Coronavirus Live News and Updates

‘We have to try something different’: Experts call for a large-scale rethinking of the U.S. testing strategy.

While most coronavirus tests to date have relied on an ultra-accurate procedure called PCR, severe supply shortages have slowed the turnaround of results, stretching to more than a week — or three — in some parts of the United States. That has complicated, if not crippled, efforts to detect and track the spread of the virus.

The best chance to rein in the sprawling outbreaks, experts said, requires widespread adoption of less accurate tests, as long as they are administered quickly and often enough.

“Even if you miss somebody on Day 1,” said Omai Garner, director of clinical microbiology in the U.C.L.A. Health System. “If you test them repeatedly, the argument is, you’ll catch them the next time around.”

This quantity-over-quality strategy has its downsides, and is contingent on an enormous supply of testing kits. Currently, only a handful of speedy tests have been cleared by the Food and Drug Administration for emergency use. But many experts now believe more rapid, frequent testing would be enough to identify those who need immediate medical care — and perhaps even pinpoint those at greatest risk of spreading the disease.

One such option includes antigen testing, which, at its simplest, could provide a fast answer in the same way as pregnancy tests. Users could swab their mouths or noses or spit into a tube, then read the results as colored bars on a strip of paper within minutes. These tests could be done at a doctor’s office, or even at home — no fancy machines or specially trained personnel required — and cost just a few dollars each, perhaps even less. And there would be no delays of a week or longer.

The approach is unconventional for lab researchers, who have traditionally valued accuracy above all else. But given the status quo, “Our backs are against the wall, and it’s Hail Mary time,” said Susan Butler-Wu, a clinical microbiologist at the University of Southern California. “We have to try something different.”

France and Germany have each recorded a higher number of daily new coronavirus cases this week than either country has seen in months. France reported 1,695 new cases on Wednesday, and Germany on Thursday reported more than 1,000.

The rise in cases for both countries come as other Western European countries, like Spain and Belgium, are also facing surges. And though the numbers are high, they are not on the level of the spikes being seen in the United States.

Germany’s public health authority, the Robert Koch Institute, said new cases were spread across the country, and were not concentrated in one region as more recent spikes have been.

In France, which had been seeing a slow resurgence of the pandemic, the 1,242 daily average of cases since the beginning of August has almost reached the level of infections in the first week of May, when the country was still under lockdown. And the number of Covid-19 patients in intensive care units, which had been steadily falling since early April, has risen very slightly in recent days.

As numbers began rising last week in Germany, Lothar Wieler, the president of the Robert Koch Institute, had warned that Germans were becoming too lax and failing to uphold the social-distancing and mask-wearing requirements that remain in place.

In France, the scientific council that advises President Emmanuel Macron warned that a second wave of infections by the fall was “highly possible” given current trends. The council called on large cities to prepare home-confinement strategies that could be tightened or loosened in step with the evolution of the pandemic.

France has had a total of at least 194,000 coronavirus cases and at least 30,000 deaths, according to a New York Times database. Germany has had at least 213,000 cases and at least 9,100 deaths.

Nearly 1.2 million workers in the United States filed new claims for state unemployment benefits last week, the government reported on Thursday. It was the lowest weekly total since March but still topped the extraordinarily high number of one million for 20 straight weeks.

An additional 656,000 claims were filed by freelancers, part-time workers and others who do not qualify for regular state jobless aid but are eligible for benefits under a separate federal program, the Labor Department said. Unlike the state figures, that number is not seasonally adjusted.

The number of new claims is down from the stratospheric levels of the pandemic’s early days, but signals the continued damage that the pandemic has inflicted on the American economy.

“There is a resurgence of Covid cases around the country that is tempering economic activity and employment gains,” said Kathy Bostjancic, chief U.S. financial economist at Oxford Economics.

And now that emergency federal benefits have expired, the unemployed will not be receiving the $600-a-week supplement that helped them pay bills through the spring and early summer.

