Gorakhpur tragedy: Dr Kafeel Khan slams Yogi Adityanath for telling ‘blatant lies’

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."

Thiruvananthapuram, Feb 29: With Saudi Arabia indefinitely suspending visas for visit to Islam's holiest site for the Umrah pilgrimage in the wake of coronavirus outbreak, more than 10,000 people in the state who are awaiting their turn this year for the annual Hajj pilgrimage are a worried lot.

"This year more than 10,000 people in Kerala have been cleared by the Hajj committee," said C Muhammed Faizy, chairman, Kerala State Hajj Committee.

"There is no cause of worry. We hope that during the time of the pilgrimage, the travel restriction by Saudi Arabia will be lifted," he said.

Umrah is a pilgrimage to the holy site that can be undertaken at any time of the year, while the annual Hajj pilgrimage has specific months according to the lunar calendar.

"The move by the Saudi Arabian Government to impose travel restriction was due to the outbreak of coronavirus. It is a preventive step to contain it. In such large gatherings, if one person is affected, it will spread to others. So we fully understand the concerns of the Saudi Government," Muhammed Faizy added.

He said that the Hajj Committee only processes the requests of annual Hajj visit pilgrims and not Umrah.

"This year we expect the Hajj pilgrimage season to be from June to August after Ramzan. But it may vary according to the Ramzan date. We are yet to get any official correspondence from the Saudi Government regarding travel restrictions," he added.

The Saudi Arabian Government suspended visas for tourists from countries affected by the coronavirus, with many having to cancel their Umrah pilgrimage at the last minute.
