Officials in eight states — Alaska, Arizona, California, Georgia, Idaho, Oklahoma, South Carolina and Texas — also announced single-day highs.The record comes as Dr. Anthony S. Fauci, the nation’s top infectious disease expert, testified before Congress on Tuesday that the rate of new coronavirus infections could more than double to 100,000 a day if current outbreaks were not contained. He warned that the virus’s march across the South and the West “puts the entire country at risk.”Tuesday was the fourth time in a week that the United States posted a new single-day case record.The number of new cases in the United States has shot up by 80 percent in the past two weeks, according to a New York Times database.More than 4,600 new cases of the virus were announced in Arizona, by far its most in a single day, as Vice President Mike Pence planned to travel there on Wednesday. More than 7,800 new cases were announced across California and more than 6,800 in Texas.The increase in infections came as the leaders of the most populous counties in Texas pleaded with Gov. Greg Abbott to allow them to issue stay-at-home orders. “We are having an experiment, a gamble, in the hopes that we can be the first community that suddenly flattens the curve without a stay-at-home order,” said Lina Hidalgo, the executive in Harris County, which includes Houston, the hardest-hit area of the state.Videotranscripttranscript‘I Am Very Concerned,’ Fauci Tells Senators About Coronavirus SpreadDr. Anthony S. Fauci and Dr. Robert R. Redfield testified before the Senate as more states struggle to contain the coronavirus.“It is going to be very disturbing, I will guarantee you that, because when you have an outbreak in one part of the country, even though in other parts of the country they’re doing well, they are vulnerable. I made that point very clearly last week at a press conference. We can’t just focus on those areas that are having this surge, it puts the entire country at risk. We are now having 40-plus thousand new cases a day. I would not be surprised if we go up to 100,000 a day if this does not turn around. And so I am very concerned.” “The Covid-19 pandemic is the most significant global public health challenge that we have faced as a nation in more than a century. In the United States, daily cases are increasing after an extended decline. We’re seeing significant increases in the Southeast and Southwest regions of this nation. The number of jurisdictions in upward trajectory has continued to increase. Now 29 of 55 jurisdictions fall into this category. The evidence tells us that these cases are driven by many factors to include: increased testing, community transmission and outbreaks in the settings such as nursing homes and occupational settings. Hospitalizations now are going up in 12 states. While data is the backbone of this response, containing the outbreak depends on four core interventions: readily available testing, comprehensive contact tracing, timely isolation of known cases and quarantine to break the transmission. We are not defenseless against this disease. We have powerful tools at our disposal.”Dr. Anthony S. Fauci and Dr. Robert R. Redfield testified before the Senate as more states struggle to contain the coronavirus.CreditCredit…Pool photo by Kevin DietschCalifornia’s case count has exploded in recent days — leading the governors of New York, New Jersey and Connecticut to tell travelers from California to quarantine for 14 days, joining the ranks of travelers from other hard-hit states.And even states that had reported improvements are starting to see the number of new cases rise, causing governors to rethink their plans to get residents back to work.Dr. Fauci offered his grim prediction while testifying on Capitol Hill, telling senators that no region of the country is safe from the virus’s resurgence.“I can’t make an accurate prediction, but it is going to be very disturbing, I will guarantee you that,” Dr. Fauci said, “because when you have an outbreak in one part of the country, even though in other parts of the country they are doing well, they are vulnerable.”In parts of the Midwest, the numbers are rising again.ImageWorkers at a mobile coronavirus testing site distributed self-tests in Chicago last week.Credit…Scott Olson/Getty ImagesWhen June began, new case reports were dropping in Kansas. Detroit, hit hard early on, was continuing to show improvement. Wisconsin was finally looking better.What a difference a month can make.The Midwest, which had been a national bright spot, is now seeing the beginnings of a surge in coronavirus cases. Several in the region had increasing case numbers. And even in places where case numbers have remained mostly flat, like Illinois and Minnesota, new hot spots have emerged.In Kansas, the governor on Monday ordered residents to wear masks as case numbers lurched back toward their peak levels. In Wisconsin, new cases in the Madison area have reached a new high. And in Ohio, the cases in counties that include Cincinnati and Cleveland have been doubling in the past two weeks. Gov. Mike DeWine, a Republican, said the Ohio increases were not the result of more testing, contradicting the messaging from the White House and some other Republican governors.