$1 billion health fund to assist states with coronavirus

Prime Minister Scott Morrison has announced a joint COVID-19 public health response, with 50-50 cost-sharing between the Commonwealth and the states.

He says the standalone arrangement, separate from other hospital funding agreements, will be driven by demand.

"The Commonwealth, on executing those agreements, will immediately put $100 million down as an advance through the normal distribution mechanism to the states, to ensure that they are in a position to immediately meet those costs," he said.

"But we are estimating based on the advice that we have at the moment this could be as much as about $1 billion — $500 million each — that we would have to be allowing for.

"I hope it is not that much, it could be more, but we at least have to enter into these arrangements having some sense of the scale of what we're dealing with here."

It will cover costs incurred since January 21.

A bad day on the ASX

The local share market experienced heavy losses on Friday.

The ASX 200 dropped by 2.8 per cent to 6,216 points by close, wiping out all Thursday's solid gains.

Travel stocks are among the hardest hit, with Qantas and Flight Centre both down.

We also got the latest retail figures, with the latest report from January worse than expected.

While sales were not hurt by the coronavirus at the beginning of this year, experts are expecting the epidemic to dent sales in the coming months.

Helicopter sent to drop test kits on cruise ship

A cruise ship in the United States has been ordered to stay back from the Californian coast until passengers and crew can be tested. Officials say about 3,500 people are aboard, including four Australians.

The test kits are actually being lowered by a helicopter onto the Grand Princess by rope as the vessel lay at anchor off the coast of San Francisco. Authorities said the results would be available on Friday.

It comes after a traveller from a previous voyage died of the disease and at least four others became infected. Princess Cruise Lines said fewer than 100 people aboard this recent cruise ship had been identified for testing.

Businesses forced to close across the country

The list of businesses, schools and other establishments that have been forced to send people home and shut the doors is growing by the day.

Already we have seen Vodafone, Cisco, Clayton Utz and Epping Boys High School among the shops and schools to close due to fears of a coronavirus contamination.

Authorities have been eager to stress that essential services will function as per usual, even if staff are forced into quarantine.

Edith Cowan University disaster and emergency response Associate Professor Erin Smith says it is almost certain more businesses will close in the coming days and weeks, but that the short-term pain will likely prove to be worth it.

"We just need to see it as a practical and logical way to stop the spread of the disease," she said.

"Look at it as saying, 'yes, it's a little bit of an inconvenience for us in the short term, but they're practical measures that we may need to take to try to blunt that spread of disease'."

How will coronavirus impact the broader economy?

Economist Tim Harcourt, who specialises in international trade and labour economic issues in the Asia-Pacific region, told ABC Radio that even before the coronavirus crisis hit we were already seeing a slowdown in global trade.

"I think trade was already under some pressure, but this has probably brought it more to a quicker pace than expected," he said.

So far Mr Harcourt said the industries most affected by coronavirus were the tourism industry and offshore manufacturing.

"I think a lot of imported manufactured goods — toys, pharmaceuticals, some IT goods — will probably be slower but not held up totally," he said.

Meanwhile, unions are urging the Government to address the potential plight of casuals who may get caught up in coronavirus quarantine.

"There are two problems. Number one [being] the impact on them and their families if they lose hours because of this virus," secretary of the Australian Council of Trade Unions Sally McManus said in a video posted to Twitter.

"And number two they shouldn't have to go to work if they're sick, if they're showing symptoms, they should be able to stay at home like everyone else."

On Thursday morning, Treasurer Josh Frydenberg said the Government was doing everything it could to keep businesses operating and people in jobs, flagging a stimulus package would be worth billions.

Make sure to check your travel insurance policies

Travellers who purchased insurance policies before the coronavirus outbreak are finding they may not be covered for virus-related costs.

Consumer group Choice has warned many insurers don't provide cover for pandemics or epidemics.

But Jodi Bird from Choice says "cancel-for-any-reason" policies may provide some protection.

"It is the only policy available that will allow you to cancel, so it's likely to be pricey," he said.

"It will only cover up to 75 per cent of costs and there's a few other conditions. The other important thing to bear in mind is that it doesn't cover medical expenses."

Why are nearly 10 per cent of Iran's leaders infected with coronavirus?

As our Middle East correspondent Eric Tlozek explains, when the coronavirus outbreak began, Iran's leaders refused to implement quarantines, saying it was a practice from the Stone Age.

Now 23 members of Iran's parliament and other senior advisers have tested positive, while a 71-year-old advisor to Supreme Leader Ayatollah Ali Khamenei has died. And those same officials who scoffed at quarantine have quarantined themselves.

In fact, the situation has caused so much anger in Iran that Holly Dagres, an analyst with the Atlantic Council, told the ABC it has sparked speculation that coronavirus could be the final crisis to trigger a regime collapse.

"It's really hard to say that would be an outcome, but right now the situation is looking dire for the Iranian Government and it really heavily relies on how it handles the coronavirus outbreak."

Vietnamese health delivers 'banger' to tackle COVID-19

The Australian Government is working hard to tackle coronavirus with travel bans and health measures and the United States Senate just approved a multi-billon-dollar package to combat the virus.

But in Vietnam health authorities have found a different way to take on coronavirus.

They have released a pop song that has gone viral to educate their citizens about how to tackle the coronavirus.

Pop singers Erik and Min feature in an animated video that has had more than 4.5 million views since its launch late in February.

The song tells citizens that the virus's hometown "is Wuhan".

Some other lyrics from the song, which John Oliver, the host of HBO's Last Week Tonight called "a banger", include:

"Let's wash our hands, rub, rub, rub them" and "fight back against corona" as the chorus.

Could you get infected with two strains of coronavirus?

Probably not.

A new research paper claimed the new coronavirus has two distinct strains — and that it's possible to be infected with both at the same time — but some experts are unconvinced.

The study by 12 researchers in China, which has been accepted by the National Science Review, looked at 103 genomes of SARS-CoV-2 and found the virus had evolved into two separate strains, known as "S" and "L".

The "S" type is older and seems to be milder, while the newer, more prevalent "L" type is more aggressive.

The study also looked at the evolution of SARS-CoV-2 and other related coronaviruses in an attempt to figure out which animal the virus evolved through before it got to humans.

In contrast, other experts in the field say the two types the Chinese researchers claimed to have identified were a result of both normal viral mutation and errors in data that they were relying on.

"[The differences] are sequence errors which in fact were corrected very soon after they were originally uploaded to the GISAID database," Professor Ian Mackay from the University of Queensland said.

He said the patterns they identified were no more than normal variation.

"They're almost all identical. It's like us putting on different clothes from day to day," Professor Mackay said.

How can the Government avoid a coronavirus recession?

A Government stimulus package of some description is beginning to take shape, and will likely come in two phases — the first targeting affected sectors, the second targeting households.

Economists say some individuals, particularly pensioners and the unemployed, may receive direct payments of some kind, but we shouldn't expect a "Rudd-style" cash splash for everyone.

Grattan Institute economist Danielle Wood says there could be other measures aimed at households, such as lifting the Newstart allowance.

"You hit the most disadvantaged section of households and you know they go out and spend, and there's a good case for doing that anyway," she said.
