thanks for taking us through these things; nice to have the madness of PCR testing woven into what some recognise as more standard methods; and more measured ways; deep in the WHO of the past, must have been some sense and tradition; before they were bought out by big money;
so much education for us here: sensitivity and specificity; though we have heard them many times, good to go back and remind ourselves how they are defined; and the things that lead from them: the sort of puzzles folks set; the incidence of a disease is .. z%; sensitivity is x%; specificity is y%; if the test comes back positive, what is the chance the person truly has the disease? .. that sort of brain teaser ..... could almost just be a short but very educative post ....... best wishes as always for allowing us the privilege of being part of such an wonderfully immersive and endlessly educational and refreshing experience; best wishes again
The second sentence "Snow remarks that cholera is transmitted from the healthy to the sick over and over again." I assume this is a typo and should be transmitted "from sick to the healthy". Thanks for all the great work.
Thanks, fixed.
Silly mistake. Best, Tom

If Snow had practiced in 2020 he would not have been able to do post-mortem examinations. Let's call it medical progress...
stream.gigaohm.bio seems to be ironing out server problems but the same PCR video is available on https://rumble.com/v53wn4y
Couey recently did a very good video on PCR. Start at 23:50 as he always has long intros. https://stream.gigaohm.bio/w/3442q71n6uzwMckdXtxa7N
