Modi govt appoints Arnab Goswami, Ram Bahadur, 2 other saffronists as members of NMML

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."

Panic gripped big tech firms like Facebook and Twitter which decided to close their offices from Seattle to London as more employees tested positive for the new coronavirus.

Facebook shut its three London offices till Monday after an employee was diagnosed with COVID-19.

The social networking giant told nearly 3,000 employees in London to work from home after an employee, who is based in Singapore but visited the London offices between February 24-26, was diagnosed with the new coronavirus, Sky News reported on Friday.

"An employee based in our Singapore office who has been diagnosed with COVID-19 visited our London offices on February 24-26.

"We are therefore closing our London offices until Monday for deep cleaning and employees are working from home until then," the company said in a statement.

There have been 163 cases of coronavirus so far in the UK.

Earlier, Facebook recommended all its Bay Area employees in the US to work from home. The latest precautions come after San Francisco announced its first two coronavirus cases on Thursday.

Facebook has also shut its Seattle office until Monday after one of its contractors was confirmed to be infected with the virus. The infected contractor last visited the Facebook office on February 21. King County health officials said all Facebook sites should work from home until March 31.

Twitter shut its Seattle office for a 'deep clean' after an employee developed COVID-19 like symptoms though final result was still awaited.

"A Seattle-based employee has been advised by doctor about likely COVID-19, though still awaiting the final testing," Twitter said in a tweet on Friday.

"While the employee has not been at a Twitter office for several weeks and hasn't been in contact w/others, we're closing our Seattle office to deep clean," the company added.

According to The Seattle Times, at least 14 people have died due to COVID-19 in Washington State till date.

Amazon, Microsoft, Google and Facebook have advised their employees in Washington State to work from home.

Apple has reportedly suggested its employees at California campuses to work from home as an "extra precaution" while new coronavirus cases spread on the west coast in the US, especially Seattle area.

Apple's flagship developers' conference WWDC 2020 in June is also at the risk of getting cancelled as the Santa Clara public health department has warned against large public gatherings. The event draws nearly 5,000 developers from across the world.

The US death toll from the new coronavirus has climbed to 14, according to Johns Hopkins' tracker, with 329 cases reported across the country.

New Delhi, Feb 24: India and the US are committed to defend their people from radical islamic terrorism, resolved to significantly expand defence ties and are working on a "fantastic" trade deal, said US President Donald Trump on Monday while asserting that his country "loves" and is "loyal" to India.

Addressing a huge crowd at 'Namaste Trump' event at the Motera stadium here, the US president, accompanied by his wife Melania and Prime Minister Narendra Modi, talked about India's great tradition of embracing individual freedom, rule of law, dignity of every human being and where people worship side-by-side in harmony.

On his maiden visit, Trump, who was welcomed by Modi on his arrival here, said his country will remain a "loyal" friend of India and called the Prime Minister an "exceptional leader" who works day and night for the country.

"India and the US are committed to fight terrorists and their ideology; that is why my government is working with Pakistan to crack down on terror groups," Trump said in the presence of his family -- daughter Ivanka, son-in-law Jared Kushner-- and top brass of his administration.

"The US will always be faithful and loyal friend of India. Thank you for the spectacular welcome," he added.

He also announced that the two countries will firm up defence deals worth USD 3 billion on Tuesday and that the US will become India's premier defence partner.

"India and US have natural and enduring friendship," Trump said to a cheering crowd.

"We are quickly revitalising our alliances all around world," he said.

Trump said both countries are working on a "fantastic trade" deal, and observed that Modi is a "tough negotiator".

The US president also heaped praises on Modi, saying the Prime Minister is a "living proof" of what an Indian can achieve with hard work as Trump referred to his humble background as a tea-seller, who had a landslide win in the 2019 Lok Sabha polls.

On his part, Modi welcomed Trump to "world's largest democracy" and said a "new history" was being created.

Modi also praised Trump's leadership in containing terrorism.

Trump said as the world's largest economy, India gives hope to all humanity and has become an economic giant.

"There is a difference between a nation that rises by coercion and one that rises by setting its people free -- that is India. India and the US have natural and enduring friendship," he said.

He also touched on India's cultural diversity and riches as he highlighted the success of its blockbuster movies like DDLJ (Dilwale Dulhania Le Jayenge) and Sholay, and its sporting icons like Sachin Tedulkar and Virat Kohli.

He highlighted the boom in the US economy under his presidency and added that India will soon be home to the biggest middle class as it will eliminate extreme poverty in in next 10 years.

On his part, Modi said ties between India and the US are no longer just another partnership but have touched far greater heights.

Welcoming Trump, he said a "new history" is being created.

Visit of President Trump to India with his family shows strong ties between India and the US, said Modi.
