Trump calls Modi 'Father of India', says he brought the country together

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."

New Delhi, Jun 18: India on Wednesday took strong exception to China claiming sovereignty over the Galwan Valley in eastern Ladakh, saying its "exaggerated and untenable claims" are contrary to the understanding reached on the issue between the two sides.

Ministry of External Affairs Spokesperson Anurag Srivastava's response came after China claimed that the Galwan Valley in eastern Ladakh is a part of its territory.

"As we have conveyed earlier today, External Affairs Minister and the State Councillor and Foreign Minister of China had a phone conversation on recent developments in Ladakh," Srivastava said late Wednesday night.

"Both sides have agreed that the overall situation should be handled in a responsible manner and that the understandings reached between Senior Commanders on 6th June should be implemented sincerely. Making exaggerated and untenable claims is contrary to this understanding," he said.

Earlier on Wednesday, India delivered a strong message to China that the "unprecedented" incident in the Galwan Valley will have a "serious impact" on the bilateral relationship and held the "pre-meditated" action by Chinese army directly responsible for the violence that left 20 Indian Army personnel dead.

In a telephonic conversation, External Affairs Minister Jaishankar conveyed to his Chinese counterpart Wang Wi India's protest in the "strongest terms" and said the Chinese side should reassess its actions and take corrective steps, the Ministry of External Affairs said.

The Chinese Foreign Ministry, in a statement, said the two sides agreed to "cool down the situation on the ground as soon as possible", and maintain peace and tranquillity in the border area in accordance with the agreement reached so far between the two countries.

The clash in Galwan Valley on Monday night is the biggest confrontation between the two militaries after their 1967 clashes in Nathu La in 1967 when India lost around 80 soldiers while over 300 Chinese army personnel were killed.

The India-China border dispute covers the 3,488-km-long LAC. China claims Arunachal Pradesh as part of southern Tibet, while India contests it.

Prior to the clashes, both sides have been asserting that pending the final resolution of the boundary issue, it is necessary to maintain peace and tranquillity in the border areas.
