Wed, 02 Aug 2023 - 13min - 1451 - COVID's not alone in the wastewater
In the early days of COVID, we used wastewater surveillance to spot undetected community transmission. Our sewage gave public health authorities early alerts that COVID was spreading. Wastewater surveillance also gives information on sub variants: what's on the rise and what's in decline. But there's other stuff in wastewater - and it's downright criminal. That's captured on today's rather smelly Coronacast.

A lot has been said about COVID antivirals, especially on how they might help bring down the number of deaths from the disease. But occasionally an interesting phenomenon occurs: a patient takes the antiviral drugs, feels better, only to come down with COVID again. So how do COVID antivirals work and why does the rebound sometimes happen?

It's the depths of winter, and every second person you know has a cold of some sort. Most are mild but some can hit hard - as we all know from COVID and influenza. But what about the third virus in the unholy trinity of winter bugs? RSV, or respiratory syncytial virus, is tracking a lot higher than usual for this time of year. Who's most at risk, how can you protect yourself, and how much do the numbers have to do with increased testing overall? Oh, and what does "syncytial" even mean?

Wed, 05 Jul 2023 - 09min - 1447 - Is this why it feels like everyone keeps getting COVID?
Our immune system does an amazing job keeping us healthy - but it works in mysterious ways, especially when it comes into contact with novel viruses like SARS-CoV-2. We've talked a bit before about imprinting - the concept where the first time your immune system sees a virus can determine how it'll react to that virus in the future. And a recent study in the prestigious journal Science has found the Omicron variant could be taking advantage of that - possibly showing why people seem to be getting repeat Omicron infections. So what could this mean for public vaccination strategy and our risk of reinfection?
Wed, 28 Jun 2023 - 13min - 1446 - What makes a COVID superspreader?
We've all heard that COVID spreads in clusters and sometimes the cluster comes from a single person who can infect nearly everyone around them. They're superspreaders and it's been opaque how much virus a superspreader is actually responsible for spreading around. Now a study has found that in a group of deliberately infected people, just two of them were responsible for nearly 90 percent of all the virus emitted - even though they only had mild symptoms.
Wed, 21 Jun 2023 - 12min - 1445 - What could a diabetes drug do for long COVID?
Sometimes a study comes along that shows some amazing results and one published in The Lancet does just that. The study - which looked at people aged between 30 and 85 who were overweight or had obesity - has found a "globally available, low-cost, and safe" diabetes drug called metformin could drastically reduce the instances of long COVID by 40 per cent. Sadly they didn't find the same results with ivermectin (and they looked). So what could be going on? How could this old drug be so good at what it's doing? And how could this drug be used to help bring down long COVID cases? That's on this week's Coronacast - along with a clarification of NSW hospital data and antiviral prescriptions.

The public health measures we relied on in years past to control COVID have now largely gone. Social distancing is no more and there aren't nearly as many masks around as there once was and we're grossly under-immunised. So what about antivirals?

Wed, 07 Jun 2023 - 13min - 1442 - Wait ... how many people have long COVID?
Long COVID has nearly been around as long as COVID itself. It wasn't long after the pandemic began before we started hearing about long haulers - people who were suffering from the virus long after testing negative. But even today, we still don't know the precise definitions of what exactly long COVID is and how many people suffer from it. But we are getting closer to a clearer picture. So why is it important to know?

As respiratory disease goes, COVID got us good. But it's important we don't forget the old school ones like flu and RSV. There's quite a bit of flu around at the moment too.

With the World Health Organisation (WHO) announcing that COVID-19 is no longer a "global health emergency", you'd be forgiven for thinking the pandemic's over. But alas, it isn't. According to WHO, the "emergency" phase is over but COVID will remain a persistent threat for a lot longer, saying the disease is still killing someone every three minutes. So how can COVID no longer be an emergency, but also remain so deadly?
Wed, 10 May 2023 - 12min - 1438 - Arcturus' rise: Another COVID (sub sub sub) variant!
The Omicron variant has been spinning off all sorts of sub variants during its 17 month long reign. The latest is XBB.1.16 - known also as Arcturus - and like its sibling sub variants doesn't seem to be all that different. But while Arcturus is busy trying to become the most popular sub variant of the month, we are undergoing another wave of infections. There are hundreds of people in hospitals around the country and it's continuing to affect how the health system operates. Also on the show: Is COVID going to the dogs?

