While many in the United States celebrated a muted Thanksgiving over Zoom, millions of people traveled instead, rejecting the advice of public officials.
According to Transportation Safety Administration data, about 800,000 to one million people passed through T.S.A. checkpoints each day in the days before and after the holiday — far lower than the same period last year, but likely far higher than epidemiologists had hoped to see.
A United Airlines spokeswoman, Annabelle Cottee, said the week of Thanksgiving was “the busiest since March” for the carrier.
Americans also took to the roads. AAA predicted significant declines in bus, train and cruise travel, but predicted only a modest drop in car travel.
For several days leading up to Thanksgiving, as case numbers and hospitalizations across the country grew exponentially, political leaders and medical experts warned of the dangers of compounding the virus spread by being with others. In November alone, there have been more than 4.1 million cases and more than 25,500 deaths.
There were 91,635 current hospitalizations as of Nov. 28, according to the Covid Tracking Project, almost twice as many as there were on Nov. 1, and triple the number on Oct. 1.
Aware of the emotional resonance of the holiday, experts tried to thread a narrative from these numbers that would convince people of the danger. Their warnings were direct — sometimes stern, sometimes impassioned pleas.
“Keep the gatherings, the indoor gatherings as small as you possibly can,” Dr. Anthony S. Fauci, the nation’s top infectious disease expert, said on “Good Morning America” last week. By making that sacrifice, he said, “you’re going to prevent people from getting infected.”
The Centers for Disease Control and Prevention was also urging people not to travel. “All Americans want to do what they can to protect their loved ones,” Dr. Henry Walke, a Covid-19 incident manager at the C.D.C., said at a news briefing.
And though it would have been unrealistic to expect a public that is restive from months of restrictions to universally abide by such recommendations, the aftermath of those decisions will begin to unfold in the weeks ahead.
Dr. Fauci, during an appearance on the Sunday news program “This Week,” said the best course for Thanksgiving travelers might be “to quarantine yourself for a period of time.”
Dr. Deborah L. Birx, the White House coronavirus response coordinator, said that travelers “have to assume that you were exposed and you became infected and you really need to get tested in the next week.” She urged that travelers avoid anyone in their family over 65 or with underlying illnesses.
That guidance comes as the C.D.C. is considering shortening the recommended isolation period for infected people. And while it is too early to know if holiday travel will affect the virus’s spread, new research suggests that people are most infectious about two days before symptoms begin and for five days afterward, meaning this week will likely be crucial in containment.
The U.S. map shows a country where almost every region is a hot spot. States that were once spared, like Montana and Wyoming, have reported record deaths and infections, while states that were pummeled in the first wave are straining anew.
California on Sunday became the first state to report over 100,000 cases in a week, according to a New York Times database.
And in New Jersey, hospitalizations have increased 60 percent in the last two weeks and deaths have increased by 78 percent. Over three days in November, the positivity rate in Newark, the largest city in the state, was 19 percent.
“We begged people to have a somber, respectful, small Thanksgiving,” Gov. Philip D. Murphy said on Fox News Sunday. “And I want to give a shout out to New Jerseyans because I think overwhelmingly that’s what happened, but there’s a lot of fatigue out there.”
Mr. Murphy called the next few months “the fight of our lives,” while also citing the progress of vaccines and noting that there was “light at the end of the tunnel.”
And there was something to celebrate on Sunday in New York City, at least for some parents, when Mayor Bill de Blasio announced that he would reopen the city’s public elementary schools, abruptly shifting policy after an outcry from critics who questioned why gyms and bars remained open while schools were shut.
While some in the creative community on TikTok joke about the coronavirus vaccine or tease people who are part of the anti-vaccine movement, scientists and coronavirus vaccine participants are hoping to be a source to fight misinformation on the app.
In February, a scientist who goes by Dr. Noc on TikTok started noticing a need for science-based videos about the coronavirus that his expertise in working to develop an antibody treatment for Covid-19 could help provide.
He has since posted many videos addressing the coronavirus, including updates on vaccines, mink infected with the coronavirus and how some people with the virus can lose their sense of taste and smell. The videos, he said, have left him vulnerable to harassment from people against vaccines and masks.
Lately, Dr. Noc has found himself answering questions reflecting the fears and misconceptions about coronavirus vaccines that are sometimes perpetuated on the platform by jokes about side effects or forays into fictional narrative, like a sci-fi scenario in which the government kills those who refuse a vaccine.
“While people may appreciate them, they’re not going to go viral,” he said about his videos. “It’s a game of catch-up.”
Vaccine trial participants have also been describing their experiences and answering questions about the process for viewers.
Ashley Locke, 29, from Nashville, said she posted about her experience as a participant in AstraZeneca’s trial to document a journey in her life, but didn’t expect the more than two million views it has gotten, or the thousands of questions and comments.
Since that post, she’s been creating videos and answering questions from her comment section about side effects and wearing masks after being a part of the trial. She even brought in a friend, also a part of a trial, to talk.
But with all that, she said, she isn’t always successful in demystifying the vaccine.
“There are some people that are really out there that are convinced that it’s a microchip,” she said. “They’re a little too far gone to convince.”
