NKorea missile test: Trump asks China to end Pyongyang's 'nonsense'

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."

Beijing, Mar 6: World health officials have warned that countries are not taking the coronavirus crisis seriously enough, as outbreaks surged across Europe and in the United States where medical workers sounded warnings over a "disturbing" lack of hospital preparedness.

The World Health Organization warned Thursday that a "long list" of countries were not showing "the level of political commitment" needed to "match the level of the threat we all face".

"This is not a drill," WHO chief Tedros Adhanom Ghebreyesus told reporters.

"This epidemic is a threat for every country, rich and poor."

Tedros called on the heads of government in every country to take charge of the response and "coordinate all sectors", rather than leaving it to health ministries.

What is needed, he said, is "aggressive preparedness."

Langkawi, Jan 20: Malaysia will not take retaliatory trade action against India over its boycott of palm oil purchases amid a political row between the two countries, Prime Minister Mahathir Mohamad said on Monday.

India, the world’s largest edible oil buyer, this month effectively halted imports from its largest supplier and the world’s second-biggest producer in response to comments from Mahathir attacking India’s domestic policies.

“We are too small to take retaliatory action,” Mahathir told reporters in Langkawi, a resort island off the western coast of Malaysia. “We have to find ways and means to overcome that,” he added.

The 94-year-old premier of Muslim-majority Malaysia has criticised New Delhi’s new religion-based citizenship law and also accused India of invading the disputed region of Kashmir.

Mahathir again criticised India’s citizenship law on Monday, saying he believed it was “grossly unfair”.

India has been Malaysia’s largest palm oil market for the past five years, presenting the Southeast Asian country with a major challenge in finding new buyers for its palm oil.

Benchmark Malaysian palm futures fell nearly 10% last week, their biggest weekly decline in more than 11 years.

New Delhi is also unhappy with Malaysia’s refusal to revoke permanent resident status for controversial Indian Islamic preacher Zakir Naik, who has lived in Malaysia for about three years and faces charges of money laundering and hate speech in India.

Mahathir said even if the Indian government guarantees a fair trial, Naik faces the real threat of vigilante action and that Malaysia will only relocate the preacher if it can find a third country where he would be safe.

“If we can find a place for him, we will send him out.”
