Fig. 1 — a Days between index symptom onset and household contact symptom onset for the indicated clades. “Non-VOC” includes all lineages not designated as a WHO variant of concern. No Beta variant transmission pairs were analyzed. b Days between symptom onset and collection of the sequenced specimen for the index case. Index cases from MHome are indicated in teal, and index cases from HIVE are indicated in red. Omicron had a shorter time between index symptom onset and sample collection for sequencing than non-VOC (ANOVA, df = 3, F = 8.138, p < 0.001) and Alpha. HIVE households had a shorter time than MHome households (ANOVA, df = 1, F = 15.363, p < 0.001). c RT-qPCR cycle threshold values (inverted y-axis) for all specimens collected from index cases. Sequenced specimens are indicated with filled circles.
