Is this why it feels like everyone keeps getting COVID?

What"s That Rash? ·

2023/06/27

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

What makes a COVID superspreader?

2023/06/20

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.

What could a diabetes drug do for long COVID?

2023/06/13

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

Tegan has been playing away, making another show.It's called Quick Smart, and because you're such a loyal Coronacast listener, we'll give you a preview here. If you like it, please find the Quick Smart feed and subscribe! This first ep is about something weird that's happened in the last 12 months or so - the fact that all your friends - and perhaps you as well - have ADHD now.So where did this ADHD spike come from? Just how big is the gap between people seeking treatment and those able to give it

We're in a wave - are more drugs the answer?

What"s That Rash? ·

2023/06/06

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

Wait ... how many people have long COVID?

What"s That Rash? ·

2023/05/30

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?

Is there a new flu surge?

2023/05/16

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. It could even be described as a surge. So what's going on? Why are we being attacked by COVID, flu and RSV all at once?Also on today's show:* Remember that time a stranger made Norman stick something up his nose in an abandoned dungeon? * What's going on in China now that they've dropped COVID restrictions?

WHO's given up on COVID?

2023/05/09

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?

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

Not again! A new wave is building, so what now?

2023/03/14

Another wave of COVID infections seems to be underway in parts of Australia, and NSW is leading the pack. The variant soup is getting more complex by the day — but luckily the dominant mutations don't seem to be causing more severe disease. 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?References: Almost 20,000 excess deaths for 2022 in AustraliaOne-Year Adverse Outcomes Among US

Do antivirals increase your risk of rebound COVID?

What"s That Rash? ·

2023/02/21

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.

2023/02/14

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.

How well does getting COVID protect you from COVID?

What"s That Rash? ·

2023/02/07

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.

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.
