2.4 million pilgrims in final Hajj rituals as global Muslims celebrate Eid

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, Jun 17: With an increase of 10,974 new cases and 2,003 deaths in the last 24 hours, India's COVID-19 count reached 3,54,065 on Wednesday while the toll due to the virus stands at 11,903.

This includes 1,55,227 active cases and 1,86,935 cured, discharged and migrated patients, according to the Union Health Ministry.

While the spike in the number of cases has stayed below the 11-thousand mark, the death toll has increased manifold today as compared to the 380 death reported on Tuesday.

Maharashtra with 1,13,445 cases continues to be the worst-affected state in the country with 50,057 active cases while 57,851 patients have been cured and discharged in the state so far. The toll due to COVID-19 has crossed the five thousand mark and reached 5,537 in the state.

It is followed by Tamil Nadu with 48,019 and the national capital with 44,688 confirmed cases.

New Delhi, Jan 24: The Election Commission of India on Friday told the Supreme Court that its 2018 direction asking poll candidates to declare their criminal antecedents in electronic and print media has not helped curb criminalisation of politics. The poll panel suggested that instead of asking candidates to declare criminal antecedents in the media, political parties should be asked not to give tickets to candidates with criminal background.

A bench of Justices R F Nariman and S Ravindra Bhat asked the ECI to come up with a framework within one week which can help curb criminalisation of politics in nation's interest.

The top court asked the petitioner BJP leader and advocate Ashiwini Upadhyay and the poll panel to sit together and come up with suggestions which would help him in curbing criminalisation of politics.

In September 2018, a five-judge Constitution bench had unanimously held that all candidates will have to declare their criminal antecedents to the Election Commission before contesting polls and had called for a wider publicity, through print and electronic media about antecedents of candidates.
