The numbers are now going up alarmingly and if the exponential growth continues we will be up to our worst peak by Christmas,
So what caused it?
A lot of the increase in infections happened in very late August (since numbers went up by specimen date around 1st September, and you don't test positive for 5 or more days), so I'm not sure the increase in R is down to schools reopening.
But it could have caused by people returning from holiday?
What do people think?
