three movie theaters in the San Antonio area became some of the first in the country to reopen, a move that worried infectious disease experts but was applauded by those who went to the show.
Elsewhere, protesters pressing for the loosening restrictions gathered in the capitals of Kentucky, Oregon and Florida, where the governor has already announced a relaxing of restrictions. In Stillwater, Okla., officials abandoned a requirement that people wear masks in shops and restaurants after workers were faced with violent threats.
Former President George W. Bush is calling on Americans to put aside partisan differences, heed the guidance of medical professionals and show empathy for those stricken by the coronavirus and resulting economic impact.
In a three-minute video message, Mr. Bush, struck a tone of unity that seemed to contrast with the more combative approach taken at times by President Trump, as the former president evoked the sense of national solidarity in the wake of the Sept. 11, 2001 attacks.
“Let us remember how small our differences are in the face of this shared threat,” Mr. Bush said in the professionally produced video, part of a series of videos aired online called The Call to Unite that also featured Oprah Winfrey, Tim Shriver, Julia Roberts and others.
The lifting of stringent rules across the nation signaled a new phase in the country’s response to the virus and came even as confirmed cases nationally continue to grow.
“It’s clearly a life-or-death-sort-of-level decision,” said Dr. Larry Chang, an infectious diseases specialist at Johns Hopkins University. “If you get this wrong, many more people will die.”
The Philippines suspends commercial air travel into the country.
The Philippines will suspend all commercial flights into the country beginning Sunday, joining several countries that have suspended most air travel in response to the pandemic.
The Manila International Airport Authority announced the move on its Facebook page. It did not give an end date for the suspension of commercial passenger flights, which began at 8 a.m. Sunday. Other air traffic, including cargo flights and those transporting medical supplies, will be allowed to continue, it said.
A handful of countries have similarly blocked almost all air travel in an effort to control the spread of the coronavirus, moves that coincide with new restrictions on migration that have been imposed around the world.
India suspended international and domestic passenger flights in late March. On Saturday the country’s Directorate General of Civil Aviation said the restrictions will be extended until May 17. Thailand will continue to bar most flights to the country until May 31.
Last month, Myanmar extended its suspension of all flights to the country until May 15. And Nepal said it would extend a suspension of all domestic and international flights until May 15.
The United Arab Emirates has suspended flights until further notice, and Argentina has banned commercial flights until Sept. 1, one of the longest such restrictions.
The International Civil Aviation Organization says international air travel could drop between 44 percent and 80 percent over the course of 2020, compared with the previous year. The overall reduction in the number of passengers could reach 1.5 billion, it said.
The race for a vaccine is trying to speed up a process that normally takes years.
Four months after the coronavirus began its deadly march around the globe, the search for a vaccine has taken on an intensity never before seen in medical research, with huge implications for public health, the world economy and politics.
With political leaders — not least President Trump — increasingly pressing for progress, and with big potential profits at stake for the industry, drug makers and researchers have signaled that they are moving ahead at unheard-of speeds.
But the whole enterprise remains dogged by uncertainty about whether any coronavirus vaccine will prove effective, how fast it could be made available to millions or billions of people, and whether the rush — compressing a process that can take 10 years into 10 months — will sacrifice safety.
“We are going to start ramping up production with the companies involved,” Dr. Anthony S. Fauci, the director of the National Institute of Allergy and Infectious Diseases and the federal government’s top expert on infectious diseases, said on NBC this week. “You don’t wait until you get an answer before you start manufacturing.”
Two of the leading entrants in the United States, Johnson & Johnson and Moderna, have announced partnerships with manufacturing firms, with Johnson & Johnson promising a billion doses of an as-yet-undeveloped vaccine by the end of next year.
While scientists and doctors talk about finding a “global vaccine,” national leaders emphasize immunizing their own populations first. Mr. Trump said he was personally in charge of “Operation Warp Speed” to get 300 million doses into American arms by January. The most promising clinical trial in China is financed by the government. And in India, the chief executive of the Serum Institute of India — the world’s largest producer of vaccine doses — said that most of its vaccine “would have to go to our countrymen before it goes abroad.”
But George Q. Daley, the dean of Harvard Medical School, said thinking country by country rather than in global terms would be foolhardy since it “would involve squandering the early doses of vaccine on a large number of individuals at low risk, rather than covering as many high-risk individuals globally” — health care workers and older adults — “to stop the spread” around the world.
There’s a new reality for places where coronavirus is under control. Parts of the world already live in it.
Worshipers at one of Seoul’s largest Catholic churches must refrain from singing hymns or saying “amen” for fear of spreading saliva. Priests sanitize their hands during communion. Holy water has been removed from the chapel.
“This should become the new normal from now on,” said Gong Mi-young, 53, who owns a tutoring school and attended Mass one night this week at Myeongdong Church in the South Korean capital. “We have to be ready for war.”
South Korea even has a name for the new practices: “everyday life quarantine.” The authorities recently released a 68-page guide, offering advice on situations like going to the movies (“refrain from shouting”) and attending funerals (“bow your head instead of hugging”).
As cities in Asia, Australia and elsewhere get their coronavirus outbreaks under control, churches, schools, restaurants, movie theaters and even sporting venues are starting to open, creating a sense of normalcy for people who have spent weeks and even months in isolation.
But they are returning to a world reimagined for the age of coronavirus, where social distancing, hygiene standards and government-imposed restrictions are infused into nearly every activity — a way of life that is likely to persist until a vaccine or a treatment is found.
In Hong Kong, tables at restaurants must be spaced at least five feet apart and customers are given bags to store their face masks during dining.
In China, students face temperature checks before they can enter schools, while cafeteria tables are outfitted with plastic dividers.
In South Korea, baseball games are devoid of fans and players can’t spit on the field.
The new social customs and mandates in Beijing, Hong Kong and Seoul, as well as Sydney, Australia, and Taiwan’s capital, Taipei, offer a preview of what might soon be common globally.
Researchers in Norway have a suggestion for how U.S. schools might reopen.
All but a few U.S. states have suspended in-person classes for the rest of the academic year, and some are preparing for the possibility of shutdowns or part-time schedules in the fall.
Whenever students do come back, classes are unlikely to look the same. There may be staggered half-day classes or one-day-on, one-day-off schedules so desks can be spread out and buses can run at lowered capacities.
As different parts of the United States attempt to figure out what and when to reopen, and whether their lockdown measures are making a difference, two Norwegian medical researchers have suggested an approach to safely reopening schools.
The researchers, Dr. Mette Kalager and Dr. Michael Bretthauer, a husband-and-wife team at the University of Oslo, have proposed a test in which similar school districts in adjacent towns are compared when one stays shut and the other is carefully reopened, with students and teachers in both districts tested at the start and end of a 10- to 14-day cycle. If virus transmissions don’t increase in the reopened school, the restrictions would be scaled back further.
In the best-case scenario — no increased transmission — all schools could open after three to six weeks.
