China and countries around the world are scrambling to contain the spread of a new coronavirus that has killed 81 people and infected more than 2,700.

More than 56 million people in almost 20 Chinese cities - including Wuhan, capital of Hubei Province where the virus originated - have been under a strict lockdown, introduced amid fears the transmission rate will balloon as hundreds of millions of Chinese travel during Lunar New Year celebrations.

US State Department warns against visiting China

The US State Department warned against visiting China and said Americans should not travel to the Hubei province, given the city of Wuhan is ground zero for the deadly coronavirus.

The department already ordered the departure of all non-emergency US personnel and family members from the province and said the "US government has limited ability to provide emergency services" to its citizens there.

It said travellers should be prepared for the Chinese government to put travel restrictions in place "with little or no advance notice".

Trump: US, China in close contact on outbreak

US President Donald Trump said the United States and China were in close contact over the deadly coronavirus outbreak, which has infected thousands in more than 10 countries and killed at least 81.

US stocks follow global markets lower over virus concerns

US stocks tumbled following a sell-off in markets in Europe and Japan after China announced a sharp rise in cases of a deadly new virus that threatens to crimp global economic growth.

Every major US index gave up a significant amount of their gains for January and bond yields moved lower as investors headed for safer holdings. Airlines, resorts and other companies that rely on travel and tourism suffered steep losses. Gold prices rose.

Investors are in a "sell first, ask questions later situation", said Alec Young, managing director of global markets research at FTSE Russell.

WHO corrects China virus global risk level to 'high'

The World Health Organization on Monday admitted an error in its assessment of the global risk of a deadly virus in China, saying it was "high" and not "moderate".

The Geneva-based UN health agency said in a situation report published late Sunday that the risk was "very high in China, high at the regional level and high at the global level."

In a footnote, the WHO explained it stated "incorrectly" in its previous reports on Thursday, Friday and Saturday that the global risk was "moderate".

The correction of the global risk assessment does not mean an international health emergency has been declared.

Wuhan mayor willing to resign if it helps contain virus

The mayor of the Chinese city where a deadly virus broke out said he would be willing to resign if it helps the government contain its spread.

Mayor Zhou Xianwang told state broadcaster CCTV both he and Wuhan's Communist Party secretary are willing to take responsibility for closing off the city, including being removed from office.

As the virus spread through China and overseas, transportation links to the city were cut last week to prevent more people from leaving.

Zhou also responded to allegations that the city was slow to disclose information in the early days of the outbreak, saying local governments are restricted from releasing information about infectious diseases without authorisation.

He told state broadcaster CCTV the city's management of the crisis was "not good enough" - rare public self-criticism for a Chinese official.
