@MeBigbrain @pepsi_man @matty @sickburnbro no, they didn't say that the 1 out of 1000 that actually had it tested positive, they said he had the disease, if there was an real positive in their sample, 1/1000 prevalence does not guarantee that your group of 1000 has somebody who actually has it, there was no mention of the false negative rate, so, you cannot confidently say 51 positives, it could be 50 false positives and possibly 1 false negative.
