Coronavirus Variant Found in India is Renamed Delta

If you haven’t yet mastered the name of the latest variant of the coronavirus to turn nations upside down – B.1.617.2, as evolutionary biologists call it – then don’t worry: the World Health Organization has proposed a solution.

The group said Monday that it had developed a less technical and easier-to-pronounce system for naming variants – the mutated versions of the virus that have sparked new flare-ups around the world.

Variants are assigned to letters of the Greek alphabet in the order in which they are classified as a potential threat by the WHO

For example, B.1.617.2, which contributed to a fatal increase in India, was named Delta in the new system. This variant can spread even faster than B.1.1.7, the variant discovered in the UK that has contributed to devastating waves of cases around the world. (The new name of B.1.1.7 is Alpha.)

Scientists are constantly adding long sequences of letters and numbers to new variants for their purposes, but hope that Greek letters will roll off the tongue of non-scientists more easily.

There is also a deeper motivation: The letter-number system was so complicated that many people instead referred to variants with the locations where they were discovered (e.g. the Indian variant for B.1.617.2). Scientists fear these informal nicknames can be both inaccurate and stigmatizing, penalizing countries for investing in the genome sequencing necessary to sound the alarm of new mutations that may have surfaced elsewhere.

Whether the Greek letters stick is another question. It has been months since experts convened by the WHO started debating the issue, spreading labels like “the British variant” and “the South African variant” in the news media.

The experts said they considered a number of alternatives, such as taking syllables from existing words to form new words. But too many of those syllable combinations are already recognizable names of places or companies, they said.

Incidentally, the Greek letters had just been relieved of another task: the World Meteorological Organization announced in March that it would no longer use them to name hurricanes.

UK instances of Covid variant recognized in India double in a single week

Cases of the Covid-19 variant first identified in India have more than doubled in England within one week, the country’s health authority said.

The number of cases of the strain had reached 6,959 by Wednesday, an increase of 3,535 cases from the previous week.

The B.1.617.2 variant, a highly contagious triple-mutant strain of the coronavirus, is likely to be more transmissible than the variant first identified in England last fall, Public Health England said Thursday.

Bolton, Bedford and Blackburn were the most affected areas in England, according to PHE, although it said there were small numbers of cases of the variant in most parts of the country.

Hospitalizations were also rising in some areas, PHE added, noting that most hospital admissions were in unvaccinated people.

Research published by PHE last week showed that two doses of Covid vaccines gives people high levels of protection against the B.1.617.2 strain.

Jenny Harries, CEO of the U.K. Health Security Agency, said in PHE’s weekly update that the public should continue to act with caution as Britain eases lockdown restrictions.

“We now know that getting both vaccine doses gives a high degree of protection against this variant and we urge everyone to have the vaccine,” she said.

“Make sure that you remain careful, work from home if you can, meet people outside where possible and remember ‘hands, face, space, fresh air’ at all times.”

The U.K. has begun to tentatively lift lockdown restrictions in recent months, with the government hoping to remove all measures by June 21.

However, Prime Minister Boris Johnson has warned that the country “may need to wait” for a complete return to normality, although he told the BBC on Thursday there was nothing “currently in the data” to suggest the June unlocking would be derailed.

Johnson announced earlier this month that the U.K. would accelerate second vaccine doses for the over-50s and clinically vulnerable in an effort to combat the spread of the B.1.617.2 strain.

More than 62.6 million vaccines had been given in the U.K. by May 26, with 73% of the adult population having received their first dose. Almost half of British adults have been fully vaccinated with both doses.

On May 22, 883 people were in hospital with Covid-19 in the U.K. — a huge drop from January’s peak of 39,249.

Two doses of Covid vaccines present safety in opposition to India variant

A new study has found that two doses of either the Pfizer-BioNTech or AstraZeneca-University of Oxford vaccine give effective protection against the Covid variant first discovered in India, however it underscored the need for two doses, as both vaccines were significantly less effective after only one shot.

The study, led by Public Health England, also found that two doses of one of those vaccines were similarly as effective at protecting against the variant that first emerged in the U.K. and has since become a dominant strain in the West.

Dr. Jenny Harries, CEO of the U.K. Health Security Agency, told the BBC that the study provided the “first real-world evidence of vaccine effectiveness” against the variant first identified in India.

Conducted between April and May, the research found that the Pfizer-BioNTech vaccine was 88% effective against symptomatic disease from the B.1.617.2 Covid variant — a subtype of a variant that emerged in India last fall which has since spread to Europe — two weeks after the second dose. The vaccine was 93% effective two weeks after the second dose against the B.1.1.7 variant. which was first discovered in the U.K. last fall.

Meanwhile, two doses of the AstraZeneca vaccine were found to be 60% effective against symptomatic disease from the B.1.617.2 variant from India, compared with 66% effective against the strain from the U.K.

“Vaccine effectiveness against symptomatic disease from the B.1.617.2 variant is similar after 2 doses compared to the B.1.1.7 (Kent) variant dominant in the U.K., and we expect to see even higher levels of effectiveness against hospitalisation and death,” the study authors wrote. The results were published Saturday as a preprint and the study has not yet been peer-reviewed.

PHE said the difference in effectiveness between the vaccines after two doses “may be explained by the fact that rollout of second doses of AstraZeneca was later than for the Pfizer-BioNTech vaccine, and other data on antibody profiles show it takes longer to reach maximum effectiveness with the AstraZeneca vaccine.”

However, both vaccines were only 33% effective against symptomatic disease from B.1.617.2 three weeks after the first dose. In the same time frame, they were found to be 50% effective against the B.1.1.7 variant.

Variant of concern

The variant first discovered in India has been blamed for causing a dramatic third wave of infections in the country, overwhelming hospitals and causing thousands of deaths this spring. There were concerns that Covid vaccines could be rendered less effective by the variant so the latest data should help allay those worries.

The India variant has been detected in numerous other countries now, according to the World Health Organization, which dubbed it a “variant of concern” in early May.

The PHE study analyzed data from 1,054 people, of all age groups and several ethnicities, confirmed as having the B.1.617.2 variant through genomic sequencing. The data was collected from April 5 and hence covers the period since the B.1.617.2 variant (one of three variant subtypes found in India) emerged in parts of the U.K.

