about bat viruses, and their ability to infect humans, comes from searching for the source of the 2003 outbreak of Sars, a very closely related coronavirus.
What viruses needed in order to infect a new host is the ability to “unlock” and get inside a cell to replicate. And, like Sars, the ancestral bat coronavirus appears to have held the human cellular key. “In the case of Sars-CoV-2 the key is a virus protein called Spike and the main lock to enter a cell is a receptor called ACE2,” explained Prof David Robertson, a virologist from the University of Glasgow.
“The coronavirus is not only able to fit that ACE2 lock, “it’s actually doing this many times better than Sars-1 does”, he said.
Coronaviruses under the microscopeThat perfect fit could explain why the coronavirus is so easily transmitted from person to person; its contagiousness has outpaced our efforts to contain it. But bringing the bat virus to the door of a human cell is where the trade in wildlife plays an important role.
Buying, selling, infecting
Most of us have heard that this virus “started” in a wildlife market in Wuhan. But the source of the virus – an animal with this pathogen in its body – was not found in the market.
“The initial cluster of infections was associated with the market – that is circumstantial evidence,” explained Prof James Wood from the University of Cambridge.
“The infection could have come from somewhere else and just, by chance, clustered around people there. But given that it is an animal virus, the market association is highly suggestive.”
Prof Cunningham agreed; wildlife markets, he explained, are hotspots for animal diseases to find new hosts. “Mixing large numbers of species under poor hygienic and welfare conditions, and species that wouldn’t normally come close together gives opportunities for pathogens to jump species to species,” he explained.
Animals rescued from the exotic pet trade often have to be protected from human diseaseMany wildlife viruses in the past have come into humans via a second species – one that is farmed, or hunted and sold on a market.
Prof Woods explained: “The original Sars virus was transmitted into the human population via an epidemic in Palm civets, which were being traded around southern China to be eaten.
“That was very important to know because there was an epidemic in the Palm civets themselves, which had to be controlled in order to stop an ongoing process of spillover into humans.”
In the search for the missing link in this particular transmission chain, scientists have found clues pointing to mink, ferrets and even turtles as a host. Similar viruses were found in the bodies of rare and widely trafficked pangolins, but none of these suspect species has been shown to be involved in this outbreak. What we do know is that our contact with and trading of wild animals puts us – and them – at risk.
Camels can harbour the novel coronavirus, Mers“Trying to make sure that we are not bringing wildlife into direct contact with ourselves or with other domestic animals is a very important part of this equation,” said Prof Wood.
Regulating the global trade in wildlife, though, is far from straightforward.”
“There have been various campaigns to ban all trade in animals and all contact with wildlife,” said Prof Wood. “But typically what you do then is penalise some of the poorest people in the world. In many cases, by introducing measures like that you drive trade underground, which makes it far harder to do anything about.”
The WHO has already called for stricter hygiene and safety standards for so-called wet markets in China. But in many cases – such as the trade in bushmeat in Sub-Saharan Africa, which was linked with the Ebola outbreak – markets are informal and therefore very difficult to regulate.
“You can’t do it from an office in London or in Geneva; you have to do that locally on the ground in every country,” added Prof Wood.
Dr Maria Van Kerkhove agreed: “It’s very important we work with population and people who are working at the animal/human interface – people who work with wildlife.”
What that will be is a truly global and highly complicated effort. But the Covid-19 outbreak appears to have shown us the cost of the alternative.
Dozens of Palestinians killed in overnight Israeli strikes in central and south Gaza as Red Sea tensions rise.
Here’s how things stand on Monday, January 15, 2024:

