Vande Mataram or Afzal Guru? Venkaiah Naidu asks Indians

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."

New Delhi, Jul 25: Congress leader Rahul Gandhi on Saturday accused the government of benefitting by making profits during the coronavirus-induced lockdown when people were in trouble.

He tagged a news report that claimed the Indian Railways was making profit by running 'Shramik trains' for transporting migrants during the pandemic.

"There are clouds of disease and people are in trouble, but one seeks to benefit -- this anti-people government is converting a disaster into profits and is earning," he said in a tweet in Hindi.

The news report claimed that the railways made a profit of Rs 428 crore by running Shramik special trains during the lockdown that transported migrants to their native places.

In another tweet, he lauded the efforts of the Himachal government in conducting a survey to select 'one district, one product', saying he had suggested this sometime back.

"This is a good idea. I had suggested it some time back. Its implementation will need a complete change of mindset," he said on Twitter.

He also tagged a report that stated the state Industries Department is conducting a baseline survey in all districts to select one district, one product for centrally-sponsored Micro and Small Enterprises Cluster Development Programme (MSE-CDP). 

Mar 28: A 69-year-old patient, hailing from Chullikal in Ernakulam District, passed away at Kalamasserry Medical College at 8:00am.

The patient had come from Dubai recently and was quarantined.

He arrived in Kerala on March 16 and was tested positive for Coronavirus on March 22, Medical College nodal officer A Fathahudeen said.

He was undergoing treatment for heart ailment and blood pressure. He had earlier undergone a bypass surgery.

Forty nine passengers in the flight he came are under quarantine.

A close relative and the driver who picked him up from the airport are coronavirus positive.

Since the deceased had no contact with any others in the state since his arrival, his route map was not processed.

Kerala reported 39 fresh cases of coronavirus on Friday, taking the total number of people under treatment to 164. The total number of confirmed cases from the state is 176, but, of this, 12 had recovered.

Of the 39 cases, 34 are from the worst affected northernmost district of Kasaragod, two from Kannur and one each from Thrissur, Kozhikode and Kollam.

With a positive case being reported from Kollam, all 14 districts in the state have been affected by the pandemic.

The worst affected Kasaragod has 76 positive cases, the highest and most of the affected are Non Resident Keralites from the Gulf.

A total of 1,10,299 people are under surveillence and 616 are in isolation wards of various hospitals.
