What's That Rash?

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?

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?

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?

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?

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?

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?

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 DeltacronThe 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

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

The sixth season of If You're Listening tells the story of Australia's turbulent history with climate change, and what that means for the future.As we approach a federal election where climate and energy is a key battleground, this eight episode series will examine how Australia wasted decades fighting change, instead of capitalising on it.This is a special listen of the first episode and is the only time it'll appear in the Coronacast feed, so if you want to check it out search for "Australia, If You're Listening" where ever you get your podcasts.Or find the links here on the ABC website: https://www.abc.net.au/radio/programs/if-youre-listening/

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

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!

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 diseaseAlso 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?

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

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.While people can once again travel, WA is in the middle of a growing outbreak - but it has imposed restrictions to help flatten the curve.With WA now open again, Australia is once again whole - so how is the nation tracking for COVID and how does 2022 compare to previous years?Also on today's show:* The TGA provisionally approves AstraZeneca's combination antibodies. What is it? How does it differ from vaccination? And why might it be useful?

Last year was all about the push to vaccinate adults and teens against COVID-19, and despite a slow start we certainly got there in the end.Now this year the vaccine focus has turned to two things: third doses for adults, and first doses for younger kids. So how is the vaccine rollout for 5-11s going? How do the vaccines work in kids and what is the latest of safety and efficacy?

Throughout history, war and disease have gone hand in hand.As the Russian/Ukrainian war escalates, it's still too early to know what effect it'll have on the COVID-19 pandemic but it certainly won't help.So what can we learn from previous conflicts and pandemics, like the 1918 flu pandemic or even the plague?That's on today's CoronacastAlso on today's show:* What can we learn from two Omicron superspreading events in Newcastle?* Cases in WA continue to go up* Quick(ish) Fire Friday returns!

More and more states and territories are slowly removing restrictions, and letting people try to return to a sense of a normal life.Victoria yesterday said that masks can come off in most indoor environments from midnight Friday and Queensland is scrapping density limits and stopping daily press conferences.So is this finally the end of the pandemic, or more just a lull between variants?Also on today's show:* Vaccination while pregnant safe, another study finds* Worried about long-COVID? Here are four possible risk factors that might trigger it.

As we move to the next phases of the pandemic, there are many people who are yet to make the psychological jump and mental readjustment to a different life.Many are only mildly anxious, but there are also groups of people who are still worried about leaving their house.So what can you do if you have a friend or family member suffering from pandemic related anxiety or even depression?GUEST:Professor Frances Kay-Lambkin, a psychologist and mental health researcher at the University of Newcastle

It's taken several weeks, but the number of new COVID-19 cases in Western Australia is now increasing rapidly.At the start of February, WA had a 7-day average of 19 cases a day. Now that average is nearly 100.So from here, can we expect to see a very rapid increase in cases like we saw in the eastern states over Christmas/New Year? Or could the delayed reopening and closed borders help flatten that curve?Also on today's show:* Victoria and NSW announce they're loosening restrictions even more

So, where's this pandemic actually heading? It's a good question and quite hard to answer as... well... no one can tell you the future.But experts have never shied away from making some educated guesses, including SAGE, the Scientific Advisory Group for Emergencies in the UK.They've published four scenarios ranging from as good as it can be given the circumstances to downright doom and gloom.So on today's Coronacast, what does SAGE think we can expect from the pandemic over the next few years and which scenario is most likely to be right?

When COVID burst onto the scene in late 2019, it came as a shock to most of the world's population and we've all been dealing with it ever since.But to many researchers, it was less of a surprise and more of an inevitability - and now they're urging governments to act now to stop the next one.It comes down to the old medical saying: prevention is better than cure.So what can be done to help prevent the next pandemic and how much will it cost?

For months now, experts have been saying we'll need three doses to be protected from coronavirus, especially the Omicron variant. And now, it's official.Yesterday, the rules changed and people over 16 will be required to have all three doses of a COVID vaccine to be considered "up to date". So why make the change now when previously two vaccines were considered good enough? And might it mean for vaccine mandates down the track?Also on today's show:* Should me and my family just go out and get Omicron? * Should I wait the full eight weeks to get my daughters second vaccination or should I do it at six?* Does testing positive just after my booster reduce its effectiveness?

Two years into the pandemic, we're still discovering new things about COVID almost daily.The latest is what COVID can do to your heart, a year after you've been infected. A huge study has shown really disturbing problems from heart attacks, to strokes, to blood clots on the lungs to heart failure. So on today's Coronacast, who is at most risk? And what does this tell us about COVID as a disease?Also on today's show:* International tourists - what will they bring?* The real story about aged care* Who needs a fourth dose, when and why?

