2 Muslim sisters met their Sikh brother for the first time after 1947 separation

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."

Washington, May 31: US President Donald Trump said Saturday he will delay the G7 summit scheduled to take place in June and invite other countries -- including India and Russia -- to join the meeting.

"I don't feel that as a G7 it properly represents what's going on in the world. It's a very outdated group of countries," Trump told reporters on Air Force One.

He said he would like to invite Russia, South Korea, Australia and India to join an expanded summit in the fall.

It could happen in September, either before or after the UN General Assembly, Trump said, adding that "maybe I'll do it after the election."

Americans head to the polls in early November to choose a new president, with Trump keen for a return to normalcy after the coronavirus pandemic and a healthy economy as voters cast their ballots.

Describing the event as a "G-10 or G-11", Trump said he had "roughly" broached the topic with leaders of the four other countries.

Leaders from the Group of Seven, which the United States heads this year, had been scheduled to meet by videoconference in late June after COVID-19 scuttled plans to gather in-person at Camp David, the US presidential retreat outside Washington.

Trump created suspense last week, however, when he announced that he might hold the huge gathering in-person after all, "primarily at the White House" but also potentially parts of it at Camp David.

German Chancellor Angela Merkel became the first leader to decline the in-person invitation outright.

"Considering the overall pandemic situation, she cannot agree to her personal participation, to a journey to Washington," her spokesman said Saturday.

Her response followed ambivalent to positive reactions to the invitation from Britain, Canada and France.

The 65-year-old chancellor is the oldest G7 leader after Trump, who is 73. Japan's Shinzo Abe, also 65, is several months younger than Merkel. Their age puts them at higher risk from the coronavirus.

The G7 major advanced countries -- Britain, Canada, France, Germany, Italy, Japan and the United States -- hold annual meetings to discuss international economic coordination.

Russia was thrown out of what was the G8 in 2014 after it seized Ukraine's Black Sea peninsula of Crimea, an annexation never recognized by the international community.

The work of the G7 is now more important than ever as countries struggle to repair coronavirus-inflicted damage.

The White House had previously said the huge diplomatic gathering would be a "show of strength" when world economies are gradually reemerging from shutdowns.

The United States is the worst-hit country for COVID-19 infections, recording more than 1.7 million cases and over 103,680 deaths.

Patna, Jan 23: "They should go wherever they want," Bihar Chief Minister and JDU supremo Nitish Kumar said on Thursday when asked of Prashant Kishor and Pavan Verma's repeated questions about the party's stand's on the newly enacted Citizenship Act.

"It is their personal decision. They should go wherever they want. We don't have an objection. Don't look at JDU in the context of statements by some people. JDU works with determination. We have a clear stand and don't have any confusion," the Chief Minister told reporters here.

"If they have something to tell, they should come and discuss it within the party. They should go wherever they want. They have my good wishes," he said.

JDU spokesperson and national general secretary Pavan Verma has questioned his party's alliance with the BJP in Delhi Assembly polls while Kishor has more than once made his differences with the party known on the issue of the amended Citizenship Act, and National Register of Citizens.