Flames and smoke billow during Israeli attacks against Gaza on October 9, 2023
Human Rights Watch terms Israeli Defence Minister Yoav Gallant’s call for a ‘complete siege’ on Gaza a ‘war crime’.
The Hamas movement has threatened to kill an Israeli hostage every time Israel bombs a Palestinian home without warning as Israel mobilised some 300,000 reservists and imposed a total blockade of the Gaza Strip, denying the enclave’s millions of residents access to food, water and fuel.
The warning from Hamas came on Monday as the death toll from the armed group’s surprise weekend attack climbed to 900 in Israel and revenge attacks by Israeli forces on the besieged Gaza Strip killed more than 700 people and left some 3,700 others wounded.
Residential apartment blocks, hospitals, schools and a mosque have been among the sites attacked by Israeli fighter jets, artillery and drones, according to media reports and witnesses.
Hamas spokesperson Abu Ubaida issued the threat to kill Israelis from the dozens held captive by the armed group. He said an Israeli hostage would be killed for every Israeli bombing of a civilian house without warning.
Israeli Foreign Minister Eli Cohen said more than 100 people were taken captive by Hamas during the deadly cross-border incursion over the weekend.
As Israeli forces conducted intense retaliatory attacks on Gaza on Monday, Israel’s Defence Minister Yoav Gallant drew international condemnation by announcing a total blockade of the densely populated and besieged enclave, which is home to 2.3 million people.
Gallant said Israel would impose a “complete siege” on Gaza. “No electricity, no food, no water, no gas – it’s all closed.”
United Nations Secretary-General Antonio Guterres said he was “deeply distressed” by the siege announcement and warned that Gaza’s already dire humanitarian situation will now “only deteriorate exponentially”.
Guterres also said some 137,000 people were taking shelter with the UN Relief and Works Agency for Palestinian Refugees (UNRWA) at schools across Gaza.
UNRWA said on Tuesday that almost 190,000 people have been displaced in Gaza amid the Israeli attacks and the figure is expected to grow further as the violence intensifies.
Nearly half a million people have also not received food rations this week in Gaza as UN food distribution centres have been forced to remain closed amid the Israeli onslaught, UNRWA said.
Human Rights Watch said Israel’s total blockade on the necessities of life for everyday people in Gaza was a war crime.
“Defense Minister Gallant’s statements are abhorrent,” Omar Shakir, Israel and Palestine director at Human Rights Watch, said in a statement.
“Depriving the population in an occupied territory of food and electricity is collective punishment, which is a war crime, as is using starvation as a weapon of war. The International Criminal Court should take note of this call to commit a war crime,” he said.
Abhorrent. This is a call to commit a war crime by @yoavgallant. The @IntlCrimCourt should take note.

Shakir also condemned the threat by Hamas to kill hostages, warning that such action was also a war crime.
“All hostages should be safely released to their families,” he said.
Grotesque. These threatened acts would amount to flagrant war crimes by Hamas’ armed wing. The @IntlCrimCourt will be watching.

On the diplomatic front, Egyptian President Abdel Fattah el-Sisi and his Turkish counterpart Recep Tayyip Erdogan called on Hamas and Israel to immediately end violence and protect civilians, the Egyptian presidency said.
Erdogan urged Israel against “indiscriminately” attacking civilians and delivered measured criticism of Hamas, urging both sides to respect the “ethics” of war.
The United Kingdom, French, German, Italian and US governments issued a joint statement on Monday recognising the “legitimate aspirations” of the Palestinian people and supporting equal measures of justice and freedom for Israelis and Palestinians alike.
But the prospect that fighting could spread also alarmed the region and the world.
Lebanese armed group Hezbollah fired rockets into northern Israel in response to at least three of its members being killed in Israeli shelling of Lebanon.
Israel said one of its deputy commanders was also killed in an earlier cross-border raid from Lebanon.

Social media users, including journalists and observers, are calling out what they call a ‘double standard’.
After Saturday’s surprise attack by the Palestinian group Hamas on Israel, Ukrainian President Volodymyr Zelenskyy took to the social media platform X to offer “condolences go out to everyone who lost relatives or close ones in the terrorist attack”.
He also stated, “Israel’s right to self-defence is unquestionable.”
Many world leaders, including US President Joe Biden and UK Prime Minister Rishi Sunak, shared similar sentiments.
The world is seeing appalling images.
Thousands of rockets raining down on Israeli cities. Hamas terrorists killing not only Israeli soldiers, but civilians on the streets and in their homes.
It’s unconscionable. Israel has a right to defend itself – full stop.
— President Biden (@POTUS) October 7, 2023
European Commission President Ursula von der Leyen stated, “Israel has the right to defend itself – today and in the days to come. The European Union stands with Israel.”
Accusations of Western ‘double standards’
Some social media users have criticised these statements, saying they highlight a double standard.

