Don’t blame minority Brahmins for past ‘tragedies’: Pejawar seer

Bengaluru, Jun 30: Private medical colleges in Bengaluru have agreed to join hands with the Karnataka government for the treatment of COVID-19 patients.

The representatives from private medical colleges have promised the state government to provide 2000 beds immediately and another 4500 beds will be added within a week.

The development took place as Chief Minister BS Yediyurappa on Tuesday held a second round of meeting with representatives of private hospitals at Vidhana Soudha over COVID-19. 

The Chief Minister and Medical Education Minister Dr K Sudhakar held separate meetings with the representatives from private colleges administration and all the private colleges have assured to extend their support to the government decision. 

"There are 11 private and three government medical colleges in the city and we will get about 6500 beds from these for COVID treatment," Dr Sudhakar informed media after the meeting.

He further said, "These facilities including doctors and staff will be made available to the government within a week and the beds will be allocated to COVID patients through BBMP's centralised system. The insurance facility will be extended to the doctors and staff serving in these private hospitals also."

PG students in private medical colleges and other staff will be utilised in COVID Care Centres, the minister said.

"There will be some changes in the treatment protocols going forward. The decision regarding this will be taken in the meeting that will be held in the evening under the chairmanship of the CM," the minister explained.

According to him, symptomatic patients, persons aged above 60 years and those with comorbidities like diabetes, hypertension and serious kidney, liver, lungs and heart-related ailments will be admitted to hospitals. 

Other asymptomatic persons will be monitored in COVID care centres. Detailed notification with these guidelines will be released tomorrow, the minister said.

The meeting was chaired by CM BS Yediyurappa and Deputy CM Ashwatnarayana, Ministers Basavaraj Bommai, R Ashoka and senior officials were also present.

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.

Bengaluru, Jan 10: Education technology company Byju’s is learnt to have raised $200 million in a funding round from Tiger Global Management, which has valued the Bengaluru-based start-up at around $8 billion, making it the third-largest unicorn (start-up valued over $1 billion) in the country.

With this, the Byju Raveendran-founded company has seen over 50 per cent jump in its valuation in just around nine months. In March 2019, Byju’s was valued $5.4 billion, when it raised around $31 million from General Atlantic, and Chinese investment giant Tencent.

At the current valuation, Byju’s has now replaced home-grown cab-hailing major Ola as the third-largest unicorn, next only to Paytm and OYO, which are valued around $16 billion and $10 billion, respectively.

Byju’s confirmed the transaction through a press statement, though the company declined to share any specific details of the deal. Tiger Global could not be immediately reached for its comments.

“We are happy to partner with a strong investor like Tiger Global Management. They share our sense of purpose and this partnership will advance our long-term vision of creating an impact by changing the way students learn,” said Raveendran. “This partnership is both a validation of the impact created by us so far and a vote of confidence for our long-term vision.”

This is Tiger Global’s first investment in the edutech space in India after Vendantu, an online tutoring platform, where it, along with WestBridge Capital, led a $42-million round in August.

An early backer of India’s internet growth story, the New York-headquartered Tiger Global has been a prolific investor in the Indian start-up space. Its portfolio in the country ranges from consumer focused e-commerce companies that are vital for the growth of the sector, such as Flipkart, Delhivery, Grofers, Quikr and PolicyBazaar, to mention a few.

After tasting success with Flipkart, one of its earliest investments, where it had pumped in around $1 billion, the PE major is now doubling down its focus on the Indian start-up space, under its new investment head Scott Shleifer.

Shleifer, who set up international private equity practice for Tiger Global, is said to be as aggressive deal maker like his predecessor Lee Fixel, who left the investment firm in March. Since then, Tiger has also invested in a host of technology-focused companies in diverse sectors including Ninjacart, CRED, NoBroker and Facilio to mention a few.

“Byju’s has emerged as the leader in the Indian education-tech sector. They are pioneering technology shaping the future of learning for millions of school students in India,” Shleifer was quoted in the press statement issued by the edutech firm.