When it comes to ways to fight COVID-19, vaccines have been the main tool we've used so far during the pandemic.But new antivirals are being produced for use including in Australia which has recently provisionally approved two different drugs.They promise to help stop at-risk people ending up in hospital and dying.So what are the drugs, how do they work and will they usher in a new way of handling the pandemic?GUEST:Professor Josh Davis, Infectious Diseases, Uni Newcastle, past president of the Australasian Society for Infectious Diseases and member of the National COVID-19 Clinical Evidence Taskforce

As the Omicron wave continues to subside, there's the temptation to hope that now that it's over, the whole pandemic is done.And while we can dream that it's true, hoping unfortunately won't help that become reality.The general weariness is understandable for us everyday people, but what about for policy makers and their preparations for new variants or the next wave?Also on today's show:* Are we really at Omicron's peak?* Can a person be infected simultaneously with two or more strains of coronavirus?* Why aren't COVID case numbers exploding in WA?* Will Novavax be offered as a booster?* Can you be asymptomatic and get long COVID? Could this explain why I am so tired?

Looking at the family tree of coronavirus is a bit like taking a trip down memory lane.The whole crew is there including the famous ones like Alpha, Beta and Delta, and the ones that never really made it into the big time.But what if we zoom in on Omicron? Lately, there's been a bit of noise made about a few Omicron sub variants. What are they? And how much should we worry?Also on today's show:* TGA releases a post-market review for rapid antigen tests. What can we learn from it?References:https://www.tga.gov.au/post-market-review-antigen-and-rapid-antigen-tests

As the scary peaks in all states and territories in Australia, except WA, seems to be behind us, there is now a new sense of calm.Daily coronavirus cases seem to be falling for now, and there's renewed hope that the worst of this wave is behind us.And according to some experts, it could well be the case both here and globally. Due to so many people now either infected by Omicron or vaccinated, they say we may be settling into a new trough of equilibrium.So is it the end of the pandemic? Or just a calm before the next storm? Also on this week's show:* Deaths are still high* WA cases are increasing. What are their options? * Vaccines help protect against long COVID

The number of people dying from COVID hit a record high this week, as large case numbers continue in most states and territories.It comes as no surprise then that NSW and Victoria announced that people can get their third dose at the three month mark, bringing it forward from the 31st January which was originally planned.So why roll out boosters even earlier? Could the number of deaths be tied to people not being as protected as they could be? Also on this week's show:* Vaccine supply and logistics* Novavax approved!* Is the term "elective surgery" a bad way of phrasing it?* Peaks? Coming soon?* How reliable are rapid antigen tests?* Kids vaccination, kids going back to school and keeping kids safe

We're all no doubt very tired of the pandemic by now and could be forgiven for hoping now that Omicron has landed in Australia, once we get over the current outbreak it's all over.But according to evolutionary virologist Eddie Holmes, sadly Omicron won't be the last and in fact the next variant probably won't evolve from Omicron.So what can we do apart from get vaccinated and hope this terrible roller coaster ride will somehow end soon?

Well, that escalated quickly.When Coronacast left you last year, there were nearly 4000 national daily cases. Yesterday, there were more than 72,000 and there's no sign it's slowing down.Health systems in most states and territories are beginning to groan under significant pressure.Add to it probably more than one or two hundred thousand cases a day going unreported, it's fair to say COVID in Australia is in a bit of a mess.So on today's Coronacast - which will be coming out weekly for at least the next few weeks - when might the peak be here? And what can we expect in coming days and weeks?

It's been a massive year for coronavirus and COVID-19. There have been outbreaks, lockdowns and a pile of new variants.But there have also been massive successes like the vast majority of Australians coming forward to be vaccinated.But sadly, the pandemic seems like it's far from over. So on today's last Coronacast of the year, we look forward to 2022 and offer some tips on how to stay safe this summer.We'll be back around February 2022! Thanks so much for listening and writing this year.

As COVID numbers continue to rapidly increase in NSW - likely due to the Omicron variant - we're being warned that modelling is pointing to 25,000 cases a day by the end of January.Yesterday, NSW Health Minister Brad Hazzard talked about modelling by the University of NSW which said case numbers could reach heights not seen before in Australia.And it comes as NSW continues to let its foot off the restrictions brake, redefining what a close contact is.So is what is happening there likely to happen everywhere else in the country Omicron has found its way into?Also on today's show:* A very special guest!

There was a large jump in COVID cases in NSW yesterday, and while we're largely moving on from day to day case numbers - this one is worth talking about.Why? Well, there's a new variant in town and health authorities are already suggesting that we can expect far more from Omicron in coming weeks.The same goes for other states and territories - like Victoria which still has higher daily figures than NSW, but hasn't yet seen a big jump.So on today's Coronacast what should we make of the rising caseload and does it matter?Also on today's show:* A deeper look at what's going on in South Africa* An announcement on Coronacast for 2022!

