Title: Susceptibility and infectiousness of children and adults with SARS-CoV-2 variant B.1.1.7 deduced from three daycare centre outbreaks and related household situations; Germany, 2021 Cord-id: ydcvnypm Document date: 2021_5_17
ID: ydcvnypm
Snippet: We investigated three SARS-CoV-2 variant B.1.1.7 kindergarten outbreaks and related household situations. Despite group cohorting, cases occurred in almost all groups, i.e. also among persons without close contact. Secondary attack rates (SAR) of children were similar to adults (day care: 23% vs. 30%; p=0.15; households: 32% vs. 39%; p=0.27), and also child-induced household outbreaks led to similar SAR compared to adults. With the advent of B.1.1.7, susceptibility and infectiousness of children

With the advent of B.1.1.7, susceptibility and infectiousness of children and adults seem to converge.
