China sent medical workers and equipment to a newly built hospital, infused cash into financial markets and further restricted people’s movement in sweeping new steps on Monday to contain a rapidly spreading virus and its escalating impact.

China’s updated figures of 361 deaths and 2,829 new cases over the last 24 hours, bringing the Chinese total to 17,205 cases, come as other countries continued evacuating citizens from hardest-hit Hubei province and restricted travel by Chinese or people who recently traveled in the country.

The World Health Organization said the number of cases will keep growing because tests are pending on thousands of suspected cases.

Reopening of schools was also delayed to keep the virus from spreading further in Hubei, where the 1,000-bed hospital in the provincial capital Wuhan was completed in just 10 days. A second hospital with 1,500 beds will open within days. Restrictions were tightened still further in one city by allowing only one family member to venture out to buy supplies every other day.

Medical teams from the People’s Liberation Army were arriving in Wuhan to relieve overwhelmed health workers and to work at the new hospital, located in the countryside far from the city center. Its prefabricated wards, where patients began arriving by late morning, are equipped with state-of-the-art medical equipment and ventilation systems.

Leading Chinese epidemiologist Zhong Nanshan said additional hospital space was crucial to stopping the spread of new infections.

“The lack of hospital rooms forced sick people to return home, which is extremely dangerous. So having additional (beds) available is a great improvement,” Zhong told state broadcaster CCTV.

Zhong played a major role in overcoming China’s 2002-2003 outbreak of Sars, a coronavirus from the same family as the current pathogen.

In a sign of the economic toll of the outbreak, China’s Shanghai Composite index plunged 8.7% when it reopened on Monday following the Lunar New Year holiday. It steadied later on the central bank’s moves to inject cash.

“We are fully confident in and capable of minimizing the epidemic’s impact on economy,” said Lian Weiliang, deputy chief of the National Development and Reform Commission, at a news conference in Beijing.

In Hong Kong, thousands of health care workers were threatening to go on strike Tuesday unless the government agreed to talks before a 6pm Monday deadline. Hong Kong has recorded 14 cases of the virus and has cut flights and train and bus connections to the mainland, but a push is growing for the semi-autonomous Chinese city to close the border completely.

Strike organisers say about 6,000 medical staff were prepared to participate. Hong Kong was severely impacted by the Sars outbreak, which many believe was intensified by official Chinese secrecy and obfuscation.

South Korea, which has 15 confirmed cases, was quarantining 800 soldiers who had recently visited China, Hong Kong or Macao or had contact with people who had, defense ministry spokeswoman Choi Hyunsoo said. Military service is required of all young South Korean men to guard against the threat from the communist North.

In Beijing, officials sought to reassure the country’s 1.4 billion people of adequate supplies of face masks and disinfectant, despite reported shortages in parts of the country.

The Philippines banned the entry of all non-citizens from China after two cases were confirmed there, including the only death outside China. The US, Japan, Singapore, Indonesia, New Zealand and Australia have imposed similar restrictions despite criticism from China and WHO’s guidance that such measures were unnecessary.

About 150 cases have been reported in two dozen other countries. The Philippine Health Department said a 44-year-old Chinese man from Wuhan died from the virus and his companion remained hospitalised. Vietnam’s confirmed cases increased to eight, including a Vietnamese American man who had a two-hour layover in Wuhan on his way from the US to Ho Chi Minh City.

The US total rose to 11, mostly involving recent travel to Wuhan. The US said on Sunday that Americans who had traveled in China within the last 14 days would be routed to designated airports for enhanced health screenings and most non-Americans who recently were in China would be denied entry.

Amid accusations of a slow official response to the outbreak, six officials in the city of Huanggang, next to Wuhan in Hubei province, were fired over “poor performance” in handling the outbreak, the official Xinhua News Agency reported. It cited the mayor as saying the city’s “capabilities to treat the patients remained inadequate and there is a severe shortage in medical supplies such as protective suits and medical masks.”

The trading and manufacturing center of Wenzhou, with nearly 10 million people in coastal Zhejiang province, confined people to their homes, allowing only one family member to venture out every other day to buy necessary supplies. Huanggang, home to 7 million people, imposed similar measures on Saturday.