After nearly two years of constant internal border changes, by the end of this week large parts of Australia will once again be open for domestic travel.South Australia opened a few weeks ago, Queensland opened yesterday and Tasmania is due to open tomorrow. Western Australia has also finally given a date and will reopen on the 5th of February next year.So with state and territory bubbles bursting all over the place, what might come next for people who live there?Also on today's show:* How is decoupling going?* Fourth dose anyone?* Pregnancy and booster shots

Australia now has two different booster options to choose from when the inevitable time comes for the third dose of coronavirus vaccine.Moderna was approved by the country's vaccine expert group ATAGI over the weekend.We'll also be able to get the booster a month earlier, with the Government announcing a shorter period due to the threat of waning immunity and new variants.So if Moderna is a choice, should you take it over Pfizer? Does it even matter? And why is the Moderna booster only a half shot?Also on today's show:* A preprint study has found that Astra seems to wane faster than other vaccines, leaving no protective effect against symptomatic disease from Omicron 15 weeks after the second dose. What could this mean for the country's booster campaign?

As the data from initial studies into how Omicron evades our immunity continue to flow in, it's becoming more and more likely that a third dose - or booster - is going to be essential.Several more studies have been released, all showing large falls in immunity to the Omicron variant.One thing that the studies imply though is that there are much higher antibody levels in people who have either been infected, or received a third dose.So how much will third doses be needed to combat Omicron?Also on today's show: Quick Fire Friday! (booster edition)

One of the first studies into Omicron and immunity has reported back and it's not super great news: there's significant evasion of antibodies produced by the Pfizer vaccine.But not all is lost. The study says that the Omicron variant uses the same way of getting into our cells, meaning our existing tools and techniques should be relatively easy to change so they work better. The study is not yet published, and is a very small sample size so it's worth keeping in mind that this is still a very new area of science and is subject to change.Nonetheless, as today's Coronacast explains, it does give us a glimpse of what is likely to come.Also on today's show:* Could a mozzie vaccinate someone by biting a vaxed person and then an unvaxed person?* Your booster experiences

Beyond the nasty and sometimes life-threatening symptoms that COVID can bring, there's another risk: long COVID. It's the collection of prolonged symptoms including brain fog, smell loss and fatigue.And while we know that being vaccinated drastically reduces your risk of a bad bout of COVID itself, a lingering question has been whether it also protects you from long COVID. Well, according to a yet to be peer reviewed study, the answer is yes it does. Also on today's show:* Is there any research work being done to modify the virus to develop a relatively benign but transmissible COVID variant which could be released to "crowd out" the current dangerous variants? * Is there a chance that Omicron is different enough that instead of replacing Delta, you get both if not together then one after another?* And we're after your stories about getting third-doses. Was it easy? Or hard?

Over the next several months, the fight between Delta and Omicron is going to be scientifically fascinating.In the red corner is the current world champion Delta, which easily beat out every other variant of concern to date.In the blue corner is the challenger Omicron, whose continued existence probably relies on its ability to beat out the champion.But how will we know who's winning and when will we get a better sense of it all?Also on today's show:* What makes a virus go viral?* Who decides which variants you make vaccines for?* What happens if Omicron turns up in a place with no Delta (like Queensland or Tasmania, for example)?

It's been a bit more than a week since we learned of Omicron, the newest coronavirus variant of concern.And while we're still a while from knowing solid answers, the world's scientists have done an amazing job over the last 7 days unraveling parts of Omicron's mysteries.The three big questions are will our vaccines continue to work? For people who do get the virus, will it be severe and will it beat Delta to become the coronavirus champion of the world?So on today's Coronacast, what we know from the latest science about answering those big questions.Also on today's show* Does it escape previous immunity and/or our vaccines?* Is it better at spreading than Delta?* Does it matter? Does it make you sicker than previous variants?* Where's Dr Norman Swan's Omicronometer of Panic heading?

Just like we're likely going to be stuck with COVID for the rest of our lives, we're probably also going to be stuck wondering which is the most effective vaccine to protect against it.Well lucky we've got science to help sort it out, with a new study putting the Moderna and Pfizer vaccines head-to-head across hundreds of thousands of people.And other scientists have been busy working out how much protection you have against reinfection, if you are infected in the first place.Also on today's show:* Quick Fire Friday* Tegan interrupts Quick Fire Friday with her own - excellent - Quick Fire Question.

