High frequency sample collection cohort at UCSF. A-B) Patient-specific relative tissue contributions for SARS-CoV-2 patients (A) and other RNA-virus infection patients (B). Triangles indicate sampling times. C) Heatmaps of Bray-Curtis dissimilarity. D) Scatterplot of patient-specific Bray-Curtis dissimilarity (left) and boxplot of Bray-Curtis dissimilarity between cfDNA tissue proportions from samples collected from either the same day (within 24 hours), the same person (but not within 24 hours), or from all patients (right). E) Comparison of tissue fraction of four cell and tissue types (neutrophil, erythroblast, lung and liver) between SARS-CoV-2 positive patients and other RNA-virus positive patients. * : p-value < 0.05; ** : p-value < 0.01; *** : p-value < 0.001 (p-values calculated using a Wilcoxon test)
