Abbreviations: COVID-19 = coronavirus disease 2019; Ct = cycle threshold; F = female; M = male; RT-PCR = reverse transcription–polymerase chain reaction; SOB = shortness of breath.
* E and N genes are gene targets used to detect infection with SARS-CoV-2, the virus that causes COVID-19. One or both of the N1 and N2 gene targets must be detected with a Ct value ≤37 for a positive result. Lower Ct values indicate higher concentrations of SARS-CoV-2. RNAse P is a control that is used to assess specimen quality. Ct values ≤37 indicate the presence of human RNAse P gene.
† Patient B was retested with RT-PCR on hospital admission.
