While the number of new coronavirus cases in Melbourne continues to fall, for many it's not falling fast enough.

The average number of daily cases is edging down day by day, but there's a long way to go until it meets the hurdle to take the big step out of lockdown.

So why are cases falling so slowly and what needs to happen next to get cases down?

On today's show:

* As numbers drop why don't we see a faster fall in the tail?

* How long can a person be asymptomatic? Does it just disappear? Can they become asymptomatic again?

* My husband and I are chronic asthmatics and take a preventer. Would good asthma management assist us if we caught COVID-19?

* Would there have been less antibiotic use this year and how beneficial might that be?

And it's Quick Fire Friday:

* What episode number are we up to?

* Is Norman's towel ready and waiting?

* Is there more chance of catching coronavirus from getting on a plane or sitting inside for a meeting/lecture? Or are they the same?

* Do you have any thoughts as to what the minimum age for vaccination might be?

* What's the risk of spread of coronavirus on children's play equipment?