Nearly every country has struggled to contain the coronavirus and made mistakes along the way, yet only one affluent nation has suffered a severe, sustained outbreak for more than four months: the United States.

Led by David Leonhardt, a team of New York Times journalists set out to reconstruct the unique failure of the United States, through interviews with scientists and public health experts around the world. The reporting points to two central themes. David writes:

First, the United States faced longstanding challenges in confronting a major pandemic. It is a large country at the nexus of the global economy, with a tradition of prioritizing individualism over government restrictions. That tradition is one reason the United States suffers from an unequal health care system that has long produced worse medical outcomes — including higher infant mortality and diabetes rates and lower life expectancy — than in most other rich countries.

“As an American, I think there is a lot of good to be said about our libertarian tradition,” Dr. Jared Baeten, an epidemiologist and vice dean at the University of Washington School of Public Health, said. “But this is the consequence — we don’t succeed as well as a collective.”

The second major theme is one that public health experts often find uncomfortable to discuss because many try to steer clear of partisan politics. But many agree that the poor results in the United States stem in substantial measure from the performance of the Trump administration.

In no other high-income country — and in only a few countries, period — have political leaders departed from expert advice as frequently and significantly as the Trump administration. President Trump has said the virus was not serious; predicted it would disappear; spent weeks questioning the need for masks; encouraged states to reopen even with large and growing caseloads; and promoted medical disinformation.

“These large parties are unsafe and can cost Angelenos their lives,” Mr. Garcetti said at a news conference on Wednesday. “That is why, tonight, I am authorizing the city to shut off Los Angeles Department of Water and Power service in the egregious cases in which houses, businesses and other venues are hosting unpermitted large gatherings.”

He said that beginning on Friday night, “if the L.A.P.D. responds and verifies that a large gathering is occurring at a property, and we see these properties reoffending time and time again, they will provide notice and initiate the process to request that D.W.P. shut off service within the next 48 hours.”

He added that this would not apply to small home gatherings, though he urged residents to avoid those, too.

“Some research has shown that 10 percent of people cause 80 percent of the spread,” Mr. Garcetti said. “These super-spreader events and super-spreader people have a disproportionate impact on the lives that we are losing, and we cannot let that happen like we saw on Mullholland Drive on Monday night.”

A surge in coronavirus cases since mid-June in California has prompted officials to reconsider their moves to loosen some restrictions. California surpassed New York last month as the state with the highest number of coronavirus cases.

For some Britons, a return to a disrupted career may not be possible.

As a national lockdown was imposed in England in March, a food deliverer, Hanna Scaife, watched her weekly hours dwindle to nothing as restaurants across Teesside, in the northeastern part of the country, shut their doors. Business has not gotten much better since then.

More than half of Americans who flew in the past year are not ready to do so again, according to a new survey, underscoring the difficulty airlines face in convincing people it is safe for them to get back on planes.

Test results for North Korea’s first suspected coronavirus case were “inconclusive,” a World Health Organization official has said, after the case triggered quarantine orders for more than 3,600 people.

North Korea’s state-run news media has said the patient is a man who defected to South Korea three years ago but secretly crossed back to the border city of Kaesong last month. North Korea later declared a “maximum” national emergency and put Kaesong on lockdown.

North Korea, one of the world’s most isolated countries, has repeatedly said that it has no cases of the virus, but outside experts are skeptical. The local news media said last week that the national caseload was still zero, without providing further details on what happened to the man.

Dr. Edwin Salvador, a W.H.O. representative to North Korea, said in a statement on Thursday that the test results for the man remained “inconclusive.” Extensive contact tracing is underway, he added, with 64 of the man’s first contacts and 3,571 secondary ones under quarantine in government facilities for 40 days.

Dr. Salvador said in a separate statement that hundreds of workers at a North Korean seaport and at the border with the Chinese city of Dandong who came into contact with imported goods have also been quarantined.

North Korea’s authoritarian government has adopted drastic measures against the virus, including sealing its borders in January and closing off business with China, which accounts for 90 percent of its external trade.

