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.

Brazil fears third Covid wave as Bolsonaro faces parliamentary inquiry

Brazilian President Jair Bolsonaro is undergoing a congressional investigation into the mismanagement of the pandemic.

Health experts fear the Brazilian Covid-19 disaster could get worse in the coming months, while a parliamentary investigation into the government’s response to the pandemic is likely to increase political pressure on President Jair Bolsonaro.

South America’s largest country, previously known for its leadership skills in health crises, has grown into an international pariah amid the coronavirus pandemic. Brazil has had the highest number of coronavirus-related deaths in the world outside the US, has lagged behind on vaccinations and still lacks an effective and coordinated public health response to the outbreak.

An official investigation, approved by the Brazilian Supreme Court, opened late last month to look into the government’s handling of the pandemic, which killed more than 430,000 people. The investigation could pave the way for Bolsonaro’s impeachment, though analysts say political opponents of the right-wing leader may prefer to contest the president in the October 2022 election.

Bolsonaro has reportedly said he was “not concerned” about the investigation. A Brazilian government spokesman did not respond to a request for comment when contacted by CNBC.

Bolsonaro has repeatedly spoken out against public health measures, which have become a political battleground in Brazil, and continues to oppose any lockdown measures to contain the spread of the virus.

“The current unrestrained epidemic will not be overcome without a dramatic change in direction,” said Dr. Antonio Flores, Infectious Disease Specialist and Covid Medical Advisor at the Medecins Sans Frontieres aid group in Brazil.

He said that if life goes on normally, “with such a high daily incidence, all you can expect is a new wave of cases, an additional thousands of deaths and more pressure on the already stretched health system.”

His comments echo warnings from other health experts that Brazil could soon experience a third wave of Covid infections in the coming weeks. It is feared that the country’s weak vaccination efforts will not be enough to prevent a new surge in the winter months of June through September, when indoor gatherings and activities are particularly risky.

Flores told CNBC that all available public health measures should be stepped up “as soon as possible” and that the country’s vaccination campaign needs to be accelerated. He added the need to put in place an effective testing and traceability system, as well as coherent guidelines on public health restrictions.

“A crucial element in next year’s elections”

By May 12, according to statistics from Our World in Data, around 15% of Brazil’s 211 million inhabitants had received at least one dose of a Covid vaccine. Chile has now vaccinated nearly 46% of its population with at least one dose of a Covid vaccine, reflecting one of the highest vaccination rates in the world.

Brazil’s lower vaccination rate means millions of people across the country and beyond its borders are at risk from more than 90 variants of the coronavirus currently circulating in the country – in addition to any new mutations that may emerge.

Brazil’s Covid vaccination campaign is in stark contrast to its response to the H1N1 swine flu pandemic in 2009, when 92 million people were vaccinated against the virus in just three months. The main difference this time around, analysts say, is Bolsonaro’s refusal to take a science-led approach to addressing the health crisis.

This is a very dangerous government, but since it was democratically elected, very little can be done at the moment to push back.

President of the Igarape Institute

The Pan American Health Organization announced on Wednesday that nearly 40% of all global Covid-related deaths reported in the past week have occurred in the Americas. Almost 80% of the intensive care units in the region are currently staffed with patients. PAHO director Carissa Etienne warned it was clear the broadcast “is far from being controlled,” even as the US and Brazil report reductions in some cases, Reuters reported.

Brazil recorded more than 74,000 cases of the coronavirus on Thursday, after peaking at over 100,000 daily infections in April. In terms of infection numbers, it remains the third worst Covid-affected country in the world after the US and India.

“I think while the situation in India has gotten significantly worse lately, the numbers in Brazil have risen to a very, very high level. The country has actually been in a collapse for months,” said Oliver Stuenkel, Associate Professor of International relations at the Getulio Vargas Foundation in Sao Paulo, said CNBC by phone.

“What is really so fascinating is that (former US President Donald) Trump and to some extent (Indian Prime Minister Narendra) Modi are paying a political price. Bolsonaro has been able to and has not retained fairly high political support by a combination of factors done. ” however, had to pay for it because its strategy of avoiding responsibility has so far been remarkably successful, “he added.

