Jiah Khan death: Charges framed against Sooraj Pancholi

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."

Jehanabad, Jan 27: The police here carried out a raid at the ancestral house of anti-CAA activist Sharjeel Imam, who has been slapped with a sedition case in the national capital for alleged inflammatory speeches he gave at Shaheen Bagh and the Jamia Milia Islamia, a senior official said on Monday.

According to Superintendent of Police, Jehanabad, Manish Kumar, Imams house in Kako police station area was raided late on Sunday night following "help sought by central agencies" which are investigating the cases lodged against the JNU research scholar.

Imam was not found at his house but two of his relatives and their driver were detained for interrogation and let off thereafter, the SP said.

A graduate in computer science from IIT-Mumbai, Sharjeel Imam had shifted to Delhi for pursuing research at the Centre for Historical Studies, JNU.

He was slapped with a sedition case after his alleged speeches went viral on the social media wherein he was heard speaking about Assam's possible secession from the country in the wake of the Citienship (Amendment) Act (CAA).

Earlier, he had been booked on similar charges at a police station in Aligarh for a speech he delivered on the AMU campus.

Besides, a case under the stringent anti-terror law UAPA has been registered against him at Assam.

Imams late father Akbar Imam was a local JD(U) leader who had unsuccessfully contested an assembly election in his lifetime.

Reacting to the developments, his distraught mother Afshan Rahim told the media, "My son is innocent. He is a bright young man and not a thief or a pickpocket. I swear in the name of God that I do not know about his whereabouts. But I can guarantee that upon learning about the cases, he will appear before the investigating agencies and fully cooperate in the probe."

She said that it has been a long time since she met her son though she had a telephonic conversation with him a few weeks ago.

"He was obviously disturbed by the CAA and fears of the National Register of Citiznes (NRC) about being implemented across the country which, he said, would affect not just Muslims but all poor people," she said.

In fact, after 15 days of Shaheen Bagh protest, he had asked the agitators there to withdraw and watch the situation for a month, and then decide on the further course of action, she said. "But they refused to relent. He was calling for a 'chakkajam' (road blockade). He is just a kid and not capable of instigating people for secession," she added.

Howrah, Jan 8: Following the 'Bharat Bandh' called by trade unions, protesters blocked railway tracks in Howrah and Kanchrapara in North 24 Parganas on Wednesday.

They raised anti-government slogans and criticised the Center for its policies. They were holding placards, posters and banners against the government.

Commuters faced difficulties as bus services were also affected. CPI (M) protesters also stopped the operation of state transport buses. In Odisha, the public agitation started around 6 am at Talcher, Bhubaneswar, Brahmapur, Bhadrak and Kendujhargarh.

Due to the protests, the following trains are detained enroute at different stations --Bhadrak-Brahmapur passenger at Bhadrak, Kendujhargarh-Bhubaneswar passenger at Kendujhargarh, Bhubaneswar-Balangir InterCity at Bhubaneswar, Howrah-Yesvantpur Express at Brahmapur, Ichhapur-Cuttack MEMU at

Brahmapur and Puri-Rourkela passenger at Bhubaneswar.

The ten central trade unions including Centre of Indian Trade Unions (CITU), Indian National Trade Union Congress (INTUC), among others have given the call for strike with a 12-point charter of demand. Trade union Bharatiya Mazdoor Sangh (BMS) is not taking part in the strike.
