• [Pre-print, not peer-reviewed] Within households in Norway, the secondary attack rate of the SARS-CoV-2 B.1.1.7 lineage was 60% higher than that of other variants. The study used contact tracing data from 415 index cases and 2,718 of their close contacts from January 4 to February 28, 2021 to estimate transmissibility and found an absolute increase in the reproduction number of 0.19 compared to other variants.