“As with other variants, even higher levels of effectiveness are expected against hospitalisation and death. There are currently insufficient cases and follow-up periods to estimate vaccine effectiveness against severe outcomes from the B.1.617.2 variant. PHE will continue to evaluate this over the coming weeks,” the study’s authors added.

Responding to the study, the U.K.’s health secretary, Matt Hancock, described the findings as “groundbreaking – and proves just how valuable our Covid-19 vaccination programme is in protecting the people we love.”

The U.K. has given more than 22 million people two doses of a Covid vaccine, while 72% of the population (or almost 40 million people) have had one shot, government data shows.

Hancock said the latest data emphasized “how important the second dose is to secure the strongest possible protection” against Covid-19 and its variants.

Separate PHE analysis indicated that the country’s Covid-19 vaccination program has so far prevented 13,000 deaths and around 39,100 hospitalizations in older people in England, up to May 9.

Singapore rejects Delhi chief’s claims about new Covid-19 variant

SINGAPORE – Singapore has ordered Facebook, Twitter, and a local publisher to correct a false statement that implies a new variant of coronavirus from the city-state that is at risk of spreading to India.

Singapore Health Minister Ong Ye Kung instructed the two social media giants and SPH magazines to provide a correction notice to their users in Singapore. SPH Magazines has a popular forum called HardwareZone.

“There is no new” Singapore “variant of Covid-19. There is also no evidence of a Covid-19 variant that is” extremely dangerous “for children,” said the Singapore Ministry of Health.

“The strain that prevails in many of the Covid-19 cases discovered in Singapore in recent weeks is variant B.1.617.2, native to India,” he added. “The existence and distribution of variant B.1.617.2 in India goes back to the discovery of the variant in Singapore. This was publicly known and reported by various media on May 5, 2021.”

The Covid variant B.1.617 was detected for the first time in India last year. The World Health Organization recently named the B.1.617 a “worrying variant”, indicating that it has become a global health threat.

What happened?

The move from Singapore came after unsubstantiated comments by an Indian politician sparked a diplomatic incident between the two countries earlier this week.

The chief minister of Delhi, Arvind Kejriwal, tweeted on Tuesday that a new coronavirus variant in Singapore is said to be extremely dangerous for children and could lead to a third wave in India. He has provided no evidence to support his claims.

What was the reaction like?

Kejriwal was publicly reprimanded by the foreign ministers of both countries.

“Politicians should stick to the facts! There is no such thing as a ‘Singapore variant’,” said Vivian Balakrishnan, Singapore’s foreign minister, in a tweet in response to Kejriwal’s claim.

The Singapore Foreign Ministry said Wednesday it regretted Kejriwal’s “unsubstantiated claims”.

“MFA is disappointed that a prominent political figure did not establish the facts before making such allegations. MFA met with Indian High Commissioner P Kumaran this morning to express those concerns,” the State Department said.

India’s Foreign Minister Subrahmanyam Jaishankar said the two countries are “solid partners” in the fight against the pandemic.

“Irresponsible comments from those who should know better, however, can harm long-term partnerships. Let me be clear – Delhi CM doesn’t speak for India,” he said on Twitter. Jaishankar was previously India’s High Commissioner in Singapore.

Indian Minister of Civil Aviation Hardeep Singh Puri responded to Kejriwal’s comments on Twitter, noting that international flights to India have been suspended since March 2020.

He also pointed out that India and Singapore have no air travel bubble and that New Delhi only operates return flights from the city-state to bring back stranded Indians.

“Even so, we are keeping an eye on the situation. Every precaution is being taken,” Puri said, according to a CNBC translation of his remarks in Hindi.

Covid in India and Singapore

There was recently a surge in locally submitted cases in Singapore, prompting the government to tighten social restrictions again.

While a number of children in the city-state were recently infected with Covid-19, Education Minister Chan Chun Sing said on Sunday that none of them are seriously ill, but the situation is still worrying, according to the Straits Times.

Nonetheless, Singapore announced on Tuesday that children between the ages of 12 and 15 could be vaccinated.

So far, Singapore has reported more than 61,600 cases and 31 deaths, according to Johns Hopkins University.

India is the second worst infected country in the world after the US and is facing a devastating second wave. To date, India has reported more than 25 million cases and over 287,000 deaths, but experts believe the numbers have been severely under counted.

Delhi was one of the hardest hit regions in the country, with hospitals facing shortages of hospital beds, oxygen supplies and drugs to treat Covid-19 patients.

Covid variant from India might grow to be dominant within the UK

LONDON – The variant of coronavirus, which first appeared in India, could become the dominant strain of the virus in the UK in a matter of days, scientists have warned.

Great Britain is noticing a rapid spread of the Covid variant “B.1.617”, which first appeared in India last October and is considered to be responsible for a wave of infections that has hit the South Asian nation in recent months.

B.1.617 has three sublines, each with slightly different mutations, according to the World Health Organization. Variant B.1.617 was named a “variant of concern” by the WHO last week and on May 7 the UK named subline B.1.617.2 a variant of concern. Since then, the UK has seen almost double cases caused by the variant.

On Monday, UK Health Secretary Matt Hancock informed UK lawmakers that 2,323 cases of variant B.1.617.2 had been confirmed in the UK, up from 1,313 last Thursday. He said 483 of those cases were spotted in coronavirus outbreaks in the northern English cities of Bolton and Blackburn, where he said it has become the dominant burden as cases there doubled in the past week and “increased across all age groups.” “- although hospital stays were stable. There are now 86 local authorities with five or more confirmed cases, Hancock added.

The UK has introduced “surge vaccinations” in the hardest hit areas to protect as many people as possible from the virus and variant, which initial evidence suggests is more transmissible.

Early data shows that the Covid vaccines currently in use are still effective against the new variant, a government official said on Monday, although there is now a race to vaccinate younger age groups and anyone who has not previously accepted the vaccine.

There are already concerns within the government that the UK’s target date for ending all restrictions on social contact, June 21, may be reconsidered amid the proliferation of the new variant.

