- 1480 - A single glass of red wine for your health, yeah or nah?
Much has been said about the single glass of red wine. It's good for you, it’s bad for you, it's good for you again. It can be confusing to follow. Norman and Tegan take on this age-old health question — does a single glass of red wine have health boosting benefits?

As the weather cools down, you may be noticing more people around you are dropping from cold or flu. And with COVID-19 also in the mix, it’s understandable that many are wondering how they can boost their immunity to avoid getting sick so often.

Kate Middleton announced via a video message that she is undergoing treatment for cancer. The Princess of Wales has been out of the public eye since Christmas. This is the first official announcement about her condition since she revealed she would be undergoing planned abdominal surgery in January. So what What do we know about Kate's cancer diagnosis?

Did you know that we're evolutionarily predisposed to seek out sweet treats? Simple carbs were harder to come by in caveman times than they are today. Now, the consensus is we all need to cut down our sugar intake. One way people are doing that is by replacing their sucrose with non-sugar sweeteners.

Mon, 04 Mar 2024 - 01min - 1469 - Are hormones hindering your workout?
Have you ever been told to 'listen to your body' when it comes to fitness? It makes sense. You shouldn't push through injury, or past the point of exhaustion. But how far is too far? There are now dozens of apps and hundreds of advice columns on how best to 'listen to your body'. One strategy that's rising in the ranks is adjusting your workout routine to work alongside your menstrual cycle.

Wherever you look, viruses are going into and coming out of animals. Mostly this happens without much fanfare, though occasionally it causes big problems.

If you think that excavating your nose is a harmless if somewhat disgusting habit - think again. A new study reckons you could emerge with COVID-19.

We've said it before and we'll say it again - make sure you get your booster dose. But what, you ask, is in it for me? How likely am I to be the one who dodges severe disease? Well a new study has quantified this. It's a number familiar to epidemiologists - the number needed to treat to prevent a certain outcome.

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?
Wed, 19 Jul 2023 - 12min - 1449 - What's RSV again? The *other* winter virus that's hitting hard
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.

Sun, 11 Jun 2023 - 11min - 1443 - We're in a wave - are more drugs the answer?
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? Could making them more available to more people be a way to reduce the amount of severe disease and limit the waves of COVID? Watch us on YouTube: https://www.youtube.com/watch?v=gE7At1S7tho

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?

The Omicron variant has been spinning off all sorts of sub variants during its 17 month long reign.

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

Wed, 15 Mar 2023 - 1434 - Almost 20,000 more deaths than expected last year – is it all down to COVID?
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, 08 Mar 2023 - 1433 - We're all getting boosters – why aren't little kids?
Since ATAGI updated its booster advice there have been lots of questions about why kids aren't able to get another jab. We discuss the reasoning behind the age limit, as well as some other vaccine-related questions from listeners. Also, a few controversial COVID topics... from Ivermectin to the US Energy Department's theory on where the virus came from.

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? Also, we speak to an expert informing the parliamentary inquiry into long COVID about how to best care for patients.

