The interview covers this to an extent, the reason is a lack of appreciation of the potential and an overestimation of the complexity. It’s a somewhat complicated thing to multiplex all the samples correctly, it’s too complex a scheme for an individual lab scientist to do, it either requires a robot or some form of semi automation, I think in Rwanda they were using a smartphone app to tell the scientists which batch to put each sample in. I think that if you could convince the worlds public health bodies, and we can get saliva sampling off the ground in combination you could get to the levels of testing needed to actually do national level surveillance.
