Covid-19 Cases and Deaths: Live News Updates

“It’s the perfect environment for people to die in — which people are,” said Juan Moreno Haines, an inmate at San Quentin.

They needed help — fast — and the county responded: It sent in a “strike team” of medical workers, emergency responders, clergy and others, in what is becoming a new model for combating Covid-19 in residential care centers.

Nurses and doctors from hours away came to aid sick residents and replace staff who had contracted the virus. They set up oxygen and IV drips, to avoid sending residents with milder illness to overburdened hospitals.

“Calling emergency management made sense, because it was a disaster,” said Dr. Anna Hicks, a local geriatrician who helped coordinate the Cherry Springs strike team. “It felt like being in a natural disaster.”

Coronavirus outbreaks spread like wildfires in long-term care facilities, which house medically vulnerable residents and staff in relatively small spaces. So a growing number of states are treating them like one.

More than 40 percent of all coronavirus deaths in the United States have been tied to nursing homes, according to a New York Times analysis.

“Desperate times, like a pandemic, call for a different way of thinking,” said Dr. Timothy Chizmar, the emergency medical services director for Maryland. “The idea has roots in trauma settings, where it’s just not possible to take everybody off the scene — sometimes you need to take some medical care to them.”

Though initially coordinated at the top, with governors and state health departments sending the National Guard to the scene, strike teams are now being replicated on a much smaller scale in counties and local jurisdictions, including in states that were hot spots for the virus, like North Carolina.

It was one of the clearest signs of the consolidation in the retail industry triggered by the pandemic, as many other retailers have struggled or failed in recent months.

But a homebound nation continues to cause trouble for the commercial air industry. On Monday, Boeing’s chief executive said that the company would offer a second round of buyouts, adding to the 10 percent cut the company announced in April.

Mr. Calhoun did not specify how many jobs Boeing was hoping to cut. The new buyouts will help limit involuntary layoffs and will be offered to employees who work in parts of the company most affected by the pandemic, like Boeing’s commercial airplane and services businesses.

While recent federal data shows air travel is recovering again after stalling in July, the number of people flying each day is still less than a third of what it was a year ago. Industry executives expect that figure to remain depressed until a coronavirus vaccine is widely available.

Remdesivir, already in use to treat Covid-19 patients, enters a new phase of research.

Now researchers will examine whether adding another drug, beta interferon — which mainly kills viruses but can also tame inflammation — would improve remdesivir’s effects and speed recovery even more.

The additional drug, beta interferon, has already been approved for treatment of multiple sclerosis, which takes advantage of its anti-inflammatory effect.

The U.S. trial, called ACCT, is designed to move quickly. Known as an adaptive trial, it is a race between treatments. It tests one treatment against another, and, when results are in, the drug that won becomes the control drug for the next phase, in which it is tested against a different drug.

The new phase is the study’s third. A total of 1,000 patients will receive either remdesivir and a placebo or remdesivir and beta interferon.

Interferon is given as an injection. Remdesivir, made by Gilead Sciences, is given as an intravenous infusion.

The signs of a new wave of infection emerged over the summer as people began resuming much of their pre-coronavirus lives, traveling across France and socializing in cafes, restaurants and parks. Many, especially the young, have visibly relaxed their vigilance.

In recent days, France has recorded about 3,000 new infections every day, roughly double the figure at the beginning of the month, and the authorities are investigating an increasing number of clusters.

Thirty percent of the new infections are in young adults, ages 15 to 44, according to a recent report. Since they are less likely to develop serious forms of the illness, deaths and the number of patients in intensive care remain at a fraction of what they were at the height of the pandemic. Still, officials are not taking any chances.

“The indicators are bad, the signals are worrying, and the situation is deteriorating,” Jérôme Salomon, the French health ministry director, told the radio station France Inter last week. “The fate of the epidemic is in our hands.”

The course of the pandemic in Europe has followed a somewhat similar trend, with Spain also reporting new local clusters. But important disparities exist among countries. In the past week, as France reported more than 16,000 new cases, Britain reported 7,000, and Italy 3,000, according to data collected by The New York Times.

New research emerges on a rare immune syndrome that strikes some children with the virus.

Multisystem inflammatory syndrome, the severe illness that strikes some children with the coronavirus, is distinct from both Kawasaki disease and from Covid-19 in adults, according to a new study.

Most children infected with the coronavirus have mild symptoms, if any at all. But on very rare occasions, some develop so-called MIS-C, characterized by widespread inflammation in the heart, lungs, brain, skin and other organs. In the United States, there were 570 confirmed cases of the syndrome and 10 deaths as of Aug. 6.

When the children were acutely ill with MIS-C, these immune cells behaved much like those in adults with Covid-19. They produced vast amounts of certain disease-fighting molecules, as the adults did, and researchers saw declines in the B and T immune cells that are important for fighting the coronavirus.

As Hong Kong deals with a third wave of infections, it is ramping up testing of workers whose jobs place them at heightened risk of infection. As of Monday, 57 dockside laborers were among 65 cases linked to the city’s Kwai Tsing Container Terminals.

Some workers fear that cramped conditions in the dorms, some of which hold up to 20 people, could accelerate the spread of the virus.

Two of the Hong Kong dock workers who tested positive this week had been living temporarily in cramped port dormitories fashioned from shipping containers. They were trying to avoid traveling to their homes in Shenzhen, a city in the Chinese mainland — a trip that would have required them to quarantine upon their return.

On Monday, the Union of Hong Kong Dockers called on container companies to expand their accommodation for employees and to hire workers directly instead of outsourcing recruitment to smaller firms.

