Trump's offer of mediation on Kashmir more than Pak's expectations: Qureshi

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."

Madrid, Jul 25: Spain is witnessing a new surge in virus" coronavirus infections with nearly a thousand cases daily, a month after lifting the pandemic lockdown.

The country is reinstating both voluntary guidelines and mandatory restrictions that it had lifted on June 21, The Washington Post reported.

Spain on Wednesday reported over 224 outbreaks and 2,622 virus" coronavirus cases. According to a report in Washington Post, the new surge is attributed primarily to seasonal farmworkers, people attending family get-togethers and nightclub partyers.

On Thursday, the health ministry reported an additional 971 cases.

"The majority are related to fruit collection and also to the spaces where measures to avoid contact are relaxed," Spain Health Minister Salvador Illa told parliament. "We have to call on citizens to not lose respect for the virus not to be afraid of it, but not to lose respect for it either."

The government of Spain lifted all restrictions put in place to combat virus" coronavirus on June 21 and declared 'a new normal'. 

The virus" coronavirus pandemic till then had killed 24,000 people and infected more than 2,70,166.

Countries around the world are witnessing the second surge of virus" coronavirus. The resurgence could threaten the economic bounce Spain was hoping to get from vacationers eager for summer fun.

The surge in cases has been greatest in the northeastern region of Catalonia with more than 7,953 new confirmed cases since July 10.

Spain's National Epidemiological Survey has predicted that the rate of increase more than doubled in the past three weeks.

Meanwhile, the Catalan government reverted to pre-June 21 confinement rules in Barcelona and a dozen other municipalities in the metropolitan area, as well as in Figueras, Vilafant, La Noguera and Lleida.

Authorities have ordered bars and restaurants to limit indoor occupancy to 50 per cent, reduced sports to fewer than 10 people, closed night clubs and gyms and blocked some cultural activities.

The epidemiologist in charge of the region's biggest hospital warned in an interview last week with the Spanish daily El Pais that the situation in the agricultural hub of Lleida, located about 100 miles west of Barcelona, "had clearly gotten out of hand."

"Nobody foresaw that there would be a number of people coming from abroad to pick fruit in unfavourable conditions and that they might be infected," said epidemiologist Magda Campins of Vall d'Hebron in Barcelona. "And when the infections began to be detected, it was hard to keep tabs on the cases and their contacts because some of them, although they should have been in isolation, got away because they needed to earn money."

Catalonia's Department of Labour, Social Affairs and Family is using a hotel in Lleida to quarantine fruit workers who test positive for COVID-19 but are unable to isolate at home.

In the capital of Madrid, which was the epicentre during the pandemic's first wave in the spring, authorities reported 710 new cases in the past week. The use of face masks is widespread, but the region has shied away from making them mandatory in public.

Madrid's regional health secretary, Enrique Ruiz Escudero, defended that position while citing an uptick in infections in the under-40 age group. He told young people not to let down their guard.

"We can't take even one step backwards. Young people have to be aware of the responsibility they have," Ruiz Escudero said in a news conference Thursday. "I ask them to use the face mask and to maintain a safe distance."

Toronto, Apr 25: Canadian Prime Minister Justin Trudeau on Thursday (local time) announced a new CAD 1.1 billion package supporting vaccine research and clinical trials as well as expanded testing capacity.

"We are putting in place an additional CAD 1.1 billion dollars for a national medical and research strategy to address COVID-19," Trudeau said during his daily novel coronavirus pandemic briefing on Thursday.

"This plan has three pillars -- research on vaccines and other treatments, support for clinical trials and expanding national testing and modelling," he added.

Trudeau pointed out that CAD 82 million of the total sum will be directed to the development of a vaccine and treatments against the virus, while CAD 471 million will go towards supporting clinical trials.

A further CAD 249 million is being allocated for expanding testing capacity and modelling, the Prime Minister added.

According to Trudeau, this funding will be allotted to a new "immunity task force" commissioned with conducting serology testing -- blood tests looking for the presence of antibodies indicative of exposure to the virus and subsequent immune response.

He said the taskforce, comprising the country's top medical experts, including Chief Public Health Officer Dr Theresa Tam, will test at least a million Canadians over the next two years.

The funding announced today comes in addition to the CAD 200 million committed for COVID-19-related research on March 11.

Trudeau has repeatedly stressed the daily constraints that much of the population is adhering to will be the new normal until a vaccine is developed.

As of Thursday, Canada has confirmed a total of 40,824 COVID-19 cases since the onset of the outbreak, out of which more than 2,000 have proven to be fatal, according to the latest figures from the country's public health agency.
