Health NerdVerified account @GidMKReplying to @AndrewHayen @drlucydeng and 3 othersYes, from the preprint it appears that the confidence interval includes 0% prevalence. Also, the sample is very biased (elective surgery admissions), so I'm not sure whether the inference to the entire population makes sense1 reply 0 retweets 7 likes

They did correct for the specificity but state on retest only 5 strongly positive (5/2991 = 0.17% with CI that includes 0%). So agree we can say Aus rate is low but be wary of extrapolating from 5 non-random cases in NSW/VIC to the whole of Australia. pic.twitter.com/FywFoRdyIK