Analysts said the government’s investigation into treatment for the pandemic will typically take around three months, but the process can take much longer.

Stuenkel said he expected the investigation to take about six months since “the real goal is to hammer home the news on the evening news that Bolsonaro was to blame”.

“Essentially, I think the investigation will be vital because if the investigation cannot change public opinion at this point, after 400,000 people have died and basically the health system has finally collapsed, basically nothing can .. . For me the crucial element is next year’s election, “he added.

What happens next?

Earlier this week, former Brazilian Health Minister Luiz Henrique Mandetta, who was fired over a year ago after resisting Bolsonaro’s push to use the malaria drug chloroquine as a covid treatment, testified ahead of a parliamentary inquiry.

Mandetta said Bolsonaro was fully aware that the treatment had no scientific basis. Former US President Donald Trump had also pushed for the use of the related drug hydroxychloroquine amid the pandemic, despite a lack of scientific evidence.

“Unfortunately, this is a very dangerous government, but since it was democratically elected, very little can be done right now to push back,” said Ilona Szabo, president of the Igarape Institute, a think tank based in Rio de Janeiro.

Szabo said that while she did not believe the investigation would have “immediate” political implications, “it is important that what happens today has ramifications for the future.”

“It is proven that they are responsible and that most of the deaths were preventable,” said Szabo.

CDC says 28 blood clot instances, three deaths could also be linked to J&J Covid vaccine

The Johnson & Johnson Janssen vaccine

CDC scientists say their investigation into a rare blood clotting problem related to the Johnson & Johnson Covid-19 vaccine identified 28 people who may have developed life-threatening blockages – three of whom have died.

The Food and Drug Administration and Centers for Disease Control and Prevention urged states on April 13 to temporarily cease use of J & J’s vaccine “out of caution” while examining six women ages 18 to 48 who developed cerebral venous sinus thrombosis, or CVST combined with low platelets within about two weeks of receiving the shot.

They recommended resuming use of the shot 10 days later after the CDC found the benefits of the vaccinations outweighed their risks.

CVST is a form of thrombosis with thrombocytopenia, or TTS, which are blood clots with a low platelet count that make patients at risk of stroke. Platelets actually help the blood to clot.

CDC official Dr. Tom Shimabukuro said Wednesday that four of the 28 people with TTS were hospitalized on May 7, one of whom was in intensive care, and two were being discharged to a post-acute care facility. The remaining 19 patients have all been discharged, he said during a presentation to the CDC Advisory Committee on Immunization Practices. The panel voted earlier in the day to recommend the Pfizer BioNTech vaccine for 12 to 15 year olds.

The mean age of the patients with TTS was 40 years and ranged from 18 to 59 years. Women aged 30 to 39 were the greatest risk group. All patients received the J&J shot before the April 13 break. Of the 28 TTS cases, 19 involved the brain, with 10 of those patients suffering from cerebral haemorrhage, Shimabukuro said.

The other clots formed in the lower extremities, pulmonary arteries, or other areas of the body.

A Phishing Check Promised Employees a Covid Bonus. Now They Need an Apology.

A report released this week by the UK’s National Cyber ​​Security Center showed a 15-fold increase in the number of scams being removed from the internet and said the agency had taken more fraudulent websites offline than in the past year together for the past three years.

Let us help you protect your digital life

In the first quarter of this year, government statistics showed that nearly 40 percent of businesses in the UK reported digital security breaches or attacks, with the average cost for medium to large businesses around £ 13,400 or $ 18,800. The cost of a major breach can be far more daunting: a study last year by the Ponemon Institute for IBM Security that polled 524 organizations in 17 countries found that data breaches averaged an organization $ 3.86 million in 2020 costs.

Phishing has also been used by scammers trying to get grandparents out of their savings, intelligence agencies to get information and diplomatic levers, and IT departments to see if employees are paying attention.

“A well-designed phishing email gets 100 percent clicks,” said Steven J. Murdoch, professor of security engineering at University College London, adding that all companies are vulnerable to phishing.

