The deadly Chinese coronavirus outbreak began at a wholesale animal market in Wuhan city, experts have confirmed.
Scientists from the Chinese Centre for Disease Control and Prevention said tests proved humans caught it from animals at the Huanan Seafood Wholesales Market.
It is not clear which animal was carrying the pneumonia-like illness but the market was home to stalls trading dozens of different species, including rats and wolf cubs.
Last week experts suggested the disease may have originated in snakes, which are known carriers of coronaviruses.
The Huanan market was a hotspot with locals, who could choose to buy their meat ‘warm’ meaning it had been slaughtered just moment prior.

‘Thirty-one of the 33 positive samples were collected from the western zone of the market, where booths of wildlife trading concentrated,’ the CDC said, according to China’s state-owned Xinhua news agency.
‘The result suggests that the novel coronavirus outbreak is highly relevant to the trading of wild animals.’
The epidemic has so far claimed the lives of more than 80 people and infected nearly 3,000 in a month – but experts predict that number to be closer to 100,000.
Chinese authorities temporarily barred the trading of wild animals on Sunday. The Government said those who ignored the ban would be ‘severely investigated and punished’.
Public health experts had previously warned that China’s live animal markets were the perfect breeding ground for emerging infectious diseases.
A total of 15 countries or territories outside of China have now confirmed cases, with Sri Lanka and Cambodia the latest to announce and a second case diagnosed in Canada today, in the wife of the Toronto man who was the first patient.
The coronavirus outbreak has now killed 82 people and struck down more than 2,800. Cambodia today became the latest country to confirm the virus has spread there. The government confirmed a Chinese national who travelled to the city of Sihanoukville was infected

CORONAVIRUS: WHAT WE KNOW SO FAR
The virus has been identified as a new type of coronavirus. Coronaviruses are a large family of pathogens, most of which cause mild respiratory infections such as the common cold.
But coronaviruses can also be deadly. SARS, or severe acute respiratory syndrome, is caused by a coronavirus and killed hundreds of people in China and Hong Kong in the early 2000s.
Can it kill?
Yes. Eighty-one people have so far died after testing positive for the virus.
What are the symptoms?
Its symptoms are typically a fever, cough and trouble breathing, but some patients have developed pneumonia, a potentially life-threatening infection that causes inflammation of the small air sacs in the lungs. People carrying the novel coronavirus may only have mild symptoms, such as a sore throat. They may assume they have a common cold and not seek medical attention, experts fear.
How is it detected?
The virus’s genetic sequencing was released by scientists in China to the rest of the world to enable other countries to quickly diagnose potential new cases. This helps other countries respond quickly to disease outbreaks.
To contain the virus, airports are detecting infected people with temperature checks. But as with every virus, it has an incubation period, meaning detection is not always possible because symptoms have not appeared yet.
How did it start and spread?
The first cases identified were among people connected to the Huanan Seafood Wholesale Market in Wuhan.
Cases have since been identified elsewhere which could have been spread through human-to-human transmission.
What are countries doing to prevent the spread?
Countries in Asia have stepped up airport surveillance. They include Japan, South Korea, Thailand, Hong Kong, Indonesia, Malaysia and Philippines.
Australia and the US are also screening patients for a high temperature, and the UK announced it will screen passengers returning from Wuhan.
Is it similar to anything we’ve ever seen before?
Experts have compared it to the 2003 outbreak of severe acute respiratory syndrome (SARS). The epidemic started in southern China and killed more than 700 people in mainland China, Hong Kong and elsewhere
Beijing also today saw the Wuhan coronavirus claim its 82nd death when a 50-year-old man died in hospital in the nation’s capital at around 8pm local time (12pm GMT).
China has extended its New Year holiday by three days to February 2 to fight the outbreak as people have now been diagnosed with it in every corner of China, except for Tibet.
A team of scientists in the UK believe more than 100,000 people have been infected already but many of them without knowing, and expect the case and death tolls both to continue rising as the outbreak goes on.
The damage has spread to the stock markets, too, as investors fear travel cancellations and business closures, as well as growing panic outside of China, are damaging the world economy.
Researchers in Hong Kong have warned the outbreak could become a ‘global epidemic’ if the Chinese government doesn’t start ‘draconian’ travel restrictions on its citizens.
Beijing insists it is continuing drastic efforts to contain the outbreak.
New cases today include the first to be diagnosed in Cambodia, in a Chinese national, and a second in Toronto, Canada, where the wife of the first Canadian patient is now being treated for coronavirus.
The disease’s spread has seemed all but unstoppable over the last week, and scientists at Hong Kong University say more drastic action needs to be taken.
There is a risk the virus could trigger a global epidemic – when the illness spreads uncontrollably around the world – if the Chinese government doesn’t clamp down on the movement of people, the researchers said.
‘We have to be prepared that this particular epidemic may be about to become a global epidemic,’ said Dr Gabriel Leung.
‘Substantial, draconian measures limiting population mobility should be taken sooner, rather than later.’
Concerns about the virus have been growing as scientists say people may be passing on the virus before they even realise they are ill, and the number of predicted cases has soared dramatically.
China’s health minister Ma Xiaowei said yesterday ‘it seems like the ability of the virus to spread is getting stronger’ and that it can be passed from person-to-person even before symptoms appear.
And researchers at Imperial College London have estimated that more than 100,000 people may be infected around the world already. The same team had previously thought the number was around 4,000, up to 10,000.
Professor Mark Harris, from the University of Leeds, said: ‘Its true that the numbers… look scary.
‘One positive spin is that if we are only aware of five per cent of the total cases, the implication is that 95 per cent of cases have only resulted in either mild symptoms such that the infected people did not consider it serious enough to seek medical help, or indeed the virus may be causing an inapparent infection.
‘This would significantly reduce the apparent [death] rates.’
The mayor of Wuhan, where the outbreak started, has admitted he and the ruling Chinese Communist Party did not react quickly enough to the coronavirus danger.
