40 militant groups were operating in Pakistan: Imran Khan

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."

London, Apr 27: British Prime Minister Boris Johnson returns to work on Monday more than three weeks after being hospitalised for the coronavirus and spending three days in intensive care.

Johnson, one of the highest-profile people to have contracted the virus, returned to 10 Downing Street on Sunday evening and will chair a meeting on Monday morning of the coronavirus "war cabinet", his colleagues confirmed.

Dominic Raab, the foreign secretary who has deputised in Johnson's absence, told the BBC on Sunday that his return would be a "boost for the government and a boost for the country".

Raab also claimed the prime minister was "raring to go".

Johnson, 55, was admitted to hospital on April 5 suffering from "persistent symptoms" of the deadly disease.

His condition worsened and he later admitted after being put in intensive care that "things could have gone either way".

He was discharged on April 12 and has been recuperating at his official residence, west of London.

In a video message after leaving hospital, Johnson thanked "Jenny from New Zealand and Luis from Portugal" for helping him recover.

On medical advice, he has not been doing official government work during his convalescence but has spoken to Queen Elizabeth and US President Donald Trump on the phone.

The British leader was diagnosed with the virus late last month but initially stayed at Downing Street and was filmed taking part in a round of applause for health workers in the days before he went to hospital.

Chennai, Jan 19: Amid ongoing nationwide protests against Citizenship (Amendment) Act, 2019, finance minister Nirmala Sitharaman on Sunday said that as many as 2838 people from Pakistan were given citizenship during the last six years.

"In the last six years, as many as 2838 Pakistani refugees, 914 Afghan refugees, 172 Bangladeshi refugees including Muslims have been given Indian citizenship. From 1964 to 2008, more than 4,00,000 Tamils (from Sri Lanka) have been given Indian citizenship," Sitharaman said at 'Programme on Citizenship (Amendment) Act, 2019' event here.

She added, "Till 2014, over 566 Muslims from Pakistan, Bangladesh and Afghanistan were given Indian citizenship. During 2016-18 under Modi government, around 1595 Pakistani migrants and 391 Afghanistani Muslims were given Indian citizenship."

The minister, further, said, "It was also during the same period in 2016, that Adnan Sami was given Indian citizenship, this is an example."    

Sitharaman added that people who came from East Pakistan have been settled at various camps in the country.

"They are still there and it's been 50-60 years now. If you visit these camps, your heart will cry. The situation is the same with Sri Lankan refugees who continue to live in camps. They're barred from getting basic facilities," she said.

Asserting that the government is not snatching away anyone's citizenship, the BJP leader said: "This Citizenship (Amendment) Act is an attempt to provide people with a better life. We are not snatching away anyone's citizenship, we are only providing them that."

"The National Population Register (NPR) will be updated every 10 years and is not involved with the National Register of Citizens (NRC). Some are involved in raising false allegations and triggering people unnecessarily without any base," she added.
