China's National Health Commission said at least 26 people have died from a fast-spreading coronavirus, as the total number of confirmed cases in the country rose to 830.
Some 33 million people in China are now under travel restrictions. Shanghai Disney is closing until further notice at a time when the Walt Disney theme park would normally be packed with tourists during Saturday's Lunar New Year holiday.
The deadly pneumonia-like virus was first identified on Dec. 31 in the Chinese city of Wuhan in Hubei province. It has since spread beyond Wuhan, which has a population of 11 million, to other major cities such as Beijing, Shanghai, Macao and Hong Kong.
China's Finance Ministry said it has allocated 1 billion yuan ($145 million) to support Hubei province in its fight to contain the outbreak.
The city of Wuhan is also building a 1,000-bed hospital to treat the infected and plans to have the facility operational by early next week, Reuters reported, citing state media.
Multiple cases of the virus have been confirmed in Thailand, Vietnam, South Korea and Japan, while the United States, Taiwan and Singapore have each reported one case.
The virus, named the "2019-nCoV," belongs to a family of viruses known as coronaviruses, which can be transmitted from person to person.
The World Health Organization on Thursday said at a press conference the outbreak did not yet constitute a global public health emergency.
"Make no mistake, this is, though, an emergency in China. But, it has not yet become a global health emergency. It may yet become one," said Tedros Adhanom Ghebreyesus, director-general of the WHO. He added the organization's assessment is that "the outbreak is very high-risk in China, and high-risk regionally and globally."
As of Friday, 10 cities with a total population of about 33 million were put under lockdown measures. Transportation services in Wuhan, the epicenter of the virus, were shut down on Jan. 23 and people were asked to not leave. The airport and train station in the city of 11 million residents were also temporarily closed.
Other cities under lockdown include Huanggang, Xiantao, Ezhou, Qianjiang, Zhijiang, Chibi and Lichuan. Authorities have also canceled Lunar New Year events in Beijing and other places. Airlines and rail operators are offering refunds on domestic flights and train tickets around the country.
The virus outbreak is most frequently compared to the spread of SARS, or severe acute respiratory syndrome, between 2002 and 2003, when more than 8,000 people were infected. Around 800 people died in that crisis, according to the WHO.
