On Dr. Seheult’s MedCram channel, Dr. Michael Mina (Harvard) explains what’s wrong with COVID19 testing today, and how to change it from what he calls “the Nespresso model” to “the instant coffee model”: a less sensitive but very inexpensive ($1 a test) saliva-based paper reagent strip test that gives answers in 15 minutes and could feasibly be used for daily screening. This test will be less sensitive than RT-PCR (which costs dozens of times as much) but gives a feasible means of detecting the people with the highest viral load, most likely to be infectious. Thus, for people in high-risk professions and settings, one could conceivably carry out daily screening.
