Descriptive differences in the household contact population. (A) Baseline (study day 1) viral load of index cases in the standard of care (SOC) and IFNβ-1a treatment (IFN) arms in the household contact (HC) (SOC: n = 142. IFN: n = 147) population, with data present as median (circle) with interquartile range (whiskers). (B) Viral load of household contacts who test positive for SARS-CoV-2 in the SOC and IFN treatment arms in the (SOC: n = 66, IFN: n = 64) with data presented as median (circle) and interquartile range at each study visit.
