The spread of a deadly new virus is accelerating, Chinese President Xi Jinping warned, after holding a special government meeting on the Lunar New Year public holiday.The country is facing a "grave situation" Mr Xi told senior officials.The coronavirus has killed at least 56 people and infected almost 2,000 since its discovery in the city of Wuhan.The US has announced that staff at the Wuhan consulate will be evacuated on a special flight on Tuesday.
The State Department said that private Americans most at risk will also be able to board the flight to San Francisco.Meanwhile, UK-based researchers have warned of a real possibility that China will not be able to contain the virus.Travel restrictions have come in place in several affected cities. From Sunday, private vehicles will be banned from central districts of Wuhan, the source of the outbreak.A second emergency hospital is to be built there within weeks to handle 1,300 new patients, and will be finished in half a month, state newspaper the People's Daily said. It is the second such rapid construction project: work on another 1,000-bed hospital has already begun.Specialist military medical teams have also been flown into Hubei province, where Wuhan is located.
The urgency reflects concern both within China and elsewhere about the virus which first appeared in December.
Lunar New Year celebrations for the year of the rat, which began on Saturday, have been cancelled in many Chinese cities.Across mainland China, travellers are having their temperatures checked for signs of fever, and train stations have been shut in several cities.In Hong Kong, the highest level of emergency has been declared and school holidays extended.Several other nations are each dealing with a handful of cases, with patients being treated in isolation.
A coronavirus is a family of viruses which include the common cold.But this virus has never been seen before, so it's been called 2019-nCov, for "novel coronavirus".New viruses can become common in humans after jumping across the species barrier from animals.The Sars [Severe Acute Respiratory Syndrome] outbreak of 2003 started in bats and transferred to the civet cat which passed it on to humans.Queues have been growing at hospitals in Wuhan
This new virus also causes severe acute respiratory infection.Symptoms seem to start with a fever, followed by a dry cough and then, after a week, lead to shortness of breath and some patients needing hospital treatment.
Based on early information, it is believed that only a quarter of infected cases are "severe", and the dead are mostly - though not exclusively - older people, some of whom have pre-existing conditions.The Chinese authorities suspect a seafood market that "conducted illegal transactions of wild animals" was the source of the outbreak.
Why is there concern about containing the virus? Scientists at the respected MRC Centre for Global Infectious Disease Analysis in the UK have warned that it may not be possible to contain the virus to China.They say self-sustaining human-to-human transmission of the coronavirus is the "only plausible explanation" for the scale of the epidemic.Their calculations estimate each infected person is passing it onto, on average, 2.5 other people.The centre praised the efforts of the Chinese authorities, but said transmission of the virus needed to be cut by 60% in order to get on top of the outbreak.
The coronavirus has killed at least 56 people
This is a massive challenge, the scientists suggest, which will require finding and isolating even patients with only mild symptoms that could easily be confused with other diseases.
Elsewhere, a team at Lancaster University have published their estimates of the number of cases suggesting 11,000 have been infected this year. If true, that would be more than Sars.
Where has it spread?
There are now 1,372 confirmed cases across China, though most are concentrated in those provinces closest to Hubei.
But it has also spread abroad - in isolated cases affecting small numbers of patients.
On Saturday, Australia confirmed its first four cases - first in Melbourne, and then three more in Sydney.
It has also spread to Europe, with three cases confirmed in France. Tests in the UK on 31 people have come back negative, the government has said. Officials are trying to trace around 2,000 people who have recently flown to the UK from Hubei province.

The cases largely involve people who had recently travelled from the affected region in China.
China's neighbours in the Asia region are on high alert, however, with cases reported in Thailand, Singapore, Japan, Taiwan, Malaysia, Vietnam, South Korea and Nepal.
There are also two cases in the United States, including a woman in her 60s who had returned home to Chicago from Wuhan on 13 January.
Canada has a "presumptive case" of the virus, but the condition of the person suffering from it is deemed stable, according to a government statement.
What's happening at the source?
The city of Wuhan is effectively on lockdown, with heavy restrictions on travel in and out, and public transport options from buses to planes cancelled.
It is a major population centre with up to 11 million inhabitants - comparable in size to London.
Pharmacies in the city have begun to run out of supplies and hospitals have been filled with nervous members of the public.
Officials have urged people to avoid crowds and gatherings.
"The whole transport system has been shut down," Kathleen Bell, who is is originally from the UK and works in Wuhan, told the BBC. "From midnight tonight private cars are not allowed on the road. And taxis aren't running."

