China coronavirus cases fall, but more imported from abroad

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."

UN, May 26: Countries could see a "second peak" of coronavirus cases during the first wave of the pandemic if lockdown restrictions were lifted too soon, the World Health Organization (WHO) has warned.

Mike Ryan, the WHO's head of emergencies, told a briefing on Monday that the world was "right in the middle of the first wave", the BBC reported.

He said because the disease was "still on the way up", countries need to be aware that "the disease can jump up at any time".

"We cannot make assumptions that just because the disease is on the way down now that it's going to keep going down," Ryan said.

There would be a number of months to prepare for a second peak, he added.

The stark warning comes as countries around the world start to gradually ease lockdown restrictions, allowing shops to reopen and larger groups of people to gather.

Experts have said that without a vaccine to give people immunity, infections could increase again when social-distancing measures are relaxed.

Ryan said countries where cases are declining should be using this time to develop effective trace-and-test regimes to "ensure that we continue on a downwards trajectory and we don't have an immediate second peak".

Also on Monday, Tedros Adhanom Ghebreyesus, WHO Director-General, said that a clinical trial of hydroxychloroquine (HCQ) on COVID-19 patients has come to "a temporary pause", while the safety data of the the anti-malaria drug was being reviewed.

According to the WHO chief, The Lancet medical journal on May 22 had published an observational study on HCQ and chloroquine and its effects on COVID-19 patients that have been hospitalized, reports Xinhua news agency.

The authors of the study reported that among patients receiving the drug, when used alone or with a macrolide, they estimated a higher mortality rate.

"The Executive Group of the Solidarity Trial, representing 10 of the participating countries, met on Saturday (May 23) and has agreed to review a comprehensive analysis and critical appraisal of all evidence available globally," Tedros said in a virtual press conference.

The developments come as the total number of global COVID-19 cases has increased to 5,508,904, with 346,508 deaths, according to the Johns Hopkins University.

Washington, Apr 18: The United States on Friday passed 700,000 confirmed coronavirus cases, according to a tally maintained by Johns Hopkins University.

With the highest number of cases and deaths of any country in the world, the US had recorded 700,282 cases of COVID-19 and 36,773 deaths as of 8:30 pm (0030 GMT Friday), according to the Baltimore-based university.

That marked an increase of 3,856 deaths in the past 24 hours, but that figure likely includes "probable" virus-linked deaths, which had not previously been counted.

This week, New York City said it would add 3,778 "probable" virus deaths to its official count.

The US Centers for Disease Control and Prevention gave a toll Friday night of 33,049 dead, including 4,226 probable virus-linked deaths.

The United States has seen the highest death toll in the world in the coronavirus pandemic, ahead of Italy (22,745 deaths) although its population is just a fifth of that of the US.

Spain has recorded 19,478 deaths, followed by France with 18,681.

Trump announces $19 billion relief for farmers amid COVID-19 epidemic

President Donald Trump on Friday announced a $19 billion financial rescue package to help the agriculture industry weather the staggering economic downturn sparked by measures to defeat the coronavirus.

Trump told a press conference the government "will be implementing a $19 billion relief program for our great farmers and ranchers as they cope with the fallout of the global pandemic."

The program will include direct payments to farmers, ranchers and producers who Trump said have experienced "unprecedented losses during this pandemic."

Agriculture Secretary Sonny Perdue said US farmers have been hit hard by a sharp shift in demand, as schools and restaurants close and more Americans eat at home.

That has disrupted the food supply chain, forcing farmers in many places to destroy dairy output and plow under crops that no longer have buyers.

"Having to dump milk and plow under vegetables ready to market is not only financially distressing, but it's heartbreaking as well to those who produce them," Perdue said.

Perdue said some $3 billion of the money would go to buying produce and milk from such farmers, and redistribute it to community food banks.

Millions of Americans have recently turned to food pantries for meals and groceries after losing their jobs.