“If the spread of this virus remained at a low level, more testing should show a lower positivity — there simply wouldn’t be as many cases to pick up with testing,” said Mr. DeWine, who asked for federal help responding to upticks in the Cincinnati and Dayton areas. “Instead, the creeping up of our positivity rate even as we are doing more testing means that we are likely picking up signs of broader community spread.”The Republican Senate health committee chairman urges Trump to set a better example on masks.ImagePresident Trump at the White House in June.Credit…Pete Marovich for The New York TimesMasks — and President Trump’s refusal to wear one — were a central topic of the Senate health committee hearing on Tuesday, as Senator Lamar Alexander of Tennessee, the committee chairman, called on the president to set a better example by occasionally covering his face.At the outset of the hearing, Mr. Alexander, a Republican, lamented that wearing a mask had “become part of the political debate,” and said he had “suggested that the president occasionally wear a mask, even though in most cases” Mr. Trump does not need to do so.“The president has plenty of admirers,” Mr. Alexander said. “They would follow his lead, it would help end this political debate. The stakes are too high for this political debate about pro-Trump, anti-Trump to continue.”The senator’s remarks, an echo of comments he made over the weekend, were a striking example of a Republican criticizing the president by name. As they have in the past, health experts emphasized that masks were essential to containing the virus, though they avoided direct mention of Mr. Trump.Europe opens its doors — just not to Americans. What we know about the ban.ImageOrly Airport near Paris last week. The move by the European Union aims to balance health concerns with the need to bolster trade, not least the tourism industry.Credit…Christophe Petit Tesson/EPA, via ShutterstockAfter months of lockdown, European nations are about to open their borders to nonessential travelers from a list of countries in which the pandemic has been deemed sufficiently under control. The United States is not on that list.The State Department is still advising Americans to avoid all international travel, but many may be wondering what a newly reopening Europe might mean for them.Here is what we know right now.Who is allowed to enter?As of July 1, all members of the European Union, as well as Iceland, Norway, Switzerland and Liechtenstein, plan to begin opening their borders to travelers from Algeria, Australia, Canada, Georgia, Japan, Montenegro, Morocco, New Zealand, Rwanda, Serbia, South Korea, Thailand, Tunisia and Uruguay. Residents of Andorra, San Marino, Monaco and the Vatican will also be allowed entry.Are there any exceptions?The restrictions do not apply to health workers, seasonal farm workers, diplomats, humanitarian workers, transit passengers, asylum seekers, students and “passengers traveling for imperative family reasons,” among a handful of other exceptions. The full list of exceptions here.So is Europe out for Americans this summer?Americans can fly to Ireland and Britain. All visitors, however, are required to quarantine for 14 days. Even then, they will probably not be able to travel on to the rest of Europe, unless they can prove they have a residence or immediate family links there.What about U.S. citizens who live in a country on the approved list?The rules are based on the country in which travelers are residents, not their nationalities. So American citizens may be allowed to enter Europe if they live in a country on the approved list. At the same time, citizens of approved countries who reside in the United States may not be allowed entry.Less than four hours before the Paycheck Protection Program was scheduled to close with $130 billion still available for loans to small businesses seeking to maintain their payrolls, the Senate approved extending the application period and allowing small businesses to receive aid until Aug. 8.U.S. ROUNDUPTravelers from California and other hard-hit states are told to quarantine in the Northeast, joining a growing list.ImageA coronavirus test site at Silver Creek High School in San Jose on Tuesday.Credit…Jim Wilson/The New York TimesAs infections surge in the South and the West, the governors of New York, New Jersey and Connecticut — three former hot spots in the Northeast — called on Tuesday for travelers from California and several other states struggling to contain outbreaks to quarantine for 14 days upon reaching their states.Gov. Andrew M. Cuomo of New York, a Democrat, said that visitors from an additional eight states — California, Georgia, Idaho, Iowa, Louisiana, Mississippi, Nevada and Tennessee — would be required to quarantine for 14 days upon arrival in the state. People traveling to New York from Alabama, Arkansas, Arizona, Florida, North Carolina, South Carolina, Texas and Utah had