RSS chief pays tribute to Gauri Lankesh, Dharam Singh

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."

Bengaluru, Jul 7: Karnataka Chief Minister B S Yediyurappa on Tuesday held a meeting with a team of officials from the Union Health Ministry in Bengaluru in view of COVID-19 pandemic.

The team of Union Health Ministry officials praised the state's COVID-19 management measures.

Arti Ahuja, Additional Secretary, Ministry of Health, EMR director Ravindran met the Chief Minister during a two-day visit to the state. The team praised the State Government's efforts to gather information and identify co-morbid figures for the control of COVID-19.

During the meeting, it was discussed that in the following days, priority should be given to prevent death from COVID-19 and to provide adequate treatment for symptomatic infections.

In addition, Central team officials suggested that the COVID-19 guidelines should be followed in containment zones.

Officials informed about the steps being taken to treat COVID infected people in the state and stated that the High Flow Oxygen System is being implemented in all district hospitals and taluk hospitals in the state.  The process will be completed by August 15.

Health Minister B. Sriramulu, Medical Education Minister K. Sudhakar, Chief Secretary to Government Vijayabhaskar and other senior officials were present during the meeting.

Bengaluru, May 17: Left to itself, Karnataka will look to spring back towards normalcy under Lockdown 4.0 as the state government is on standby to resume public transport services from May 18, if the Centre allows it. 

Though KSRTC and BMTC have been preparing for resumption of services, officials in the two corporations told DH that they cannot make a move till the government makes a decision.

Transport Commissioner N Shivakumar said the department will take a decision based on the state government's orders. "The government will take a call on buses as well as taxi and other transport services," he said.

Senior officials in the state government said Deputy Chief Minister and Transport Minister Laxman Savadi has written to Union Minister for Road Transport and Highways Nitin Gadkari seeking a nod for resumption of the services. 

Transport Secretary Gaurav Gupta has written a separate letter to his counterpart in the Union government requesting permission to operate public transport. "The state government wants the services to open. The official has listed out the steps the corporations will take to ensure social distancing other steps that will be taken to check spread of Coronavirus," a source said.

The B S Yediyurappa administration has been bullish on easing lockdown restrictions. 

If the Centre empowers the states to define Lockdown 4.0, Karnataka is likely to do away with the red-orange-green zoning of districts and allow public services to resume, except in COVID-19 containment zones. The government is also likely to redefine its containment strategy by micromanaging localities where COVID-19 cases are reported, without letting life in an entire district get affected. 

The government has already shown willingness to allow hotels and gyms to open after May 17 subject to social distancing norms and restrictions. In fact, the government has proposed to allow the resumption of all economic activities in standalone establishments. The government, however, is not keen on opening malls, theatres, diners and establishments that have centralized air conditioning. 

“Everything depends on the Centre,” Deputy Chief Minister CN Ashwath Narayan said. “Our only stand is that the red zone should be treated at par with the other zone when it comes to relaxation.”
