A week-long rapid construction of two hospitals in Wuhan will be complete by next week and will start taking in coronavirus patients, state media CGTN said on Saturday, citing the mayor of Wuhan.

One 1000-bed hospital will admit patients from Feb. 3, while another 1,500-bed hospital will take in patients from Feb. 6.

Wuhan — the epicenter of the outbreak — started rapid construction on those hospitals from just a week ago, a process that was watched by millions of viewers via live-streaming.

Meanwhile, local railway security has been told to step up epidemic control measures to stem the spread of coronavirus during the holiday season travel rush, according to state media People’s Daily.

These are the airlines which have suspended all flights to China amid the outbreak: American Airlines (until March 27), Delta Airlines (Feb 6. to April 30), Air France (until Feb. 9), British Airways, Air Seoul, Egyptair, Lion Air, Lufthansa, Swiss Airlines and Austrian Airlines (until end February), Kenya Airways, RwandAir (till further notice), Vietjet (effective Feb. 1), all Russian airlines (except Aeroflot).

Airlines which suspended some flights, or reduced capacity:

– United Airlines: suspending flights from its hubs to Beijing, Shanghai and Chengdu from Feb. 6 to March 28.

– Air New Zealand: reduced flights between Auckland and Shanghai to four return services a week from Feb. 18 to March 31, from the daily frequency.

Mask manufacturers in some Chinese cities resumed the production of masks, even as many provinces have delayed the start of work. 17 companies in Shanghai and 30 others in Jiangxi have started work manufacturing masks, according to state media People’s Daily and CGTN on Saturday morning.

Meanwhile, overseas Chinese have donated over one million masks, according to People’s Daily citing a Fujian official.

More provinces or municipalities in China announced a delay to the start of work or school.

Beijing announced that companies in the city will have to find ways to work remotely till Feb. 10 to stem the coronavirus outbreak — except essential industries, according to state media Beijing Daily.

Tianjin announced Saturday morning that businesses and schools are not to reopen until further notice, while Hunan said work must resume no earlier than midnight on Feb. 9, as did Xi’an city.

Other provinces and cities have delayed the start of work. Hubei authorities have announced that businesses are not to resume work till midnight on Feb. 13. Shanghai, Chongqing, Anhui, Fujian, Guangdong, Jiangsu, Jiangxi, Yunnan, Suzhou, Inner Mongolia and Zhejiang told businesses not to resume work till midnight on Feb. 9.

However, on Friday, China officials said that Hubei would further extend the holiday to an “appropriate extent,” reported the state-owned People’s Daily. Hubei residents who work outside the province were also asked to stay put.

China has flown home a total of 310 Hubei residents from Bangkok, Thailand, Kota Kinabalu in Malaysia and Tokyo in Japan, according to state media CGTN.

That’s in view of the “practical difficulties” that residents in Hubei — the epicenter of the outbreak — have been encountering overseas, officials said previously.

Spain confirmed the country’s first case of coronavirus after a man was diagnosed on the island of La Gomera in the Canaries, according to a Reuters report citing the country’s Health Ministry.

China’s National Health Commission said there have been an additional 46 deaths and 2,102 new confirmed cases, as of the end of Friday. That brings the country’s total to 259 deaths and 11,791 confirmed cases, the government said.

Hubei Province’s local health commission reported 45 new deaths from the outbreak on Friday, bringing the total to 249. The province confirmed 1,347 new cases of infection on Friday, with the total reaching 7,153 by the end of the day.

The Trump administration is issuing a mandatory quarantine for U.S. citizens who’ve visited Hubei province in the last 14 days and denying entry to foreign nationals who “pose a risk of transmitting” the virus in the U.S., administration officials said in declaring the coronavirus a public health emergency. “Any US citizen returning to the United States who has been in the Hubei province in the previous 14 days will be subject to up to 14 days of mandatory quarantine to ensure they’re provided proper medical care and health screening,” Health and Human Services Secretary Alex Azar said.

Sweden’s Public Health Agency said a woman tested positive for coronavirus and was being kept isolated at a hospital in southern Sweden, the country’s first confirmed case. The woman visited Wuhan and experienced symptoms after her return to Sweden, the agency said.

Delta Air Lines and American Airlines are planning to suspend their already reduced service to China as the rapid spread of coronavirus hurts demand to the country for airlines around the world. Delta said its China service suspension will begin Feb. 6 and last through April 30, but it will continue to operate the service until then to “ensure customers looking to exit China have options to do so.” Dozens of carriers including United, Cathay Pacific, British Airways and others have slashed or suspended service to China because of the outbreak. Delta was the first in the U.S. to suspend service altogether.

Italy declared a six-month state of emergency after two Chinese tourists in the country tested positive for the coronavirus in the first cases detected in the country. The move will enable authorities to make rapid decisions if needed. Italy has already banned all flights to and from China. The two patients came from Wuhan, the epicenter of the virus, and fell ill during their trip to Italy.

Singapore’s health ministry banned entry to all Chinese visitors and foreigners with a recent history of travel to China. The move, which effectively shuts out the island’s largest group of visitors, takes effect Saturday. It is the first Southeast Asian country to implement a travel ban for China travelers to contain the outbreak. The announcement came after the U.S. State Department raised its travel advisory on Thursday for China from Level 3 to Level 4. Mongolia also said it’s closing all ports of entry to and from China, giving citizens until Feb. 6 to get home.
