Sensitivity of RT-PCR for detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) across the COVID-19 disease time course from infection. The approximately 3.5-day period during which students surveilled in the study by Tian et al are likely to first test positive spans a rapid rise in viral load early in disease. Sensitivity when sampling only symptomatic cases (green) is based on Miller et al, He et al,, and Qin et al using the approach of Wells et al. Sensitivity when sampling currently asymptomatic cases (blue) is based on data from Hellewell et al, He et al,, and Qin et al using the approach of Wells et al.
