I don't follow the figures closely but I can see they are something of a mish-mash that raise more questions than provide answers.
To give out national figures on cases prefixed by the words "could be" should not be taken as gospel. The virus is in all kinds of different infection stages in different parts of the country, we have no sign of it here yet are preparing for a zombie apocalypse to come up the valley!

I fear the virus may still have some surprises in store, the one thing that does keep recurring is how little we understand about it. It could get be harder to beat than we think.