Experts are sounding the alarm that it is likely that the variant is already anchored. Paul Hunter, a professor of medicine at the University of East Anglia, told the Guardian newspaper on Monday that the India variant could overtake a more transmissible variant of Covid (known as B.1.1.7)) This occurred in the UK last fall and has become a dominant strain in the country and other parts of the world.

“There is no evidence that the recent rapid increase in the B.1.617.2 variant shows any signs of slowing,” he told the newspaper. “This variant will overtake (the Kent variant) and become the dominant variant in the UK for the next few days if it has not already done so.”

How serious is it

That the variant poses potential problems for the UK, a country with a high Covid vaccination rate (nearly 70% of the adult population had at least one dose of vaccine and nearly 40% had two doses), is not a good sign for other countries that are continuing their vaccination programs lag behind, especially in Europe.

The WHO has said that the Indian variant has been discovered in all European countries. By May 11, variant B.1.617 had been discovered in 44 countries in all six WHO regions, the organization announced in its last weekly update.

A panel of experts noted in the British Medical Journal on Monday that “there are many things we know and many things we do not know about variant B.1.617.2” but that “we know enough to say that this is new variant could be very serious. “

“We know that it is spreading rapidly (doubling roughly every week in the UK and nearly tripling from 520 to 1,313 cases last week) that it is establishing itself in a number of areas across the country,” wrote Dr. Stephen Reicher of the University of St. Andrews and Dr. Susan Michie and Dr. Christina Pagel from University College London, who are experts in advisory groups (SAGE and Independent SAGE) that provide scientific advice to the government.

“Compared to the dominant variant B.1.1.7, we know that B.1.617.2 is very likely to be more transmissible and possibly better transmitted between people who are fully vaccinated,” they added.

“We don’t yet know how much of the faster transmission is due to the characteristics of the variant itself as opposed to the characteristics of the infected, and … we do not yet know if and to what extent the new variant undermines the ability of vaccines to protect us from infection, hospitalization and death, or prevent us from passing infections on to others, “they added.

They found that SAGE’s worst-case scenario modeling suggests that if B.1.617.2 were 40-50% more transferable than variant B.1.1.7, it would lead to an increase in hospital admissions that could be worse than January 2021, “and also escapes The more vaccines, the higher the level could be.”

For now, however, they warned that “we don’t know enough to know exactly how serious it would be if it became the dominant line in the UK”.

UK lifts lockdown however India Covid variant threatens June 21 easing

The UK continued easing restrictions on its economy and social contact on Monday, but the spread of the variant of Covid, which first appeared in India, threatens a total lifting of the measures.

From Monday, pubs, bars and restaurants will be able to serve customers inside. Museums, cinemas and theaters can be reopened; and exercise classes and indoor sports can be resumed. In addition, up to six people or two households can socialize indoors, and gatherings of up to 30 people are allowed outdoors.

International travel can also be resumed on Monday if people are allowed to participate in foreign holidays. Countries have been put on a “green”, “amber” or “red” list – with different quarantine rules for returning to the UK – determined by their infection rate.

While the reopening is a sigh of relief for the hospitality, leisure and travel industries, the lifting of restrictions will be tempered by a surge in Covid cases attributed to a variant of the coronavirus that first emerged in India.

British Prime Minister Boris Johnson called for a cautious approach to the reopening, warning that the proliferation of the new variant could threaten further easing on June 21 in hopes that all restrictions on social contact would be lifted.

On Friday, Johnson said there is currently no evidence that the variant is dodging Covid vaccines used across the country, but that the new variant “could seriously disrupt our progress … and I must stress that we will do this. ” whatever it takes to protect the public. “

He said the variant was more transmissible than other strains but cautioned it wasn’t clear by how much. UK Chief Medical Officer Chris Whitty speaks next to Johnson, added that there was “confidence” that the strain was “more transferable” than other variants already circulating in the country.

In cases rise

The new variant is also believed to be more transferable than a variant that first launched in the UK last fall. This became the dominant strain in the country, along with the US and parts of Europe.

On Sunday, the UK reported just over 1,900 new cases, bringing the total number of infections registered in the UK to 4,450,777. As of Sunday, 15,918 cases had been reported in the past seven days, an 8.6% increase over the May 3-9 period, according to government figures.

This surge in cases has led the government to change its vaccination strategy. Those over 50 and those at risk will receive their second dose eight weeks after the first dose rather than 12 weeks according to the previous vaccination strategy.

It was announced on Friday that the UK would be running vaccinations and testing in areas where the new variant of Covid, first discovered in India, is spreading.

To date, nearly 70% of the UK adult population have received a first dose of a coronavirus vaccine, while just over 38% have received two doses. This UK reached the milestone on Sunday of giving 20 million people a second dose of a Covid shot.

UK Health Secretary Matt Hancock said the government would make a decision on June 14 whether to finally lift the restrictions a week later. Speaking to Sky News on Sunday, Hancock said variants are one of the “greatest risks to this opening”.

“Because of the speed of transmission, it can really spread like wildfire among the unvaccinated groups. So it is important to vaccinate as many people as possible, especially those most susceptible to hospitalization.”

Britain Altering Protocols to Fight Virus Variant

Credit…Justin Tallis/Agence France-Presse — Getty Images

LONDON — Prime Minister Boris Johnson of Britain said on Friday that vaccination protocols would be changed to swiftly deliver second doses to people over 50-years-old to combat the spread of a coronavirus variant first detected in India, a warning sign for countries that are easing restrictions even though their own vaccination campaigns are incomplete.

“We believe this variant is more transmissible than the previous ones,” Mr. Johnson said. What remained unclear, he said, was by how much. The infectiousness of the variant first detected in India remains the subject of intense study and some leading experts have said it is too early to assess its transmissibility.

If it proves significantly more transmissible, he said, “we face some hard choices.” He added that there was no evidence that the variant was more likely to cause serious illness and death, and there was no evidence to suggest vaccines were less effective against the variant in preventing serious illness and death.

While he said the country would not delay plans to ease restrictions on Monday, he warned that the spread of the variant could force the government to change course.