Ukraine’s right to defend itself is praised by most international leaders while Russia’s invasion is condemned, but commentators said the same cannot be said about Israel’s occupation of the West Bank and Gaza.
Aaron Bastani, a leftist British journalist, said on X that there’s a “clear double standard in endorsing terrorism against civilian targets in Ukraine … and condemning it by Palestinians”.
Many users said Western diplomats and media support the Ukrainians who defend their land, but label the Palestinians fighting against Israel as “terrorists”.

An illustration of a woman’s face, in which one eye is closed beside a Palestinian flag, and one eye open beside a Ukrainian flag, has been regularly shared as a symbol of the West’s alleged double standards in how the two conflicts are viewed.
https://twitter.com/OnlinePalEng/status/1710994682883273172?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1710994682883273172%7Ctwgr%5E6acf829869e993177f32aa38aa48c02f38cb7f61%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fwww.aljazeera.com%2Fnews%2F2023%2F10%2F9%2Fwestern-leaders-accused-of-hypocrisy-over-response-to-palestine-ukraine
Clips also emerged on social media from a CNN interview with Mustafa Barghouti, the general secretary of the Palestinian National Initiative, in which he posed the rhetorical question, “Why does the United States support Ukraine in fighting occupation – while here they support the occupier, who continues to occupy us?”
The hypocrisy and double standards of western governments and media platforms dealing with situations in Ukraine-Russia and Palestine-Israel blow the mind. Absolute disgrace.
— Said Yacoubi (@AlyacoubiSaid) October 8, 2023
It is not the first time Western nations have been accused of double standards in their stance on the Ukraine war.
Earlier in the year, Amnesty International published a report highlighting the West’s “double standards” on global human rights.
Agnes Callamard, Amnesty’s secretary-general, told Al Jazeera at the time that the occupation of Palestinian territory was a “particularly important one”.
“Without making any comparison between Russia’s aggression and Israel … it is clear the Palestinian people are under a regime of oppression – a regime of occupation and a regime of apartheid,” Callamard told Al Jazeera.
Over the last three days, X users recirculated earlier statements calling out what they called Western hypocrisy, sharing video by the Irish lawmaker Richard Boyd Barrett from March 2022 in which he berated the Irish government’s double standards regarding Ukraine and Palestine:
“You’re happy to use the most strong and robust language to describe the crimes against humanity of [Russian President] Vladimir Putin, but you will not use the same strength of language when it comes to describing Israel’s treatment of the Palestinians.”
Barrett on Sunday again called out what he described as “shocking double standards of Western leaders supporting Ukraine resistance but condemning Palestinian[s].”
Meanwhile, others warned against comparing conflicts.

And some cautioned that Hamas and the Palestinians should not be seen as one and the same.
Just to clarify:
Palestine did not mount an attack on Israel. An Iranian proxy militia did. Palestinians are by and large huddled in their homes praying that an Israeli airstrike won't kill them or theirs. Hamas is the culprit here. This isn't a decentralized grassroots thing.

Ukrainian footballer Oleksandr Zinchenko, who plays for Arsenal, posted on Instagram, stating he “stands with Israel”.
Zinchenko has been a vocal supporter of his home country in its ongoing defence against Russia, and he participated in a Game4Ukraine charity match in London earlier this year to raise money for Ukraine.
After online backlash, with some questioning an alleged double standard in his support of Israel, the footballer removed the post and switched his social media account to private.
Several people claimed that Zinchenko’s football club, in not responding to his comments, was guilty of hypocrisy after they had distanced themselves from former player Mesut Ozil’s comments in 2019 over alleged human rights abuses against Uighur Muslims in China.
