We're back! So what did we miss?

2023/01/24

Although we didn't begin this year with any lockdowns or border closures, the pandemic hasn't abated.In fact we're off to a worse start than we had in 2022. Australia surpassed 1,000 deaths a whole week earlier than it did last year. New subvariants are circulating fast. So what's changed? What's the best protection? And could sluggish surveillance be leaving us vulnerable?

What has COVID cost us in 2022?

What a year 2022 has been for COVID. We started with a new variant sweeping the world, heavy restrictions and border closures and we end with very few restrictions remaining.We also sadly end with millions not fully vaccinated, and an aged care system that is still battling the virus.So on the last Coronacast of the year, we go down the 2022 rabbit hole and try to make some predictions for 2023.

Are we going to be free of this wave by Christmas?

2022/12/13

The number of new weekly COVID cases seems to be slowing, but sadly doesn't seem to be slowing fast enough to be free of the current wave by Christmas.Last year was a strong COVID Christmas, as the Omicron variant took over from Delta bringing thousands and thousands of new cases.This time, the wave will be smaller - but still noticeable.And we break down the big announcements from National Cabinet: PCR testing and the country's COVID strategy in 2023.

How do you know if a pandemic is from a lab leak?

What"s That Rash? ·

2022/12/06

There's been a lot of discussion about the origins of COVID, especially on the question of did it come from a lab, did it form naturally - or maybe a mix of both.Well a new book called Dark Winter has tackled this question and has come to the conclusion that we better get better at identifying outbreaks - because sometimes they're intentional.While there's no direct evidence that COVID came from a lab leak, author and Professor Raina MacIntyre argues it is possible and some have been too quick to

Is this the end of China's COVID zero?

2022/11/29

Protests are breaking out across parts of China in response to the Chinese government zero COVID restrictions.The number of COVID cases has soared in China in recent weeks, rising at a similar rate to what happened in March this year.The outbreak was quickly brought under control, by the use of the Government's severe measures such as forced external quarantine and city wide lockdowns.But with widespread discontent and protests, it may prove harder to keep this outbreak under control. So is this the

2022/11/22

There's hope that the current Omicron sub variant wave will be in decline again just in time for Christmas - but like everything COVID, it's hard to know for sure.Both case loads and hospitalisations due to COVID have continued to increase in the last week.The latest advice from state health authorities say that overseas experience suggests the current wave might pass relatively quickly, though they warn local conditions may mean it's different here.So what do we know about the latest wave? And is

Ok, now it's off and running - how do we slow it down?

2022/11/15

Another week, another big jump in COVID case numbers and rising admissions to hospitals.The next wave is well and truly underway, with the BA4 and BA5 sub variants rapidly being replaced by versions that are even more immune evasive.However, when Omicron turned up last year there were a variety of public health measures in place to try and slow infection rates. This time though, we've only got vaccination and an optional sense of public duty.So can we slow down the next wave, or is it coming in hard

Does anyone give a rat about RATs anymore?

What"s That Rash? ·

2022/11/08

Rapid-antigen tests promised so much: a quick, cheap and easy way to tell if you were COVID positive so you could make a decision to help protect yourself, family and community.But in reality, it's far more complicated. The tests were initially hard to come by, expensive for some and the rollout was patchy.And now, add to that the fact that the coronavirus has continued to evolve - making it hard to tell if RATs can even detect COVID.So on this week's Coronacast, should we give a rat about RATs

Has the next wave already begun?

What"s That Rash? ·

2022/11/01

New sub-variants of Coronavirus are increasingly appearing in Government statistics and clinical breakdowns of the virus' spread.The BQ1 and XBB sub-variants of Omicron have surged overseas, and are also starting to pick up in Australia.It's likely that they'll take over the BA5 subvariant that's been dominant for the past several months.So what could these new variants bring and given they're likely to evade our immune systems, what could it mean for spread and severe disease?

What could the floods mean for disease outbreak?

