Pakistan: Covid-19 positive doctor exposes country's preparedness to tackle pandemic

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."

Brasilia, Jul 14: Brazil has reported new 20,286 coronavirus cases in last 24 hours taking the country's total to 1.8 million, Sputnik reported citing the health ministry.

The country's death toll has increased by 733 in the same period of time. The death toll from the infection has touched 72,833.

Over 1.1 million people have recovered from COVID-19 in Brazil since the start of the epidemic in the country, according to the health ministry.

Brazil has the second-highest coronavirus death toll, it is surpassed only by the United States.

Hong Kong, Apr 20: Oil prices collapsed to more than two-decade lows Monday as traders grow concerned that storage facilities are reaching their limits, while equities were mixed, with some support coming from signs that the coronavirus may have peaked in Europe and the United States.

US crude benchmark West Texas Intermediate briefly plunged almost 20 percent to below 15 -- its lowest since 1999 -- as stockpiles continue to build owing to a crash in demand caused by the COVID-19 pandemic.

Analysts said this month's agreement between top producers to slash output by 10 million barrels a day was having little impact on the oil crisis because of lockdowns and travel restrictions that are keeping billions of people at home.

WTI was hit particularly hard as its main US storage facilities in Cushing, Oklahoma, were filling up.

ANZ said "crude oil prices remained under pressure, as projections of weaker demand weigh on sentiment".

"Despite the OPEC+ alliance agreeing to an unprecedented cut in output, the physical market is awash with oil," it said, referring to the Organization of the Petroleum Exporting Countries and non-OPEC partners.

And AxiCorp's Stephen Innes added: "It's a dump at all cost as no one... wants delivery of oil, with Cushing storage facilities filling by the minute.

"It hasn't taken long for the market to recognise that the OPEC+ deal will not, in its present form, be enough to balance oil markets." Stock traders were in slightly more buoyant mood as governments start to consider how and when to ease lockdowns that have crippled the global economy.

Italy, Spain, France and Britain reported drops in daily death tolls and slowing infection rates.

"We are scoring points against the epidemic," said Prime Minister Edouard Philippe, while insisting "we are not out of the health crisis yet".

Meanwhile, in the US, Andrew Cuomo, governor of badly hit New York state, said the disease was "on the descent", though he cautioned it was "no time to get cocky".

Mounting evidence suggests that the lockdowns and social distancing are slowing the spread of the virus.

That has intensified planning in many countries to begin loosening curbs on movement and easing the crushing pressure on national economies.

Adding to the sense of hope was a report indicating promising research on a drug to treat coronavirus.

Hong Kong, Shanghai and Seoul were each up 0.1 percent, while Wellington added 0.4 percent.

However, Tokyo went into the break 0.9 percent lower, while Sydney and Manila dropped one percent apiece. There were also losses in Taipei, Singapore and Jakarta.

"The longer investors have to contemplate future economic issues while they wait for more countries to be on the downward slope of the pandemic curve, the more scope there is of risk assets pricing in a difficult future," Chris Iggo, of AXA Investment Managers UK, said.

Investors are keeping an eye on Washington, where Congress and the White House are working towards a 450 billion economic relief plan for small business to add to the trillions already pledged to support the economy.

Big-name companies including IBM, Netflix and Coca-Cola are due to deliver their earnings reports.
