<p>The number of sequences was scaled to 3 million per sample before comparisons were made between groups. (A) The average numbers of viral sequences found in plasma and NP samples from the subjects are represented by gray bars for samples from afebrile children and black bars for samples from febrile children. The percentage of samples in each group for which 0, 1, 2, 3, 4, or 5 viruses was detected is plotted for (B) sequencing data and (C) PCR data.</p
