Hardik Patel wants fans to look at Sunny Leone in same light as Sridevi, Madhuri Dixit

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, Jan 12: The US State Department has described the recent visit of envoys of 15 countries to Jammu and Kashmir as an "important step" but expressed concern over the continued detention of political leaders and restrictions on internet in the region.

Alice Wells, the Acting Assistant Secretary of State for South Asia, tweeted on Saturday that she was "closely following" the visit of the envoys to Kashmir, describing it an "important step".

Wells, who will be visiting India this week, added: "We remain concerned by detention of political leaders and residents and Internet restrictions. We look forward to a return to normalcy."

The group of diplomats made a two-day visit to the Union Territory on Thursday and Friday to see the conditions thereafter Jammu and Kashmir's special constitutional status was removed last August.

While some US politicians and media have criticised the action by Prime Minister Narendra Modi's government, the US has officially appeared to support the abrogation of the Constitution's Article 370 on the special status.

Last October, Wells told the House of Representatives Subcommittee on Asia and the Pacific that the State Department supported the objectives behind it, while not directly mentioning the abrogation.

"The Indian government has argued that its decision on Article 370 was driven by a desire to increase economic development, reduce corruption, and uniformly apply all national laws in Jammu and Kashmir, particularly in regard to women and minorities.

"While we support these objectives, the Department remains concerned about the situation in the Kashmir Valley, where daily life for the nearly eight million residents has been severely impacted since August 5," she had said.

Washington has banked on India's democratic institutions - the judiciary and public debates - being able to steer the country.

Bearing this out, the Supreme Court last week ordered the government to review its decision to shut down the internet in Kashmir, which it declared was a fundamental right, thus taking a step to address Wells's concern.

New Delhi, Jan 3: US aviation regulator Federal Aviation Administration on Thursday warned America's airlines and their pilots that there is risk involved in operating flights in Pakistan airspace due to "extremist or militant activity", according to an official document.

"Exercise caution during flight operations. There is a risk to US civil aviation operating in the territory and airspace of Pakistan due to extremist/militant activity," said the US Federal Aviation Administration (FAA) in a notice to airmen (NOTAM) dated December 30, 2019.

The NOTAM is applicable to all US-based airlines and US-based pilots.

The US regulator said in its NOTAM that there continues to be a risk to US civil aviation sector from attacks against airports and aircraft in Pakistan, particularly for aircraft on the ground and aircraft operating at low altitudes, including during the arrival and departure phases of flights.

"The ongoing presence of extremist/militant elements operating in Pakistan poses a continued risk to US civil aviation from small-arms fire, complex attacks against airports, indirect weapons fire, and anti-aircraft fire, any of which could occur with little or no warning," it said.

The FAA said that while, to date, there have been no reports of man-portable air defense systems or Manpads being used against the civil aviation sector in Pakistan, some extremist or terrorist groups operating there are suspected of having access to these Manpads.

"As a result, there is potential risk for extremists/militants to target civil aviation in Pakistan with Manpads," it said.

The regulator added that pilots or airlines must report safety or security incidents - which may happen in Pakistan - to the FAA.

Pakistan on July 16 last year opened its airspace for India after about five months of restrictions imposed in the wake of a standoff with New Delhi.

Following the Balakot airstrikes by the Indian Air Force, Pakistan had closed its airspace on February 26 last year.

Pakistan in October last year had denied India's request to allow Prime Minister Narendra Modi's VVIP flight to use its airspace for his visit to Saudi Arabia over the Jammu and Kashmir issue.