“This new variant could pose a serious disruption to our progress,” he said at a news conference on Friday.

The numbers of cases involving the variant, known as B.1.617, rose from 520 last week to 1,313 cases this week in Britain, according to official statistics.

The extent to which the variant has spread globally is unclear, because most countries lack the genomic surveillance capabilities employed in England.

That surveillance capability has allowed health officials in Britain to spot the rise of concerning variants more quickly than other nations, offering an early warning system of sorts as a variant seen in one nation almost invariably pops up in others.

Most cases detected in Britain are in northwestern England. The focus has been on Bolton, a town of nearly 200,000 that has one of the country’s highest rates of infection and where health officials have warned of widespread community transmission of the B.1.617 variant. Some cases have also been reported in London. The rapid spread of the variant has led officials to debate speeding up dosing schedules and opening up access to shots in hot spots to younger age groups.

National restrictions in England are scheduled to be eased on Monday, with indoor dining and entertainment returning, before a full reopening in June. But officials have cautioned that those plans might be in danger.

In Scotland, First Minister Nicola Sturgeon said on Friday that plans to ease restrictions in Glasgow would be delayed at least a week out of concern about an uptick in cases that officials said may be being driven by the variant.

Much is unknown about the new variant, but scientists fear it may have driven the rise of cases in India and could fuel outbreaks in neighboring countries.

Dr. Maria Van Kerkhove, the technical lead of the World Health Organization’s coronavirus response, said a study of a limited number of patients, which had not yet been peer-reviewed, suggested that antibodies from vaccines or infections with other variants might not be quite as effective against B.1.617. The agency said, however, that vaccines were likely to remain potent enough to provide protection from serious illness and death.

British officials have said the variant appears to be more contagious than the B.1.1.7 variant, which was detected last year in Kent, southeast of London and swept across Britain in the winter, forcing the country into one of the world’s longest national lockdowns. The B.1.1.7 variant has now been found in countries around the world.

In the United States, the B.1.1.7 variant did become the predominant version of the virus, now accounting for nearly three-quarters of all cases. But the U.S. surge experts had feared ended up a mere blip in most of the country. The nationwide total of daily new cases began falling in April and has now dropped more than 85 percent from the horrific highs of January.

The B.1.617 variant has been found in virus samples from 44 countries and was designated a variant of concern by the W.H.O. this week, which means there is some evidence that it could have an impact on diagnostics, treatments or vaccines and needs to be closely monitored.

Christina Pagel, a member of a group of scientists advising the government, known as SAGE, said postponing next week’s reopening would avoid “risking more uncertainty, more damaging closures and longer recovery from a worse situation.”

“We need to learn from previous experience,” Dr. Pagel, the director of the Clinical Operational Research Unit at University College London, said on Twitter.

Britain briefly reopened its economy at the end of last year, only to abruptly impose new restrictions that remained in place for months as it fought a deadly wave of infections.

In an attempt to offer at least partial protection to as many people as quickly as possible, Britain spaced injections between doses for two-stage coronavirus vaccines up to 12 weeks after the first vaccines were approved in December. That was far longer than the three- or four-week interval employed by most other countries.

Mr. Johnson said that those older than 50 will now be able to get second doses after eight weeks.

“It is more important than ever that people get the additional protection of a second dose,” he said.

The speedy rollout saved at least 11,700 lives and prevented 33,000 people from becoming seriously ill in England, according to research released by Public Health England on Friday.

Infections, serious illness and deaths have plummeted across Britain. Only 17 deaths were reported on Friday.

But the vaccination campaign has slowed down since last month because of supply shortages and the need to start distributing second doses. The number of daily first doses on average last month was 113,000, far below the average of 350,000 daily doses administered in March.

Only those over 38-years-old are currently eligible for vaccination.

It remains unclear whether the country has the vaccine supplies on hand to move rapidly to surge more into communities around the country to speed up vaccinating younger age groups.

Where states are reporting vaccines given

Minnesota’s statewide mask mandate is over. But in Minneapolis, the state’s largest city, face coverings are still required.

In Michigan, Kentucky and Oregon, governors cheerily told vaccinated people that they could go out maskless. But mask mandates remained in force for New Yorkers, New Jerseyans and Californians.

So unexpected was new federal guidance on masks that in Kansas City, Mo., Mayor Quinton Lucas went from saying he would not change his mask order, to saying he would think about it, to announcing that he was getting rid of it altogether, all in the span of about seven hours.

Across the country, governors, store owners and people running errands were scrambling on Friday to make sense of the abrupt change in federal guidelines, which said fully vaccinated people could now safely go most places, indoors or outdoors, without a mask.

At least 20 states that still had mask mandates in place this week said by Friday evening that they would exempt fully vaccinated people or repeal the orders entirely, while at least five others with mask requirements had not announced any changes. The rapidly changing rules brought an end to more than a year of mandatory masking in much of the country, even as some said they were not yet ready to take off their face coverings.

“I’m going to wear a mask for a long time to come,” said Fanny Lopez, 28, who was grocery shopping in San Antonio on Friday morning while wearing a black cloth mask. “I trust the mask more than the vaccine. The government messages are confusing, telling us to wear a mask one day and the next day no.”

The sudden shift in public health advice resonated at every level of government, from City Hall in Hartsville, S.C., where a local mask mandate was allowed to expire, to Nevada’s Gaming Control Board, which said it was not practical “to attempt to enforce a mask mandate tethered to an individual’s vaccination status,” to the U.S. Capitol, where the attending physician said House members would still have to cover their faces on the floor of the chamber.

But the shift was perhaps most challenging for governors and big-city mayors, many of whom have expended significant political capital on mask orders in the face of protests and lawsuits, and who were not given a heads-up about the change in federal policy before it was announced on Thursday.

Mayor Lucas said he could not keep Kansas City’s order in place since there was no easy way to differentiate people who are fully vaccinated — now 36 percent of Americans — from the 64 percent who are not.

“While I understand the C.D.C.’s theory that they could just create a rule that says vaccinated folks go anywhere without a mask, and everybody else who’s unvaccinated will follow it, I don’t know if that’s the type of rule that was written in coordination with anyone who has been a governor or a mayor over the last 14 months,” said Mr. Lucas, a Democrat.

