BJP leader arrested after 200 cows starve to death at his gaushala in Durg

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."

Ahmedabad, Jul 23: Private schools in Gujarat have suspended online classes for an indefinite period from Thursday, after a state government order said they should not collect fees from students until the schools reopen.

In a notification issued last week, the Gujarat government directed self-financed schools in the state not to collect tuition fees from students as long as they remain shut in the wake of the COVID-19 pandemic.

It also asked these schools not to hike fees for the academic year 2020-21.

Unhappy with the move, a union of representing nearly 15,000 self-financed schools in Gujarat decided to put on hold online classes, an alternative arrangement started earlier this month for students.

Majority of these schools informed the parents through SMS on Wednesday night that there will not be any online classes for their wards from Thursday.

Self-financed School Management Association's spokesperson Dipak Rajyaguru on Thursday said almost all the self-financed schools in the state refrained from imparting online education.

"If the government believes online education is not real education, then there is no meaning of imparting such unreal education to our students. Online education will remain suspended until the government withdraws that notification," Rajyaguru said in a statement.

He said the association will also approach the high court against state government's decision.

Jatin Bharad, a prominent educationist and member of the association, said there is no alternative to online education in the present scenario.

"Self-financed schools need to pay salaries to the teachers and other staff. No state in India has taken such decision that fees cannot be collected despite conducting online classes. If we adhere to the state notification, it will be impossible for us to pay salaries and run the school.

Thus, we have decided to suspend the online classes," said Bharad said.