already been told to quarantine.New Jersey and Connecticut are advising travelers from the 16 states to quarantine.It was the latest example of how the shifting geography of the outbreak is once again upending travel regulations. The tristate area’s new restrictions now cover travelers from the nation’s most populous states, and from several of the busiest airports in the country, including those in Atlanta, Los Angeles and Dallas-Fort Worth.In Massachusetts, which had previously required all visitors to quarantine for 14 days, Gov. Charlie Baker, a Republican, announced on Tuesday that beginning on Wednesday, the state would no longer require travelers from Rhode Island, Connecticut, Vermont, New Hampshire, Maine, New York and New Jersey to do so. “Due to lower infection rates across the Northeast region, our administration is updating our state’s travel guidance,” he said.Other places are taking different approaches.Starting July 15, people traveling to Puerto Rico will be required to bring proof of a negative test taken within three days of their arrival, the governor announced Tuesday. Anyone who doesn’t have one will be tested, and those who test positive will have to quarantine for two weeks, and must assume all medical and housing costs.On Monday, the Department of Defense announced that it had lifted travel restrictions for service members to all but three states: California, Florida and Michigan.Over the past week, California’s case count has increased significantly: It now has 231,842 confirmed cases, which have resulted in 6,081 deaths. On Tuesday, in an indication that the state’s hopes of easing more restrictions may be moving further out of reach, Gov. Gavin Newsom said that four more of the state’s 58 counties would likely be added to a “watch list” of places where officials are monitoring troubling trends in hospitalizations and positive tests. Some of the 19 counties on the list as of Tuesday afternoon have already been ordered to shut down bars, and many have paused plans to reopen until they can rein in rising case counts.In other news from around the United States:More than 80 soldiers tested positive for the virus on Monday after three weeks of grueling survival training in North Carolina, according to a current Defense Department official and a former one, who spoke on condition of anonymity. The roughly 110-person class was quickly quarantined at Fort Bragg in North Carolina, but those who tested negative for the virus were allowed to leave, the former official said. The former official said the virus was most likely spread by an Army instructor who tested positive but continued to teach the course, known as Survival, Evasion, Resistance and Escape, or SERE school.As college athletes have returned to campuses for voluntary, organized workouts in June, 33 Division I schools announced more than 200 positive tests from athletes. The outbreaks among football players at Houston, Kansas State and Boise State were deemed severe enough that workouts were shut down. The largest reported outbreak has been at Clemson, where 37 players — nearly one-third of the powerhouse football team’s roster — have tested positive.Treasury Secretary Steven Mnuchin and Jerome H. Powell, the Federal Reserve chair, offered different assessments of how quickly the economy will recover during a congressional hearing on Tuesday afternoon. Mr. Mnuchin said he expected a rebound in the second half of the year while Mr. Powell warned that a surge in cases could set the recovery back and “undermine public confidence, which is what we need to get back to lots of kinds of economic activity that involve crowds.”A U.A.W. union local has asked General Motors to temporarily close an S.U.V. assembly line in Arlington, Texas, as a health measure after a surge of cases in that area. National union officials and G.M. said they were discussing the concerns raised by the local. The factory employs about 4,900 people.‘We need a president’: Biden assails Trump’s response to the virus.Videotranscripttranscript‘We Can’t Continue Like This,’ Biden Says, Assailing Trump’s LeadershipVice President Joseph R. Biden Jr. delivered a speech in Delaware criticizing the Trump administration’s handling of the coronavirus pandemic.Today, we’re facing a serious threat and we have to meet it. We have to meet it as one country. But the president gives no direction, and he pits us against one another. We can’t continue like this — half recovery and half getting worse. We can’t continue — half wearing masks and half rejecting science. We can’t continue — half with a plan and half just hoping for the best. Today, I’m releasing a plan with the steps I believe Donald Trump should undertake immediately to build on the roadmap I released back in March that would have saved lives if it had been adopted. It’s a plan to save lives in the months ahead. Once again, I encourage him to adopt this plan in its entirety. This is too important for politics. First, testing, testing, testing. More testing is not only how you find more cases of coronavirus, Mr. President, it’s how you stop the