However, testing employees with fake emails about bonuses is “a trap,” he said, adding that it could jeopardize the company-employee relationship, which is vital to security. For example, some attacks come from disgruntled employees, he said. “People responsible for fire safety do not set the building on fire,” he said of the tests.

Instead of preventing employees from clicking a link, more effective strategies could include blocking phishing emails, installing software to protect against ransomware, and addressing the use of passwords.

The alienation of employees also meant they were less likely to report suspicious activity to their corporate departments. It’s a crucial way to keep attacks from getting worse, said Jessica Barker, co-founder of Cygenta, a cybersecurity company.

Abbott CEO says it has a workforce of ‘virus hunters’ on new Covid variants

An Abbott Labs employee receives the BinaxNOW Covid-19 antigen rapid test at her workplace.

Abbott Labs

Abbott Labs has a team of “virus hunters” working with health officials around the world to monitor Covid-19 variants as some mutant strains show the ability to evade detection, CEO Robert Ford said during an interview, which aired Tuesday as part of CNBC’s Healthy Returns the event.

“They’re always on the lookout for new viruses, and in this case we’ve put a team together to monitor all possible mutations,” he said of the coalition pandemic defense. “It can’t be just a US thing, you have to work with all the countries, all the universities, all the different collection points, then I think this is the way to go.”

The Food and Drug Administration warned clinical staff in January that new variants could lead to false negative Covid-19 test results. The agency identified three tests, none of which were performed by Abbott, and which may be less accurate because the part of the SARS-CoV-2 gene sequence that the tests were looking for was mutated in some variants.

Ford also made it clear that with the rate at which Covid-19 is mutating, there is no time to be wasted. Scientists need to “chase these mutations,” he said.

In the meantime, scientists are developing a new generation of tests that will look for parts of the virus that are less likely to mutate and give false negative results.

Antigen tests, such as those used in Abbott’s popular Binaxnow Covid-19 tests, target proteins in the virus that are less likely to mutate over time.

Covid Desperation Is Spreading Throughout India

NEW DELHI – Dozens of bodies washed up on the banks of the Ganges this week, most likely the remains of people who have died of Covid-19.

States in southern India have threatened to stop sharing medical oxygen and they have great protection from holding onto what they have as their hospitals soar with the sick and infections.

And at a hospital in Andhra Pradesh, a rural state in southeastern India, angry relatives raged in the intensive care unit after suddenly running out of life-saving oxygen – the latest example of the same tragedy repeated when patients died while gasping for breath.

The desperation that has plagued New Delhi, India’s capital, in recent weeks is now spreading across the country, hitting states and rural areas with far fewer resources. Positivity rates are rising in these states, and public health experts say the rising numbers are most likely well below the real picture in places where diseases and deaths caused by Covid-19 are harder to track.

It seems that the crisis is entering a new phase. Cases in New Delhi and Mumbai could flatten. But many other places are being overwhelmed by runaway outbreaks. The World Health Organization is now saying that a new variant of the virus discovered in India, B.1.167, may be particularly transmissible, which only increases the feeling of alarm.

Every day the Indian media delivers a huge dose of turmoil and sadness. On Tuesday, televised images of distraught relatives beating angrily on the chests of loved ones who died after the oxygen was depleted, and headlines such as “Bodies of Suspicious Covid-19 Victims Found Floating” and “As Deaths Go Up.” 10 Fold, Worrying “Characters from Smaller States. “

This has always been the burning question: if New Delhi, home to the country’s elite and numerous hospitals, couldn’t handle the surge in coronavirus cases due to a devastating new wave, what would happen in poorer rural areas?

The answer is coming in now.

On Monday evening, Sri Venkateswara Ramnarain Ruia’s government general hospital in Andhra Pradesh ran out of medical oxygen. More than 60 patients were in critical condition and had oxygen masks on their faces. Doctors desperately called to suppliers for help.

But the oxygen ran out and killed 11 people. Distraught family members got so angry, hospital officials said, that they stormed into the intensive care unit, turned tables and smashed equipment. Television images showed women clutching their heads, overwhelmed with grief. Doctors and nurses fled until police officers arrived.