After battling back two waves of coronavirus infections, Hong Kong kept its new cases in the single digits for months. But cases began to spike again last month, to more than 100 per day, in part because officials had exempted seafarers, airline crews and others from mandatory quarantine.

The city has since reimposed strict social-distancing measures, and health officials have reported fewer than 100 infections a day for more than two weeks.

In other developments around the world:

• Sweden has temporarily recalled its diplomats from North Korea, citing increasing difficulties with travel and diplomatic postings, in part because of the pandemic. The Swedish embassy remains open with local staff, and “Sweden is engaged in dialogue with North Korea on these subjects,” a spokesman for the Swedish Ministry for Foreign Affairs said.

• Officials in New Zealand on Tuesday pushed back against President Trump’s assertion that the remote Pacific country was “having a big surge.” New Zealand, where the national election has been delayed from September to October because of a growing cluster in Auckland, has reported 22 deaths and fewer than 1,700 cases during the entire pandemic. “I’m not concerned about people misinterpreting our status,” Prime Minister Jacinda Ardern said.

• After a surge in infections in the past week, South Korea tightened social-distancing rules in the Seoul metropolitan area, banning all gatherings of more than 50 people indoors and more than 100 outdoors and shutting down high-risk facilities such as nightclubs, karaoke rooms and buffet restaurants. Prime Minister Chung Sye-kyun also said that churches must switch to online prayer services.

• Greece has locked down two facilities for migrants where new infections have been traced, after another overcrowded reception center was put under lockdown last week, the government said. The infections are part of a recent spike in the number of cases in Greece, which has weathered the pandemic relatively well so far, with just over 7,200 confirmed cases and 230 deaths. But the authorities this week introduced new restrictions to address local outbreaks and have warned of more measures if the upward trend continues.

• Countries putting their own interests ahead of others in trying to ensure supplies of a possible coronavirus vaccine are making the pandemic worse, the director general of the World Health Organization said on Tuesday, Reuters reported. “No one is safe until everyone is safe,” the agency’s leader, Dr. Tedros Adhanom Ghebreyesus, said during a briefing in Geneva. The organization also said the pandemic was now being driven by young people, many of whom were unaware they were infected, posing a danger to vulnerable groups.

N.Y.C. hotels and short-term rentals must make travelers from restricted states fill out health forms, the mayor says.

People who had recently traveled to areas outside the city accounted for 15 to 20 percent of cases in the city over the past month, according Dr. Jay Varma, one of the mayor’s health advisers. Mr. de Blasio urged New Yorkers to avoid traveling to places restricted by New York State unless it was absolutely necessary.

Gov. Andrew M. Cuomo said Tuesday that travelers from Alaska and Delaware will now also be required to quarantine for 14 days, joining a list of 31 other states as well as Puerto Rico and the U.S. Virgin Islands.

“If you have a choice in travel, don’t go where the problem is,” Mr. de Blasio said. He added, “Because, of course, if you go there there’s a chance you bring that disease back.”

Sororities and fraternities pose a virus-fighting challenge for colleges.

The New York Times has identified at least 251 cases of the virus tied to fraternities and sororities at colleges and universities across the United States.

At the University of California, Berkeley, 47 cases were identified in a single week in early July, most of which were connected to the Greek system. In Mississippi, a significant outbreak in Oxford, home to the state’s flagship university, was partially blamed on fraternity parties. At the University of Washington’s Seattle campus, at least 165 of the 290 cases identified by the school have been associated with its Greek Row.

As students return to campus, there have been virus outbreaks at residence halls and other university housing as well. More than 13,000 students, faculty and staff members at colleges have been infected with the coronavirus, according to a Times database of cases confirmed by schools and government agencies.

But fraternities and sororities have been especially challenging for universities to regulate. Though they dominate social life on many campuses, their houses are often not owned or governed by the universities, and have frequently been the site of excessive drinking, sexual assault and hazing. That same lack of oversight, some experts say, extends to controlling the virus. Even on campuses that are offering online instruction only, people are still living in some sorority and fraternity houses.

“Fraternity and sorority homes have long functioned as a kind of ‘no-fly zone’ for university administrations,” said Matthew W. Hughey, a professor of sociology at the University of Connecticut who has studied Greek life and social inequality on campuses. “The structure that’s already been set up makes them harder to control when it comes to the transmission of disease.”

The images seemed to touch a nerve in a world where lockdowns remain in place, where fear of public spaces and entertainment venues remains high, and where the idea of wading into a public pool is tantalizingly off limits to millions of people.

It was also another example of how life is slowly returning to normal in China, even in its hardest-hit city, as other countries — even those that coped well with the first wave, like South Korea and New Zealand — struggle with new outbreaks.

Shanghai Disneyland reopened in May, while movie theaters reopened across China last month. The step-by-step return of the country’s cultural life has not ignited any significant new outbreaks, though the government remains extraordinarily vigilant.

China on Tuesday reported no new locally transmitted cases of the virus on the mainland for the second consecutive day.

The pool party in Wuhan took place at Maya Beach Water Park in conjunction with a musical festival at an adjacent amusement park called Wuhan Happy Valley. They reopened in June, two months after the city’s 76-day lockdown was lifted, although in a nod to coronavirus precautions, the parks have limited capacity by 50 percent.

The parks have been holding Saturday night concerts since July 11, featuring some of the country’s biggest performers, including Panta.Q, who performed in Happy Valley last Saturday. Up next Saturday: The singer Big Year.
