Oh My Gau Mata! Modi govt withdraws ban on sale of cattle for slaughter

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."

Mangaluru, May 21: A man who was quarantined in Moodbidri town of Dakshina Kannada after returning from Mumbai has reportedly committed suicide under mysterious circumstances.

The victim has been identified as Dayanand Poojary from Kadandale.

The exact reason for the suicide is not yet known. However, it is suspected that he might have resorted to the extreme step out of fear about COVID-19 and about the means of his future livelihood.

He was admitted to the quarantine facility at Kadandale school around 1 am on Thursday, May 21. Within a couple of hours he ended his life, sources said.

A case has been registered and investigations are on.

Bengaluru, Apr 10: Renowned ophthalmologist and Narayana Nethralaya Chairman Dr K Bhujang Shetty today advised those wearing contact lenses to switch to eyeglasses as a preventive measure.

“Though the facial mask is mandatory as a preventive measure against the dreaded Coronavirus, not many know that the virus can also enter the body through eyes. Wearing glasses or spectacles reduces the spread of the virus,” Dr Bhujang Shetty said.

Although it is more likely that people may catch Coronavirus infections through mouth and nose, there are chances of the virus also entering through eyes. “In a day, humans tend to touch their face and eyes almost 20 times an hour knowingly or unknowingly. Users of contact lenses end up touching their eyes and face frequently, increasing the risk of infections. Therefore, it is advisable that they switch to eyeglasses until the situation improves”, according to a release here on Friday.
