Control your mind: Brahma Kumari Shivani

New Delhi, April 5: Former Karnataka chief minister HD Kumaraswamy on Sunday challenged Prime Minister Narendra Modi to offer a "credible scientific and rational" explanation for his candle-lighting call and said he is giving "meaningless tasks" to an already exhausted population.

The JD(S) leader questioned if the Prime Minister asked the nation to observe a candle-light vigil on the eve of foundation day of BJP.

"Has the PM slyly asked the nation to observe a candle light vigil on the eve of foundation day of BJP? April 6 being its foundation day, what else can explain the choice of date & time for this event? I challenge the PM to offer a credible scientific and rational explanation," Kumaraswamy tweeted.

"The government is yet to provide PPEs for doctors and make test kits affordable for the common man. Without telling the nation what concrete steps are being taken to combat COVID-19 menace, the prime minister is giving meaningless tasks to an already exhausted population," he tweeted.

"It is shameful to convert the national crisis into an event of self aggrandizement & it is beyond shameful to push the hidden agenda of his party in the face of global calamity. May sense prevail upon the PM," the JDS leader said in another tweet.

Amid a nationwide COVID-19 lockdown, Prime Minister Modi on Friday appealed to countrymen to light diyas and candles on April 5 at 9 pm to fight the darkness spread by the pandemic. He asked the people to turn off all the lights in their homes and stand at doors or balconies and light candles or diyas, torches or mobile flashlights for 9 minutes on April 5.

Last month, PM Modi had asked the people to come out in their balconies and clap and beat utensils to show appreciation for doctors, nurses and others helping fight coronavirus on 'Janata Curfew'.

Bengaluru, Jul 17: Karnataka Medical Education Minister K Sudhakar held a meeting through video conference on Thursday with private and government establishments involved in testing and treatment of COVID-19 in the state.

A total of 51,422 cases including 19,729 recoveries and 1,032 deaths were reported in the state till yesterday.

On the same day, K Sudhakar also paid a surprise visit to the Bengaluru's CV Raman Hospital and urged the administration to follow COVID-19 guidelines properly. He also took stock of the hospital's preparedness to fight the deadly virus.

"Surprise visits will continue. I will be in touch with every lab and get the right number of tests done on a daily basis," the minister said while speaking to the media.

He also urged the people who have recovered from coronavirus to donate their plasma to save other lives, adding that donors will receive a reward of Rs 5,000 as a token of appreciation.

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."
