Rains lash parts of Saudi Arabia; severe weather claims 14 lives

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."

New Delhi, Jan 16: In trouble brewing for the Gautam Adani-led M/S Adani Enterprises, the Central Bureau of Investigation (CBI) on Thursday said that it has registered a case against former officials of the National Co-operative Consumer Federation (NCCF) and others over alleged irregularities in supply of coal to the Andhra Pradesh Power Generation Corporation (APGENCO) in 2010.

The CBI in its FIR has named Virendra Singh, the then Chairman of the NCCF, G P Gupta, the then MD of the NCCF, S C Singhal, the then Senior Advisor of NCCF, Adani Enterprises Ltd and other unknown public servants and others for criminal conspiracy, cheating and criminal misconduct by public servants.

According to CBI, the case was filed on Wednesday after the preliminary enquiry revealed the crime by the officials named in the FIR and the Adani Enterprises was found to be true.

The FIR alleged that on June 26, 2010, APGENCO floated a tender enquiry for supply of six lakh metric tonnes of imported coal "on free on rail destination" basis to Dr Narla Tata Rao Thermal Station (NTTPS), Vijaywada and Rayalasaleema Thermal Power Plant (RTTP), Kadapa, Andhra Pradesh/RTPP via Kakinada-Vizag-Chennai-Krishnapatnam or any other ports

The same was forwarded by the Chief Engineer, APGENCO to seven PSUs -- PEC Limited, STC Limited, MSTC Limited, NCCF, MMTC, Coal India Limited and SCCL Limited.

The FIR alleged that during the probe, the Adani Enterprises used a proxy company to get the supply contract. It said, "NCCF received bids from six companies -- Adani Enterprises Ltd, Maheshwari Brothers Coal Limited (MBCL), Vyom Trade Links Pvt. Ltd, Swarana Projects Pvt. Ltd, Gupta Coal India Ltd and Kyori Oremen Ltd.

During investigation it was found that Gupta Coal India Ltd had quoted the NCCF margin of 11.3 percent, while the MBCL quoted the margin of 2.25 percent and rest did not quote any margin to the NCCF.

The FIR said the quotes of the Gupta Coal India Ltd, Kyori Oremen Ltd and Swarana Projects Pvt. Ltd were rejected by the NCCF as they were not found to be fulfilling the tender conditions.

"Post tender negotiation was done by senior officials of NCCF to give undue favour to Adani Enterprises Ltd despite it not qualifing the tender (terms)," the FIR said, adding instead of cancelling the bid of Adani Enterprise Ltd, senior management of NCCF conveyed the offer margin to the company through one of its representative -- Munish Sehgal, who was sitting in the NCCF head office. It is prima facie evident that when the bids were being processed at NCCF head office in Delhi, a representative of Adani Enterprises Ltd. was informed regarding their imminent rejection due to non-submission of NCCF margin and also that MBCL was eligible bidder quoted 2.25 percent margin," it alleged.

The CBI in its FIR, further alleged that Adani Enterprises Ltd. had given an unsecured loan of Rs 16.81 crore to Vyom Trade Links Ltd in 2008-09. "And further it was revealed that the bank guarantees of the Adani Enterprises Ltd. and Vyom Trade Links Ltd. were issues by the same branch of the State Bank of India and at the same time," it said.

"It was clear that Adani Enterprises Ltd. presented Vyom Trade Links Ltd. as a proxy company in this particular tender and Vyom Trade Links Ltd. later withdrew its offer on flimsy ground," the CBI FIR said.

"The aforesaid acts of commissions and omissions on the part of the senior management of the NCCF disclose that during their tenure, they acted in a manner unbecoming of public servants and committed irregularities by way of manipulation in the selection of bidders, thereby giving undue favours to Adani Enterprises Ltd. in award of work for supply of coal to APGENCO despite its disqualification," it added.

Jul 2: Democratic presidential candidate and former US vice-president Joe Biden has said that if he wins the November elections, strengthening the relationship with India which is America’s "natural partner", will be a high priority for his administration.

"India needs to be a partner in the region for our safety's sake and quite frankly for theirs," he said in response to a question on India-US relationship during a virtual fundraiser event on Wednesday.

At the fundraiser hosted by Chairman and CEO of Beacon Capital Partners Alan Leventhal, the former vice president said that India and the United States were natural partners.

"That partnership, a strategic partnership, is necessary and important in our security," Biden said when asked by an attendee whether India is critical to the US' national security.

Referring to his eight years as the vice president, he said, "In our administration, I was proud to play a role more than a decade ago in securing Congressional approval for the US-India Civil Nuclear Agreement, which is a big deal".

"Helping open the door to great progress in our relationship and strengthening our strategic partnership with India was a high priority in the Obama-Biden administration and will be a high priority if I'm elected president,” Biden said.

Both as the vice president and a senator from Delaware, he was a big supporter of India-US relationship.

About the November polls, Biden said that the character of the country is on the ballot. The upcoming election is the most important poll of a lifetime and that the country is currently engaged in a battle for its soul, he claimed.

Biden also slammed President Donald Trump and his administration over the handling of the coronavirus pandemic.

"Trump ignored warnings from the very beginning, refused to prepare and failed to protect the country. Not just now but throughout his presidency, undermining the very core pillars of ours, what I would argue, moral and economic strength.

"I really do believe that our country is crying out for leadership and maybe even more important, some healing. Today, we have an enormous opportunity not only to rebuild but to build back better than before. To build a better future. That's what America does," he added.
