New Zealand declares emergency

Washington, May 19: As the scientists across the world are struggling to develop a vaccine for combating coronavirus, US drugmaker Moderna announced on Monday (local time) that the phase I trial of its Covid-19 vaccine has shown positive early results.

The company is hopeful that it's vaccine could be available to the public as early as January next year. Several firms across the world are in the race to develop a vaccine for the deadly virus which has claimed over 3 lakh lives worldwide.

CNN citing Dr. Tal Zaks, Moderna's chief medical officer reported that "if future studies go well, the company's vaccine could be available to the public as early as January".

"This is absolutely good news and news that we think many have been waiting for for quite some time," Zaks was quoted as saying.

Moderna, based in Cambridge, Massachusetts announced that the vaccine developed neutralising antibodies to the virus at levels reaching or exceeding the levels seen in people who have naturally recovered from Covid-19, reported CNN.

These will be followed by phase 2 trials and phase 3 trials, which Moderna plans to start in July.

President Donald Trump had on Friday said that that the United States will be able to deliver a few hundred million doses of COVID-19 vaccine, under 'Operation Warp Speed', by the end of this year.

"I have very recently seen early data from a clinical trial with a coronavirus vaccine and this data made me feel even more confident that we'll be able to deliver a few hundred million doses of vaccine by the end of 2020 and we will do the best we can," Trump had said at a press conference at the White House on Friday.

Beijing, May 24: The Chinese virology institute in the city where COVID-19 first emerged has three live strains of bat coronavirus on-site, but none match the new contagion wreaking chaos across the world, its director has said.

Scientists think COVID-19 -- which first emerged in Wuhan and has killed some 340,000 people worldwide -- originated in bats and could have been transmitted to people via another mammal.

But the director of the Wuhan Institute of Virology told state broadcaster CGTN that claims made by US President Donald Trump and others that the virus could have leaked from the facility were "pure fabrication".

"Now we have three strains of live viruses... But their highest similarity to SARS-CoV-2 only reaches 79.8 percent," she said, referring to the coronavirus strain that causes COVID-19.

US demands immediate start to WHO review

The United States called on the World Health Organisation on Friday to begin working immediately on investigating the source of the novel coronavirus, as well as its handling of the response to the pandemic.

One of their research teams, led by Professor Shi Zhengli, has been researching bat coronaviruses since 2004 and focused on the "source tracing of SARS", the strain behind another virus outbreak nearly two decades ago.

"We know that the whole genome of SARS-CoV-2 is only 80 percent similar to that of SARS. It's an obvious difference," she said.

"So, in Professor Shi's past research, they didn't pay attention to such viruses which are less similar to the SARS virus."

Conspiracy rumours that the biosafety lab was involved in the outbreak swirled online for months before Trump and US Secretary of State Mike Pompeo brought the theory into the mainstream by claiming that there is evidence the pathogen came from the institute.

The lab has said it received samples of the then-unknown virus on December 30, determined the viral genome sequence on January 2 and submitted information on the pathogen to the WHO on January 11.

Wang said in the interview that before it received samples in December, their team had never "encountered, researched or kept the virus."

"In fact, like everyone else, we didn't even know the virus existed," she said. "How could it have leaked from our lab when we never had it?"

The World Health Organization said Washington had offered no evidence to support the "speculative" claims.

In an interview with Scientific American, Shi said the SARS-CoV-2 genome sequence did not match any of the bat coronaviruses her laboratory had previously collected and studied.

Washington, Jun 26: The United States reported more than 39,000 new coronavirus cases on Thursday, its highest-ever single-day count as the government relaxed restrictions and is downplaying the threat of the deadly virus.

According to the Washington Post, experts believe there is a troubling lack of consistent, unified messaging from President Donald Trump and Vice President Mike Pence. They have downplayed the danger and denigrated effective disease defences such as mask-wearing, testing, and social distancing.

Churches, beaches, and bars are filling up with people and so are hospital beds, the report said.

The counties home to Dallas, Phoenix, and Tampa all reported record-high averages on at least 15 straight days in June.

The hardest-hit states are California, Texas, Florida and those that thought they had the virus under control, like Utah and Oregon.

"I think the politicians are in denial," said Kami Kim, director of the Division of Infectious Disease and International Medicine at the University of South Florida.

The chief of the Division of Pediatric Infectious Diseases at the University of Utah Health, Andrew T. Pavia, is of the view that the push to reopen quickly even as cases climb sends a dangerous and inaccurate message.

"On the one hand, you get messages from politicians and the business community that we have to go, go, go and open up," he said. "On the other hand, you're seeing epidemiological indicators that we still have to be very careful."

"It's cognitive dissonance," he added.

The Trump administration has tried to downplay the rising number. Pence called concerns about another surge of infections "overblown," the product of media "fearmongering."

Some governors have followed the administration's lead, blaming rising caseloads on more testing.

Testifying before a congressional committee this week, Anthony S. Fauci, the nation's top infectious-diseases expert, said the new cases were "a disturbing surge" spurred by community transmission rather than testing.

"That's something I'm really quite concerned about," Fauci said. "A couple of days ago, there were 30,000 new infections. That's very disturbing to me."

Several states like Arizona, Arkansas, the Carolinas, Mississippi, Tennessee, Texas and Utah have recently reported new highs in the number of coronavirus patients hospitalized.

"We're seeing a 40 per cent increase in the last two weeks in hospitalizations," said Dallas County Judge Clay Jenkins (D), the jurisdiction's top elected official. "We're by far at our record numbers, and we're at record numbers in north Texas. Houston is at a record, the state is at a record." The Texas Medical Center in Houston, a massive medical complex, reported Thursday that 100 per cent of the beds in its intensive care unit are occupied.
