some crazy metrics; the +ve testing rate in NSW is 27%! (90k tests, 23k positive yesterday). It's a bit skewed because the advice has changed from 'get tested if you sniffle' to 'get tested only if work is making you and you feel sick'. But still, extrapolate that if you will...
Also, a medical professionals definition of 'mild symptoms' doesn't mean sitting at home with a sniffle watching tv. It means sitting in hospital hooked up to beepers vs being knocked out with tubes in you. So you still take up a bed, doctors/nurses time, an ambulance ride, triage thru emergency etc etc
i went into emergency a few weeks back on a weekday morning because i thought i'd broken my hand again (it wasn't thankfully), but i spent longer waiting to get admitted/xrayed than i did when I had broken my hand during full covid shutdown (and that was on a weekend afternoon + i needed a cast etc)