As public health concerns rise over a new virus, the impact is being felt by China's travel and tourism sector.
More than 400m Chinese were expected to travel over the Lunar New Year which starts today, normally one of the busiest periods for airlines, hotels and tourist attractions.
Instead, flights and hotels are being cancelled as people face travel restrictions or choose to stay home.
The virus has already taken 25 lives, with more than 800 cases globally.
Many airlines have agreed to refund fares or let passengers rebook free of charge if affected, while major hotel chains are now following suit as more travel restrictions are announced.
After the Civil Aviation Administration of China announced that airlines should give refunds for cancelled flights, the country's three major airlines, China Southern Airlines, China Eastern Airlines and China Air all saw their share prices take a dive. China Eastern Airlines has seen its value fall about 13% this week.

Hong Kong's national carrier Cathay Pacific was among the first airlines to allow passengers scheduled to fly to or from Wuhan to reschedule for free while, at the same time, allowing cabin crew to wear surgical masks on flights.
Wuhan is where the first cases in the outbreak were reported. The flu-like virus has since spread to several our parts of China and internationally with cases being confirmed in Singapore, Thailand and the US among others countries.
China's biggest online travel agency, Trip.com, is also waiving cancellation fees on all hotels, car rentals and tickets for tourist attractions to Wuhan and is ''actively monitoring the situation to ensure the safety of all travellers''.
Hotels and casinos hit
Hotel groups are also paying out refunds to tourists who want to cancel trips to Wuhan and other parts of China.
Both InterContinental Hotels Group (IHG) and Hyatt will allow guests to change or cancel stays at the majority of their Chinese hotels over the Lunar New Year holiday. IHG has 443 hotels in China, Hong Kong, Macau and Taiwan under different brands, with four in Wuhan.
Casino operators have also seen shares fall, particularly those with businesses in Macau. The city is home to casinos owned by Las Vegas Sands and Wynn Resorts.
The release of seven movies over the Lunar New Year has also been postponed.
Blow to economy
Tourism has become an increasingly important part of the Chinese economy and is estimated to contribute about 11% of China's economic growth and employ about 28 million people.
In 2018, 62.9 million tourists visited China, ranking it the fourth most popular tourist destination behind France, Spain and the US, according to the UN's World Tourism Rankings.
Outside of China, luxury goods brands are also likely to take a battering as Chinese tourists stay at home rather than travel overseas for shopping sprees. LVMH, which owns the Burberry, Louis Vuitton and Hermes brands, saw its value slide this week.

Outbound trains in Wuhan have been stopped
There have been widely-shared reports on social media and some state-run services that healthcare services in Wuhan - one of China's largest cities - are under strain following the outbreak of coronavirus.
Hu Xijin, the editor of state-run newspaper Global Times, said there had been a "failure" to contain the virus, and videos of patients queuing to get seen in hospitals.
However, other Communist-party outlets have praised the response to the outbreak.
Wuhan is a major transit hub with a population of about 11 million people, and has effectively been put on lockdown, along with other major cities in the region, in an unprecedented move to stop the spread of the virus.
Can healthcare in Wuhan cope?
The city serves as the main economic hub for the wider province, Hubei, and has the most advanced healthcare facilities in the region.
The metropolitan area has seven major hospitals - considered some of the best in China, with Tong Ji Hospital ranked third nationally - treating patients.
It has seven more hospitals supporting the efforts, and 61 clinics around the city which are testing patients for symptoms of the virus.
A local government report from 2014 included Wuhan among the top six cities for medical treatment in the country - although it ranks behind Beijing and Shanghai.
In terms of capacity, the report said Wuhan had 6.51 hospital beds and 3.08 doctors per 1,000 people - this isn't a straightforward indication of healthcare capacity (more doctors doesn't always mean better healthcare), but it does rank Wuhan among the more developed places in the world. The UK and US have 2.8 and 2.6 doctors per 1,000 heads, respectively.

