Surely as a layman you can at least read into it that more testing = more cases?
What I would rather see is cases not being used at all. Whether that use is for the layman to try and determine the current or future state that we are in or the inevitable media frenzy in using large case figures to whip up fear.
There could be 25,000 cases identified tomorrow but only 0.5% of those end up being hospitalised. On Tuesday there could be 18,000 cases but 2.2% of those end up being hospitalised. I cannot really see how anything can be reliably read into them to help predict a future trend other than making a wild guess, that's exactly what they seem to be doing.
And this is before we can dissect what should be determined a 'case' or not!
As a layman, I agree that more measurements taken will equate to a greater proportion of positive results, assuming that testing coverage is incomplete.
I don’t accept the extension of that argument that counting cases is a bad thing. The statistics are very incomplete at present, and we should welcome greater precision in those figures.
We would probably agree, however, that the conclusions to be drawn from current statistics are necessarily tentative, and a simple comparison of today against, say, 6 months ago will not be meaningful. I suspect we would then disagree on whether they should then be used to try to set policy - my view being that prediction is better than waiting to be surprised.
