Coronavirus Live Updates: World Approaches One Million Deaths

[ad_1]

A top Trump official dismisses a report that he pushed the F.D.A. to soften new vaccine guidelines.

The White House chief of staff, Mark Meadows, dismissed reports that he had pressured the Food and Drug Administration to soften new, stricter guidelines that the agency was preparing for the emergency authorization of coronavirus vaccines.

“Why would we do that?” he asked Margaret Brennan on the CBS program “Face the Nation”on Sunday.

Mr. Meadows said he was interested in the guidelines purely as a matter of quality control: “My challenge to the F.D.A. is just make sure it’s based on science and real numbers.”

The new guidelines under development would lay out more specific criteria for clinical trial data than the current guidelines, and would recommend that the data be vetted by a committee of independent experts before the F.D.A. authorizes any vaccine, according to several people familiar with a draft.

President Trump suggested on Wednesday that the new guidelines were a “political move,” and that the White House might not approve them.

Also on “Face the Nation,” Scott Gottlieb, who was commissioner of the F.D.A. from May 2017 to April 2019, said that the expected guidelines did not represent “a revision in the agency standards or any kind of higher bar” but rather “an articulation of the principles and standards that the F.D.A. has been using for a long time and frankly been communicating to the companies that are developing vaccines.”

Dr. Gottlieb, a physician now on the board of Pfizer, one of the companies racing to develop a coronavirus vaccine, said he believed that there was wide agreement that the guidelines, as discussed publicly, “were mostly in line with everyone’s expectations.”

He said he preferred to have the F.D.A. issue the guidance “because it would provide more transparency,” but regardless, “I think these are going to be the principles that govern that process.”

As global deaths approach one million, new hot spots continue to emerge.

In places where the autumn chill is ushering people back into homes, classrooms and offices, health experts warn that the virus may resurge even in areas that so far have restrained its spread.

The virus poses a greater threat in crowded indoor spaces than it does outdoors. Southern U.S. states, for example, saw a spike in infections when the temperatures soared this summer, prompting people to remain inside with the air-conditioners humming.

“I’m a little concerned we’re going to see that shift to the northern latitudes as the weather gets cold,” said Linsey Marr of Virginia Tech in Blacksburg, who studies how viruses move through the air.

Unless you are living with an infected person — in which case the Centers for Disease Control and Prevention offers specific guidelines to follow — protecting yourself at home does not require extraordinary measures, Dr. Marr said. And when you venture elsewhere, wearing a face covering and washing your hands are still the best ways to protect yourself indoors.

Health experts offered several tips for dodging the virus indoors: Open the windows, buy an air filter — and forget the ultraviolet lights. Fear of the risk of transmission indoors has fueled a market for expensive devices that promise to scrub surfaces — and even the air — but most of those products are overkill and may even have unintended harmful consequences.

“Anything that sounds fancy and isn’t tried-and-true — those are all things to avoid,” said Delphine Farmer, an atmospheric chemist at Colorado State University in Fort Collins. “Soap and water work beautifully.”

Managers of larger buildings should encourage those who can to work from home and adopt strategies like adding air filters and disinfecting surfaces. Researchers at the Massachusetts Institute of Technology have created an app to determine how many people can safely congregate in a given space and for how long.

But regardless of these precautions, the optimal strategy is simply to wear a mask indoors, said Martin Bazant, a chemical engineer at M.I.T., adding, “That’s a much bigger effect than any of those strategies would provide.”

Infections are skyrocketing in France, with a daily average of more than 10,000 new cases over the past seven days, more than double the number at the height of the country’s first wave in the spring.

“We have been warning for several weeks now that we have not defeated the epidemic,” France’s health minister, Olivier Véran, told French media on Sunday. “The virus has not disappeared. The epidemic has picked up again.”

The number of Covid-19 deaths has risen by 83 percent over the last 14 days, according to a New York Times database. Still, the death rate — averaging about 50 deaths per day in the last week — is far lower than it was in the spring, when the figure averaged more than 1,000 per day. Nonetheless, dozens of cities and regions across the country are preparing to enforce new restrictions on Monday, in an attempt to stem the rising tide of infections.

French authorities have placed a number of French cities, including Paris, Lyon and Bordeaux, on a “reinforced alert” level, which, starting on Monday, will restrict public gatherings to no more than 10 people. Bars will have to close early and enclosed sport establishments must shut down completely.

Meanwhile, hospitals are again under strain, with some 600 new Covid-19 hospitalizations each day since mid-September. Covid-19 patients now represent at least 10 percent of patients in intensive care across the country.

In recent months, France has ramped up its testing policy, with more than one million tests conducted per week, or about five times more than in April. But French laboratories lack the capacity to keep up with the number of tests carried out, resulting in a backlog of tests that have hampered France’s strategy for preventing a second outbreak.

“It’s a remarkable thing — and an achievement that belongs to every single Victorian,” he said. “Because with grit and with guts and with heart, we are beating this thing. We are driving it down. We are winning.”

In other global developments:

  • With positive coronavirus tests reaching new highs, the number of critically ill threatening to overload intensive care wards and hospitals reporting alarming numbers of younger patients, Israeli officials pleaded with the public on Sunday to heed lockdown measures heading into Yom Kippur, the holiest day on the Jewish calendar.

  • In Madrid, about 1,000 protesters took to the streets on Sunday to demand an end to a partial lockdown imposed by the regional government last Monday on about a million residents of specific neighborhoods, most of them in working-class suburbs. While the Madrid authorities have argued that the lockdown was needed to contain a second wave of infections, the decision has sparked protests and outrage among residents who consider it discriminatory. That viewpoint was bolstered on Friday when Spain’s health minister, Salvador Ila, said that Madrid should instead have introduced stricter restrictions across the whole capital region.

  • Britain could end up “caught in a cycle of epidemic waves” without further restrictions, a member of the government’s scientific advisory board has warned. The adviser, Jeremy Farrar, wrote in the Times of London that tightened measures announced by Prime Minister Boris Johnson this past week were a “fudge” and would “neither deliver an open economy nor save lives.” Mr. Farrar called for a ban on people from different households meeting indoors, and said another closure of restaurants, pubs, gyms, places of worship and nonessential shops should also be considered as the country tries to arrest a steep climb in infections.

  • South Korea on Sunday called for a joint investigation into the death of a South Korean official who was killed by North Korean troops who discovered him floating in North Korean waters. South Korea said that the official was trying to defect and that the troops shot him and set his body on fire on the unsubstantiated fear that he might be infected with the virus. The North disputes key parts of that account. “Since there are gaps in the findings by South and North Korea, we request a joint investigation so we can establish the truth as soon as possible,” said Suh Choo-suk, a deputy director of national security in South Korea​.

New York’s decision followed moves that other administrators have been making since last March, when schools were forced to transition to online learning and officials realized they could do the same during hazardous weather.

“We said, ‘Wow, this could really be a solution for us for snow days in the future,” said Robb Malay, a school superintendent who oversees seven districts in southern New Hampshire.

For many teachers, the end of the snow day looks inevitable, said Denis Anglim, 31, who teaches high school English and history in Philadelphia.

“For the sake of continuity of the curriculum, it’s a good thing,” he said. “But not in terms of hanging on to the nostalgia of waking up at 5 a.m. and looking at the ticker at the bottom of the television to see if your school will be closed.”

The official poster for the 2020 French Open, which began Sunday and runs through Oct. 11, shows a view of a sunlit clay court through a dense ring of green leaves.
