Babri Masjid verdict: Jamiat Ulama-i-Hind to file review petition

Jun 3: Emphasising that airlines are clearly the safest mode of transportation, IndiGo CEO Ronojoy Dutta on Tuesday said there is no evidence yet of coronavirus infection getting transmitted among passengers onboard an aeroplane.

His comments against the backdrop of instances of some passengers, who had taken flights after resumption of domestic air services on May 25, testing positive for coronavirus.

"Those people had the virus before they got on to the aeroplane. What is noteworthy is that they have done the tracing after that. There is no evidence of transmission onboard there... that is a very encouraging sign on the safety of airline travel," he said during an earnings call.

According to him, airlines are clearly the safest mode of transportation and there is no evidence yet of contamination on an aircraft.

"You can come in contaminated but so far there is no evidence of passing it on to a fellow passenger," he noted.

Amid concerns over the coronavirus pandemic, aviation regulator DGCA has asked airlines to ensure that to the extent possible, middle seat in flights should be kept empty.

In this regard, Dutta said the airline would keep the middle seat empty wherever it can and "where we have to fill the middle seat, we will have the extra protective gown".

To a query about possible hedging of fuel prices, he said it would be a dumb idea and that airlines adjust to ups and downs in fuel prices.

"I can't overemphasise what a dumb idea it will be for an airline to hedge fuel prices. I looked at it from different angles and it is not a good idea... we looked at hedging and we talked about it at the board level and we said no," he noted.

Mumbai, May 31: Shiv Sena leader Sanjay Raut on Sunday alleged that the event held in Ahmedabad to welcome US President Donald Trump in February was responsible for the spread of coronavirus in Gujarat and later in Mumbai and Delhi, which some of his delegates had visited.

Raut also hit out at the Centre saying that the lockdown was implemented without any planning, but now the responsibility of lifting the curbs was left to the states.

The Sena MP said that despite the opposition BJP's attempts to pull down the Maharashtra Vikas Aghadi (MVA) government, there was no threat to it as its survival is the 'majboori' (compulsion) of all the three ruling allies- Sena, NCP and Congress.

"It can't be denied that the spread of coronavirus in Gujarat was because of the massive public gathering held to welcome US President Donald Trump. Some of the delegates, who accompanied Trump, also visited Mumbai, Delhi, which led to the spread of the virus," Raut said in his weekly column in Shiv Sena mouthpiece 'Saamana'.

On February 24, Trump along with Prime Minister Narendra Modi had taken part in a road-show in Ahmedabad, which was attended by thousands of people. After the road- show, the two leaders had addressed a gathering of over one lakh people at Motera cricket stadium, run by Gujarat Cricket Association (GCA).

Gujarat had reported its first coronavirus cases on March 20, when samples of a man from Rajkot and a woman from Surat tested positive for the disease.

Raut said that any move to pull down the Uddhav Thackeray-led MVA government and impose President's rule in the state citing its failure to curb the coronavirus pandemic would be suicidal.

"The state had witnessed how President's rule was imposed and lifted as per will six months ago," he said.

"If the handling of coronavirus cases is the basis of imposing President's rule, then it should be done in at least 17 states, including the BJP-ruled ones. Even the central government has failed to curb the pandemic as it had no planning to fight the virus," he said.

"The lockdown was imposed without any planning and now without any plan, the responsibility of lifting it has been left to the states. This chaos will further worsen the crisis," he said.

The Sena MP said that Congress leader Rahul Gandhi has made an excellent analysis of how the lockdown has failed.

"It is shocking that people can indulge in politics by demanding President's rule in Maharashtra for the rise in the coronavirus cases," he said.

BJP MP Narayan Rane had recently met Maharashtra Governor B S Koshyari and demanded imposition of President's rule in view of the the Shiv Sena-led state government's "failure" in tackling the coronavirus pandemic. However, the BJP had later said that it was not trying to destabilise the government.

Speaking about the stability of the government, Raut said that the survival of the MVA government was the 'majboori' (compulsion) of each of the three alliance partners.

"Even if there are internal conflicts among the ruling partners, there is no threat to the government as the allies know that its survival is the 'majboori' of each one of them," Raut said.

He said that the Devendra Fadnavis-led government, in which the BJP and Shiv Sena shared power, saw internal conflicts between the ruling allies, but it completed its full five-year term.

Slamming Fadnavis, who is now the Leader of Opposition in the Legislative Assembly, for predicting downfall of the MVA government saying it will fall on its own due to its internal bickering.

"If the Fadnavis government, which witnessed deep internal conflicts between BJP and Sena, didn't fall, how can this one collapse? The Fadnavis government survived despite the (Sena) ministers carrying their resignation letters in their pockets," Raut wrote.

Fadnavis, in an online media interaction held earlier recently, said he had no intention to destabilise the MVA government and said it would collapse on its own.

"What Fadnavis means is that all attempts (of the BJP) to create discord among the three allies and break the MLAs has failed. Now the opposition hopes that something would happen among the allies and the government would be fall apart," he said.

Raut said NCP president Sharad Pawar is the prominent leader, who laid the foundation stone of the "Thackeray sarkar", and only he can predict the future of the government.

"He continues to say the government is stable and even the Congress is not going anywhere. MVA legislators are not up for sale in horse-trading. Hence, if the opposition says that the government will fall, it is wrong," he said.

The coronavirus can stay aloft for hours in tiny droplets in stagnant air, infecting people as they inhale, mounting scientific evidence suggests.

