The death toll from the coronavirus outbreak has risen to 170, and a confirmed case in Tibet means it has reached every region in mainland China.
Chinese health authorities said there were 7,711 confirmed cases in the country as of 29 January.
Infections have also spread to at least 15 other countries.
The World Health Organization (WHO) will meet on Thursday to again consider whether the virus constitutes a global health emergency.
“In the last few days the progress of the virus, especially in some countries, especially human-to-human transmission, worries us,” WHO Director-General Tedros Adhanom Ghebreyesus said on Wednesday.
He named Germany, Vietnam and Japan, where there have been cases of people catching the virus from others who have been to China.
“Although the numbers outside China are still relatively small, they hold the potential for a much larger outbreak,” the WHO chief said.
More people have now been infected in China than during the Sars outbreak in the early 2000s, but the death toll remains far lower. Sars, also a coronavirus, caused acute respiratory illness.
Researchers are racing to develop a vaccine to protect people from the virus. One lab in California has plans for a potential vaccine to enter human trials by June or July.
What’s the latest on evacuations?
Voluntary evacuations of hundreds of foreign nationals from Wuhan are under way to help people who want to leave the closed-off city and return to their countries.
The UK, Australia, South Korea, Singapore and New Zealand are expected to quarantine all evacuees for two weeks to monitor them for symptoms and avoid any contagion.
Australia plans to quarantine its evacuees on Christmas Island, 2,000km (1,200 miles) from the mainland in a detention centre that has been used to house asylum seekers.
Singapore is setting up a quarantine facility on Pulau Ubin, an island north-east of the city-state’s mainland.
In other developments:
- Flights to take British and South Korean citizens out of Wuhan have both been delayed after relevant permissions from the Chinese authorities did not come through
- Two flights to Japan have already landed at Tokyo’s Haneda airport and the passengers are being screened. Three have so far tested positive for the virus, Japanese media report
- Around 200 US citizens have been flown out of Wuhan and will be isolated at a military base in California for at least 72 hours
- Two aircraft are due to fly EU citizens home with 250 French nationals leaving on the first flight
- India has confirmed its first case of the virus – a student in the southern state of Kerala who was studying in Wuhan
How is China handling the outbreak?
Although questions have been raised about transparency, the WHO has praised China’s handling of the outbreak. President Xi Jinping has vowed to defeat what he called a “devil” virus.
The central province of Hubei, where nearly all deaths have occurred, is in a state of lockdown. The province of 60 million people is home to Wuhan, the heart of the outbreak.
The city has effectively been sealed off and China has put numerous transport restrictions in place to curb the spread of the virus.
People who have been in Hubei are also being told by their employers to work from home until it is considered safe for them to return.
The virus is affecting China’s economy, the world’s second-largest, with a growing number of countries advising their citizens to avoid all non-essential travel to the country.
Several international airlines have stopped or scaled back their routes to China and companies like Google, Ikea, Starbucks and Tesla have closed their shops or stopped operations.
There have been reports of food shortages in some places. State media says authorities are “stepping up efforts to ensure continuous supply and stable prices”.
The Chinese Football Association has announced the postponement of all games in the 2020 season.
What is the coronavirus?
The virus is thought to have emerged from illegally traded wildlife at a seafood market in Wuhan, where most cases and deaths have been reported.
But the earliest documented case, which has been traced back to 1 December, had no connection to the market.
Most of the confirmed cases involve people who are from Wuhan or had close contact with someone who had been there.
While there is no specific cure or vaccine for the virus, many people who contract it have only mild symptoms and do recover from it.
It can though cause severe acute respiratory infection and lead to death.
Like the similar Sars and influenza viruses, the new coronavirus is thought to be particularly a risk for elderly and people with pre-existing illnesses.