The new guidance from the Centers for Disease Control and Prevention, which came amid a steep drop in new cases and an expansion of vaccine eligibility to everyone 12 and older, signaled a shift toward pre-pandemic social norms, when no one thought twice about buying groceries or sitting down in their cubicle with a bare mouth and nose. Walmart announced on Friday that fully vaccinated employees and customers would no longer need to wear masks, and Costco issued a similar announcement.

“At least 20 times today I kept grabbing my short pockets looking for my face mask,” said Erik Darmstetter, who is fully vaccinated and owns Office Furniture Liquidations in San Antonio. “It wasn’t there. I keep forgetting we don’t need it anymore.”

Others were moving more slowly. Gov. Phil Murphy of New Jersey, a Democrat, said he would keep his state’s mask mandate in place, writing on Twitter that “we’re making incredible progress, but we’re not there yet.” And Gov. Charlie Baker of Massachusetts, a Republican, indicated he would revisit his state’s rules next week, but he did not announce any immediate changes.

When asked on Friday about how the C.D.C.’s guidelines would affect Mr. Biden’s executive order requiring masks on federal property, Jen Psaki, the White House press secretary, said at a news conference that it “may take a couple of days” to adopt the agency’s advice. She added that there are no plans to change the federal order mandating masks on public transportation.

On the question of possible vaccine passports, Ms. Psaki said the administration was prioritizing remained focused on the vaccination campaign, and that the administration was “not currently considering federal mandates,” and did not have plans to change its approach.

“We also understand that private sector companies may decide that they want to have requirements. That’s up to them to make that determination,” she said.

BUENOS AIRES — For most of the past year, Uruguay was held up as an example for keeping the coronavirus from spreading widely as neighboring countries grappled with soaring death tolls.

Uruguay’s good fortune has run out. In the last week, the small South American nation’s Covid-19 death rate per capita was the highest in the world, according to data compiled by The New York Times.

As of Wednesday, at least 3,252 people had died from Covid-19, according to the Uruguayan Health Ministry, and the daily death toll has been about 50 during the past week.

Six out of the 11 countries with the highest death rates per capita are in South America, a region where the pandemic is leaving a brutal toll of growing joblessness, poverty and hunger. For the most part, countries in the region have failed to acquire sufficient vaccines to inoculate their populations quickly.

Contagion rates in Uruguay began inching up in November and soared in recent months, apparently fueled by a highly contagious variant first identified in Brazil last year.

“In Uruguay, it’s as if we had two pandemics, one until November 2020, when things were largely under control, and the other starting in November, with the arrival of the first wave to the country,” said José Luis Satdjian, the deputy secretary of the Health Ministry.

The country with the second-highest death rate per capita is nearby Paraguay, which also had relative success in containing the virus for much of last year but now finds itself in a worsening crisis.

Experts link the sharp rise in cases in Uruguay to the P.1 virus variant detected in Brazil.

“We have a new player in the system and it’s the Brazilian variant, which has penetrated our country so aggressively,” Mr. Satdjian said.

Uruguay closed its borders tightly at the beginning of the pandemic, but towns along the border with Brazil are effectively binational and have remained porous.

The outbreak has strained hospitals in Uruguay, which has a population of 3.5 million.

On March 1, Uruguay had 76 Covid-19 patients in intensive care units. This week, medical professionals were caring for more than 530, according to Dr. Julio Pontet, president of the Uruguayan Society of Intensive Care Medicine who heads the intensive care department at the Pasteur Hospital in Montevideo, the capital.

That number is slightly lower than the peak in early May, but experts have yet to see a steady decline that could indicate a trend.

“It is still too early to reach the conclusion that we’ve already started to improve, we’re in a high plateau of cases,” Dr. Pontet said.

Despite the continuing high number of cases, there is optimism that the country will be able to get the situation under control soon because it is one of the few in the region that has been able to make quick progress on its vaccination campaign. About a quarter of the population has been fully immunized.

“We expect the number of serious cases to begin decreasing at the end of May,” Dr. Pontet said.

The Pfizer-BioNTech and Moderna coronavirus vaccines are 94 percent effective at preventing symptomatic Covid-19 illness, according to a new study of more than 1,800 health care workers in the United States.

The research, which the Centers for Disease Control and Prevention released on Friday, provides yet more evidence that the vaccines are working well even outside controlled clinical trials.

“This report provided the most compelling information to date that Covid-19 vaccines were performing as expected in the real world,” Dr. Rochelle Walensky, the C.D.C. director, said in a statement on Friday.

“This study, added to the many studies that preceded it, was pivotal to C.D.C. changing its recommendations for those who are fully vaccinated against Covid-19.”

The findings are based on an ongoing study of health care workers in 25 states. This interim analysis included data on 1,843 health care workers who were routinely tested for infection with the coronavirus. More than 80 percent of participants were female.

Some 623 workers tested positive between January and mid-March. Those who were fully vaccinated were 94 percent less likely to develop symptomatic coronavirus infections than their unvaccinated peers, the researchers found. The figures are consistent with the efficacy estimates from the clinical trials.

The scientists also found that a single dose of the two-shot regimen was 82 percent effective at preventing symptomatic infection. That figure is higher than has been reported in other studies and may be a result of the relative youth of the study participants, who had a median age of 37 to 38. Fewer than 2 percent were 65 or older.

C.D.C. scientists had previously found that fully vaccinated health care, frontline and essential workers were 90 percent less likely to contract the coronavirus. Those findings helped allay fears that vaccinated people might still be likely to carry the virus, even asymptomatically, and spread it to others.

The concern was one of the main rationales for asking vaccinated Americans to continue to wear masks, a recommendation that the C.D.C. lifted on Thursday.

The senior military commander who was appointed by Prime Minister Justin Trudeau of Canada last fall to oversee the distribution of Covid-19 vaccines in the country has quit that post and is now the subject of a military investigation, officials said late Friday.

In a brief, joint statement, the Department of National Defense and the Canadian Armed Forces announced Maj. Gen. Dany Fortin’s resignation but offered no details about the nature of the investigation. The department declined to comment.