coronavirus cases. Testing followed by rigorous contact tracing, quarantine and isolation protocols.Vice President Joseph R. Biden Jr. delivered a speech in Delaware criticizing the Trump administration’s handling of the coronavirus pandemic.CreditCredit…Mark Makela for The New York TimesFormer Vice President Joseph R. Biden Jr. opened a new round of attacks on President Trump on Tuesday, condemning the president’s response to the pandemic, his refusal to wear a mask, his handling of intelligence on reports that Russia targeted American troops, and even his “cognitive capability.”Speaking in a high school gym in Wilmington, Del., Mr. Biden, the presumptive Democratic nominee, said “we need a president” — not a “cheerleader.” And he accused Mr. Trump of failing to protect the American people from the virus.The Biden campaign laid out a plan to fight the pandemic as cases rise in many states. It said Mr. Biden would reach out to Dr. Anthony S. Fauci, the nation’s top infectious disease expert, “minutes after he is declared the winner of the election.”“Dr. Fauci will have full access to the Oval Office and an uncensored platform to speak directly to the American people — whether delivering good news or bad,” the plan said.Mr. Biden has made only sporadic in-person appearances since the pandemic upended American daily life, refraining from holding the kinds of rallies that have long been a staple of the campaign trail.“The irony is, I think we’re probably communicating directly, in detail, with more people than we would have otherwise,” he said Tuesday, citing his many virtual appearances. “But I’d much rather be doing it in person.”In the speech, Mr. Biden accused Mr. Trump of having “surrendered” to the virus. He also stressed the importance of wearing a mask in public, something the president has refused to do.“You have a moral obligation,” Mr. Biden said.The virus was circulating in New York as early as February, a new study finds.ImageTimes Square on March 7. Coronavirus antibodies began appearing in blood samples at one hospital in New York in February, scientists reported.Credit…Victor J. Blue for The New York TimesA new study offers the first physical evidence that the coronavirus was circulating at low levels in New York City as early as the first week of February.The city confirmed its first infection on March 1. Mathematical models have predicted that the virus was making its way through the city weeks before then, but the new report is the first to back the conjecture with testing data.The study found that some New Yorkers had antibodies to the virus as early as the week ending Feb. 23. Given the time needed to produce antibodies, those people were most likely infected with the virus about two weeks earlier.“You’re probably talking about very early in February,” said Florian Krammer, an immunologist at the Icahn School of Medicine at Mount Sinai, who led the study. “It looks like there was at least low-level circulation.”The findings were posted online Tuesday and have not yet been vetted by other scientists in a formal review, but several experts said the work was rigorous and credible, if not entirely surprising.Dr. Krammer is continuing to track antibodies in blood samples and plans to do so for at least a year.California prison officials transferred inmates in an attempt to stop an outbreak. It backfired, badly.ImageSan Quentin State Prison in California this week.Credit…Justin Sullivan/Getty ImagesAn effort by California officials to halt the spread of the virus at a prison in Chino backfired and caused a massive outbreak inside San Quentin, the state’s oldest and best-known prison.Late last month, 121 prisoners from the California Institution for Men in Chino, which had nearly 700 cases and nine deaths, were bused to San Quentin, where no inmates were known to have the virus.When they arrived, prisoners’ temperatures were taken and they were placed in a holding area, but no Covid-19 tests were given. The men used the same showers and ate in the same dining hall as other inmates.

What are the symptoms of coronavirus?
Common symptoms include fever, a dry cough, fatigue and difficulty breathing or shortness of breath. Some of these symptoms overlap with those of the flu, making detection difficult, but runny noses and stuffy sinuses are less common. The C.D.C. has also added chills, muscle pain, sore throat, headache and a new loss of the sense of taste or smell as symptoms to look out for. Most people fall ill five to seven days after exposure, but symptoms may appear in as few as two days or as many as 14 days.
What’s the best material for a mask?
Scientists around the country have tried to identify everyday materials that do a good job of filtering microscopic particles. In recent tests, HEPA furnace filters scored high, as did vacuum cleaner bags, fabric similar to flannel pajamas and those of 600-count pillowcases. Other materials tested included layered coffee filters and scarves and bandannas. These scored lower, but still captured a small percentage of particles.
Is it harder to exercise while wearing a mask?
