Regarding Covid-19 tests: “A number of firms have developed cheap, paper-strip tests for coronavirus that report results at-home in about 15 minutes but they have yet to be approved for use by the FDA because the FDA appears to be demanding that all tests reach accuracy levels similar to the PCR test. This is another deadly FDA mistake.” The point here is to compare testing regimes rather than tests. Also check out this useful comparison of infected vs infectious.
