‘Army killed this 12-year-old girl when she was giving water to an injured relative’

New Delhi, Feb 27: Congress leader Priyanka Gandhi Vadra on Thursday attacked the government over the transfer of Delhi High Court Judge S Muralidhar, saying the Centre's attempts to "muzzle" justice and "break people's faith in an upright judiciary are deplorable".

Delhi HC Judge S Muralidhar was transferred to the Punjab and Haryana High Court, days after the Supreme Court collegium made the recommendation.

"The midnight transfer of Justice Muralidhar isn't shocking given the current dispensation, but it is certainly sad & shameful," Priyanka Gandhi tweeted. "Millions of Indians have faith in a resilient & upright judiciary, the government’s attempts to muzzle justice & break their faith are deplorable," she said.

The judge was hearing the Delhi violence case and the late evening notification came on the day when a bench headed by him expressed "anguish" over the Delhi Police's failure to register FIRs against alleged hate speeches by three BJP leaders.

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.

New Delhi, Mar 6: As panicky depositors rushed to withdraw money from Yes Bank whose control was seized by the RBI in a dramatic late-night move, Finance Minister Nirmala Sitharaman on Friday assured depositors that their money is safe and said the central bank was working for an early resolution of the crisis.

The Reserve Bank of India (RBI) on Thursday evening capped withdrawals at Rs 50,000 for the next one month and imposed strict limits on operations at the country's fourth-largest private lender that faced "regular outflow of liquidity" after an effort to raise new capital failed.

"I am in continuous interaction with the RBI. The RBI is fully seized of the matter and has assured they will give a quick resolution," Sitharaman said here.

She said no depositor will lose his or her money and insisted that the immediate priority is to ensure Yes Bank customers are able to withdraw money within the stipulated cap.

"I want to assure every depositor that their money shall be safe. Their monies are safe," she said. "I am constantly in contact with the RBI and the steps that are taken are taken in the interest of depositors, banks and economy. We are fully seized of the development."

She was talking to reporters after meeting State Bank of India (SBI) Chairman Rajnish Kumar. On Thursday, the SBI board gave its "in-principle" approval to exploring investment opportunities in Yes Bank.

"So I repeat, the depositors can be assured that their money is safe," she said.

Soon after the RBI takeover, depositors thronged Yes Bank ATMs to withdraw money and police had to be deployed in some places to control the crowds.

Yes Bank has 1,000 branches across the country.

Refusing to elaborate on her meeting with the SBI chairman, the minister said that "was on a completely different matter".

"RBI governor has given me assurance that there will be an appropriate resolution soon. No depositor will lose (money)," she said. "Reserve Bank has taken cognizance of the problem."

The central bank, she said, has gone through the "process over and over again to find out an amicable solution".

"And that has been over the last couple of months. So it is not as if they have come in suddenly now. We have been monitoring the situation," she said adding the RBI has appointed an administrator who previously was with the SBI.

"Both the RBI and the government are looking at this with all the details before them, not just today. I have personally monitored the situation over the last couple of months with the RBI. Therefore we have taken a course which will be in everybody's interest," she added.

Yes Bank had been seeking new capital since last year to bolster its ratios and quell questions about its stability due to its exposure to the non-banking finance industry entangled in a prolonged crunch in the local credit market.

The SBI chairman said the resolution to the Yes Bank crisis will come "very shortly".

"This is not a sectoral problem. It is a bank-specific problem," he said. "The RBI will take all steps to ensure financial stability."

On SBI picking up a stake in Yes Bank, he said the lender already has an in-principle approval for doing so.

"If SBI has to pick up a stake in Yes Bank, we have an in-principle approval for that," he said.

Commenting on the crisis at Yes Bank, Alka Anbarasu, Vice President – Senior Credit Officer, Financial Institutions, Moody's Investors Service, said: "RBI's moratorium on Yes Bank is credit negative as it affects timely repayment of bank depositors and creditors."

"While Moody's expects Indian authorities will take steps to prevent the weakness in the bank's viability from significantly impacting its depositors and senior creditors, the lack of a coordinated and timely action highlights continued uncertainty around bank resolutions in India," she said.