Wed, 22 Feb 2023 - 1431 - Don't chuck out your mask — and when to get boosted
An old debate has been reignited after a review declared the effects of masks is uncertain and in need of further investigation. Meanwhile Sydney scientists have found a receptor that sticks to the coronavirus and pulls it away from lung cells, opening up potential treatment avenues. But for now, vaccines remain the best protection against severe disease. So when should you get your next booster? We answer some common questions. References: Physical interventions to interrupt or reduce the spread of respiratory viruses Yes, masks reduce the risk of spreading COVID, despite a review saying they don't Fibroblast-expressed LRRC15 is a receptor for SARS-CoV-2 spike and controls antiviral and antifibrotic transcriptional programs
Wed, 15 Feb 2023 - 1430 - BONUS: ATAGI updates its booster advice — it's not just about the fifth dose
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
Wed, 28 Sep 2022 - 1413 - COVID numbers just got a whole lot harder to interpret
One of the mainstays over the past few years has been daily reporting of COVID cases, hospitalisations, ICUs and deaths.
Wed, 21 Sep 2022 - 1412 - How else has COVID been killing people? Taking another look at excess deaths.
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.
Wed, 14 Sep 2022 - 11min - 1411 - Where’s my Omicron specific booster? And will it help?
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?
Wed, 24 Aug 2022 - 13min - 1408 - How much coronavirus is coming out of your mouth?
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?
Wed, 17 Aug 2022 - 13min - 1407 - Can we wave bye bye to the B5 wave?
Is it finally time to say a big see ya later to the latest B5 COVID wave? The Omicron family has already brought us several waves - the first at the start of the year when it muscled out Delta and the most recent big one via B5. But there are signs that it is finally slowing down. Cases are dropping and there are small, but positive, signs that deaths are also falling. So while it may be the end of the worst of B5, what could be next?
Wed, 10 Aug 2022 - 10min - 1406 - Rebound? Reinfection? Release me from this pandemic prison!
As more and more people become infected with COVID-19, more and more people are also going to be reinfected. But there's another type of reinfection known as a rebound infection, which can happen in the days after you've recovered. The US President Joe Biden tested positive again this week for COVID-19 only a few days after he was cleared following his treatment with antiviral medication Paxlovid. So what could be going on? How common are rebound infections and could it extend to people who don't take the drugs also being reinfected?
Wed, 03 Aug 2022 - 12min - 1405 - Do we need a new health revolution?
When the pandemic started we were so worried about surfaces. But it turned out that wasn't so much of a concern. The big thing was the very air we breathe. But as Governments largely scale back on mandates and restrictions, experts are urging more be done on things that can prevent spread of the virus And the big target is better ventilation. On today's special Coronacast, Tegan Taylor takes a look around to see how bad the air is in everyday life.
Mon, 01 Aug 2022 - 12min - 1404 - Why BA5 isn't like measles, but is still a big worry
BA5 sure is making itself well known, and is responsible for soaring infection and reinfection rates right across the country. So how does it compare in infectiousness to other diseases? Well working that out is a difficult question. It's partly down to changing variables like vaccination and controls, but also changes to the virus itself. So on this week's Coronacast, why it doesn't really matter if BA5 is as infectious as measles - it's still doing a lot of damage. Also on today's show: * Enough about BA5 - what about BA2.75? Bring on the 'Centaurus' talk! * An update on pregnancy and COVID-19 * And BA5 in schools - will a booster help? cvp_20220727_episode477_ba5_infectious.mp3 13286016 830000
Wed, 27 Jul 2022 - 13min - 1403 - The Doctor is back. What's Australia's COVID prognosis?
It's been a month since Coronacast took a break, and since then a lot has changed. The BA4 and 5 variants have become dominant, and immunologists are starting to worry about the state of play. Firstly, BA4 and 5 are acting a bit like new variants. They're evading vaccines and prior infections even more than original Omicron and there's no sign they're slowing down. And secondly, COVID case loads are surging and hospitals are feeling the pressure. So what else has changed over the last month, and what's the rest of winter looking like? Also on today's show: * I'm suddenly eligible for a fourth dose. Do I bother getting it? * Can you get the 2nd booster shot 28 days after having COVID (in line with information that re-infection can occur after 28 days), or is it still best to wait the 3 months, and if so, why is it best to wait? * I've had two AstraZeneca and one Moderna shots. What should I have as my fourth dose?
Wed, 20 Jul 2022 - 12min - 1402 - The latest great news for young kids and COVID!
There's been a bunch of good news this week about kids and COVID, including kids under 5 moving a touch closer to become eligible for vaccination A Scandanavian study has shown that before babies are born, they get an immune benefit from their vaccinated mother. Another study has looked at a rare condition that can happen in kids after COVID, called MIS-C, and found vaccinated kids are way more protected from it And also both Pfizer and Moderna have moved slightly closer to being registered for kids under 5 in the USA. Also on today's show: * Are there rapid tests available to test for influenza? * I've noticed that cases seem to be falling. Is it just that it's being under reported? I haven't heard any mention of it in the media but it's the opposite of what I expected as we head into winter. AND WE'LL BE TAKING A BREAK FOR THE NEXT MONTH BECAUSE NORMAN IS ON HOLIDAYS. SO KEEP AN EYE ON THE FEED AND WE'LL BE BACK SOON.
Wed, 15 Jun 2022 - 11min - 1401 - Have we lost our vaccine mojo?
This time last year, Australia's vaccination program was getting underway and many were coming forward for their first or second shots. But Australia's haven't embraced the third dose as quickly or in as large numbers. The third dose is vital for the best protection against disease, and is recommended for the majority of Australians. So why aren't people coming forward as quickly? Also on today's show: * Is it possible that we may have caught COVID without realising it? * Are there instances of assumed second COVID infections that are actually just relapses?
Wed, 08 Jun 2022 - 11min - 1400 - Which subvariant will be the One True Omicron?