A commentary published this month on the website of the British Journal of Sports Medicine points out that covering your face during exercise “comes with issues of potential breathing restriction and discomfort” and requires “balancing benefits versus possible adverse events.” Masks do alter exercise, says Cedric X. Bryant, the president and chief science officer of the American Council on Exercise, a nonprofit organization that funds exercise research and certifies fitness professionals. “In my personal experience,” he says, “heart rates are higher at the same relative intensity when you wear a mask.” Some people also could experience lightheadedness during familiar workouts while masked, says Len Kravitz, a professor of exercise science at the University of New Mexico.
I’ve heard about a treatment called dexamethasone. Does it work?
The steroid, dexamethasone, is the first treatment shown to reduce mortality in severely ill patients, according to scientists in Britain. The drug appears to reduce inflammation caused by the immune system, protecting the tissues. In the study, dexamethasone reduced deaths of patients on ventilators by one-third, and deaths of patients on oxygen by one-fifth.
What is pandemic paid leave?
The coronavirus emergency relief package gives many American workers paid leave if they need to take time off because of the virus. It gives qualified workers two weeks of paid sick leave if they are ill, quarantined or seeking diagnosis or preventive care for coronavirus, or if they are caring for sick family members. It gives 12 weeks of paid leave to people caring for children whose schools are closed or whose child care provider is unavailable because of the coronavirus. It is the first time the United States has had widespread federally mandated paid leave, and includes people who don’t typically get such benefits, like part-time and gig economy workers. But the measure excludes at least half of private-sector workers, including those at the country’s largest employers, and gives small employers significant leeway to deny leave.
Does asymptomatic transmission of Covid-19 happen?
So far, the evidence seems to show it does. A widely cited paper published in April suggests that people are most infectious about two days before the onset of coronavirus symptoms and estimated that 44 percent of new infections were a result of transmission from people who were not yet showing symptoms. Recently, a top expert at the World Health Organization stated that transmission of the coronavirus by people who did not have symptoms was “very rare,” but she later walked back that statement.
What’s the risk of catching coronavirus from a surface?
Touching contaminated objects and then infecting ourselves with the germs is not typically how the virus spreads. But it can happen. A number of studies of flu, rhinovirus, coronavirus and other microbes have shown that respiratory illnesses, including the new coronavirus, can spread by touching contaminated surfaces, particularly in places like day care centers, offices and hospitals. But a long chain of events has to happen for the disease to spread that way. The best way to protect yourself from coronavirus — whether it’s surface transmission or close human contact — is still social distancing, washing your hands, not touching your face and wearing masks.
How does blood type influence coronavirus?
A study by European scientists is the first to document a strong statistical link between genetic variations and Covid-19, the illness caused by the coronavirus. Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study.
How many people have lost their jobs due to coronavirus in the U.S.?
The unemployment rate fell to 13.3 percent in May, the Labor Department said on June 5, an unexpected improvement in the nation’s job market as hiring rebounded faster than economists expected. Economists had forecast the unemployment rate to increase to as much as 20 percent, after it hit 14.7 percent in April, which was the highest since the government began keeping official statistics after World War II. But the unemployment rate dipped instead, with employers adding 2.5 million jobs, after more than 20 million jobs were lost in April.
How can I protect myself while flying?
If air travel is unavoidable, there are some steps you can take to protect yourself. Most important: Wash your hands often, and stop touching your face. If possible, choose a window seat. A study from Emory University found that during flu season, the safest place to sit on a plane is by a window, as people sitting in window seats had less contact with potentially sick people. Disinfect hard surfaces. When you get to your seat and your hands are clean, use disinfecting wipes to clean the hard surfaces at your seat like the head and arm rest, the seatbelt buckle, the remote, screen, seat back pocket and the tray table. If the seat is hard and nonporous or leather or pleather, you can wipe that down, too. (Using wipes on upholstered seats could lead to a wet seat and spreading of germs rather than killing them.)
What should I do if I feel sick?
If you’ve been exposed to the coronavirus or think you have, and have a fever or symptoms like a cough or difficulty breathing, call a doctor. They should give you advice on whether you should be tested, how to get tested, and how to seek medical treatment without potentially infecting or exposing others.
