The probability of positive RT-qPCR given (1) the proportion of daily TF that are positive in a weekly pool (primary x-axis and the blue colored curve) and (2) the number of individual daily TF tested (secondary x-axis (top) and all the black colored curves). The individual black colored lines are the different scenarios where only 1 (P + TF = 1) to 7 (P + TF = 7) daily TF are positive in that week