As the days tick by since Omicron was discovered, it's slowly spreading around the world.One example is reports of a couple of Israeli doctors who likely picked up Omicron in the United Kingdom, before flying back home.Their symptoms are said to be mild at the moment, but more worryingly, both of the doctors were fully vaccinated with Pfizer - that's all three doses.So what do we know about how Omicron works with our current vaccines? Also on today's show:* If we have been vaccinated to recognise the spike protein, why are variants so concerning? Is it the spike that changes?

Nearly two years into the global coronavirus pandemic, it's probably safe to say that we're all pretty much ready for it to be done.So no wonder we're hoping that very early reports from South Africa are possibly, just maybe, indicating that the Omicron variant is "milder" than variants before.But how much evidence is there for that yet? Is it true, or just wishful thinking?Also on today's show:* Is it possible that the emergence of this variant is actually an encouraging development for the COVID pandemic?* No big changes yet for Australia's international borders* The Omicron variant mutation that might end up helping us (a bit)* In previous episodes you have mentioned that variants can "out compete" other variants. What exactly does this mean and what is the mechanism behind it?* An update to the Dr Norman Swan Omicronometer of Panic

As the world desperately awaits news from scientists on anything Omicron, some experts have started thinking about where the variant might have come from.One theory is that it's from someone severely immunocompromised, where the virus has had millions of opportunities to evolve against a poor immune response.But it's far from the only theory.So on today's Coronacast, a few other possibilities of where - and when - Omicron might have popped into existence.Also on today's show:* The evolutionary lineage of Omicron* How should Australia be preparing?* The Dr Norman Swan Omicronometer of Panic is born

It's the news we didn't want: There's a new variant of concern in town and it's got all sorts of mutations just where you don't want them.It's also got a new fancy name: Omicron, and it's reportedly outpacing Delta in countries in southern Africa.But is it really? Is it more infectious? Is it more virulent? Is it vaccine resistant, and if so by how much? How much do we really know at the moment? Should I panic?Also on today's show:* What if the Omicron variant is the sort epidemiologists expected to see earlier in the pandemic: highly transmissible and less virulent?

As pandemics go, the coronavirus one is pretty big. It rapidly spread around the world, and is still causing problems.But how does it compare to past pandemics? Are we actually living in a fortunate time in human history?If we could magically replace COVID with a bug from the past, would it be a good or bad idea? Would you prefer the plague? Syphilis? Perhaps a flu pandemic might tickle your fancy.Well to help you decide, on today's Coronacast, we go through the pandemics in history.Also on today's show:* Rapid antigen tests work well against Delta* Quick Fire Friday!

All around the country at the moment are family discussions and debates about what to do about that one relative or friend who still doesn't want to get vaccinated.The numbers of double vaccinated people continue to rise as people realise it's in their benefit to get the jab.But there will always be holdouts, no matter what policies are put in place.So how much does it matter if someone at the Christmas party is unvaccinated when nearly 90 percent of us 12 or older are double dosed?Also on today's show:* How careful should my vaccinated pregnant daughter be about where she goes and who she sees?* What's the latest science on viral loads?

When the slew of variants popped into existence last year, scientists began worrying what it could mean for vaccine resistant variants down the line.So far, the Delta variant has remained top dog. While it is much more infectious than the original coronavirus, thankfully it doesn't evade our vaccines by much.But what about down the line? As more and more of the world is vaccinated, will the virus find a way to evolve to get around vaccines? That’s on today’s Coronacast.Also on today’s show:* Lockdowns return to Europe* How is Japan doing such a good job?* What side effects can I expect from my Pfizer booster shot if I had AstraZeneca for my first and second shot?

As we start to reopen to the world, it's inevitable that we'll start to see more cases of COVID-19 travel over our international and domestic borders.But it's far from the only bug that will make the journey while travelling inside a human.Influenza is one viruses we've been largely protected from over the last 18 months, after international border closures put a halt to incoming flights.So on today's Coronacast, what do we have to keep in mind when reopening and can we protect ourselves and our kids against virus we haven't seen in quite a while.Also on today's show:* Will a third dose give me better protection against variants? * Is there any evidence that taking paracetamol or ibuprofen after vaccination would reduce the body's immune response?

It's become a common claim among people who are still COVID-19 vaccine hesitant, that they say they're "waiting for Novavax".While there are currently three safe and effective vaccines available in Australia, Novavax is still not approved for use.Australia ordered Novavax a year ago, but as yet there's still no sign of it and the TGA says its application for approval is still under evaluation.So on today's Coronacast, if someone says they're waiting for Novavax, here's what you might want to reply with.Also on today's show:* Is it best to have Astra as my third shot?* We want to hear from you! Please fill in our listener survey and tell us what you think of the show.