India is suffering from a worrying shortage of medical oxygen and at least 20 other hospitals have run out. Almost 200 patients have died from it, according to an Indian news site that has been following the string of fatal incidents.

At the same time, the national vaccination campaign stutters. The roughly two million doses administered daily for the past few days are lower than the highs a few weeks ago, when the country gave more than three million doses on a few days. Lots of people can’t find dates to get the shot. Some vaccination centers are completely exhausted, officials say.

All of this leads to the harshest criticism that Narendra Modi, India’s powerful prime minister, has faced since he took office seven years ago. He has been widely accused of declaring premature victory over coronavirus and encouraging his country to drop his guard.

Modi’s Bharatiya Janata party remains by far India’s most powerful political organization. But the solid wall that the party has maintained during this crisis may show some cracks.

Several party setters in Uttar Pradesh, India’s largest state and one controlled by Mr. Modi’s party, have started complaining about the state government’s response.

“There is no break in the corona and we helplessly watch our own people die,” wrote Lokendra Pratap Singh, a lawmaker for Mr. Modi’s party, in a letter that quickly went viral.

Nationwide, the picture remains bleak, although the situation in India’s two largest cities appears to be improving.

The capital New Delhi reported 12,481 new infections on Tuesday, less than half of the infections reported on April 30. The positivity rate among those tested for the coronavirus has steadily declined in the city, from a worrying high to 19 percent from 36 percent a few weeks ago.

Something similar happened in Mumbai, India’s commercial capital, and people are now wondering if the worst is over. The positivity rate in Mumbai has dropped from around 25 percent to around 7 percent.

Hospitals in Delhi that closed their doors last month due to a shortage of life-saving supplies and killed people on the streets are again accepting patients. But the situation for those who get sick is still extremely precarious. On Tuesday afternoon, a cell phone app for New Delhi, a metropolis of 20 million people, showed only 62 free beds in the intensive care unit for Covid-19 patients across the city.

Understand India’s Covid Crisis

Some of the worst-hit states are now in the south, particularly Karnataka, home of India’s Bangalore technology center. An oxygen express train, part of the Modi government’s effort to carry liquid oxygen to Covid-19 hotspots, chugged into Bangalore Tuesday morning.

But the state needs more.

By this week, the southern states had agreed to share the oxygen supply. Now some are arguing to end the collaboration. Neighboring Kerala says it cannot send oxygen because it needs all of its supplies for its own growing needs. Tamil Nadu, also in the south, says the same thing and cannot provide for its poorer neighbor Andhra Pradesh, where the eleven people died on Monday evening at the oxygen limit.

“I can hardly imagine what is going on in rural India,” said Rijo M. John, a health economist in Kerala, where the positivity rate rose from around 8 percent in early April to nearly 27 percent on Tuesday.

Mr John said that rural areas do not have many Covid tests and that many people “may die from not receiving treatment at all”.

One particularly troubling omen came in a river village in Bihar, a rural state in northern India. In the village of Chausa, residents felt deeply uncomfortable after discovering dozens of bodies mysteriously washed up on the banks of the Ganges.

Nobody knows who these people were or how their bodies got there. The villagers found her on Monday evening. Stunned spectators crowded around the remains, many in brightly colored clothes, floating in the shallow water. Images of the bloated bodies have made the rounds in the Indian media and unsettled countless people.

Officials said about 30 bodies were found. Witnesses put the number at over 100.

Every now and then, the villagers said, they see a single corpse floating in the river. It is part of a custom whereby some families send the corpses of loved ones into the Ganges, the holiest river in Hinduism weighed down with stones. But Chausa officials and residents suspect the unprecedented number of bodies they found this week belonged to victims of Covid-19.

“I’ve never seen so many bodies before,” said Arun Kumar Srivastava, a government doctor in Chausa.

When Covid-19 devastated this area, Dr. Srivastava, he saw more and more people carrying corpses, sometimes on their shoulders. “Absolutely,” he said. “More deaths happen.”

