BEIJING — A second case of coronavirus was confirmed Friday, Jan. 24, in the United States, as China's efforts to control its outbreak expanded on many fronts. Travel bans were extended in central China to put tens of millions of people effectively on local lockdowns. In Wuhan, where the virus was first detected, workers are racing to build a 1,000-bed hospital to treat victims of the disease.
U.S. officials said Friday they are assessing the extent and duration of screening travelers from Wuhan at San Francisco, Los Angeles, New York's John F. Kennedy, Atlanta and Chicago's O'Hare international airports. The lockdown in the central Chinese city of Wuhan, where the outbreak began, and nearby cities means fewer travelers from there are arriving in the United States.
The labor-intensive airport screening is being conducted by the Centers for Disease Control and Prevention (CDC). But sick patients with no symptoms might not be detected.
To control the spread of the coronavirus, resources also need to be focused at the state and local levels, where front-line health officials are trying to rapidly identify cases, said Martin Cetron, director of CDC's division of global migration and quarantine.
Meanwhile, authorities around China, including in the capital, Beijing, have canceled the temple fairs and festivals that accompany the Spring Festival to avoid having large public gatherings where the airborne virus could spread.
A young, healthy man from Wuhan and a person living 1,500 miles from the epicenter of the coronavirus are among the latest victims of the outbreak, which has incited fear and anger across China as the important Spring Festival gets underway.
Reports of eight new deaths from the pneumonia-like virus, taking the total to 26, came as authorities enforced a lockdown across large parts of the province of Hubei, population 59 million. But they also came as the medical system clearly struggled to cope with the outbreak, with reports of crowded hospitals, stressed doctors and dwindling supplies.
Adding to the stress, Friday marked the official start of the Spring Festival, when China celebrates the arrival of the new lunar year. Authorities around the country, including in the capital, Beijing, have canceled the temple fairs and festivals that accompany the holiday to avoid having large public gatherings where the airborne virus could spread.
"The public should not gather during the Spring Festival and try stay at home as much as possible to protect themselves," Gao Fu, a member of the expert group of the National Health and Health Commission and director of the Chinese Center for Disease Control and Prevention, said Friday.
He encouraged everyone to wear masks, and photos from train stations and airports across the country showed people with their mouths and noses covered.
The Beijing Capital International Airport was unusually empty on Friday, with almost all passengers wearing masks. The Beijing city government and Shanghai local authorities have also urged residents returning to areas affected by the virus, or who have been in contact with suspected cases, to stay at home or in a centralized quarantine area for 14 days to contain the spread.
The state broadcaster, CCTV, led its midday news program with a report about a huge Spring Festival banquet in Beijing attended by President Xi Jinping and other Communist Party leaders. None of them were wearing masks, and the report made no mention of the virus outbreak.
The National Health Commission reported Friday that there are now more than 830 confirmed cases of infection, and reports of new cases continued to roll in from around the country: from Xinjiang in the west to Shandong in the east, from Inner Mongolia in the north to Hainan in the south.
A total of 8,420 people were reported to be under observation.
Amid increasing talk that the real number of deaths and infections could be much higher than the official figures, the State Council, the Chinese equivalent of the cabinet, vowed to "seriously handle" underreporting of cases.
The virus nevertheless continues to spread, including outside China's borders.
South Korean authorities confirmed Friday that a second person has tested positive for the new coronavirus. The 55-year-old South Korean man had been living in Wuhan and had landed at Gimpo Airport in Seoul on a flight from Shanghai. He is now hospitalized.
Japan also confirmed a second case, a man in his 40s from Wuhan who arrived in Japan on Sunday on a flight through Hong Kong. He is currently being treated, the Health Ministry said.
Other countries that have reported infections include Thailand, Singapore, Vietnam and the United States. In addition to a confirmed case in Washington state, Texas has reported a potential case of coronavirus in Brazos County, about 100 miles northwest of Houston.
The patient there contracted a respiratory illness within two weeks of traveling in Wuhan and is being isolated at home, the Centers for Disease Control and Prevention said.
While the World Health Organization has still not declared the outbreak a public health emergency of international concern, Director General Tedros Adhanom Ghebreyesus said Thursday that it still amounts to "an emergency in China."
"It has not yet become a global health emergency, but it may become one," he said.
Some details about the latest deaths in China have raised concerns about the virus's spread.
Until now, the vast majority of the victims had been older than 60, and almost all of them had existing health conditions. All had been in Hubei province and especially in its capital, Wuhan.
But the latest announcement said that a 36-year-old man from Wuhan, identified only by his family name, Li, died on Thursday. He had no chronic diseases or other existing health conditions, and had been treated with anti-virus medication and antibiotics since being admitted to a hospital on Jan. 9.
Another death occurred in Suihua in Heilongjiang province, near the border with Russia and some 1,500 miles from Wuhan.
New travel restrictions were put in place Friday to try to curb transmission of the virus.
Wuhan shut down tunnels under the Yangtze River to stop the flow of traffic. That comes in addition to travel bans imposed on Wuhan and seven other areas in Hubei province Thursday, with trains and buses canceled and highways closed.
All ride-hailing services in Wuhan were cut off from midday Friday in attempt to stop transmission of the virus, and only half of taxis are allowed on the road every day, alternating between tags ending in odd and even numbers.
China Southern, the country's biggest airline, had already canceled all flights in and out of Wuhan airport on Thursday. The other two main carriers, Air China and China Eastern, said they would cancel all Wuhan flights from Friday to at least Feb. 8.
Authorities are taking extreme measures to stop the large public gatherings that are a hallmark of the Spring Festival, which is often the only time of year that families can come together, much like Thanksgiving in the United States.
New year festivals and temple fairs around the country have been canceled, and the Forbidden City in Beijing, which can admit 80,000 people a day and was already entirely sold out for the holiday, has been closed until further notice.
Production companies have postponed the release of seven blockbuster films that were to be released over the holiday, prompting Chinese cinema companies to close the country's 70,000 movie theaters.
Schools in Hubei province, due to begin the spring semester after the holiday, will not open their doors as planned but will wait for further guidance from health authorities. And the Education Ministry instructed universities around China to delay their opening dates if necessary.