This risk is highest in crowded indoor spaces with poor ventilation, and may help explain superspreading events reported in meatpacking plants, churches and restaurants.

It’s unclear how often the virus is spread via these tiny droplets, or aerosols, compared with larger droplets that are expelled when a sick person coughs or sneezes, or transmitted through contact with contaminated surfaces, said Linsey Marr, an aerosol expert at Virginia Tech.

Aerosols are released even when a person without symptoms exhales, talks or sings, according to Marr and more than 200 other experts, who have outlined the evidence in an open letter to the World Health Organization.

What is clear, they said, is that people should consider minimizing time indoors with people outside their families. Schools, nursing homes and businesses should consider adding powerful new air filters and ultraviolet lights that can kill airborne viruses.

What does it mean for a virus to be airborne?

For a virus to be airborne means that it can be carried through the air in a viable form. For most pathogens, this is a yes-no scenario. HIV, too delicate to survive outside the body, is not airborne. Measles is airborne, and dangerously so: It can survive in the air for up to two hours.

For the coronavirus, the definition has been more complicated. Experts agree that the virus does not travel long distances or remain viable outdoors. But evidence suggests it can traverse the length of a room and, in one set of experimental conditions, remain viable for perhaps three hours.

How are aerosols different from droplets?

Aerosols are droplets, droplets are aerosols — they do not differ except in size. Scientists sometimes refer to droplets fewer than 5 microns in diameter as aerosols. (By comparison, a red blood cell is about 5 microns in diameter; a human hair is about 50 microns wide.)

From the start of the pandemic, the WHO and other public health organizations have focused on the virus’s ability to spread through large droplets that are expelled when a symptomatic person coughs or sneezes.

These droplets are heavy, relatively speaking, and fall quickly to the floor or onto a surface that others might touch. This is why public health agencies have recommended maintaining a distance of at least 6 feet from others, and frequent hand washing.

But some experts have said for months that infected people also are releasing aerosols when they cough and sneeze. More important, they expel aerosols even when they breathe, talk or sing, especially with some exertion.

Scientists know now that people can spread the virus even in the absence of symptoms — without coughing or sneezing — and aerosols might explain that phenomenon.

Because aerosols are smaller, they contain much less virus than droplets do. But because they are lighter, they can linger in the air for hours, especially in the absence of fresh air. In a crowded indoor space, a single infected person can release enough aerosolized virus over time to infect many people, perhaps seeding a superspreader event.

For droplets to be responsible for that kind of spread, a single person would have to be within a few feet of all the other people, or to have contaminated an object that everyone else touched. All that seems unlikely to many experts: “I have to do too many mental gymnastics to explain those other routes of transmission compared to aerosol transmission, which is much simpler,” Marr said.

Can I stop worrying about physical distancing and washing my hands?

Physical distancing is still very important. The closer you are to an infected person, the more aerosols and droplets you may be exposed to. Washing your hands often is still a good idea.

What’s new is that those two things may not be enough. “We should be placing as much emphasis on masks and ventilation as we do with hand washing,” Marr said. “As far as we can tell, this is equally important, if not more important.”

Should I begin wearing a hospital-grade mask indoors? And how long is too long to stay indoors?

Health care workers may all need to wear N95 masks, which filter out most aerosols. At the moment, they are advised to do so only when engaged in certain medical procedures that are thought to produce aerosols.

For the rest of us, cloth face masks will still greatly reduce risk, as long as most people wear them. At home, when you’re with your own family or with roommates you know to be careful, masks are still not necessary. But it is a good idea to wear them in other indoor spaces, experts said.

As for how long is safe, that is frustratingly tough to answer. A lot depends on whether the room is too crowded to allow for a safe distance from others and whether there is fresh air circulating through the room.

What does airborne transmission mean for reopening schools and colleges?

This is a matter of intense debate. Many schools are poorly ventilated and are too poorly funded to invest in new filtration systems. “There is a huge vulnerability to infection transmission via aerosols in schools,” said Don Milton, an aerosol expert at the University of Maryland.

Most children younger than 12 seem to have only mild symptoms, if any, so elementary schools may get by. “So far, we don’t have evidence that elementary schools will be a problem, but the upper grades, I think, would be more likely to be a problem,” Milton said.

College dorms and classrooms are also cause for concern.

Milton said the government should think of long-term solutions for these problems. Having public schools closed “clogs up the whole economy, and it’s a major vulnerability,” he said.

“Until we understand how this is part of our national defense, and fund it appropriately, we’re going to remain extremely vulnerable to these kinds of biological threats.”

What are some things I can do to minimize the risks?

Do as much as you can outdoors. Despite the many photos of people at beaches, even a somewhat crowded beach, especially on a breezy day, is likely to be safer than a pub or an indoor restaurant with recycled air.

But even outdoors, wear a mask if you are likely to be close to others for an extended period.

When indoors, one simple thing people can do is to “open their windows and doors whenever possible,” Marr said. You can also upgrade the filters in your home air-conditioning systems, or adjust the settings to use more outdoor air rather than recirculated air.

Public buildings and businesses may want to invest in air purifiers and ultraviolet lights that can kill the virus. Despite their reputation, elevators may not be a big risk, Milton said, compared with public bathrooms or offices with stagnant air where you may spend a long time.

If none of those things are possible, try to minimize the time you spend in an indoor space, especially without a mask. The longer you spend inside, the greater the dose of virus you might inhale.