Krishna Dutt Mishra, an ambulance driver in Chausa, said many poor people dumped bodies in the river because cremation prices rose from rupees 2,000, about $ 27, to rupees 15,000 since the second wave of Covid. about $ 200, which is an insurmountable amount for most families.

This has become a problem across India. Covid-19 deaths have overwhelmed the grounds for cremation, and some unscrupulous cremation workers are now charging five or even ten times the normal price of the final rites.

“I drove the entire distance from Buxar to Chausa,” said Mishra, referring to another town a little further east. “I’ve never seen a few bodies, let alone so many, lined up along this stretch of the river.”

Hari Kumar and Shalini Venugopal Bhagat contributed to the coverage.

India Covid disaster: Mucormycosis fungal an infection

As India grapples with a deadly second wave of coronavirus, authorities have warned of a rare fungal infection that can be maimed or even fatal if not cared for.

Multiple media reports say doctors in the country are reporting cases of mucormycosis, informally known as “black fungus,” in the recovery or recovery of Covid-19 patients in states like Maharashtra and Gujarat, as well as Delhi.

What is it?

Mucormycosis is a “serious but rare fungal infection caused by a group of molds called mucormycetes,” according to the US Centers for Disease Control and Prevention. It most commonly affects the sinuses or lungs after inhaling fungal spores from the air, but it can also appear after an injury to the skin or, in some cases, affect the brain, according to the CDC.

The infection is more common in people who have underlying health problems or are taking medications that affect their body’s ability to fight germs. Researchers studying previous murcormyscosis infections in India found that diabetes was the most common underlying disease, occurring in 54% to 76% of cases.

While the infection is treatable, the CDC estimates a death rate of around 50%, but this varies depending on the underlying conditions, the type of fungus, and the area of ​​the body affected.

However, the Indian State Council for Medical Research (ICMR) said that patients who have been in intensive care units for long periods of time or are immunocompromised due to steroids may also be at risk.

Many severe Covid-19 patients in India are treated with corticosteroids such as dexamethasone, an anti-inflammatory drug that also decreases the immune system’s ability to fight infections and other diseases to relieve symptoms and make them more susceptible.

A government official reportedly said last week that there is “no major outbreak” of the fungal infection in India.

What are the symptoms?

The ICMR issued a notice over the weekend urging doctors and patients to look out for early symptoms.

These include nasal congestion and discharge, unilateral facial pain, numbness or swelling, toothache and loosened teeth, blurred or double vision, redness around the eyes, fever, difficulty breathing and chest pain.

Treatment options include antifungal therapy, Reducing or stopping steroids and other drugs that suppress the immune system, while more severe cases, according to the ICMR, may require surgery to remove all necrotic tissues from the body.

If left untreated for too long, permanent damage such as vision loss and death can result.

Mucormycosis was already present in India before the Covid-19 pandemic began last year. Official data are scarce due to the lack of population-based studies, but some researchers estimate that the prevalence of mucormycosis in the country is about 70 times higher than in the rest of the world.

WHO classifies triple-mutant Covid variant from India as world well being danger

World Health Organization (WHO) Director General Tedros Adhanom Ghebreyesus will attend a press conference at WHO headquarters on July 3, 2020, organized by the United Nations’ Association of Geneva Correspondents (ACANU) in the context of the COVID-19 outbreak caused by the novel coronavirus was organized in Geneva.

A World Health Organization official said Monday that the highly contagious triple mutant variant of Covid widespread in India is being classified as a “worrying variant,” suggesting it has become a global health threat.

Maria Van Kerkhove, WHO technical lead for Covid-19, said the agency would provide more details in its weekly status report on pandemic Tuesday, but added that the variant known as B.1.617 was found in preliminary studies to do more Spread more easily than the original virus and there is some evidence that it can evade vaccines.

“And as such, we classify this as a variant of the concern on a global scale,” she said during a press conference. “Although some preliminary studies show increased transferability, we need a lot more information about this virus variant in that line in all sublines. Therefore, we need to do more sequencing and targeted sequencing.”

