In Delhi, the mercury soared to 47.6 degrees Celsius in Palam area and most places recorded their maximum temperatures six notches above normal. The Safdarjung Observatory, which provides representative figures for the city, recorded a maximum of 46 degrees Celsius.

The last time when the mercury at the Safdarjung weather station touched the 46-degrees-Celsius mark was on May 19, 2002.

The IMD said the weather stations at Lodhi Road and Aya Nagar recorded their respective maximum at 45.4 degrees and 46.8 degrees Celsius.

In its earlier forecast, the IMD has said that dust storm and thunderstorm with winds gusting up to 60 kilometres per hour is likely over the National Capital Region on Friday and Saturday.

On the other hand, severe heatwave conditions prevailed in several parts of Rajasthan on Tuesday, with the mercury touching 50 degrees Celsius in Churu district.

The IMD said this is the second-highest maximum temperature recorded in Churu district in the month of May in the last 10 years.

Other areas such as Bikaner, Gangangar, Kota and Jaipur recorded maximum temperatures of 47.4 degrees Celsius, 47 degrees Celsius, 46.5 degrees Celsius and 45 degrees Celsius, respectively.

In the adjoining areas of Chandigarh, the severe heatwave condition continued in Haryana, Punjab with Hisar being the hottest place in the region at 48 degrees Celsius.

Guwahati, Feb 13: Hours after Assam's updated citizenship data disappeared from the website 'nrcassam.nic.in', an FIR was filed against a former NRC official for allegedly failing to submit the password to the sensitive document before quitting her job.

Talking to news agency on Thursday, NRC state coordinator Hitesh Dev Sarma said the complaint against former NRC project officer was filed under Official Secrets Act in Paltan Bazar police station here, as she "did not provide the password to the document, despite written reminders".

"She failed to surrender the password even after tendering her resignation on November 11 last year. She was a contractual employee and no longer authorised to hold the password, after quitting her job. An FIR has been filed against the former NRC project officer on Wednesday for violating the Official Secrets Act," he said.

Sarma also stated that the NRC office had written to her on several occasions for submitting the password, but did not get any response.

"We knew (she had resigned) and, therefore, sent several letters to her for handing over the password. But as she did not respond all these months, we filed a complaint against her yesterday for violating the Official Secrets Act.

"We must know if she has tampered with the sensitive information, after resigning," he added. The NRC state coordinator, however, refuted allegations of "malafide intent" involved in the matter.

"...this (cloud service provided by IT major Wipro) was not renewed by the earlier coordinator. So, the data went offline from December 15 last year. I assumed charge only on December 24," Sarma, who had gone on leave for a weeks after being appointed as the NRC state coordinator, clarified.

He also said that the state coordination committee had discussed the issue in its meeting on January 30 and wrote to Wipro during the first week of February.

"Once Wipro makes the data live, it will be available to the public. We hope that people will be able to access it in the next 2-3 days," Sarma claimed.

Reacting to the development, Wipro had said: "The IT Services Contract was not renewed by the authorities upon its expiry in October, 2019. However, as a gesture of goodwill, the company continued to pay the hosting service fee until January-end, 2020."

In another FIR filed with state criminal investigation department on Wednesday, NGO Assam Public Works (APW) alleged that former NRC Assam coordinator Prateek Hajela tampered with the final NRC list - published on August 31, 2019.

APW member Rajib Deka, in his complaint, accused Hajela of disobeying orders and directions of the Supreme Court, forgery of public register and committed offences under cyber laws for altering or changing public records by misusing his powers and position.

The NGO also said that after publication of the final list, several social networks and sections of the media had reported anomalies, insisting that many 'doubtful' persons were able to insert their names in the final list.

The Centre on Wednesday asserted that NRC data in Assam was safe even though some technical issues have been detected, which would be resolved soon.

Senior journalist-cum-RTI activist Saket Gokhale had sent an application to the NIC, the IT wing of the government, seeking a copy of the contract with Wipro.

"The Assam NRC data suddenly vanishing from the website (& the lack of data security) is incredibly shady. I've filed an RTI with the NIC specifically asking about details of the contract with Wipro, name of the cloud service provider, & all contracts signed for hosting this," he tweeted, while attaching a copy of the RTI application.

Leader of the Opposition in Assam Assembly and Congress leader Debabrata Saikia has also written to the Registrar General of India, requesting him to look into the fiasco urgently.

"It is a mystery as to why the online data should vanish all of a sudden, especially as the process to file appeals was yet to begin, all because of the go-slow attitude adopted by the NRC Authority. There is, therefore, ample scope to suspect that disappearance of online data is a malafide act," he had insisted.

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.
