Gangster Vikas Dubey killed in police 'encounter'

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

New Delhi, May 7: Food ordering and delivery platform Swiggy on Thursday said its co-founder and CTO Rahul Jaimini will move away from active role in the company during the month to pursue another entrepreneurial venture.

Jaimini will be joining Pesto Tech, a career accelerator start-up, as their co-founder, Swiggy said in a statement.

He will continue to be a shareholder and board member of Swiggy, it added.

Functions currently led by Rahul, including platform engineering, analytics, IT and labs, will be realigned to Dale Vaz, Head of Engineering and Data Science, who has been with the company for close to two years, the statement said.

"Technology was crucial to what we set out to build when we started Swiggy. Nandan (Reddy) and I could not have asked for a better partner to handle this aspect of the company," Swiggy co-founder and CEO Sriharsha Majety said.

It was Rahul's immense passion to 'build for the billions' that drove technological innovations that set Swiggy apart as we grew phenomenally over the years, he added.

"Working with technology that has large scale impact is what excites me, and I am grateful to have had the opportunity to do just this at Swiggy and grow tremendously over the years," Jaimini said.