Another wave of COVID infections seems to be underway in parts of Australia, and NSW is leading the pack.

Regardless, as more people get infected and re-infected, researchers are fast at work trying to determine what might protect people from long-term consequences.

In 2022, Australia saw an estimated 12% increase in the number of deaths compared to expert predictions. More than half of those were due to COVID-19. And there are signs that even the deaths that couldn't be directly linked to COVID-19 are a result of the pandemic. This pattern isn't just playing out in Australia, but around the globe. So what are the driving factors, and what can be done to address them?

Wed, 01 Mar 2023 - 1432 - Do antivirals increase your risk of rebound COVID?
Antivirals are an important measure to prevent severe disease in vulnerable people with COVID-19. But there have been concerns antivirals could lead to rebound infections — the resurgence of viral load following the completion of the medication. So what do the latest studies say?

An old debate has been reignited after a review declared the effects of masks is uncertain and in need of further investigation.

Australian adults will be able to get a fifth dose of the COVID-19 vaccine within a fortnight. People aged 18 and over who've not had a COVID vaccine or a positive case in the last six months will also be eligible for another shot.
Wed, 08 Feb 2023 - 1429 - How well does getting COVID protect you from COVID?
The majority of Australians have received at least two doses of a COVID vaccine — and they've most likely caught the virus as well. New research suggests this hybrid immunity offers good protection against severe disease, although the risk of long COVID persists with even mild bouts of infection. There could soon be a simple model to predict how likely you are to recover well from COVID, or whether you'll go on to develop post-viral symptoms.

Wed, 08 Feb 2023 - 1428 - Three years on, is COVID still an emergency? Or should we be more worried about the flu?
It has been three years since the World Health Organization declared COVID-19 a global health emergency. The WHO isn't ready to downgrade the status of the pandemic, but the committee has agreed we're at a 'transition' point. Meanwhile an outbreak of influenza in mink has highlighted the need for greater animal-human disease surveillance.
Wed, 01 Feb 2023 - 1427 - We're back! So what did we miss?
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?
Wed, 25 Jan 2023 - 1426 - 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.
Wed, 21 Dec 2022 - 1425 - Are we going to be free of this wave by Christmas?
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.
Wed, 14 Dec 2022 - 12min - 1424 - How do you know if a pandemic is from a lab leak?
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 wave away the possibility.
Wed, 07 Dec 2022 - 1423 - Is this the end of China's COVID zero?
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 end of China's COVID zero?

Wed, 30 Nov 2022 - 1422 - Are the waves getting smaller?
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 it better to have a quick one, or one that lasts for a longer time?
Wed, 23 Nov 2022 - 10min - 1421 - Ok, now it's off and running - how do we slow it down?
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 and fast?
Wed, 16 Nov 2022 - 13min - 1420 - Does anyone give a rat about RATs anymore?
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 anymore? And why is it important that the tests do as they say?
Wed, 09 Nov 2022 - 14min - 1419 - Has the next wave already begun?
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?
Wed, 02 Nov 2022 - 12min - 1418 - What could the floods mean for disease outbreak?
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?
Wed, 26 Oct 2022 - 12min - 1417 - Australia's COVID report card is in. How did we do?
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?
Wed, 19 Oct 2022 - 11min - 1416 - New Omicron booster is here! How well will it work?
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?
Wed, 12 Oct 2022 - 13min - 1415 - What could the end to mandatory isolation mean?
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?
Wed, 05 Oct 2022 - 12min - 1414 - Putin isn't our only worry from Russia
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 Cororonacast. Also on today's show: * Tracking new COVID variants: we look at 2.75.2

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 up.

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 finally ending the pandemic?
Wed, 07 Sep 2022 - 11min - 1410 - Is it time to scrap COVID isolation?
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 still useful? * Moderna sues Pfizer/BioNTech * Didn't I see Norman out and about without a mask on the other day?
Wed, 31 Aug 2022 - 11min - 1409 - The best news since January - but can it last?
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?
