With public health officials warning of a long fight ahead, the virus has changed the world’s capacity to immunize against other diseases and redefined summer vacation for much of the world.With public health officials warning of a long fight ahead, the virus has changed the world’s capacity to immunize against other diseases and redefined summer vacation for much of the world.
The impact on the prevention of other infectious diseases is becoming increasingly obvious, with Africa and Asia reporting a huge slide in the number of people reached through vaccine programs as a result of the pandemic and restrictions used to combat it. That could set the stage for another looming health crisis, officials say.The impact on the prevention of other infectious diseases is becoming increasingly obvious, with Africa and Asia reporting a huge slide in the number of people reached through vaccine programs as a result of the pandemic and restrictions used to combat it.

Much of Europe is preparing for a summer of squashed or severely limited travel plans, with Germany announcing an extension of its worldwide travel warning until mid-June. But other countries, like Croatia, which rely heavily on tourism to boost their economy are trying to salvage the summer season and have suggested they will allow in tourists from countries with a low number of coronavirus infections.Much of Europe is preparing for a summer of squashed or severely limited travel plans, with Germany announcing an extension of its worldwide travel warning until mid-June.

Even the nature of citizens’ relationship with their states has come into question. In France, the government’s failure to stem the initial outbreak has undermined the social contract, critics say, threatening the stability of the country’s strong central government.Even the nature of citizens’ relationship with their states has come into question.

“We have some of the highest taxes and biggest public spending in the world, and the French people accept that because, implicitly, their protection was guaranteed by the state,” said Pierre Vermeren, a historian who teaches at the University of Paris 1 Panthéon-Sorbonne.“We have some of the highest taxes and biggest public spending in the world, and the French people accept that because, implicitly, their protection was guaranteed by the state,” said Pierre Vermeren, a historian who teaches at the University of Paris 1 Panthéon-Sorbonne.
In the United States, gross domestic product, the broadest measure of goods and services produced in the economy, fell at a 4.8 percent annual rate in the first quarter of the year, the Commerce Department said on Wednesday, the worst quarterly contraction since the 2008 recession. The worst is yet to come, experts say, with figures from the current quarter expected to show G.D.P. contracting at an annual rate of 30 percent or more.In the United States, gross domestic product, the broadest measure of goods and services produced in the economy, fell at a 4.8 percent annual rate in the first quarter of the year, the Commerce Department said on Wednesday, the worst quarterly contraction since the 2008 recession.

A couple of baguettes tucked under her arm, Maha Rambousek fiddled with a face mask that kept sliding off her nose. After a local decree made masks mandatory in public, she had quickly stitched it together, but was left confused when the policy was overturned two days later by the central government.A couple of baguettes tucked under her arm, Maha Rambousek fiddled with a face mask that kept sliding off her nose.

While France’s vaunted health care system has staved off disaster, France has suffered the world’s fourth-biggest death toll — now at 23,293 official deaths, behind the United States, Italy and Spain — a consequence, critics say, of the central government’s failure to anticipate the onslaught of the contagion.While France’s vaunted health care system has staved off disaster, France has suffered the world’s fourth-biggest death toll — now at 23,293 official deaths, behind the United States, Italy and Spain — a consequence, critics say, of the central government’s failure to anticipate the onslaught of the contagion.
That failure and a critical shortage of masks and testing kits — also resulting from gaps in state policies — led to the virus’s rapid early spread, prompting France to impose one of the word’s strictest nationwide lockdowns, now in its seventh week.That failure and a critical shortage of masks and testing kits — also resulting from gaps in state policies — led to the virus’s rapid early spread, prompting France to impose one of the word’s strictest nationwide lockdowns, now in its seventh week.
Prime Minister Édouard Philippe announced a tentative plan on Monday to gradually reopen the country starting on May 11. Schools and businesses would start reopening, though not restaurants or cafes. He urged companies to keep their employees working at home.

