Development became vibrant movement over last 4 years, claims PM Modi

London/Milan, Jun 2: World Health Organization experts and a range of other scientists said on Monday there was no evidence to support an assertion by a high profile Italian doctor that the coronavirus causing the COVID-19 pandemic has been losing potency.

Professor Alberto Zangrillo, head of intensive care at Italy's San Raffaele Hospital in Lombardy, which bore the brunt of Italy's COVID-19 epidemic, on Sunday told state television that the new coronavirus "clinically no longer exists".

But WHO epidemiologist Maria Van Kerkhove, as well as several other experts on viruses and infectious diseases, said Zangrillo's comments were not supported by scientific evidence.

There is no data to show the new coronavirus is changing significantly, either in its form of transmission or in the severity of the disease it causes, they said.

"In terms of transmissibility, that has not changed, in terms of severity, that has not changed," Van Kerkhove told reporters.

It is not unusual for viruses to mutate and adapt as they spread, and the debate on Monday highlights how scientists are monitoring and tracking the new virus. The COVID-19 pandemic has so far killed more than 370,000 people and infected more than 6 million.

Martin Hibberd, a professor of emerging infectious disease at the London School of Hygiene & Tropical Medicine, said major studies looking at genetic changes in the SARS-CoV-2 virus that causes COVID-19 did not support the idea that it was becoming less potent, or weakening in any way.

"With data from more than 35,000 whole virus genomes, there is currently no evidence that there is any significant difference relating to severity," he said in an emailed comment.

Zangrillo, well known in Italy as the personal doctor of former Prime Minister Silvio Berlusconi, said his comments were backed up by a study conducted by a fellow scientist, Massimo Clementi, which Zangrillo said would be published next week.

Zangrillo told Reuters: "We have never said that the virus has changed, we said that the interaction between the virus and the host has definitely changed."

He said this could be due either to different characteristics of the virus, which he said they had not yet identified, or different characteristics in those infected.

The study by Clementi, who is director of the microbiology and virology laboratory of San Raffaele, compared virus samples from COVID-19 patients at the Milan-based hospital in March with samples from patients with the disease in May.

"The result was unambiguous: an extremely significant difference between the viral load of patients admitted in March compared to" those admitted last month, Zangrillo said.

Oscar MacLean, an expert at the University of Glasgow's Centre for Virus Research, said suggestions that the virus was weakening were "not supported by anything in the scientific literature and also seem fairly implausible on genetic grounds."

Jan 22: Microsoft Corp’s chief executive officer said he worries that mistrust between the US and China will increase technology costs and hurt economic growth at a critical time.

Using the $470 billion semiconductor industry as an example of a sector that is already globally interconnected, Satya Nadella said the two countries will have to find ways to work together, rather than creating different supply chains for each country.

“All you are doing is increasing transaction costs for everybody if you completely separate,” Nadella said in an interview with Bloomberg News Editor-in-Chief John Micklethwait at Bloomberg’s The Year Ahead conference in Davos. That’s a concern as the executive said the world is on the cusp of a revolution around technology and artificial intelligence.

“If we take steps back in trust or increase transaction costs around technology, all we are doing is sacrificing global economic growth,” he said.

The agreement signed last week between the US and China was “not sufficient,” said Nadella, but represented “progress” on the issue of intellectual property protections for US technology companies working with China.

Nadella said he worries about the development of two separate internets, noting that to some degree they already exist “and they will get amplified in the future” with massive technology companies already in place in China.

The viewpoint clashes with Microsoft co-founder Bill Gates, who has been sceptical about the idea that ongoing US-China trade tensions could ever lead to a bifurcated system of two internets.

China and the US are the two leading AI superpowers, however the cooling political relations between them have slowed the international collaboration.

Nadella also warned that countries that fail to attract immigrants will lose out as the global tech industry continues to grow. The CEO has previously voiced concern about India’s Citizenship Amendment Act, calling it “sad.”

“However, Nadella said he remained hopeful.

“The fact that there is a 70-year history of nation-building, I think it’s a very strong foundation. I grew up in that country. I’m proud of that heritage. I’m influenced by that experience.”

Mumbai, Feb 6: The Reserve Bank of India, for the second straight time, on Thursday kept its key policy rate unchanged at 5.15 per cent, maintaining its accommodative policy stance as long as it was necessary to revive growth.

The central bank retained GDP growth at 5 per cent for 2019-20 and pegged it at 6 per cent for the next fiscal.

"Economic activity remains subdued and the few indicators that have moved up recently are yet to gain traction in a more broad-based manner. Given the evolving growth-inflation dynamics, the MPC felt it appropriate to maintain status quo,” the Monetary Policy Committee (MPC) said.

The six-member committee voted unanimously to hold rates, but also said that there is “policy space available for further action”.

Between February and October 2019, the RBI had reduced repo rate by 135 basis points.
