Mass exodus in Florida as Hurricane Irma closes in

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 D.C., April 21: North Korea's leader, Kim Jong Un, is in grave danger following a surgery this month, according to a US intelligence official with direct knowledge.

Kim recently missed the celebration of his grandfather's birthday on April 15, which raised speculation about his well-being. He had been seen four days before that at a government meeting, according to intelligence reports cited by CNN.

The National Security Council and Office of the Director of National Intelligence have however declined to comment on the matter.

CNN has also reached out to the CIA and the State Department for comment and sought comment from the South Koreans.

Kim's absences from official state media often spark speculation and rumors about his health. North Korea has no free press and is often a black hole when it comes to the country's leadership. Analysts are heavily reliant on scanning state media dispatches and watching propaganda videos for any semblance of a clue.

Kim last appeared in North Korean state media on April 11. April 15 -- North Korea's most important holiday, the anniversary of the birth of the country's founding father, Kim Il Sung -- came and went without any official mention of Kim Jong Un's movements.

Experts are unsure of what to make of Kim's absence from any festivities celebrating his grandfather. When North Korean leaders have not shown up to these important celebrations in the past, it has portended major developments. But it has also turned out to be nothing.

"There have been a number of recent rumours about Kim's health (smoking, heart, and brain). If Kim is hospitalized, it would explain why he wasn't present on the important April 15th celebrations," said Bruce Klingner, a senior research fellow at the Heritage Foundation and former CIA deputy division chief for North Korea. "But, over the years, there have been a number of false health rumors about Kim Jong-un or his father. We'll have to wait and see."

Kim Jong Il's absence from a parade celebrating North Korea's 60th anniversary in 2008 was followed by rumblings that he was in poor health. It was later revealed he had a stroke, after which his health continued to decline until his death in 2011.

Kim Jong Un disappeared from the public eye for more than a month in 2014, which also prompted speculation about his health. He returned sporting a cane, and days later South Korean intelligence said that he had a cyst removed from his ankle.

Melbourne, July 1: Authorities will lock down around 300,000 people in suburbs north of Melbourne for a month from late on Wednesday to contain the risk of infection after two weeks of double-digit rises in new coronavirus cases in Australia's second-most populous state.

Australia has fared better than many countries in the pandemic, with around 7,830 cases and 104 deaths, but the recent surge has stoked fears of a second wave of COVID-19, echoing concerns expressed in other countries.

Globally, coronavirus cases exceeded 10 million on Sunday, a major milestone in the spread of a disease that has killed more than half a million people in seven months.

From midnight, more than 30 suburbs in Australia's second-biggest city will return to stage three restrictions, the third-strictest level in curbs to control the pandemic. That means residents will be confined to home except for grocery shopping, health appointments, work or caregiving, and exercise.

The restrictions will be accompanied by a testing blitz that authorities hope will extend to half the population of the area affected, and for which borders will be patrolled, authorities said. The measures come as curbs ease across the rest of the state of Victoria, with restaurants, gyms and cinemas reopening in recent weeks.

Victoria recorded 73 fresh cases on Tuesday from 20,682 tests, following an increase of 75 cases on Monday. State premier Daniel Andrews warned on Wednesday that the return of broader restrictions across city remained a possibility.

"If we all stick together these next four weeks, we can regain control of that community transmission ... across metropolitan Melbourne," Andrews said at a briefing. "Ultimately if I didn't shut down those postcodes I'd be shutting down all postcodes. We want to avoid that."

Victoria's spike in cases has been linked to staff members at hotels housing returned travellers for which quarantine protocols were not strictly followed. Victorian state authorities have announced an investigation into the matter.

Some other Australian states and territories are preparing to open borders, but applying limits and quarantine measures to citizens of Victoria as the school holiday season gets under way.

South Australia, the country's fifth most populous state, has had just three new cases in the past month. But citing the spike in coronavirus infections, on Tuesday it cancelled its scheduled reopening to other parts of the nation.

New South Wales (NSW), Australia's most populous state, has stopped short of closing its borders to all Victorians, but those holidaying from hotspot areas - not permitted under NSW rules - can be handed a fine of A$11,000 ($7,596) or jailed if they are detected, state authorities said.

The delays reopening internal borders cast doubts over a federal plan to set up "travel bubble" with neighbouring New Zealand that would allow movement between the two countries.
