South Australia has spent its first night under increased restrictions as the state battles a coronavirus cluster that increased dramatically in size yesterday.

From when the first case was discovered on Saturday, the number quickly jumped to double figures by Monday as authorities conducted contact tracing and testing.

So far, the cluster is primarily centred around a single family with a link to an Adelaide hotel quarantine facility.

But on today's Coronacast, the big question remains: when did the virus manage to escape and what could that mean for South Australia's chances of getting it under control?

On today's show:

* What went wrong in hotel quarantine?

* Is it time to mandate mask wearing in SA?

* What is Norman's view on testing workers in medi-hotels?

* Do you think the black death would have been easier to handle than COVID-19 if the people back then had the resources we do now?
