BJP's Kerala unit chief Rajasekharan sworn in as Mizoram Governor

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."

Kolkata, Jan 27: The West Bengal government on Monday tabled a resolution against the Citizenship (Amendment) Act in the Assembly.

The resolution appeals to the Union government to repeal the amended citizenship law and revoke plans to implement NRC and update NPR.

As per reports, state Parliamentary Affairs Minister Partha Chatterjee introduced the resolution in the House around 2 pm.

Three states - Kerala, Rajasthan and Punjab - have already passed resolutions against the new citizenship law.

The law has emerged as the latest flashpoint in the state, with the TMC opposing the contentious legislation tooth and nail, and the BJP pressing for its implementation.

Chennai, Feb 5: Income Tax sleuths on Wednesday raided top Tamil film actor Vijay's residence here besides conducting simultaneous searches at several premises linked to a film production house, movie financier and distributors in connection with suspected tax evasion.

The searches, which began in as many as 38 locations in Tamil Nadu, were still on and unaccounted cash of about Rs 25 crore was seized from the premises of a Tamil film financier who had faced allegations of intimidation and arm-twisting to recover money, official sources told PTI.

Also, several documents indicating substantial tax evasion has been seized, sources added.

Vijay, who was away in Cuddalore district for a film shoot, was apprised by authorities about the searches and he was en route to his residence here, they said.

So far nothing has been recovered from the actor's house and the inmates were cooperating with authorities in conducting the searches, sources said.

Raids were also on in the premises of the production house that had made Vijay's hugely successful recent Tamil movie 'Bigil.'

Further details are expected after completion of searches which is likely to continue tomorrow.

The State police has been providing security for carrying out the searches.
