keyword here is confirmed. Many of us carry the virus and are untested (or "unconfirmed") so that 5% number is likely to massively decrease to around 0.5% at some point if (second keyword), governments decide to implement large scale testing.
But if you also would consider that without the lockdown the number would have been worse you need to adjust the numbers to reflect a larger infection rate and a collapsed health care where everyone with complication is dead.
I am going with train of thought were tested and confirmed were tested because they had high chance of getting virus. You don't test people who had no chance of getting a virus so I don't think those numbers are that much higher.
Second thing is that testing already was increased in a lot of places but last 2 days new cases number did not grow it stayed around the same.
