Venkaiah Naidu takes oath as Vice-President of India

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, May 15: Microsoft founder Bill Gates on Friday thanked Prime Minister Narendra Modi for the interaction and stressed that combating the coronavirus pandemic requires global collaboration.

"Thank you for the conversation and partnership PM Narendra Modi. Combating the pandemic requires global collaboration. India's role is key as the world works to minimize social and economic impact, and pave the way to vaccine, testing, and treatment access for all," Bill Gates said.

Prime Minister Narendra Modi on Thursday interacted with philanthropist and Microsoft co-founder Bill Gates and discussed the global response to Covid-19 and the importance of global coordination on scientific innovation to combat the pandemic.

The Prime Minister underlined the conscious approach that India has adopted in its fight against the health crisis - an approach based on ensuring public engagement through appropriate messaging, a PMO release said.

He explained how this people-centric bottom-up approach has helped win acceptability for physical distancing, respect for frontline workers, wearing of masks, maintaining proper hygiene, and respecting lockdown provisions.

They agreed that given India's willingness and capacity to contribute to global efforts, particularly for benefit of fellow developing countries, it was important for India to be included in the ongoing global discussions for coordinating responses to the pandemic.

The Prime Minister also suggested that the Gates Foundation could take the lead in analyzing the necessary changes in lifestyles, economic organisation, social behaviour, modes of disseminating education and healthcare, that would emerge in the post-Covid world, and the associated technological challenges that would need to be addressed.

He said that India would be happy to contribute to such an analytical exercise based on its own experiences.

New Delhi, May 25: Union Home Minister Amit Shah on Monday extended his greetings on the occasion of Eid-ul-Fitr and wished that the festival will bring peace and happiness to all.

"Extend my warm greetings on the occasion of Eid-ul-Fitr. May this festival bring peace and happiness in everyone's life," Shah tweeted.

Eid-ul-Fitr is being celebrated across the country on Monday.
