China on Tuesday urged its citizens to postpone foreign travel to curb a viral outbreak that has killed 106 people, as the first cases of human-to-human contagion were detected abroad.

While a host of nations prepared to airlift their citizens from the epicentre of the epidemic, Japan and Germany reported the first cases that were not directly imported from China.
Until now, all cases in more than a dozen countries involved people who had been in or around Wuhan, the central Chinese city where the coronavirus first emerged in late December before infecting thousands of people nationwide.
On the other side of the world, a 33-year-old German man caught the disease from a Chinese colleague from Shanghai who visited Germany last week, according to health officials.
The development came after countries including Sri Lanka, Malaysia and the Philippines announced tighter visa restrictions for people coming from China.
Experts believe the virus came from a wild animal market in Wuhan and then jumped to humans, with Chinese health officials saying Tuesday that people infect each other through sneezing or coughing, and possibly through contact.
Authorities initially sealed off Wuhan and other cities in central Hubei province late last week, trapping more than 50 million people.
China then halted international and domestic group tours. It also imposed a wide range of travel restrictions inside China, suspending long-distance bus routes and more than 2,000 train services.
But with the death toll climbing and more fatalities reported in Chinese cities far away from Wuhan, authorities on Tuesday urged people to delay any foreign travel.
This was “to protect the health and safety of Chinese and foreign people,” the National Immigration Administration said.
The National Health Commission on Tuesday announced 26 new deaths — mostly elderly — bringing the nationwide total to 106.
The commission also said Tuesday that confirmed infections had nearly doubled from the previous day to 4,515, with another 7,000 cases suspected and awaiting confirmation.
Wuhan, meanwhile, has been turned into a near ghost-town under a lockdown that has largely confined the industrial hub’s 11 million people to their homes.
With a ban on car travel, the streets were nearly deserted apart from the occasional ambulance — although the city’s hospitals are overwhelmed.
“Everyone goes out wearing masks and they are worried about the infection,” said David, a Chinese man who works in Shanghai and ended up trapped in Wuhan after it went under quarantine.
Many thousands of foreigners are also among those trapped in the city.
Several foreign governments have drawn up plans to safely evacuate their citizens, but have faced major logistical and bureaucratic challenges.
Japan said it would send a chartered flight on Tuesday evening to get about a third of its 650 nationals there.
“We will also bring aid supplies such as masks and protective suits for Chinese people as well as for Japanese nationals,” Foreign Minister Toshimitsu Motegi said in Tokyo.
Motegi said the plane would leave Wuhan on Wednesday morning and that more flights may follow.
If the mission succeeds, Japan would be the first country to airlift its citizens out of Wuhan.
A US-chartered flight bound for California is scheduled to leave Wuhan on Wednesday with consular staff and some American citizens, a day later than previously planned.
France and South Korea are also planning to fly out their citizens later this week, and several other countries, including Germany, were considering doing so.
