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."

An Indian Haj subsidy that did not exist!
Thank you Prime Minister Modi for ending Haj subsidy that never existed.
I completely welcome this move making the announcement, minister Mukhtar Abbas Naqvi said: “We believe in empowerment without appeasement.”Naqvi did not elaborate what he meant by “appeasement” but for decades, Haj subsidy remained a whip in the hands of right-wing parties to attack political rivals. Bharatiya Janata Party to embarrass rivals by accusing them of “appeasing” Muslims by subsiding expenses involved in the pilgrimage to Makkah and Madina. Angered by this attack, several Muslims have been demanding an end to the subsidy.
However, it is important to understand what this subsidy was and whether Muslims actually benefitted from it. In 2016-17, the government budgeted Rs 4.5 billion subsidy for around 100,000 Muslims who performed Haj last year. Each pilgrim paid around Rs 220,000 (amount varies each year) for airfare; stay in Makkah and Madina and for miscellaneous expenses. This money is paid to government-managed Haj committees which then transfers this money to other agencies. In other words, each Muslim pays for his/her own Haj expenses.
A significant chunk of money paid by Muslims goes to India’s government-owned national carrier Air India which enjoys a virtual monopoly on Haj circuit. The airline picks up passengers from around a dozen cities and flies them to Jeddah. The Air India inflates India-Jeddah tickets during the Haj season. This so-called government subsidy is used to pay for tickets that are always higher than the prevailing airfare charged by other airlines. A breakdown would show that an Air India ticket to Jeddah would cost more than a trip to Los Angeles from India. Essentially, the government takes money from one pocket and puts it back in another. Muslim have always demanded global tenders for Haj flights and for providing accommodation in Makkah and Madina..
However, while Naqvi sought to take a high moral ground by claiming that his party appeases no section of the society, his own government spends billions of rupees on organizing Hindu pilgrimages every year
Naqvi saab, this is what you learnt in Madrasa? U r Back-Stabbing Muslims. There is no 1% quality of muslim in you. After joining BJP you have lost it. First learn humanity. Almighty will give answers for all problems you have created for others.
