Development became vibrant movement over last 4 years, claims PM 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."

Jammu & Kashmir, Feb 7: Former Jammu and Kashmir chief ministers Mehbooba Mufti and Omar Abdullah, besides two political stalwarts from NC and its arch-rival PDP were booked under the stringent Public Safety Act (PSA) by the administration on Thursday, officials said.

A magistrate accompanied by police served the order to Mufti at the bungalow where she has been detained, the officials said.

Abdullah was also booked under the PSA, they said.

National Conference general secretary and former minister Ali Mohammed Sagar, who wields a support base in downtown city, was served with a PSA notice public order by the authorities.

Similarly, senior PDP leader Sartaj Madani was booked under the PSA. Madani is the maternal uncle of former chief minister Mehbooba Mufti.

Both Sagar and Madani were detained in the aftermath of August 5 crackdown by the Centre on politicians following abrogation of special status of the erstwhile state, besides its bifurcation into two union territories.

Their six-month preventive custody was ending on Thursday.

Earlier, the officials had said that former NC legislator Bashir Ahmed Veeri was also booked under the PSA but later it turned out that he had been released.

May 10: Delhi recorded five more deaths due to coronavirus, while 381 fresh cases of the virus were reported, the city government said on Sunday.

With the fresh cases, the virus tally in the national capital has climbed to 6,923.

Between midnight of May 8 and midnight of May 9, five fresh fatalities due to the virus were reported, taking the death toll to 73, the government said in its health bulletin.

While there are 4,781 active cases of the virus in the city, 2069 patients have so far recovered from COVID-19.
