It's certainly taken a turn for the worse in Sydney, with the number of COVID-19 cases per day doubling over the last four to five days.

We've heard that it's going to get worse before it gets better, and there are forecasts of more than a hundred cases today.

So how much longer are we in the upward trajectory of this curve? When will numbers finally start to come back down? And how long, realistically, are we looking at with this lockdown?

* How do we know if the vaccines will have long term effects or not?

* Will COVID-19 become a disease of the young?
