Ambareesh wants JD(S) govt in Karnataka: H D Kumaraswamy

San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.

Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.

Of those who reported a loss of smell and taste, the loss was typically profound, not mild.

"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.

"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.

For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.

Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.

Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.

"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.

"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.

Sensory return typically matched the timing of disease recovery.

In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.

"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.

New Delhi, May 8: After deadly styrene gas leak in Visakhapatnam, Union Chemicals and Fertilisers Minister D V Sadananda Gowda urged all public and private chemical makers to exercise caution and care while reopening their plants.

Union Environment Ministry and State Pollution Control Boards have also issued separate directives to all companies to take extreme precaution while restarting their units that remained suspended due to the lockdown imposed to contain the spread of COVID-19 in the country, he said.

There was a gas leak from LG Polymers plant at Visakhapatnam in the early hours on Thursday, causing 10 deaths and hundreds of people getting hospitalised.

"LG Polymers does not come under direct control of our ministry. However, we have asked all public and private chemicals manufacturers to exercise caution and care while reopening their plants," Gowda told PTI.

The minister said his officers are coordinating with the Andhra Pradesh government.

He further said LG Polymers, a multinational chemical company, had kept its unit ready for reopening after one and half month of lockdown. The unit started leaking at around 3.40 am on Thursday due to pressure.

"The toxic gas leak has affected both people and animals. Around 850 people have been hospitalised," Gowda said, adding that measures have been taken to control the situation at the plant site and final updates are awaited.

At present, Indian chemicals market size is about USD 163 billion, which is only three per cent of the global chemical industry of USD 5 trillion, as per the official data.

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.
