HANGZHOU - Authorities in China warned they faced a severe shortage of hospital beds and equipment needed to treat a growing number of patients stricken by the new coronavirus, as the death toll rose to at least 560 on Thursday as cities far from the epicenter tightened their defenses.
The number of confirmed infections rose to at least 27,300 in an outbreak that has spiraled into a global health emergency with cases reported in more than 20 countries.
Among the cases was a newborn baby, diagnosed just 30 hours after being born.
Despite authorities building a hospital from scratch and converting public buildings to accommodate thousands of extra patients, there was still a "severe" lack of beds, said Hu Lishan, an official in Wuhan, the quarantined city where the virus first appeared -- and where doctors are now overwhelmed with cases.
There was also a shortage of "equipment and materials", he told reporters, adding that officials were looking to convert other hotels and schools in the city into treatment centers.
A growing number of cities have imposed a range of restrictions far from Hubei, as authorities battle to contain the virus.
Tens of millions of people, from the eastern industrial heartlands to near the northern border with Russia, have been told to stay indoors as authorities battle to curb the outbreak.
Global concerns have risen after the World Health Organization declared an international health emergency last week.
The WHO called for $675 million (613 million euros) in donations for a plan to fight the novel coronavirus, mainly through investment in countries considered particularly "at risk".
The Bill and Melinda Gates Foundation pledged to commit up to $100 million.
New cases emerged abroad, with 10 people testing positive for the virus on a cruise ship quarantined off the coast of Japan with thousands on board.
Also in Japan, the chief executive of the Tokyo Olympics set for later this year admitted organizers were "extremely worried" about how the virus could affect the Summer Games, but the International Olympic Committee urged calm.
Italy announced that passengers from every international flight would be scanned for fevers, while Vietnam joined a growing list of countries banning arrivals from China.
Hong Kong, which reported its first coronavirus death this week, said anyone arriving from the mainland would face a mandatory two-week quarantine from Saturday.
'DON'T GO OUT!'
In the city of Hangzhou, some 175 kilometers (110 miles) southwest of Shanghai, fences blocked streets near the headquarters of Chinese tech giant Alibaba -- one of the world's most valuable companies -- as a fighter jet circled overhead.
The building appeared to be shut down, while deliverymen moved in and out of nearby fenced-in residential areas to drop off groceries. Many people were also seen going out.
The firm is based in one of three Hangzhou districts subject to new restrictions that allow only one person per household to go outside every two days to buy necessities.
"Please don't go out. Don't go out. Don't go out!" blared a message on a loudspeaker urging people to wear masks, wash their hands regularly and report any people who are from Hubei -- reflecting a common fear that people from the province might infect others.
At least three other cities in Zhejiang province -- Taizhou, Wenzhou and parts of Ningbo -- have imposed the same measures, affecting 18 million people.
In the central city of Zhumadian, authorities said one person would be allowed to leave each household only every five days.
Residents of the city of seven million were also offered cash rewards for informing on people who came from neighboring Hubei province.
Authorities in Beijing said restaurants could no longer accept reservations for parties from Wednesday.
The disease is believed to have emerged in December in a Wuhan market that sold wild animals and spread rapidly as people traveled for the Lunar New Year holiday in January.
The Ministry of Public Security said "political security" was the "top priority" in confronting the epidemic.
The statement came days after the top leadership admitted "shortcomings" in its handling of the outbreak -- local authorities in Hubei have been criticized for initially downplaying the situation.
The death toll has steadily increased.
But officials have noted that the death rate, at around two percent, is well below the mortality rate of SARS, which killed some 800 people in 2002-2003.
Two fatalities have been reported outside the mainland, in Hong Kong and the Philippines.
Several governments have imposed travel restrictions while major airlines have suspended flights to and from China.
Thousands of Chinese tourists risked being stranded in Bali after the Indonesian government suspended flights to and from mainland China.
China has reacted angrily against travel bans, noting that the WHO does not advise imposing them.
It has accused the US of spreading "panic" in its response to the coronavirus, including its ban on Chinese travelers, and on Wednesday, it took another swipe at Washington.
"Panic is more deadly and contagious than any virus," foreign ministry spokeswoman Hua Chunying said at a press briefing.