Adding to growing evidence that the novel coronavirus can spread through air, scientists have identified genetic markers of the virus in airborne droplets, many with diameters smaller than one-ten-thousandth of an inch.
That had been previously demonstrated in laboratory experiments, but now Chinese scientists studying real-world conditions report that they captured tiny droplets containing the genetic markers of the virus from the air in two hospitals in Wuhan, China, where the outbreak started.
Their findings were published Monday in the journal Nature.
It remains unknown if the virus in the samples they collected was infectious, but droplets that small, which are expelled by breathing and talking, can remain aloft and be inhaled by others.
“Those are going to stay in the air floating around for at least two hours,” said Linsey Marr, a professor of civil and environmental engineering at Virginia Tech who was not involved with the Nature paper. “It strongly suggests that there is potential for airborne transmission.”
Dr. Marr and many other scientists say evidence is mounting that the coronavirus is being spread by tiny droplets known as aerosols. The World Health Organization has so far downplayed the possibility, saying that the disease is mostly transmitted through larger droplets that do not remain airborne for long, or through the touching of contaminated surfaces.
Even with the new findings, the issue is not settled. Although the coronavirus RNA — the genetic blueprint of the virus — was present in the aerosols, scientists do not know yet whether the viruses remain infectious or whether the tests just detected harmless virus fragments.

“We are tracking significant amounts of new trafficking activity in multiple countries, which seems to indicate that traffickers are both still very much in operation and also actively seeking ways to adapt and thrive in the new normal,” said Tim Wittig, the head of intelligence for United for Wildlife, a nonprofit led by Prince William to fight wildlife trafficking.“We are tracking significant amounts of new trafficking activity in multiple countries, which seems to indicate that traffickers are both still very much in operation and also actively seeking ways to adapt and thrive in the new normal,” said Tim Wittig, the head of intelligence for United for Wildlife, a nonprofit led by Prince William to fight wildlife trafficking.
In a report published earlier this month, Dr. Wittig also found that temporary disruptions to the trade would be fleeting. “Traders have incentive to move product as soon as is feasible,” he said.In a report published earlier this month, Dr. Wittig also found that temporary disruptions to the trade would be fleeting. “Traders have incentive to move product as soon as is feasible,” he said.

While African countries have made incredible improvements in immunizing children, the continent still lags behind when it comes to meeting global vaccination targets. The causes include the difficulty for health workers to access some areas, inadequate public campaigns and lack of trust of vaccines from some.While African countries have made incredible improvements in immunizing children, the continent still lags behind when it comes to meeting global vaccination targets.

Simon Property Group, the mall operator, hopes its game plan for reopening shopping centers will be enough to fend off that possibility. When the centers begin reopening on Friday, security officers and employees will “actively remind and encourage shoppers” to stay away from others and to refrain from shopping in groups. Food court seating will be spaced apart, and reusable trays will be banished. In restrooms, every other sink and urinal will be taped off.Simon Property Group, the mall operator, hopes its game plan for reopening shopping centers will be enough to fend off that possibility.

A memo from the company provides a glimpse of how the broader American shopping experience is likely to look as the country begins to slowly reopen. But the success of such an approach depends largely on whether retailers will also decide to reopen stores and whether the public will feel comfortable going to malls when tests for the virus remain difficult to get.A memo from the company provides a glimpse of how the broader American shopping experience is likely to look as the country begins to slowly reopen.

Because Greece has tested a very small percentage of its population, it is impossible to know how extensively the virus has spread in the country. But its total deaths have been low — 138 in a population of about 10.7 million — a surprise to experts, especially given the elderly population.

Iran is not only awash in unsold oil because of American sanctions and the global glut caused by the coronavirus.

The chick mass grave created an uproar among Iranians, and many blamed it on what they called the government’s lack of oversight.

Spectacular waves more than 25 feet high barreled on Tahiti’s famed Teahupo’o reef that day a month ago. Audible from miles away, Teahupo’o — home of the 2024 surfing events of the Paris Olympics — normally echoes like thunderous Morse code, calling in the best surfers from every corner of the globe. They would have buzzed to the reef by the dozen, spilling out of boats and riding Jet Skis to tow into waves as film crews in helicopters circled above.Spectacular waves more than 25 feet high barreled on Tahiti’s famed Teahupo’o reef that day a month ago.

It made me feel like I’d jumped in a time machine and landed in a time before surfing.”Something similar happened as a southern swell broke at Pleasure Point in Santa Cruz County, Calif., on April 9, the first day of what would be a weeklong beach ban. “All we could do was stand there and watch it break,” said Kyle Thiermann, a professional surfer. “On a day that good, usually there are 100 surfers in the water.