Since the variant we now know as Omicron burst onto the scene late last year, it's proved to be a shapeshifter, spawning no fewer than five subvariants so far. Each have their own characteristics, but which is the most likely to become the dominant strain? There's finally enough data around to start making a comparison - so which subvariant will rule them all, what features give it the advantage, and what possible tools we might use to fight it? Also on today's show: * If I'm triple vaccinated and COVID is everywhere, could I have encountered it and fought it off, making me even more immune now? * What's the latest on the scary, mysterious hepatitis that's been reported in kids?
Wed, 01 Jun 2022 - 10min - 1399 - How worried should we be about monkeypox?
While COVID continues to ravage the world, it's far from the only virus that's affecting humans at the moment. Cases of flu are soaring in Australia, and the Queensland Government is worried enough about it that it's offering all Queenslanders a free flu vaccination. And to add to that is a new outbreak of monkeypox in Europe and North America with 100 suspected and confirmed cases so far, though cases have not been severe. So what is Monkeypox, could it end up like COVID and how worried should we be?
Wed, 25 May 2022 - 10min - 1398 - The BIG COVID challenge facing Australia’s next government
We are only days away from the 2022 Federal Election, where we'll find out who'll be leading the country for the next few years. But for whoever wins, there's the huge reality of dealing with and managing the ongoing COVID pandemic, which is still killing an average of 40 Australians a day. COVID policy and response hasn't featured much during the election campaign. So on today's Coronacast, what COVID issues will face whoever wins office next? Also on today's show: * Our daughter tested positive on a RAT. We had a PCR test the same day and it came back negative. So we tested again via a RAT and it was positive again. Does this mean the PCR test wasn't done properly? * I have been diagnosed with COVID twice this year. Is this the future, COVID every 4 or 5 months?
Wed, 18 May 2022 - 10min - 1397 - Yes, you can get long COVID if you're triple vaxxed
A British COVID report has finally answered a question many have had: can you get long COVID, even after you're triple vaccinated. And the answer is, sadly, yes. About eight to nine percent of people have some sort of long-COVID symptoms, even after they've had their third dose. But there is some good news: long COVID is still far lower in vaccinated people than in unvaccinated. Also on today's show: * What's happening with second generation vaccines? * How worried should we really be about surface transmission?
Wed, 11 May 2022 - 10min - 1396 - 5000 deaths this year and counting
While most of the Australian population is vaccinated against COVID-19, going by the amount of people who have died in 2022, this is by far the worst year of the pandemic. More than 5000 people have died so far this year, and another 30 or 40 are continuing to die on average each day at the moment. So on this week’s Coronacast, why have we stopped paying attention to deaths and can we do anything to reduce them? Also on today’s show: * Paxlovid is now part of the PBS. So what is the drug again? Who should take it? When? And why?
Wed, 04 May 2022 - 10min - 1395 - The sub-variants just keep coming
When Omicron burst onto the scene late last year, scientists were shocked at how many mutations it had compared to previous variants. We now know that it's way more transmissible than previous variants and less nasty than Delta, although that hasn't stopped it from causing a lot of severe disease and death. But biology isn't static and Omicron has continued to evolve. First came BA1, then came a new wave of BA2 and now we're starting to see another new subvariant: BA4. So on today's Coronacast, what is BA4, where did it come from and how much of a worry is it? Also on today's show: * What's going on with the hepatitis condition in kids? Is it being caused by COVID-19?
Wed, 27 Apr 2022 - 13min - 1394 - How long can any country stay COVID zero?
China is fighting its largest coronavirus outbreak since the pandemic begun, but the lockdown being used to try and control it is facing resistance? Videos on social media appear to show small riots breaking out in parts of Shanghai while some residents are recording themselves screaming and yelling from their apartments in desperation. So is China's zero-COVID policy unable to withstand the onslaught of Omicron? And why is China resorting to lockdowns? Also on today's show: * How's COVID going in the USA? * Omicron refresher: Do RATs work against it? What are the main symptoms? How long is the incubation? * How much of the world has had COVID now?
Wed, 13 Apr 2022 - 10min - 1393 - Our first proper flu AND covid season looms
The race has well and truly been on for third dose COVID-19 vaccinations, but now add to that vaccination for the coming flu season. The past couple of years have seen a lull in flu infections because closed borders kept more than just COVID out — but that will change this year. So what happens if you get both COVID-19 and the flu and the same time? Is it even possible? And how do you reduce the risk of that happening? Also on today's show: * Why isn't Australia pulling its weight when it comes to reporting on vaccine effectiveness?
Wed, 06 Apr 2022 - 11min - 1392 - When two variants become one
As the BA2 subvariant of Omicron infects its way to the top of the coronavirus leaderboard, we're thanking our lucky stars that it's not as or more severe than Delta. But imagine a coronavirus variant that has genes from both Omicron and Delta: enter Deltacron The ability for two variants to combine and share genetic information is possible, and according to recent research has already happened. So what's the possibility the next variant of concern will not be due to mutation, but instead combining? Also on today's show: * Antibody profile after Omicron * What makes something a subvariant and not just a new variant? * Lots of questions about fourth doses
Wed, 30 Mar 2022 - 11min - 1391 - Wasn't the peak meant to be in January?
With cases rising quickly again, it's left many wondering: wasn't the peak supposed to be behind us? Well, turns out the pandemic isn't over and a mix of relaxed restrictions and the BA2 sub-variant have combined to once again push up infections. It also shows that the rollercoaster ride that we're on may not be stopping for a while, and the up and down nature is something we'll have to get used to. Also on today's show: * Increase in diabetes with long COVID * More on if we're going to need a 4th dose