Now more than 1,000 of the 3,700 prisoners at San Quentin have been infected.A hearing is scheduled on Wednesday in the State Senate, where lawmakers say they have become alarmed about the outbreak and what they describe as a haphazard response by prison officials.Since the pandemic began, California has agreed to release as many as 3,500 inmates up to six months early and is considering more early releases, but the prison system remains at 124 percent capacity, according to state records.Across the United States, the number of prison and jail inmates known to be infected has doubled during the past month to more than 80,000, according to a New York Times database. Nine of the 10 largest known clusters of the virus in the United States are inside correctional institutions, The Times’s data shows.GLOBAL ROUNDUPIn the town where Italy’s first virus victim lived, 40 percent of cases showed no symptoms.ImageCheckpoints were set up along the roads to Vo’ in February.Credit…Andrea Casalis/Andrea Casalis, via Associated PressThree days after a 78-year-old man, Adriano Trevisan, died on Feb. 21 and became the first registered victim of the coronavirus in Italy, the government imposed a 14-day quarantine on Vo’, the small town near Padua where he lived.Backed by the Veneto region, scientists swab-tested nearly all of the town’s 3,275 residents, both at the beginning and at the end of the lockdown.On Tuesday, the results of the study were published in the journal Nature. It found that 42.5 percent of the cases showed no symptoms, indicating that asymptomatic cases might have been important — if unwitting — spreaders of the pandemic, and confirming the importance of widespread testing.The study also found that local outbreaks could be controlled “by combining the early isolation of infected people with community lockdown.”Andrea Crisanti, the top scientific consultant on the virus in Veneto and a professor at the University of Padua and Imperial College London, co-led the study and has been a forceful advocate of widespread testing. He argued in the paper that the Veneto region’s testing and tracing approach had a “tremendous impact on the course of the epidemic in Veneto compared to other Italian regions.”“The experience of Vo’ shows that despite the silent and widespread transmission of SARS-CoV-2, transmission can be controlled,” the authors wrote.The study showed that at the start of the quarantine, 73 residents of Vo’, or 2.6 percent of the population, tested positive for the virus. Two weeks later, that number had dropped to 29 people, eight of which were new cases, but in both rounds of testing, 40 percent of the positive cases had been asymptomatic.Transmission in the absence of symptoms poses clear challenges for the control of Covid-19 without strict social distancing measures or epidemiological surveillance comprising, for instance, a test, trace and isolate strategy, the study noted.In other news from around the world:Prime Minister Narendra Modi of India announced on Tuesday that more than 800 million citizens would receive free food aid through the fall, in a move intended to mitigate hardship for those affected by the virus. Mr. Modi also said that the country’s restrictions, which were first put into effect in late March, would be further eased this week.Airbus announced Tuesday that it would cut 15,000 jobs across its global work force, the largest downsizing in the history of the company. Citing a 40 percent slump in commercial aircraft business activity and an “unprecedented crisis” facing the airline industry, the company said the majority of the layoffs would come from plants in France, Germany, Spain and Britain.Canada extended its ban on most travelers coming from places outside of the United States until July 31. A separate measure barring people coming from the United States is in effect until July 21. Citizens and permanent residents are among the people exempt from both measures.Australia, which showed early signs of quashing the coronavirus, is now battling spikes in its second-most-populous state, Victoria, leading the authorities to announce lockdowns in the greater Melbourne area starting Wednesday night. On Tuesday, Victoria recorded 60 new cases, its 14th consecutive day of double-digit increases. Australia, with a population of 25 million, reported just seven cases in its other states on Tuesday.A new strain of the H1N1 swine flu virus that has been circulating in China should be “urgently” controlled to avoid another pandemic, a team of scientists said in a new study.Airbus plans to cut 15,000 jobs as the pandemic takes a huge toll on air travel.ImageAirbus A350 aircraft at the company’s factory near Toulouse, France, in June.Credit…Stephane Mahe/ReutersThe pandemic continued to wreak havoc on global aviation as the aerospace giant Airbus announced Tuesday that it would cut nearly 15,000 jobs across its global work force, the largest downsizing in the company’s history.Citing a 40 percent slump in commercial aircraft business activity and an “unprecedented crisis” facing the airline industry, Airbus said it would cut around 10 percent of its jobs worldwide, with layoffs hitting operations in France, Germany, Spain and Britain.The chief executive, Guillaume Faury, had been preparing employees for hard times in a series of recent memos in which he warned it would be necessary to adapt to a “lasting decline” in the demand for airliners. The company said Tuesday that it did not expect air travel to return to pre-virus levels before 2023 and potentially not until 2025.