WUHAN, China — The Chinese authorities resorted to increasingly extreme measures in Wuhan on Thursday to try to halt the spread of the deadly coronavirus, ordering house-to-house searches, rounding up the sick and warehousing them in enormous quarantine centers.
The urgent, seemingly improvised steps come amid a worsening humanitarian crisis in Wuhan, one exacerbated by tactics that have left this city of 11 million with a death rate from the coronavirus of 4.1 percent as of Thursday — staggeringly higher than the rest of the country’s rate of 0.17 percent.
With the sick being herded into makeshift quarantine camps, with minimal medical care, a growing sense of abandonment and fear has taken hold in Wuhan, fueling the sense that the city and surrounding province of Hubei are being sacrificed for the greater good of China.
The harsh new moves in Wuhan, the epicenter of the outbreak, clearly signaled the ruling Communist Party’s alarm that it had failed to gain control of the coronavirus epidemic, which has overwhelmed the country’s health care system and threatened to paralyze China, the world’s most populous country and second-largest economy.
The steps were announced by the top official leading the country’s response to the virus, Vice Premier Sun Chunlan, as she visited Wuhan on Thursday. They evoked images of the emergency measures taken to combat the 1918 Spanish Flu pandemic that killed tens of millions people worldwide. Despite the severity of the new measures, however, they offered no guarantee of success.
The city and country face “wartime conditions,” Ms. Sun said. “There must be no deserters, or they will be nailed to the pillar of historical shame forever.”
Enforcing the new restrictions took on aspects of a military campaign as Ms. Sun ordered medical workers to mobilize into round-the-clock shifts to visit each home in Wuhan, check the temperature of all residents and interview close contacts of any infected patients.
Word of the new restrictions arrived as the people of Wuhan received an emotional gut punch from the news that a doctor who had warned of the outbreak in December — and was silenced by the police for it — had died from the coronavirus infection. The Wuhan City Central Hospital said in a posting on its social media account that its efforts to save the doctor, Li Wenliang, had failed.
“We deeply regret and mourn this,” the posting said.
Wuhan already had been basically shut down and isolated because of the contagion that began more than a month ago. The transportation lockdown has made it difficult to restock dwindling medical supplies for the province’s more than 50 million people, and has raised the possibility that food shortages may soon occur.
The new measures were announced two weeks after China barred people from leaving Wuhan, then expanded the restriction to cities in the central province of Hubei and now confines more than 50 million people — a containment of nearly unimaginable scope.

How is the United States being affected? There have been at least a dozen cases. American citizens and permanent residents who fly to the United States from China are now subject to a two-week quarantine.
What if I’m traveling? Several countries, including the United States, have discouraged travel to China, and several airlines have canceled flights.Many travelers have been left in limbo while looking to change or cancel bookings.
How do I keep myself and others safe? Washing your hands is the most important thing you can do.
Still, the number of confirmed infections has doubled roughly every four days, afflicting more Chinese cities and towns, and experts have questioned whether the government’s actions are imposing undue hardship on people while doing little to slow the epidemic.
As of Friday, government figures showed the virus had killed at least 636 people and infected at least 31,161, and many believe those official statistics are far from complete. The fatality rate for Hubei province as a whole was 2.8 percent as of Thursday.
The authorities have begun to direct patients in Wuhan to makeshift hospitals — including a sports stadium, an exhibition center and a building complex — that are intended to house thousands of people. Inspecting one of the centers, set up in Hongshan Stadium, Ms. Sun said that anyone requiring treatment should be rounded up, if necessary, and forced into quarantine.
“It must be cut off from the source,” she said of the virus, addressing city officials at the shelter, according to a Chinese news outlet, Modern Express. “You must keep a close eye. Don’t miss it.”
It was not clear how the already-strained facilities could handle an influx on the scale she seemed to suggest, or whether the new shelters were equipped or staffed to provide even basic care to patients and protect against spreading the virus.
Photos taken inside the stadium showed narrow rows of simple beds separated only by desks and chairs typically used in classrooms. Some comments on Chinese social media compared the scenes with those from the Spanish flu pandemic, the deadliest in modern history.
Mr. Xi did not make a public appearance on Thursday, apparently delegating the responsibility for the crisis to deputies, who all adopted the militaristic tone set by the People’s Daily this week when it described the campaign to contain the epidemic as a “people’s war.”