Sun, 20 Mar 2022 - 34min - 1389 - What will winter bring as the sibling of Omicron rises?
The sub-variant of Omicron, known at the moment as BA2, is being blamed for a rise in cases in NSW and likely in other states and territories. And overseas, Hong Kong is struggling with a wave which is killing more and more people due to low levels of vaccination in high risk age groups. So what could the sub-variant mean for Australia as the weather slowly cools down and we enter darker, cooler times? Also on today's show: * China goes into lockdown in several big cities * Australian researchers have uncovered resistance mutations to Sotrovimab
Wed, 16 Mar 2022 - 10min - 1388 - How many people had COVID before me?
Occasionally, Coronacast gets a question from the audience that not only stumps them, it stumps the expert scientists as well. And this week, that question came from Helen who was wondering how many people before her had COVID and passed it on to someone else, stretching all the way from her back to Wuhan in China. It raises many interesting questions about viral evolution and how we can reduce the number of infections globally. Also on today's show: * BA2 Omicron sub-variant becoming more and more dominant, according to NSW Health Minister Brad Hazzard * Coronacast will be dropping back to weekly. We'll be out every Wednesday so watch your feed!
Fri, 11 Mar 2022 - 10min - 1387 - What's COVID doing to your brain?
A study has found that COVID is associated with changes to the human brain in some people after they've been infected. The study, published in the journal Nature, has found brain related abnormalities in patients six months or so after their initial infection. The findings suggest this can happen regardless of severity but may be worse in those with severe disease Also on today's show: * My wife and I are in isolation at the moment after both testing positive to COVID. Her symptoms are worse than mine and she suggested I isolate in a different part of the home? * The virus in my body is a direct descendant of the virus that infected people in the wet market in Wuhan. How many people do you think it has been through to get to me? * If there is every chance we will all, eventually get Omicron, is there an argument to getting it sooner than later?
Wed, 09 Mar 2022 - 11min - 1386 - Rethinking the lab escape theory
Did COVID escape from a lab? Was it natural evolution? How did it happen? These are all very big questions that scientists have been working on answering ever since SARS-CoV-2 arrived in our lives in late 2019. Now, the release of two (still to be peer reviewed) articles have outlined more evidence that COVID didn't escape a lab, and instead evolved naturally in animals before jumping to humans. And on today's Coronacast, they may have even found the very cage in the Wuhan market where COVID made the jump. GUEST: Professor Eddie Holmes, Sydney Medical School, University of Sydney
Mon, 07 Mar 2022 - 13min - 1385 - Australia is one again! So how are we tracking?
Western Australia has reopened its border after more than a year of staying shut off from the world as part of its COVID control strategy.
