China is putting on lockdown a city of 11 million people considered the epicentre of a new coronavirus outbreak that has killed 17 and infected nearly 600, China’s National Health Commission said.
The health authorities around the world are scrambling to prevent a global pandemic.
Health officials fear the transmission rate will accelerate as hundreds of millions of Chinese travel at home and abroad during week-long holidays for the Lunar New Year, which begins on Saturday.
The previously unknown virus strain is believed to have emerged late 2019 from illegally traded wildlife at an animal market in China’s central city of Wuhan.
The virus has been reported in other major cities, including Beijing, Shanghai and Hong Kong, and several other countries, including the US, stoking fears it is already spreading worldwide.
Wuhan’s city government said it would shut down all urban transport networks and suspend outgoing flights from 10am (0200 GMT) on Thursday, state media said.
Domestic media said some airlines were operating after the deadline, however.
State media broadcast images of one of Wuhan’s transport hubs, the Hankou rail station, nearly deserted, with gates blocked or barred.
The government is urging citizens not to leave the city.
State media reported highway toll booths around Wuhan were closing down, which would effectively cut off road exits.
Guards were patrolling major highways, one resident said.
As the city slipped into isolation, residents thronged into hospitals for checks and scrambled for supplies, clearing out supermarket shelves and queuing for petrol.
Authorities had confirmed 571 cases and 17 deaths by the end of Wednesday, China’s National Health Commission said.
Earlier, it said another 393 suspected cases had been reported.
Of eight known cases worldwide, Thailand has confirmed four, while Japan, South Korea, Taiwan and the US have reported one each.
In a report on Wednesday, Imperial College London said it estimated a total of 4,000 cases of the coronavirus in Wuhan alone as of January 18, an infection rate based on the number of cases reported in China and elsewhere.
Virus spreading in contrast with its secrecy over the 2002-2003 Severe Acute Respiratory Syndrome that killed nearly 800 people, China’s communist government has provided regular updates to avoid panic ahead of the holidays.
During a visit to Wuhan, Vice Premier Sun Chunlan said authorities needed to be open about the virus and efforts to contain it, the official said.
The World Health Organisation has said it will decide on Thursday whether to declare the outbreak a global health emergency, which would step up the international response.
If it does so, it will be the sixth international public health emergency to be declared in the last decade.
Some experts believe the new virus is not as dangerous as previous coronaviruses such as SARS and Middle East Respiratory Syndrome, which has killed more than 700 people since 2012.
“The early evidence at this stage would suggest it’s not as severe,” Australia’s Chief Medical Officer Brendan Murphy told reporters.
WHO Director-General Tedros Ghebreyesus said in Geneva that China’s actions were “very strong” but called on it to take “more and significant measures to limit or minimise the international spread”.
Ghebreyesus said: “We stressed to them that by having a strong action not only they will control the outbreak in their country but they will also minimise the chances of this outbreak spreading internationally.
“So they recognise that.”
In spite of China’s response, stock markets across Asia were on the back foot on Thursday, led by drops of roughly 1.5 per cent in Hong Kong and Shanghai while China’s yuan fell to a two-week low.
