UK had contingency plans for Boris Johnson's death

Melbourne, Mar 18: Australian Prime Minister Scott Morrison on Wednesday warned its citizens not to travel abroad and banned "non-essential" gatherings of 100 people or more as the government declared the deadly coronavirus, that has infected over 450 people in the country, a "human biosecurity emergency".

Prime Minister Morrison on Wednesday said Australians should abandon all overseas travel because of the coronavirus epidemic. There have been 40 new cases since Tuesday.

Of the 454 confirmed cases in Australia, 43 have recovered and 5 have died from the COVID-19, according to the official figures.

Morrison declared a national "human biosecurity emergency" and ordered a halt to "non-essential" indoor gatherings of more than 100 people, on top of an existing ban on outdoor events of more than 500.

He said, "We haven't seen this sort of thing in Australia since the end of the First World War. This is a once-in-a-100-year-type event," Morrison said.

"Life is changing in Australia, as it is changing all around the world. Life is going to continue to change. The travel advice to every Australian is do not travel abroad. Do not go overseas."

However, schools across the country were still to remain open.

Morrison said Australia should prepare for "at least six months" of disruption as health authorities attempt to get on top of the coronavirus.

"For those of you thinking about going overseas for the school holidays, don’t. Don't go overseas," he said.

Morrison said there would be no short-term, quick fix to deal with the COVID-19 crisis in Australia, and warned that "tens of thousands of jobs" could be lost.

Responding to the panic buying, the prime minister urged the public to "Stop hoarding."

"I can't be more blunt about it. Stop it. It is not sensible, it is not helpful and it has been one of the most disappointing things I have seen in Australian behaviour in response to this crisis," he said.

On Wednesday, the New South Wales recorded a massive jump in new 59 cases as travellers returned from overseas. The cases jumped from 210 to 269 in the past 24 hours, according to the media reports here.

Queensland's total number of confirmed cases stood at 94.

State Premier Annastacia Palaszczuk said it is now "a different world" from just last week.

For Victoria, the Premier Daniel Andrew said the government could also ban gatherings of fewer than 100 people, noting he could not rule out further changes.

Chief Health Officer Brett Sutton said the spike in cases has been due to people who have travelled overseas.

Sutton said that the transmission in Victoria was not because of community transition like Italy.

Sutton has continued to urge people to wash their hands, socially distance and stay home if they are unwell.

"These are critical measures to be applied regardless of the 100 and 500 threshold,” he said.

In Western Australia, Health Minister Roger Cook said four new coronavirus cases have been confirmed overnight, taking the State's total to 35.

McGowan also condemned panic buyers in supermarkets as "jerks, drongos and bloody idiots."

He said there was "plenty of food to go round" and no need for people to buy in excessive quantities.

The outbreak, which first emerged in China's Wuhan city last year, has marched across the globe, infecting 198,006 people and killing 7,948, according to a tracker maintained by the Johns Hopkins University.

Italian researchers have claimed that they have successfully developed a vaccine to contain coronavirus (COVID-19) which is likely to work on humans, a report said.

Luigi Aurisicchio, CEO of Takis, the firm developing the medication, said that a coronavirus candidate vaccine has neutralised the virus in human cells for the first time, the Arab News reported.

"This is the most advanced stage of testing of a candidate vaccine created in Italy. Human tests are expected after this summer," Aurisicchio was quoted as saying to Italian news agency ANSA.

"According to the Spallanzani Hospital, as far as we know we are the first in the world so far to have demonstrated neutralisation of the coronavirus by a vaccine. We expect this to happen in humans too," he added.

The researchers experimented with the vaccine on mice that had successfully developed antibodies that blocked the virus from infecting the cells. They further observed that the five vaccine candidates generated a large number of antibodies, and selected two with the best results.

All of the vaccine candidates currently being developed are based on the genetic material of DNA protein "spike", the molecular tip used by the coronavirus to enter human cells.

They are injected with the so-called "electroporation" technique, which consists of an intramuscular injection followed by a brief electrical impulse, helping the vaccine break into the cells and activating the immune system, the report said.

Researchers believe that this makes their vaccine particularly effective for generating functional antibodies against the "spike" protein, in particular in the lung cells, which are the most vulnerable to coronavirus.

"We are working hard for a vaccine coming from Italian research, with an all-Italian and innovative technology, tested in Italy and made available to everyone," Aurisicchio was quoted by the Arab News report.

"In order to reach this goal, we need the support of national and international institutions and partners who may help us speed up the process," he noted.

The total number of COVID-19 infections, fatalities and recoveries since the pandemic began has risen to 213,013 in the country.

Hubei, Feb 10: The death toll in the deadly coronavirus outbreak in China and other parts of the world has reached 904, CNN reported citing Chinese authorities on Monday.

The number of infected people globally has now hit the 40,000 mark.

According to the country's health officials, the number of people, who died from coronavirus in the Hubei Province, has risen to 871.

"As of 24:00 on February 9, Hubei Province reported a total of 29,631 cases of new coronavirus pneumonia, including 16,902 cases in Wuhan. 22,160 patients are still being treated in hospitals. 73,127 people remain under medical observation," read the statement from the Chinese Regional Health Committee.

The novel coronavirus was first detected in China's Wuhan city in late December and has since spread to more than 25 countries.

On Sunday, the new coronavirus even surpassed the fatalities caused by the SARS epidemic in 2003.

The World Health Organisation (WHO) has declared a global health emergency in the wake of the outbreak.

Meanwhile, WHO's international expert mission led by Dr Bruce Aylward embarked for China.
