BJP alleges Cong sponsoring ad in Pak to remove Modi

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, Apr 11: Ahead of Prime Minister Narendra Modi's meeting with chief ministers, senior Congress leader P Chidambaram on Saturday urged CMs of states where the party is in power to unanimously demand for transfer of cash to every poor family.

He said the poor have lost their jobs and have exhausted their savings. They are now standing in lines to get free food, the former Union finance minister said.

Chidambaram said remonetising the poor would cost only Rs 65,000 crore, which is economically viable.

"Chief ministers Amarinder Singh, Ashok Gehlot, Bhupesh Baghel, V Narayanasami, Uddhav Thackeray and E Palaniswani should tell the prime minister today that just as LIVES are important LIVELIHOOD of the poor is important, he tweeted.

"The poor have lost their jobs or self-employment in the last 18 days. They have exhausted their meagre savings. Many are standing in line for food," Chidambaram said.

Can the state stand by and watch them go hungry," he asked, adding that chief ministers should demand that cash be transferred to every poor family immediately.

"Remonetise the poor should be their unanimous demand," Chidambaram said.
