BJP supremo Amit Shah to visit Mangaluru on Oct 4

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."

Belagavi, Feb 11: Tension prevailed for sometime here after a few villagers spotted four country-made pistols disposed in the garbage site by the road between Markandey Nagar – Waghavade village on Sunday. Police rushed to the spot and seized the arms which are believed to be of Portugal era.

Sources said some villagers noticed a pistol lying along with heaps of refuse. They informed Bhavakanna Patil, the owner of the agricultural field adjacent to the garbage site. Patil and the villagers checked the garbage and found three more pistols totalling four.

Police said the pistols are about 50 to 60 years old. Going by their condition, all rusted, it is believed that they were left unused for a long time. The Belagavi rural police who have filed a suo motu case related to the incident are getting into the skin of case to trace the owners and those who disposed them in the garbage pit. 

According to preliminary investigation, it is learnt that such pistols were in vogue during Portugal rule in Goa. There are chances that those who inherited the arms may have disposed it for the fear of possessing weapon illegally. The chances of some notorious people who reside in the vicinity near Waghavade and surrounding areas, where burglaries and dacoity are frequently reported, disposing the arms due to the fear of police also cannot be ignored. Police Commissioner Lokesh Kumar was not available for comments.

Thiruvananthapuram, Apr 27: Kerala Chief Minister Pinarayi Vijayan on Sunday said the issue of return of Non-Resident Keralites (NRKs) to the state has been taken up with the Centre and the state government is awaiting a favourable response.

The Chief Minister announced that the Department of Non-Resident Keralites Affairs has opened online registration for such NRKs.
