'No place for hate': Satya Nadella backs Black Americans, as he did Indian Muslims

Washington, Apr 28: US President while addressing a news conference on coronavirus pandemic said his administration has launched "very serious investigations" into China's response to the novel coronavirus.

"And we are not happy with China, we are not happy with that whole situation, because we believe it could have been stopped at the source," he said. "It could have been stopped quickly and it wouldn't have spread all over the world," the BBC reported.

Trump has been critical of China as the pandemic has progressed and has frequently touted his decision to close the US borders to China in an effort to curb the outbreak. Some health experts have said the effort bought time for the US to prepare, but the Trump administration has been accused of squandering the opportunity.

"Nobody except one country can be held accountable for what happened," Trump said.

"Nobody's blaming anybody here, we're looking at a group of people that should've stopped it at the source."

The US will never forget those who were "sacrificed for a reason of incompetence or something else other than incompetence," he added.

"They" - referring to China - "could've protected the whole world - not just us - the whole world," he said.

At the starting of the conference Trump said COVID-19 cases are declining or stablising across the country.

"In all cases getting better," he said. "Really a horrible situation that we've been confronted with, but they're moving along."

He added there's a "hunger" to get back to work.

"Ensuring the health of our economy is vital to ensuring the health of our nation - these goals work in tandem."

The president has suggested an unnamed individual "a long time ago" could have stopped the "unnecessary death[s]" due to COVID-19.

"There has been so much unnecessary death in this country," he said.

"It could've been stopped and it could've been stopped short, but somebody a long time ago, it seems, decided not to do it that way and the whole world is suffering because of it."

He did not say who he was referencing and gave no other details.

Trump was asked if he has considered delaying the November presidential election.

"I never even thought of changing the date of the election," he answered. "Why would I do that? November 3rd. That's a good number."

Trump called the suggestion "made up propaganda" and said that "sleepy Joe" Biden - his presumptive Democratic rival - was likely unaware his campaign had put the statement out.

Former Vice-President Joe Biden said at a virtual fundraiser last week that he thought Trump would "try to kick back the election somehow".

The president has frequently levelled insults at his Democratic opponent by questioning the former vice-president's mental fortitude.

"I look forward to that election," Trump said.

The president responded to a question criticising Health Secretary Alex Azar's early downplaying of the disease by saying it was "unfair". He claimed Democrats did the same, including Speaker of the House of Representatives Nancy Pelosi.

"I was very fortunate through luck or whatever that we closed the border, we put a ban on China," he said.

"But I could tell you that Nancy Pelosi was dancing in the streets in Chinatown. She wanted to go, let's go out and party. That was late in February."

Back in February, Pelosi had encouraged people to visit San Francisco's Chinatown to help struggling businesses. She did not propose any parties, as the president suggested.

The city issued a stay-at-home order in March.

A reporter asked: If an American president loses more Americans over the course of six weeks than died during the entirety of the Vietnam war, does he deserve to be reelected?

Trump took the question in stride.

"So, yeah, we've lost a lot of people but if you look at what original projections were, 2.2 million, we're probably heading to 60,000 - 70,000," he said.

"It's far too many - one person is too many for this. I think we've made a lot of really good decisions," he added. "The big decision was closing the border, doing the ban on people coming in from China."

He also brings up the "unbelievable" job his administration did with ventilators.

"I think we've done a great job. And I will say this - one person is too many."

Paris, Jun 13: The coronavirus pandemic has killed 425,000 people since it emerged in China late last year, according to an AFP tally of official sources at 0130 GMT on Saturday.

A total of 425,282 deaths have now been recorded from 7,632,517 cases.

Europe has registered 186,843 deaths from 2,363,538 cases, but the epidemic is progressing most rapidly in Latin America, where there have been a total of 76,343 deaths recorded from 1,569,938 cases.

The United States remains the country with the most recorded deaths at 114,643, ahead of Brazil which on Friday became the second worst-hit nation with 41,828 deaths. Britain is next with 41,481 deaths, followed by Italy (34,223) and France (29,374).

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.