Before General Fortin became Canada’s vaccine coordinator, he led military missions to help workers in long-term care homes that were overwhelmed by Covid infections. He is a former commander of the NATO mission in Iraq.

General Fortin is now the third senior leader in the Canadian Armed Forces under scrutiny. Adm. Art McDonald stepped aside as chief of the defense staff, the country’s top military job, in February after the military police opened an investigation into unspecified accusations against him. The same month, the military police also began investigating the previous chief of the defense staff, Gen. Jonathan Vance, who held the post until his retirement from the army in January.

General Vance has been accused publicly of inappropriate behavior toward female subordinates. He has denied wrongdoing.

On Dec. 29, a National Guardsman in Colorado became the first known case in the United States of a contagious new variant of the coronavirus.

The variant, called B.1.1.7, had roiled Britain, was beginning to surge in Europe and threatened to do the same in the United States. And although scientists didn’t know it yet, other mutants were also cropping up around the country. They included variants that had devastated South Africa and Brazil and that seemed to be able to sidestep the immune system, as well as others homegrown in California, Oregon and New York.

This mélange of variants could not have come at a worse time. The nation was at the start of a post-holiday surge of cases that would dwarf all previous waves. And the distribution of powerful vaccines made by Moderna and Pfizer-BioNTech was botched by chaos and miscommunication. Scientists warned that the variants — and B.1.1.7 in particular — might lead to a fourth wave, and that the already strained health care system might buckle.

That didn’t happen. B.1.1.7 did become the predominant version of the virus in the United States, now accounting for nearly three-quarters of all cases. But the surge experts had feared ended up a mere blip in most of the country. The nationwide total of daily new cases began falling in April and has now dropped more than 85 percent from the horrific highs of January.

Experts still see variants as a potential source of trouble in the months to come — particularly one that has battered Brazil and is growing rapidly in 17 U.S. states. But they are also taking stock of the past few months to better understand how the nation dodged the variant threat.

They point to a combination of factors — masks, social distancing and other restrictions, and perhaps a seasonal wane of infections — that bought crucial time for tens of millions of Americans to get vaccinated. They also credit a good dose of serendipity, as B.1.1.7, unlike some of its competitors, is powerless against the vaccines.

Once Americans return to crowded offices, schools, buses and trains, so too will their sneezes and sniffles.

Having been introduced to the idea of wearing masks to protect themselves and others, some Americans are now considering a behavior scarcely seen in the United States but long a fixture in other cultures: routinely wearing a mask when displaying symptoms of a common cold or the flu, even in a future in which Covid-19 isn’t a primary concern.

Such routine use of masks has been common for decades in other countries, primarily in East Asia, as protection against allergies or pollution, or as a common courtesy to protect nearby people.

Leading American health officials have been divided over the benefits, partly because there is no tidy scientific consensus on the effect of masks on influenza virus transmission, according to experts who have studied it.

Nancy Leung, an epidemiologist at the University of Hong Kong, said that the science exploring possible links between masking and the emission or transmission of influenza viruses was nuanced — and that the nuances were often lost on the general public.

SINGAPORE — Singapore said on Friday that it would ban dining in restaurants and gatherings of more than two people to try to stem a rise in coronavirus cases, becoming the latest Asian nation to reintroduce restrictions after keeping the illness mostly in check for months.

The new measures came after the city-state recorded 34 new cases on Thursday, a small number by global standards, but part of a rise in infections traced to vaccinated workers at Singapore Changi Airport.

The airport outbreak began with an 88-year-old member of the airport cleaning crew who was fully vaccinated but who tested positive for the virus on May 5. Co-workers who then became infected later visited an airport food court, where they transmitted the virus to other customers, officials said.

None of the cases linked to the airport outbreak are believed to have resulted in critical illness or death, according to officials.

In all, 46 cases have been traced to the airport, the largest of about 10 clusters of new infections in the country.

“Because we do not know how far the transmission has occurred into the community, we do have to take further, more stringent restrictions,” said Lawrence Wong, co-chair of Singapore’s coronavirus task force. The measures will be in effect for about one month beginning on Sunday.

According to preliminary testing, many of those infected were working in a zone of the airport that received flights from high-risk countries, including from South Asia. Several have tested positive for the B.1.617 variant first detected in India, which the World Health Organization has said might be more contagious than most versions of the coronavirus.

Singapore health officials said that of 28 airport workers who became infected, 19 were fully vaccinated with either the Pfizer or Moderna vaccines, the only two approved for use in Singapore.

“Unfortunately, this mutant virus, very virulent, broke through the layers of defense,” Transport Minister Ong Ye Kung told a virtual news conference on Friday.

Mr. Ong also said that the rise in cases “very likely” means that a long-delayed air travel bubble with Hong Kong would not begin as scheduled on May 26.

Singapore, a prosperous island hub of 5.7 million people, saw an explosion of infections among migrant workers living in dormitories, but a two-month lockdown and extensive testing and contact tracing contained the outbreak. Although Singapore has kept much of its economy open, its vaccination effort has not moved as quickly as many expected: less than one-quarter of the population has been fully inoculated.

Changi Airport, which served more than 68 million passengers in 2019, is operating at 3 percent of capacity as Singapore has paused nearly all incoming commercial traffic. Employees there work under strict controls, wearing protective gear and submitting to regular coronavirus tests.

Singapore joins Japan, Thailand and other Asian countries that have struggled to contain new outbreaks fueled in part by variants. But Paul Ananth Tambyah, president of the Asia Pacific Society of Clinical Microbiology and Infection, said that the rise in cases was not overly worrying.

“The reason for my optimism is that we now have effective vaccines, better diagnostics, proven treatments and even potential prophylactic agents,” he said. “If these are employed in a targeted approach, it is unlikely that we will end up with the same problems we had last year.”

After shortages in oxygen in New Delhi led to scores of people dying in hospitals, officials said there was now enough supply in the Indian capital to start sharing a surplus of the lifesaving gas to needier parts of the country.

For weeks, the New Delhi government appealed to Prime Minister Narendra Modi for a larger share of India’s oxygen reserves, with the battle for air ending up in the nation’s highest court.

