if all 18 cases today are genetically linked (and not travellers in hotels) then total=150; average in red zone (11).

no so its assumed everyone (without contraindications) should be tested as immunity from natural infection may last 8months or even less.

vaccines don't ringfence until it reaches herd immunity because vaccines dont (yet) stop symptom fess infection and transmission by vaccinated persons). Herd immunity for COVID is yet undetermined but assumed to be greater than 80%.

I'm not suggesting we cant do this. You misinterpret my tweet. We need all hands on deck - not chasing cases.

There is a weekly surveillance report that gives within 24, 48 and 72hr of tests reported but tricky to find (I just looked and couldnt find it). Ask NSW because your questions are important.

Vaccinating 80% of Australia in 8 months means 170,000 injections per day every day; 4 times the average daily number Covid tests (Apr-Dec). Our health system will struggle to vaccinate while fighting outbreaks unless quarantine flaws are strengthened before March.

Only silence. I now hear third hand Qantas crew will have a rapid saliva trst. Still silence on immediate testing of travellers or daily testing quarantine staff

My colleagues and I wrote 7 Dec an open letter to State/Fed asking for rapid antigen testing of every incoming travellers without exception. Better late than never.

Of course. What im saying is its a planning error not complacency (community was going about their lives in zero case load). This is all due to holes in the handling of incoming international flights quarantine system.

I’ve been talking about this in the media since March. Dec 7 we decided we needed to go directly to government.

98.8-100% accuracy for negative result. A little lower for pos result. In other words better at labeling you neg & means more confidence letting you go to a cold Quarantine Hotel or letting Aust flight isolate at home (currently with no test!) & hotel letting staff go home.

We wrote this on December 7 before this outbreak - still not response. Outbreak management is building up rings of defence with strategies that are never perfect hence the multiple rings. Add rapid testing at airport to close a hole in our defence.

Sadly our letter was written on Dec 7 to ministries before the outbreak- still no reply. A CMO dismissed our idea in press saying neg test today can be pos tomorrow was not accurate antigen test is accurate in early stages, with higher certainty than what we have now (nothing!)
