While the number of new daily coronavirus cases in Australia is now mostly in single digits, there's still occasional cases of unknown origin popping up.

It's also known as community transmission, and it's when health authorities get a positive test for COVID-19, but can't work out where the patient picked it up.

So is this something we're just going to have to get used to? And what does it mean for phrases like eradication, elimination and suppression?

On today's show:

* What does eradication, elimination and suppression mean? And what’s the difference?

* What does the term 'routine testing' mean?

* How safe is it to play in a clarinet or flute ensemble even with social distancing?

* Norman has mentioned diarrhoea as a COVID-19 symptom but it is never mentioned as a symptom that warrants testing. How often is diarrhoea a symptom of COVID-19?

And Norman has some research about US poison control, which found a huge jump in the people being exposed to cleaning products and disinfectants since coronavirus hit. So is this all Donald Trump's fault? You might be surprised.