On Thursday, just days after receiving the amount it had requested, New Delhi’s second-highest official, Manish Sisodia, said the city’s demand had fallen and its excess supply should be reallocated.

“The number of cases is coming down, hospital bed occupancy is coming down, and demand for oxygen, too, is down,” Mr. Sisodia told The New York Times.

It was an indication that the crisis in the capital might be reaching a peak.

The oxygen shortage in New Delhi began in April and has been linked to dozens of deaths, in and out of hospitals.

Health care facilities and crematories were overwhelmed, and medical professionals and residents were left scrambling for scarce resources.

Thousands of people in the city of 20 million stood in line at oxygen refilling stations, bringing cylinders into hospitals for friends and family or hoarding them at home in case the need arose.

The rise of new coronavirus infections in India has slowed. But, in pattern seen in nation after nation battered by the virus, death rates often plateau a few weeks later. And with the virus spreading in low-income rural areas, the overall crisis shows no sign of abating.

As of Wednesday, the official death toll surpassed 258,000, although experts suspect the true number to be much higher.

As the smoke from New Delhi crematories starts to clear, dozens of bodies have surfaced along the holy Ganges River in the states of Uttar Pradesh and Bihar.

Krishna Dutt Mishra, an ambulance driver in the Bihari village of Chausa, said that poor people were disposing of bodies in the river because the cost of cremations had become prohibitively expensive.

On Friday, the Indian news media showed bodies wrapped in cloth of the saffron color, considered auspicious in Hinduism, buried in shallow graves on the sandy banks of the Ganges River in the Unnao district of Uttar Pradesh.

Priyanka Gandhi, a leader of the opposition Indian National Congress party, called for a High Court investigation, saying that what was happening in Uttar Pradesh was “inhuman and criminal.”

Latino adults in the United States have the lowest rates of Covid-19 vaccination, but among the unvaccinated they are the demographic group most willing to receive the Covid shots as soon as possible, a new survey shows.

The findings suggest that their depressed vaccination rate reflects in large measure misinformation about cost and access, as well as concerns about employment and immigration issues, according to the latest edition of the Kaiser Family Foundation Covid-19 Vaccine Monitor.

Earlier polls had suggested that skepticism about the vaccine was widespread among Latinos, but the latest survey showed that hesitation is declining.

Nearly 40 percent of all the unvaccinated Latinos responding to the survey said they feared they would need to produce government-issued identification to qualify. And about a third said they were afraid that getting the shot would jeopardize either their immigration status or that of a family member.

Their responses also pointed to the importance of community-based access. Nearly half said they would be more likely to be vaccinated if the shots were available at sites where they normally go for health care.

Throughout the pandemic, few topics have touched so raw a nerve in the United States as mask wearing. Confrontations have erupted from state capitols to supermarket checkout aisles, and debates raged over whether mask mandates violate First Amendment rights.

The Centers for Disease Control and Prevention provoked a flood of reaction with its announcement on Thursday that Americans who are fully vaccinated may stop wearing masks or maintaining social distance in most indoor and outdoor settings. Here’s a sampling, edited for length and clarity, of how Times readers reacted to the news on Facebook and on our website:

“I think this is a good incentive for the hesitators. Hopefully they’ll want to participate in activities (the ones that require proof of vaccination) maskless, so perhaps this will be an incentive, as they see others in the community enjoying life more.” writes Jerry B., on Facebook.

“Very, very few people have been wearing masks for the past 6 months. Covid is a real risk — I certainly don’t want it — but our cases have dropped precipitously, even with minimal masking. This announcement is welcome — the world will not end if people stop masking,” writes Stephen from Oklahoma City.

“I see the need for this policy change, but I fear that the cheaters — those who are not vaccinated but pretend to be — will be the ruin of us all,” writes Cary in Oregon.

“I have my doubts about the incentivization bit,” writes Andrew from Colorado Springs, Colo. “I figure it will simply mean that suddenly everyone’s been fully vaccinated, true or not. That said, as a double-shotted person, I figure my chances of being taken out by an anti-vaxxer are now less than my chances of being taken out by a texting driver. I’m down with that.”

“What’s to stop anti-masker/anti-vaxxer contrarians from mingling unmasked with the vaccinated population? I have little trust in this,” writes Mary Beth in Santa Fe, N.M.

“I am fully vaccinated and caught Covid anyway. I do think it made my symptoms more mild, but you can bet your bippy I’m going to be wearing my mask when I am out of quarantine.” — writes Jaime P., on Facebook.

Boris Johnson says variant from India extra transmissible

LONDON – British Prime Minister Boris Johnson warned on Friday that the variant of the coronavirus, first discovered in India, has the potential to prevent the easing easing currently underway in the country.

The UK is now set to accelerate the second dose of vaccine for those over 50 and clinically at risk due to concerns about the Indian variant.

At a news conference on Friday, Johnson said the variant was more transmissible than other strains but warned it was not clear by how much. The English chief physician Chris Whitty speaks alongside Johnson, added that there is “confidence” that it is “more transferable” than the variants already circulating in the country.

Whitty said, “Earlier this week we said we thought it was as transferable as B.1.1.7 and possibly even more. There is now confidence … that this variation is more transferable than B.1.1.7 . “

The B.1.1.7 variant, known as the UK or Kent strain, has an unusually high number of mutations and is associated with more efficient and faster transmission of the coronavirus. British scientists first discovered this mutation in September last year, and it was the dominant strain in the United States by April

Johnson added that there is currently no evidence that the variant would dodge the vaccines that are being used across the country.

“But I have to measure myself with you, this new variant could seriously disrupt our progress,” said Johnson.

“And I have to emphasize that we will do everything we can to protect the public.”

Data on the new variant, released Thursday by Public Health England, showed the number of cases across the UK had increased from 520 last week to 1,313 this week, with most cases in North West England and some clusters concentrated in London.

The introduction of vaccines in the UK was one of the fastest in the world. Almost 70% of the adult population received at least one shot. Vaccines are available to anyone over the age of 38, but the government has said they could be made available to younger people in multi-generational households.

