What's That Rash?

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.

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?