“Airbus is facing the gravest crisis this industry has ever experienced,” Mr. Faury said on Tuesday. “We must ensure that we can sustain our enterprise and emerge from the crisis as a healthy, global aerospace leader, adjusting to the overwhelming challenges of our customers.”The layoffs are a stunning reversal of fortune for the world’s largest plane maker, which was founded 50 years ago.The virus reaches an encampment on the Mexican border where migrants wait to apply for asylum in the U.S.ImageMedical staff from Global Response Management took samples from people to test for coronavirus at a migrant encampment in Matamoros, Mexico last month.Credit…Daniel Becerril/ReutersStranded in a crowded encampment along the Mexican border, migrants waiting to apply for asylum in the United States have for months feared that the coronavirus would reach them. This week, the first known case was confirmed among the 2,000 camp dwellers.A 20-year-old woman living at the tent camp in Matamoros, Mexico, has been transferred to an isolation area on the edge of the camp, according to Global Response Management, a nonprofit that runs a clinic there. Two other people at the camp were isolated on June 26 after presenting symptoms of Covid-19, the organization said. Test results are still pending.“The presence of Covid-19 in an already vulnerable population exposed to the elements could potentially be catastrophic,” said Andrea Leiner, the director of strategic planning for Global Response.The encampment sits at the foot of the bridge to Brownsville, Texas, where migrants must go for asylum hearings. They have been subjected to a U.S. policy, known as the Migrant Protection Protocols, that requires asylum applicants to remain in Mexico while applying for asylum, entering the United States only on their court dates.Families of four or five occupy tents intended for two people on a muddy strip of land, with many of the camp residents already weakened by respiratory and gastrointestinal ailments. Migrants bathe and wash their clothes in the Rio Grande.After the coronavirus outbreak, Global Response had expressed concern that hospitals in Matamoros lacked capacity to care for migrants. To date, there have been 1,215 confirmed virus cases in Matamoros and 2,183 cases in Cameron County, Texas, which have both experienced spikes in the last week.The organization’s doctors and nurses in February began distribution of vitamins to boost the immunity of migrants, added dozens of hand-washing stations and checked temperatures. They also erected a field hospital to care for those who fell ill.Local officials in Texas implore the governor to let them issue stay-at-home orders.ImageA health care worker crossing a sky bridge to enter the Dell Seton Medical Center in Austin on Tuesday.Credit…Tamir Kalifa for The New York TimesAs Texas reached a record number of cases on Tuesday, the leaders of its most populous counties have been imploring Gov. Greg Abbott to allow them to issue stay-at-home orders amid the rapidly spreading outbreak.Lina Hidalgo, the executive in Harris County, whose county includes Houston, has issued an advisory to residents to stay at home, but said she needed tools to enforce it.A joint letter sent Monday by the judge in Bexar County and the mayor of San Antonio urged the governor to restore county officials’ power to issue stay-at-home orders and workplace restrictions. Mr. Abbott, a Republican, took away those powers in late April, ahead of the state’s reopening.Samuel T. Biscoe, the judge in Travis County, which includes Austin, sent a similar letter. “The rapid increase in cases has outstripped our ability to track, measure and mitigate the spread,” he wrote.Mr. Biscoe also asked the governor to require face masks. Mr. Abbott has said Texans should wear masks, but he has stopped short of requiring them to do so.The officials, who are all Democrats, also called attention to overloaded local hospitals.The governor had already ordered the postponement of elective procedures in four counties to make room for virus patients. On Tuesday, he extended the order to include four additional counties, this time in south and southwest Texas. The virus has been spreading beyond the major metropolitan areas and into less populous parts of the state.Texas has the fourth-highest case count nationwide, after New York, California and New Jersey, according to a Times database.Also Tuesday, the Texas Medical Association called on the state Republican Party to reconsider its decision to hold an in-person convention in the middle of July in Houston. The state’s Democrats opted to hold their convention online this year.Who needs a gym?Here are some tips for working out in your local park, backyard or living room.