2022/10/25

For those keeping count, 2022 hasn't been a great year for animal virus outbreaks into human populations.A new study has suggested that the Omicron variant may have had a reservoir in mice.Also, there are warnings that the East Coast floods may see a rise in people infected with the Japanese encephalitis virus, and parts of Uganda are locked down to prevent an Ebola outbreak from spreading into cities and across borders.So what's going on and how can we make sense of it all?

Australia's COVID report card is in. How did we do?

2022/10/18

After all big events, it's important to look back and think about what worked and what didn't.And one of the biggest events lately is COVID, and especially how Australia handled it.A group of researchers and experts have done just that, analyzing everything from the vaccine rollout to virus control measures to looking at what could be improved for the next pandemic.So what did we do well, and what could we have done better?

New Omicron booster is here! How well will it work?

What"s That Rash? ·

2022/10/11

The first COVID booster that targets the Omicron variant has finally been introduced to Australia's vaccine rollout.The vaccine from Moderna targets the BA.1 Omicron subvariant, but that's no longer the dominant strain.Omicron has continued to evolve since the vaccine was updated, and the dominant strain is now BA5.So how well will the new vaccine work with BA5? And if you've already had 4 doses, why can't you get this one as your 5th?

What could the end to mandatory isolation mean?

What"s That Rash? ·

2022/10/04

The decision by National Cabinet to remove mandatory isolation for people testing positive to COVID-19 is seen by many as an "official" end to the pandemic.The period had already been reduced from two weeks to one week to 5 days, but soon it'll be gone entirely.It's one of the final public health controls that remained to try and slow the spread of the virus, and some experts say it'll lead to problems down the road.So for how long should we treat COVID differently?

Russia has been in the news for all the wrong reasons, and here's another concern to add to the list.Scientists are on the alert about the risk of another virus spilling over from animals to humans. This time it's Russian horseshoe bats and a coronavirus from the SARS family.It's known as Khosta 2 and while there has been no known human transmission so far, unlike Khosta 1 scientists say there is the possibility that it could occur.And it's not affected by vaccines for COVID-19.That's on this week's

When COVID hit, there were a whole lot of predictions about how many people would die.Not just of the virus itself, but the knock on effects from reduced care and other diseases.One of the latest attempts at working out the number of excess deaths is recently published and has taken a wide view of the population looking for trends.And while the group found that excess deaths from undiagnosed COVID is likely low in Australia, increased deaths from COVID-caused complications is beginning to show

Where's my Omicron specific booster? And will it help?

2022/09/06

It may not be long before Omicron specific vaccines are available in Australia, like they are elsewhere in the world.Last week the Therapeutic Goods Administration provisionally approved an Omicron variant specific vaccine, but we’re still waiting on ATAGI to recommend its use.So with it likely to be available soon, is it worth waiting for if you’re due for your booster or should you just get what’s available now?Also on today’s show:* Snot and the inner parts of your nose - could this be the key to

Is it time to scrap COVID isolation?

What"s That Rash? ·

2022/08/30

Back at the start of the pandemic, if you tested positive for COVID - or even if you were a contact - you were looking at two weeks of isolation. These days, that's been downgraded to a week, and contacts are generally free to go about their normal life. But while COVID is still undeniably a health risk, having masses of people undergoing mandatory isolation takes its own toll. So should compulsory isolation be shortened or even scrapped altogether?Also on today's show:* Are vaccination requirements

It seems that COVID cases in the latest wave have indeed peaked, and all things across the usual pandemic metrics are improving.It's the best COVID caseload we've had since Omicron came into our lives late last year.So has BA5 burnt itself out or is this just a small respite? And are we due for another variant?Also on today's show:* How is COVID associated with increased risks of neurological and psychiatric conditions?* Is monkeypox getting away from us?

How much coronavirus is coming out of your mouth?

2022/08/16

Pretty much ever since the pandemic began, we've been told to socially distance by at least 1.5 meters if possible to reduce the chances of infection.But as the science is gathered on how much viral load flows from an infected person, how relevant is that recommendation? Was it even correct in the first place?Well a new - yet to be peer reviewed - study has attempted to explain just how much virus is in one's exhaled breath aerosols.And what does this mean for how the virus is spread?
