Status sensitivity of each test platform relative to viral culture positivity. Bars indicate the 95% confidence interval around the observed proportion. Prepositive (n = 31) refers to samples taken on days before the first viral culture-positive sample collected from each individual. Positive (n = 153) refers to samples taken on days for which viral culture results were positive. Postpositive (n = 126) refers to samples taken on days with negative viral culture results that occur after the first positive culture result. Abbreviation: RT-qPCR, quantitative reverse transcription polymerase chain reaction.
