Individual test results. Yet recent studies raise questions about the tests'. Many of these are somewhat technical, but still readable. It can be calculated using the equation: sensitivity=number of true positives/ (number of true positives+number of false negatives). The clinical sensitivity of SARS-CoV-2 RT-PCR testing was only moderate at best. This does not alter our adherence to PLOS ONE policies on sharing data and materials.

Of these, the fraction who are infected, which we can interpret as the probability that a given person who tests positive is actually one of the infected is $$ { aP \over aP + (1 - b)(N-P) } $$, We can express this formula in terms of probabilities instead of population sizes.
