What makes Melbourne's outbreak hot or not?

The Holiday Inn cluster in Melbourne has continued to grow, with close contacts yesterday testing positive to COVID and more exposure sites being added to the growing list.

So far, 11 people are connected to the outbreak which started in a Melbourne hotel quarantine facility before being spread to workers and another resident.

Other states are keenly looking on – deciding if they should once again throw up border closures and restrictions.

But the next moves will all depend on how hot the hotspot in Melbourne is. So on today’s Coronacast, what makes an outbreak hot or not?

Also on today’s show:

* How big of a pinch of salt should we be taking the WHO investigation in China?

* Chief Medical Officer Paul Kelly says the Astra vaccine will very shortly receive TGA approval

* Why didn’t SARS-CoV-1 not blow out to the proportion like the current SARS-CoV-2?
