Underworld don Ravi Pujari detained in SA, likely to be deported

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, May 28: With 6,566 more coronavirus cases and 194 deaths reported in the past 24 hours, India's COVID-19 tally reached 1,58,333 on Thursday, according to the Union Ministry of Health and Family Affairs.

The number of active coronavirus cases stands at 86,110, while 67,692 people have recovered and one patient has migrated, it said. The death toll due to the infection has reached 4,531 in the country.

Maharashtra is the worst affected state with 56,948 cases. Tamil Nadu has recorded as many as 18,545 cases while Gujarat and Delhi have recorded 15,195 and 15,257 coronavirus cases respectively.

New Delhi, Jan 15: The Delhi government Wednesday told the high court that execution of the death row convicts in the Nirbhaya gangrape and murder case will not take place on January 22 as a mercy plea has been filed by one of them.

The four convicts -- Vinay Sharma (26), Mukesh Kumar (32), Akshay Kumar Singh (31) and Pawan Gupta (25) -- are to be hanged on January 22 at 7 am in Tihar jail. A Delhi court had issued their death warrants on January 7.

Justices Manmohan and Sangita Dhingra Sehgal were told by the Delhi government and the Centre that the petition filed by convict Mukesh, challenging his death warrant, was premature.

The Delhi government and the prison authorities informed the court that under the rules, it will have to wait for the mercy plea to be decided before executing the death warrant.

They also said that none of the four convicts can be executed on January 22 unless the present mercy plea is decided.

The Supreme Court had on Tuesday dismissed the curative pleas of Mukesh and Vinay.

The mercy plea hearing began Wednesday morning and will continue in the afternoon.
