Victoria has hit a road bump on its pathway to reopening, recording 15 new cases of coronavirus yesterday as it tries to suppress a new outbreak.

The Chadstone cluster has continued to grow, and has spread to a regional town about 60km from Melbourne.

It comes as the state's Chief Health Officer has revealed that Melbourne's second wave appears to have focused on larger families.

So why are households with more than six people at the centre of this outbreak?

On today's show:

* How has an outbreak happened in Melbourne when it's supposed to be still under restrictions?

* In NSW, why were there so many cases yesterday in hotel quarantine?

* How significant is the risk that the steroid that President Trump is taking can lead to euphoria and affect his sense of well being?

* Norman has mentioned treating people on their stomachs a few times lately, what does he mean by that?

With each new day, we're learning a little bit more about the US President's battle with COVID-19.

Yesterday, doctors said the president's oxygen level had dropped a couple of times and that he had been put on a steroid drug used in the most severe of COVID cases.

So what could his treatment of experimental drugs and now steroids tell us about President Trump's condition?

On today's show:

* What is going on with President Trump's treatment?

* If he's not that sick what could the steroid dexamethasone do instead?

* What's happening in Victoria and New South Wales?

Also Norman discusses the UK reset on expectations about who'll get a vaccine first, and chats about a study showing that maybe obesity isn't such a risk factor when it comes to COVID.

By now you've probably heard the news that the most powerful man on the planet has tested positive for coronavirus.

US President Donald Trump is part of a growing cluster of cases popping up in the White House, Republican Senators and the Republican National Committee.

How did it happen? And what will Trump's course of treatment mean for the rest of his coronavirus journey?

One of the main tools in our belt to fight coronavirus is contact tracing.

That is, when you identify someone who is positive for COVID-19, you isolate them and then try and find out all the people they've come in contact with.

The way we do contact tracing in Australia hasn't changed much since the beginning of the pandemic, but in other parts of the world it has.

So on today's Coronacast, are we doing contact tracing the wrong way and what can we learn from countries like Japan?

As the number of COVID cases continues to drop in Australia, there's suddenly a whole lot more talk again about travel bubbles and increasing international arrivals from "safe" coronavirus countries.

The Prime Minister Scott Morrison is talking up an idea to let travellers from countries where there are low caseloads do their 14 days quarantine at home rather than in a hotel.

While mismanagement of the hotel quarantine system in Victoria led to a large outbreak, in other states and territories it has protected the country.

So how could we safely reopen international borders?

Also on today's show:

* What's the latest with healthcare worker statistics in Victoria?

* My husband is still convinced that flu has a higher mortality rate than COVID-19

* Is there any news on how successful or not the Russian vaccine has been?

And Norman has some interesting research about cats and dogs and if they can get coronavirus.
