No evidence of COVID-19 losing potency, says WHO, other health experts denying Italian doctor's claim

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."

London, Apr 7: British Prime Minister Boris Johnson was moved to the intensive care unit of a London hospital after his coronavirus symptoms worsened Monday, just a day after he was admitted for what were said to be routine tests.

Johnson was admitted to St. Thomas’ Hospital late Sunday, 10 days after he was diagnosed with COVID-19, the first major world leader to be confirmed to have the virus.

Downing Street said Johnson was conscious and did not require ventilation, but he was moved into intensive care in case he needs it later, his office said in a statement.

Britain has no official post of deputy prime minister, but Foreign Secretary Dominic Raab has been designated to take over should Johnson become incapacitated.

Hours earlier, Johnson tweeted that he was in good spirits and thanked the National Health Service for taking care of him and others with the disease.

“On the advice of my doctor, I went into hospital for some routine tests as I’m still experiencing coronavirus symptoms,″ Johnson said in the tweet. “I’m in good spirits and keeping in touch with my team, as we work together to fight this virus and keep everyone safe.″

The prime minister's spokesman said earlier Monday that Johnson had spent a comfortable night and remained in charge of government after being admitted to the hospital because his cough and fever persisted.

Johnson's spokesman, James Slack, refused to say what kind of tests Johnson was undergoing. He insisted that "the PM remains in charge of the government."

“He is receiving updates in hospital and is continuing to receive a (ministerial red) box" of files and briefing papers, Slack said.

Prime Minister Narendra Modi on Monday hoped that his British counterpart Boris Johnson, admitted to a hospital for treatment of coronavirus, finds himself in perfect health soon.

"Hang in there, Prime Minister @BorisJohnson! Hope to see you out of hospital and in perfect health very soon," the prime minister wrote on Twitter.

The 55-year-old leader had been quarantined in his Downing Street residence since being diagnosed with COVID-19 on March 26. He continued to preside at daily meetings on the outbreak until Sunday. He released several video messages during his 10 days in isolation urging Britons to stay home and observe social distancing measures to help slow the spread of the virus.

Speaking earlier at the government's daily coronavirus press briefing, Raab said Johnson was being “regularly updated," but said he had not spoken to him since Saturday.

“He's in charge, but he’ll continue to take doctors’ advice on what to do next," Raab said.

Politicians from all parties wished Johnson a quick recovery. Opposition Labour Party leader Keir Starmer tweeted: “Terribly sad news. All the country’s thoughts are with the Prime Minister and his family during this incredibly difficult time."

Johnson's fiancee, Carrie Symonds, who is pregnant, is herself recovering from coronavirus symptoms.

Johnson was admitted to the hospital as a message to the nation from Queen Elizabeth II was being broadcast Sunday evening. The 93-year-old monarch urged the public to show resolve and follow advice to stay inside.

Concerns had been growing about Johnson’s welfare ever since he posted a message Friday saying that he was feeling better, though was still feverish.

The virus causes mild to moderate symptoms in most people, but for some, especially older adults and the infirm, it can cause pneumonia and lead to death.

The government said Monday that 51,608 people had been confirmed to have the coronavirus in Britain, 5,373 of whom have died.

Derek Hill, a professor of medical imaging science at University College London, said that since COVID-19 causes difficulty breathing, one test performed on people with the disease is lung imaging with ultrasound or CT scans to see how badly they might be affected.

Hill said there are various types of breathing help, depending on the person and the difficulties.

“The reasons some people get seriously ill with COVID-19 while others have minor symptoms is not yet fully understood,″ Hill said. “But doctors managing these patients report that more men than women have serious problems, and patients who are overweight or have previous health problems are at higher risk."

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

Jan 31: Twenty-three children aged between six months and 15 years, who had been taken hostage by a murder accused after inviting them to his daughter's birthday party, were rescued late on Thursday night after police killed their captor in a village here.

The hostage drama began at Kasaria village in the afternoon and continued for about eight hours.

"The accused was killed and there were about 23 children who were rescued safely," Additional Chief Secretary (Home) Awanish Awasthi told reporters at a hurriedly called press conference at 1.20 am.

"The accused had invited the children for the birthday party of his daughter and held them hostage. It started about 5.45 pm on January 30 and continued for about eight hours," Director General of Police (DGP) O P Singh said, adding that in the entire operation they had tried to "engage" the accused and were successful.

He said the accused, identified as Subhash Batham, had initially released a six-month-old girl by handing her over to his neighbour from a balcony.

Eyewitnesses said a restive crowd gathered outside the house where the children were kept with some women wailing and praying for their safe release.

The crowd broke open the door of the house to rescue the children, they said.

As the accused opened fire, the police retaliated killing him on the spot.

In the exchange of fire, the captor's wife was injured, but none of the children suffered any injury.

A man and two policemen also suffered bullet injuries.

The motive of the accused was not known immediately.

Chief Minister Yogi Adityanath monitored the situation in Farrukhabad, which is nearly 200 km from state capital Lucknow.

"The CM as soon as he got to know about the incident called a meeting of the crisis management group and personally monitored the situation and ensured children are rescued safely," Awasthi said.

Earlier, a team of NSG (National Security Guard) commandos had taken a special aircraft to reach Farukhabad, a senior security official in Delhi said.

Police said Batham, a murder accused, seemed to be mentally unstable.

Inspector-General of Police, Kanpur Range, Mohit Agarwal, said, "The man called the children for a birthday party and held them hostage in the basement of the house. He fired six shots from inside the building."

Batham initially wanted to talk to the local MLA, but refused to speak to the leader when he arrived, Agarwal said.
