• [Pre-print, not peer-reviewed] Secondary attack rates (SARs) were 17-37% in three kindergarten schools in Germany during three SARS-CoV-2 outbreaks likely caused by the B.1.1.7 variant. A majority (>80%) of secondary cases occurred within 7 days. The pooled household SAR was 37% after excluding single-occupant households and households with another possible index case. Notably, the attack rate among household child contacts was similar to household adult contacts (39% vs 32%).