So - is is this enough for a such a large city undergoing a mass shutdown?
The lockdown in Wuhan has caused panic in the city - the World Health Organization (WHO) has said that containing a large city like this is "new to science".
We haven't been able to independently verify these claims.
So the question is - can you quarantine an entire city? And if you can - does it work?
Gauden Galea, the World Health Organization's representative in China, puts it more bluntly.
The problem, the professor says, is many people could have the virus and not even know it.
"There is a difference between infected and infectious," he warns.
So overall, is the Wuhan shutdown worthwhile?
"China has only been reporting confirmed cases," says Prof Kamradt-Scott.
Another death was later confirmed in north-east Heilongjiang province.
The province borders Russia and is more than 2,000 kilometres (1,200 miles) from Wuhan.

Analysis - Can the coronavirus be stopped?
We now know this is not a virus that will burn out on its own and disappear.
Only the decisions being made in China - including shutting down cities - can stop it spreading.
Scientists have revealed each infected person is passing the virus onto between 1.4 and 2.5 people.
It is known as the virus's basic reproduction number - anything higher than 1.0 means it's self-sustaining.
Those figures are early estimates, but put coronavirus in roughly the same league as Sars. There are two crucial outstanding questions - who is infectious and when are they infectious.
The fact only 25% of reported cases are severe is a mixed blessing.
Yes, that is less dangerous than Sars, but if those hard-to-detect mild or maybe symptomless cases are contagious too, then it is much harder to contain.
And we still don't know when people are contagious. Is it before symptoms appear, or only after severe symptoms emerge? One is significantly harder to stop spreading than the other.
The impact of the coronavirus is not limited to Hubei province. Authorities have also shut major tourist sites including the Forbidden City in Beijing and a section of the Great Wall and cancelled major public events in other parts of the country, including:
Traditional temple fairs in Beijing
An international carnival in Hong Kong
Hong Kong's annual football tournament
All public Lunar New Year celebrations in Macau
Shanghai's Disney Resort is temporarily closing, as are McDonald's in five cities.
Media captionWHO regional director says China now has "stronger capacity" to deal with infectious outbreaks
Earlier, information from China's National Health Commission, when the death toll was 17, said the youngest person who died from the virus was 48 and the oldest was 89.
Most victims were elderly and suffered from other chronic diseases including Parkinson's and diabetes.

The project will "solve the shortage of existing medical resources" and would be "built fast [and] not cost much... because it will be prefabricated buildings".
Media captionWhat are viruses? And how do they spread?
Videos have been circulating on social media, reportedly taken by Wuhan residents, showing long queues at local hospitals.
In one video on Twitter taken from Chinese social media, a man can be heard complaining, saying patients could be queuing for as long as 10 hours. The video could not be independently verified by the BBC.

The World Health Organization has not classed the virus as an "international emergency", partly because of the low number of overseas cases.
"It may yet become one," said the WHO's director-general, Dr Tedros Adhanom Ghebreyesus.

How are people coping in the lockdown?
One doctor, who requested anonymity, describes the conditions at a hospital in Wuhan.
"In the last two weeks, there has been an alarming rate of spread," she told the BBC. "The hospitals have been flooding with patients, there are thousands, I haven't seen so many before."
One woman, Jane, flew back to Wuhan from Beijing just before the lockdown.
"I feel very uneasy," she said. "But for me, because my child, my husband and family… are in the Wuhan area, I have to go back."
Daniel Pekarek, a software engineering student at Wuhan University, told the BBC he and his friends were all staying in their rooms.
"I was planning to stay in my apartment because I'm scared to go to the gym, and I'm scared to go to out in public, and not many people are willing to go out."

What's the global situation?
Vietnam and Singapore were on Thursday added to the nations recording confirmed cases, joining Thailand, the US, Taiwan and South Korea.
Japan and South Korea have both confirmed their second cases.
On Friday, Singapore confirmed its third case - who is known to be the son of another patient. Thailand has five.
Other nations are investigating suspected cases, including the UK, US, and Canada.
Many authorities have announced screening measures for passengers from China, including on Thursday the major airport hubs of Dubai and Abu Dhabi.
Taiwan has banned people arriving from Wuhan and the US state department warned American travellers to exercise increased caution in China.