With New York City’s unemployment rate at 13.2 percent, many people have turned to working for food delivery apps like DoorDash, Uber Eats and Grubhub, which have seen huge demand from customers.
While delivery drivers have been essential to feeding New Yorkers and keeping them safe, their working conditions, already precarious before the pandemic, have gotten worse.
Even as the food delivery companies have seen sales surge, the workers’ pay has remained erratic. Because the drivers are independent workers, they are not entitled to a minimum wage, overtime or any other benefits, like health insurance. Undocumented immigrants, who are not eligible for unemployment or federal coronavirus assistance, make up the bulk of the work force in New York.
The added competition from the surge in new workers has compounded the financial challenges. Advocacy groups estimate that there were roughly 50,000 delivery workers before the pandemic — a number they say has grown exponentially. Uber alone said it had added 36,000 couriers in New York since March.
DoorDash and Uber said they had provided extra help to delivery drivers during the pandemic, including offering sick pay to those who were infected. DoorDash, the nation’s largest food delivery app, said it provided access to low-cost telemedicine appointments.
DoorDash also said it had changed its pay model, which came under fire last year after it was revealed that tips were being used to subsidize its payments to workers. The company recently reached a $2.5 million settlement with prosecutors in Washington, D.C., after being accused of misleading consumers over how it tipped its workers.
Drivers for food delivery apps are typically paid per delivery depending on the estimated duration and distance of a trip, plus tips. The work can be convenient for people supplementing a main source of income, but a struggle for those who depend on it as a primary job, advocates for the workers said.
A cohort of 63 international students on Monday arrived in Australia under a pilot program that allows them to resume their studies, even as the country’s borders remain closed because of the pandemic.
The students, the first group of international students allowed in since March, arrived at Darwin International Airport in the Northern Territory from Singapore. They are from mainland China, Hong Kong, Japan, Vietnam and Indonesia.
All of them tested negative for the coronavirus 72 hours before boarding the charter flight. They will be required to quarantine at a former workers’ camp outside the city of Darwin for 14 days before being allowed to re-enter the campus at Charles Darwin University.
The education sector, crucial to the Australian economy, is set to lose billions of dollars if the country’s borders do not reopen before the end of 2021. According to research from Victoria University, the loss of international students is also affecting the makeup of Australia’s cities.
In September, Charles Darwin University made a deal with the state and the federal government that would enable students to return from overseas to study. The success of the program could influence whether more international students can return to study in other states, including South Australia and the Australian Capital Territory.
Speaking to the local news media, the students — some of who had become stranded while visiting family overseas — said they felt lucky to return to Australia, which is beginning to reopen as states eliminate, or come close to eliminating, the spread of the coronavirus.
Xitao Jiang, a 23-year-old student from China returning to Australia, told the Australian Broadcasting Corporation on Sunday that was “very lucky” to have the opportunity to return to the country and study at the university in Darwin.
By the end of the third week of England’s second national lockdown, which began early this month in a bid to stem a second wave of coronavirus infections, the number of new cases has fallen 30 percent, according to new data.
Some parts of northern England, which had been hit particularly hard by the new outbreak, experienced an even greater drop, the latest interim findings from Imperial College London’s React study showed.
But Matt Hancock, the British health secretary, warned that the data, while promising, showed the country could not “take our foot off the pedal just yet,” according to the BBC. In a post on Twitter late Sunday, Mr. Hancock cautioned that “we mustn’t waste our progress now we can see light at the end of the tunnel” with mass testing and promising coronavirus vaccine candidates on the horizon.
England’s current lockdown is set to end just after midnight Wednesday. But the lifting of restrictions will be different across the country, as regions move into one of three tiers based on their current rate of infection. Britain is still grappling with the highest number of Covid-19 deaths in Europe and its deepest recession on record, with experts warning that the knock-on effects of the pandemic could last for years.
All through the fall, teachers have been at the center of vehement debates over whether to reopen schools for in-person instruction — often vilified for challenging it, sometimes praised for trying to make it work.
But these debates have often missed just how thoroughly the coronavirus has upended learning in the 130,000 schools in the United States, and glossed over how emotionally and physically draining pandemic teaching has become.
In more than a dozen interviews with The New York Times, educators described the immense challenges, and exhaustion, they have faced. Some recounted whiplash experiences of having their schools abruptly open and close, sometimes more than once.
Others described the stress of having to lead back-to-back group video lessons for remote learners, even as they continued to teach students in person in their classrooms. Some educators said their workloads had doubled.
Many teachers said they had also become impromptu social workers for their students, directing them to food banks, acting as grief counselors for those who had family members die of Covid-19 and helping pupils work through their anxiety, depression and isolation. Often, the teachers said, their concern for their students came at a cost to themselves.
“Teachers are not OK right now,” said Evin Shinn, a literacy coach at a public middle school in Seattle, noting that many teachers were putting students’ pandemic needs above their own well-being.
Experts and teachers’ unions are warning of a looming burnout crisis among educators that could lead to a wave of retirements, undermining the fitful effort to resume normal public schooling. In a recent survey by the National Education Association, the country’s largest teachers’ union, 28 percent of educators said the coronavirus had made them more likely to leave teaching or retire early.
