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.
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!)
There is no rationale. Everyone must be tested on arrival and if Aust air crew go home they must take an antigen test at airport and be given a home test fit developed by Aust company being utilsed in USA (why not here 🤷🏻♀️).
We wrote on 7 December, before this outbreak, to State and Federal ministry about holes in the handling of international travellers and glight crew & how to ameliorate them. It is not the community’s fault.
Screening is different to diagnosis. Accuracy for screening rapid tests differs marginally across test kits approved for Aust use. Passengers & crew screening needs high negative test accuracy & most rapid tests have 98.8%-100% accuracy.
Could be performed. Accuracy differs marginally across test kits approved for Aust use. Because you are looking for certainty that passengers & crew are not infected the test needs to have high negative test accuracy and most rapid tests have 98.8%-100% accuracy.
My colleagues & I wrote an open letter last week calling for rapid testing. The virus doesn’t understand exemption rules. Everyone without exception must have a rapid antigen test for covid on arrival - everyone, no exemptions. thenewdaily.com.au/news/2020…
