If a diagnostic test correctly identified 100% of all positive results, it would be as sensitive as possible. This does not alter our adherence to PLOS ONE policies on sharing data and materials. IMPORTANCE Rapid antigen detection devices for SARS-CoV-2 represent a valuable tool for monitoring the spread of infection. Test sensitivity indicates the ability of the test to correctly identify patients that have the disease. These tests inform researchers and health providers of the presence of the pathogen, either by amplifying and detecting its genetic material or identifying unique markers of the pathogen itself. Now the probability that the Governor is infected is 9/58 = 15%, much lower than before. 10.1371/journal.pone.0242958 Of these, 95% = 9 will test positive.
