NSW is on the verge of a major winter outbreak. They are making the mistake that Victoria made last year by expecting people to "change their behavior."As a positive, most of the 13 were already isolating.
But yes, the time of the year and general slackness in NSW could easily see Sydney and/or NSW cutoff from the rest of the nation like Vic was in July - Sept 2020...
In my view - there have been two specific errors in NSW so far:
1) Should have had a precautionary lockdown when the 1st case was dicovered. IMHO this should be standard practice - top get contact tracing ahead of it. (Same should have occurred in Melb, then the mystery link to Wollert Man might have been found, or at least stopped from speading it). Ha that happened in NSW, we wouldn't have had someone wandering around Westfield infecting people.
2) After the Westfield event was identified, AT LEAST everyone who'd been there put in isolation (ie all the staff, and hence al lthe businesses shut for 2 weeks). There was clear evidence of fleeting transmission to at least 3 other people, and there are staff there who've had it, and continued working. We only know of the people who've subsequently become symptomatic for every 3 who are symptomatic there are 2 who are just as infected and just as infectious who are not symptomatic.
Pretty much all of the transmission events that occurred since the Westfield event was discovered could have been prevented. Yet there has been a seeding event in the Illawarra, where someone infected people in an Obstetritcian's waiting room, and someone travel to Wellington NZ while infectious.
NSW has *almost* got to the sort of restrictions required to contain it - were they implemented last week.
NSW is now making the mistake of attempting a "proportionate" response, which means creeping into an ever lengthening lockdown. If people aren't whinging about it (ie it actually changes people's behaviour before the risk to them becomes tangible), then it's too slow.
