So can someone explain to me why the self isolation period is 10 days then?
If they can spread it for 10 days why only ping people who have come into contact with them in the last two?
Am I getting the wrong end of the stick here or is the government really stupid?
first thought - with bucket loads of Cases but very few actual Patients....they're concerned about folk questioning that they're being "pinged" with absolutly zero sign of an illness - and what does that reveal - exactly what they dont want to reveal / or become obvious....its all about the False Positive rate (FPR = Uninfected) vs the False Negative rate (FNR = Infected)....and so, if prevelance is low - they can't escape it....False Positive it is, hence the loosening of the chains.