The WHO announced last week that it is closely tracking at least 10 coronavirus variants worldwide, including the B.1.617. The variant was previously called the “variant of interest” because more study was needed to fully understand its meaning, Van Kerkhove said.

“For everyone in the home, this means that any circulating SARS-CoV-2 virus can infect and spread you, and anything to do with that is worrying,” she said on Monday. “So, all of us at home, no matter where we live, no matter what virus is circulating, we need to make sure we take all necessary measures to keep us from getting sick.”

A variant can be classified as “worrying” according to the WHO if it is found to be more contagious, more deadly and more resistant to current vaccines and treatments.

The international organization has already identified three other variants with the classification: B.1.1.7, which was first discovered in Great Britain and is currently the most widespread variant in the USA; B. 1.351, detected for the first time in South Africa, and the P.1 variant, detected for the first time in Brazil.

B.1.617 has three sub-lines, said Van Kerkhove, which are described in Tuesday’s management report.

Some believe the variant is behind the recent wave of infections in India.

The country averages 3,879 Covid deaths per day, according to data from Johns Hopkins University, although media reports suggest the official number is underestimated. Over the past seven days, an average of 391,000 new cases per day have been reported – an increase of about 4% from a week, data from Johns Hopkins University shows.

The variant has since expanded to other countries, including the United States.

Singapore’s overseas minister says Covid will not go away fully

Crowds thronged Singapore’s Orchard Road shopping belt to prepare for the festive season on December 12, 2020 amid the Covid-19 pandemic.

SINGAPORE – Covid-19 is “permanent” and subsequent waves of infection will occur normally in the coming years, Singapore Foreign Minister Vivian Balakrishnan told CNBC.

“Covid-19 is endemic to humanity, which means it will never go away completely,” Balakrishnan told CNBC’s Squawk Box Asia on Monday.

“And the reason it won’t go away completely is because it’s spread around the world, has sufficient critical mass, the rate of mutations and new variants continues, and the level of human immunity increases and decreases as well,” said he said.

The minister, who was a doctor before entering politics, also warned that now could be a “more dangerous time” for vaccinated people who might be complacent, as well as those who are not vaccinated and have no protection against Covid.

Balakrishnan said vaccination is critical and that people who have received Covid shots develop fewer symptoms and have fewer serious illnesses, even when infected. However, vaccination alone is not the panacea for an “exponential explosion” in Covid cases.

That means measures such as social distancing and border restrictions may have to “come and go” in response to waves of Covid infection over the next two years, the minister said.

Singapore tightened social restrictions over the weekend after the number of cases increased in the community. Cumulatively, the country confirmed more than 61,300 cases and 31 deaths on Sunday, data from the Ministry of Health showed.

Balakrishnan said around 20% of Singapore’s population has been vaccinated, but the government has no defined threshold for achieving “herd immunity”. He explained that with the emergence of new variants of Covid, the level of protection required in a community will change so that the disease no longer spreads quickly.

It is likely that immunity to vaccinations will also decrease over time. So the point is, you can’t wait to say that you have reached the magical figure and suddenly you are immune and the mask has taken off and there are no restrictions.

“As new variants evolve and these new variants actually appear to be more contagious than the original strain, the level of herd immunity will mathematically change,” Balakrishnan said.

“It’s likely that immunity to vaccinations will also wear off over time. So the point is, you can’t expect to have reached the magical figure and suddenly be immune and mask off and not have any restrictions,” said he added.

Singapore-Hong Kong travel bubble

Singapore is a Southeast Asian city-state with no domestic air travel market. The country has reached an agreement with Hong Kong – a city that also has no domestic flight market – to create a travel bubble that will allow travelers to skip the quarantine.

When CNBC asked if the program should start on May 26th, Balakrishnan said, “As of now, the plan is yes, but we have to see how the situation develops over the next few days.”

The launch of the air travel bubble – originally scheduled for November 2020 – has been postponed several times after a surge in coronavirus cases in Hong Kong.

The two cities announced last month that the program will begin with one flight per day to each city with up to 200 travelers per flight.
