China faced deepening isolation over its coronavirus epidemic as the death toll soared to 290, with the United States and Australia leading a growing list of nations to impose extraordinary Chinese travel bans.
With Britain, Russia and Sweden among the countries confirming their first infections, the virus has now spread to more than two dozen nations, sending governments scurrying to limit their exposure.
China toughened its own quarantine measures at the centre of the outbreak in Hubei province, a day after the United States temporarily barred entry to foreigners who had been in China within the past two weeks.
"Foreign nationals, other than immediate family of US citizens and permanent residents... will be denied entry into the United States," Health Secretary Alex Azar said.
Australia said it was barring entry to non-citizens arriving from China, while Australian citizens who had travelled there would be required to go into "self-isolation" for two weeks.
Vietnam suspended all flights from mainland China effective yesterday, while Russia announced it would halt visa-free tourism for Chinese nationals and stop issuing them work visas.
Similar expansive restrictions have been announced by countries including Italy, Singapore, and China's northern neighbour Mongolia.

WHO declares public health emergency over coronavirus outbreak
Ireland, US, Japan, Britain, Germany and other nations had already advised their citizens not to travel to China.
Thousands of Hong Kong medical workers voted to commence a four-day strike from Monday to push the government to close its border with mainland China to stop the virus, which has already spread to the financial hub.
Britain said it was temporarily withdrawing some diplomatic staff and their families from across China, a day after the US State Department ordered embassy employees to send home family members under the age of 21.
Beijing insists it can contain the virus and called Washington's advice against travel to China "unkind".
"Certainly it is not a gesture of goodwill," foreign ministry spokeswoman Hua Chunying said.
The US emergency declaration also requires Americans returning from Hubei province to be placed in mandatory 14-day quarantine, and health screening for American citizens coming from other parts of China.
The virus emerged in early December and has been traced to a market in Hubei's capital Wuhan that sold wild animals.
It spread globally on the wings of a Lunar New Year holiday rush that sees hundreds of millions of Chinese people travel domestically and overseas.
The economic fallout continued Saturday as Apple announced that all its China stores would be closed until 9 February.
China's central bank said it would offer financial support to businesses hit by the public health emergency.
With public anger mounting in China, Wuhan's top official admitted late Friday that authorities there had acted too slowly.
"If strict control measures had been taken earlier the result would have been better than now," said Ma Guoqiang, the Communist Party chief for Wuhan.
Wuhan officials have been criticised online for withholding information about the outbreak until late December despite knowing of it weeks earlier.
China finally lurched into action last week, effectively quarantining whole cities in Hubei and tens of millions of people.
Unprecedented safeguards imposed nationwide include postponing the return to school, cutting bus and train routes, and tightening health screening on travellers nationwide.
Today, authorities in Hubei extended the new year holiday until 13 February and announced a suspension of marriage registrations from Monday to discourage public gatherings.
The city of Huanggang, east of Wuhan, said only one member of each household would be permitted to leave the house every two days to buy necessities.
But the toll keeps mounting at an ever-increasing pace, with health authorities on Saturday saying 46 more people had died in the preceding 24 hours, all but one in Hubei.
Another 2,102 new infections were also confirmed, bringing the total to nearly 12,000 -- far higher than the Severe Acute Respiratory Syndrome outbreak of 2002-03.
SARS, which is caused by a pathogen similar to the new coronavirus and also originated in China, killed 774 people worldwide -- most of them in mainland China and Hong Kong.
The World Health Organization (WHO) declared the outbreak a global emergency on Thursday but later warned that closing borders was probably ineffective in halting transmission and could accelerate the virus's spread.
But authorities around the world pressed ahead with preventive measures.
Thai health officials on Friday said a taxi driver became the kingdom's first case of human-to-human transmission.
Thailand joins China, Vietnam, Germany, Japan, France and the United States with confirmed domestic infections.
The health crisis has dented China's international image and put Chinese nationals in difficult positions abroad, with complaints of racism.
More than 40,000 workers at a vast Chinese-controlled industrial park in Indonesia -- which also employs 5,000 staff from China -- were put under quarantine, the facility said on Friday.
On the same day, China flew overseas Hubei residents back to the centre of the outbreak in Wuhan on chartered planes from Thailand and Malaysia, citing "practical difficulties" the passengers had encountered overseas.
Countries have scrambled to evacuate their nationals from Wuhan, with hundreds of US, Japanese, British, French, German, South Korean, Indian, Bangladeshi and Mongolian citizens evacuated so far, and more governments planning airlifts.
China urges no weddings, short funerals to contain virus
China has asked couples to delay their nuptials from a popular wedding date and families to scale down funeral services to help slow the spread of the virus.
"Where marriage registrations have been announced or promised for February 2 this year, you are advised to cancel it and explain the situation to others," a civil affairs ministry statement said.
2 February this year is being considered a lucky date for wedding ceremonies because the sequence of numbers "02022020" reads the same backwards as forwards.
Beijing, Shanghai and other cities had earlier decided to offer wedding registry services on the date, despite it falling on a Sunday when offices are usually closed.
The ministry said it would temporarily halt marriage counselling services and asked the public not to hold wedding banquets.
It also said funerals should be held in a "simple and expeditious manner to avoid gatherings of people" and the bodies of any victims of the coronavirus should be cremated as soon as possible.
Staff handling funerals should wear protective gear and carry out temperature checks to avoid risking infection, the statement added.
York student confirmed as having coronavirus
One of the two people who have tested positive for coronavirus in the UK is a student at the University of York, a university spokesman said.
The pair - two members of the same family - are being treated at a specialist unit in Newcastle.
They had checked in to the Staycity apartment-hotel in York on Wednesday and were taken to hospital that evening.
A spokesman for the university said Public Health England has advised university officials that the risk of infection being passed on campus is "low".
"Public Health England has advised us that the risk of infection being passed to others on campus is low. Current information from PHE suggests that the student did not come into contact with anybody on campus whilst they had symptoms, but investigations are ongoing to fully establish this.
"Our immediate concerns are for the affected student and family, along with the health and continued wellbeing of our staff, students and visitors," the spokesman said.