The next phase of England’s exit from the lockdown is slated for Monday, when the conviviality, hospitality and indoor entertainment will resume.

LONDON – UK is preparing to have vaccinations and tests carried out in areas where the new variant of Covid-19, first discovered in India, is spreading.

Vaccine Minister Nadhim Zahawi told BBC TV on Friday that the government would “bend” its vaccination program to target more doses to the hardest hit areas, while second doses could be brought forward.

In a statement late Thursday, the UK Department of Health and Welfare announced that a new surge rapid response team of 100 nurses, health advisors and environmental health officers would be deployed to Bolton, a town on the outskirts of Manchester. where variant B1.617.2 spreads quickly.

“While there is still no clear evidence that this variant has a greater impact on disease severity or evades the vaccine, the rate of growth matters and the government is considering additional measures if deemed necessary, including the best possible Using the vaccine role-out to best protect the most vulnerable in the context of the current epidemiology, “the department said in the statement.

Surge testing, along with improved genome sequencing and contact tracing, is also being rolled out to other areas across the country.

Data on the new variant, released Thursday by Public Health England, showed the number of cases across the UK rose from 520 last week to 1,313 this week, with most cases in the north-west of England and some clusters concentrated in London.

New restrictions cannot be ruled out

The introduction of vaccines in the UK was one of the fastest in the world. Almost 70% of the adult population have received at least one shot to date. Vaccines are currently available to people over the age of 38. However, the government has stated that they could be made available to younger people in multi-generational households.

The next phase of England’s exit from the lockdown is slated for Monday, when the conviviality, hospitality and indoor entertainment will resume.

However, Health and Welfare Secretary Matt Hancock said in a statement Thursday that the government is “monitoring the situation very carefully and does not hesitate to take further action if necessary”.

With the special unit in Bolton, surge tests have already been carried out in 15 areas across England, with more than 800,000 tests distributed.

“As outlined in the roadmap, we cannot rule out the possibility that economic and social restrictions will be reimposed at local or regional level if there is evidence that they are necessary to contain or suppress a variant that escapes the vaccine”, said the DHSC.

What we all know concerning the B.1.617 variant

India is grappling with a devastating second wave of coronavirus that is far more deadly than the first – and scientists say the surge could be partly due to mutating strains.

The World Health Organization has just classified the B.1.617 strain, first identified in India, as a “variant of concern” – indicating that the variant has the “highest public health impact”.

India is the second most severely affected country in the world, reporting more than 22.66 million infections and more than 246,000 deaths to date, according to data from the Indian Ministry of Health. Experts say the numbers are likely severely underreported as many never make it to the hospitals running out of beds and oxygen.

What do we know?

The earliest samples of the B.1.617 were discovered in India in October, and authorities announced in March this year that the variant had become more common in Maharashtra state.

The World Health Organization said Monday that it classifies the exposure as a “worrying variant”. It was previously referred to as a “variant of interest” which represents a lower level of alert.

Dr. Maria Van Kerkhove, technical director of Covid-19 at WHO, said there was information suggesting that B.1.617 “increased portability” and “slightly decreased neutralization”.

Variants of concern are more contagious, cause more serious illness, or reduce the effectiveness of public health measures, vaccines or drugs, according to the UN Health Agency.

“We have no evidence that our diagnostics, our therapeutics and our vaccines are not working,” she said at a press conference on Monday.

Other variants of concern are the B.1.1.7, which was first identified in the UK, and the B.1.351, which was discovered in South Africa.

According to the WHO, the threshold value for determining an interesting variant is relatively low compared to the classification of a questionable variant.

According to Gisaid, a platform that allows countries to share data about viruses, the B.1.617 strain from India has been detected in about 40 countries, including the US, UK and Singapore.

Did it trigger India’s second wave?

There are several factors that have led to a sharp increase in Indian Covid-19 cases – and mutating variants are just one of them.

The WHO said that several variants circulating in India have increased transmittability, but B.1.617 has a higher growth rate.

We’ve turned our backs on the virus, but the virus hasn’t turned our backs on us. And now we’re paying the price.

K Srinath Reddy

President of the Public Health Foundation of India

B.1.617 has three sublines, each with slightly different mutations, according to the WHO. When the cases in India experienced a “big boom”, the lineages B.1.617.1 and B.1.617.2 became more common, according to the health department.

The variant has sometimes been referred to as a “double mutant” because it contains two mutations – E484Q and L452R – that make the virus more contagious and better bypass the body’s defenses. A third mutation in the variant, the P681R, can potentially lead to “increased transmission,” the WHO said.

Virologists speaking to CNBC said the terms “double mutation” or “triple mutation” are scientifically incorrect because B.1.617 has more than a dozen mutations.

However, mass elections and religious festivals attended by millions have also been blamed for so-called super-spreader events that infected many people, according to experts.

K Srinath Reddy, President of the Public Health Foundation of India, said it was widespread that the January pandemic was “forever” over.

“It seemed that policymakers, the industry and the public were eager to get back to normal life, get the economy going again and really ignore the threat that was still there,” he told CNBCs ” Capital Connection “last week.

“As I said, we turned our back on the virus, but the virus hasn’t turned its back on us. And now we’re paying the price,” said Reddy.

Do Vaccines Work?

Ugur Sahin, CEO of BioNTech, told CNBC last month that he was “confident” that the company’s vaccine, which was jointly developed with US drug maker Pfizer, would be effective against the Indian variant.

“We had similar double mutants in our previous tests and are confident from the data we had in the past that we could see a similar way of neutralizing this virus,” he said, even though BioNTech did not have sufficient data on B. 1,617 at this point.

The WHO also said preliminary laboratory studies showed that 28 recipients of Covaxin were able to neutralize the B.1.617 variant. Covaxin is a vaccine developed by Bharat Biotech of India and the Indian State Council for Medical Research.

Former White House Director of Health Policy Dr. Kavita Patel said the current vaccines have “some effectiveness” but there have been “breakthrough infections” from variant B.1.617.

“We are very concerned. This is exactly the kind of facility for what we call ‘escape immunity’ – where the variant is so worrying and the body’s immune system cannot fight it,” she told CNBC’s Squawk Box Asia. last week.