Even so, there were increasing signs that the restrictions on entering and leaving Hubei were slowing the resupply of medicines, protective masks and other necessities, despite pledges by Beijing and by private companies and charities that relief was en route.
“This is almost a humanitarian disaster, because there are not sufficient medical supplies,” said Willy Wo-Lap Lam, an adjunct professor at the Center for China Studies at the Chinese University of Hong Kong. “The Wuhan people seem to be left high and dry by themselves.”
Many medical experts believe that the number of those infected — and those who have died — is higher than the official count. Many Wuhan residents who are unwell but unsure whether they have the disease have been forced to go from hospital to hospital on foot, only to be turned away from even being tested for the virus, let alone treated.
Others wandered around in full protective clothing or with improvised safety measures, like plastic bags on their heads. Many have resorted to self-quarantine at home, risking the spread of the virus within families and neighborhoods.
Dr. William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center in Nashville, Tenn., said the challenges faced by the Chinese health authorities just managing the crisis in Wuhan were enormous.
“When both the physical and human resources for direct medical care are stretched, you’re going to have some unfortunate events and people will die,” he said. “You can’t manage that great a surge of patients for an extended period of time.”
But Dr. Schaffner also raised questions about the new steps, including risks to both coronavirus patients and their caregivers in makeshift quarantine shelters.
“What happens to the people who are sick?” he asked. “Do they receive care, and at what level? And can the caregivers, in the circumstances of a stadium or school auditorium, provide care effectively — and keep themselves safe?”
Other outside experts said that concentrating large numbers of sick people together in dormitory-like facilities created conditions ripe for inadvertently spreading a range of infectious diseases.
“A lot of these people already have underlying health problems that need to be cared for,” said Thomas M. File Jr., president of the Infectious Diseases Society of America. “You put them all in close proximity, and they could be exposed to other infections that are even more easily spread than coronavirus, like tuberculosis, which is airborne, and bacterial infections that can spread among dense populations.”
The epidemic has brought much of China to a virtual standstill, even far from Wuhan. Each day brings reports of more cities effectively sealed off, public events and gatherings canceled through February or beyond, and schools preparing to postpone their post-Lunar New Year reopenings.
The impact also has spilled across China’s borders, despite the government’s frenetic efforts to respond to the epidemic while publicly portraying it as a manageable crisis. Nearly 200 infections with the virus have been confirmed in about two dozen other countries and territories, and two of the patients outside China have died.
Other countries have stepped up their own efforts to quarantine patients, including those on two cruise ships. Global corporations that depend on China’s huge market and supply chains are scrambling to deal with disruptions caused by the coronavirus, acknowledging how much they have come to count on the Chinese economy.
In Wuhan, the first concern is the humanitarian plight of a city beginning its third week in a state of siege. The confusion caused by sweeping calls for action at the top and a chaotic situation on the ground indicated that the Chinese government had not yet gotten a handle on the crisis.
Wang Chen, a respiratory expert who is president of the Chinese Academy of Medical Sciences, said the new makeshift treatment sites had been designed to counter transmissions within households and neighborhoods.
“If a large number of patients with mild symptoms live at home or suspected patients roam around in the community, they will become the main source to spread the virus,” Mr. Wang said, according to the Xinhua news agency.
A widely shared post on Weibo, a popular social media site, said on Thursday that “conditions were very poor” at the Wuhan exhibition center that has been converted into a quarantine facility. The writer, who said he had relatives in the shelter, cited power failures and problems with heating, saying people had to “shiver in their sleep.”
The post said there appeared to be shortages of staff and equipment. “Doctors and nurses were not seen to be taking note of symptoms and distributing medicine,” it said, and oxygen devices were “seriously lacking.”
With public anger simmering, the Communist Party has moved to stifle news organizations and social media platforms where criticism of the government’s initial response were for a time left uncensored online.
The China Media Project, a watchdog group in partnership with the University of Hong Kong, published a directive from the Cyberspace Administration of China, which oversees the internet, accusing several social media companies of “illegally engaging in internet news information services in epidemic-related reports.”
It said some of the country’s giants, including Sina Weibo, Tencent and ByteDance, would be placed under special supervision to ensure “a favorable online environment for winning the war for prevention and control of the coronavirus outbreak.”