A coronavirus outbreak could further damage the North’s economy, which is already hobbled by international sanctions, and strain its woefully underequipped public health system. Dr. Salvador said the government had designated 15 laboratories for Covid-19 testing, and that all schools were on an extended summer break.

Fifty million face masks bought by the British government for the National Health Service in April will not be used because of safety concerns, the BBC reported on Thursday.

The masks, which were bought as part of a 252 million-pound contract, ($332 million), use ear loop fastenings instead of head loop fastenings. The government found that they did not fit tightly enough, according to legal documents seen by the BBC.

The Department of Health and Social Care said it was unable to comment on the specifics of the case because of continuing legal proceedings but said there was a “robust” process in place to ensure that all orders of personal protective equipment are of high quality and meet strict safety standards.

Ayanda Capital, the supplier of the masks, was not immediately available for comment but told the BBC that the equipment met all the specifications that the government had set out.

In the early stages of the pandemic, the government came under fierce criticism over shortages of personal protective equipment, particularly respirator masks that protect health workers from inhaling harmful materials.

“Throughout this global pandemic, we have been working tirelessly to deliver PPE to protect people on the front line,” a government spokesman said, adding, “Over 2.4 billion items have been delivered, and more than 30 billion have been ordered from U.K.-based manufacturers and international partners to provide a continuous supply, which meets the needs of health and social care staff both now and in the future.”

Myanmar jails a Canadian pastor for attending a large gathering.

A pastor from Canada, who contracted the virus in Myanmar after preaching that Christians were immune to it, was sentenced to three months in prison on Thursday for violating the country’s strict rule against large gatherings.

The Myanmar-born preacher, David Lah, was found guilty of attending a 27-day Christian gathering in Yangon, the country’s largest city, that began in March and is blamed for spreading the virus to at least 72 people.

At the time, the government had prohibited gatherings of five or more people in an effort to contain the virus. The limit on gatherings was raised last week to 15.

The spring gathering, where Mr. Lah was a featured speaker, is Myanmar’s biggest known coronavirus cluster so far. Mr. Lah was diagnosed with Covid-19 days after it ended.

In one of his sermons at the gathering, he claimed that the coronavirus had leaked from a “nuclear biological weapon” but that those who believed in God would be spared.

“For anyone who hears the word of God,” he said, “that disease will never come and infect you.”

One of Myanmar’s two vice presidents, U Henry Van Thio, was tested for the disease after meeting separately with Mr. Lah, the authorities said. His test result was negative.

Mr. Lah, who has been imprisoned since May 20 awaiting trial, will be released in two weeks. U Wai Tun, who organized the event and played drums there, was also convicted and sentenced to three months.

Christians, who make up 6 percent of Myanmar’s population, are the largest religious minority in the predominantly Buddhist nation.

As of Thursday, Myanmar had reported 357 coronavirus cases and 6 deaths. Its testing rate — 2,219 per million people — is among the lowest in the world.

Mass infection at a retirement home came through the ventilation system, a Dutch report finds.

A leaked report by the Dutch National Institute for Public Health and the Environment seems to support the theory that the coronavirus can be transmitted through the air.

The case, in Maassluis, in the western Netherlands, is one the clearest examples of a warning by 239 experts that the virus is airborne.

The report, published on Wednesday by the Dutch newspaper De Volkskrant and 1Vandaag, a current-affairs show, focused on a retirement home where in June almost an entire ward of patients was infected.

Despite wearing face masks continuously except for lunch breaks, 18 staff members were also infected. When a newly installed air-ventilation system was inspected, the health authorities found large quantities of the virus on the mesh covering air intake and extraction units and in its filters.

“There is simply no other explanation possible, this is how everybody there got infected, all at the same time, through aerosols,” said Maurice de Hond, a data specialist who has long criticized the Dutch health authorities for ignoring spread through aerosols. “We need to realize this before autumn comes and more people will gather indoors.”
